WPF - How can I place a usercontrol over an AdornedElementPlaceholder?

- by Kevin

I'm trying to get the validation to not show through my custom modal dialog. I've tried setting the zindex of the dialog and and of the elements in this template. Any ideas? This is coming from a validation template: <ControlTemplate x:Key="ValidationTemplate"> <DockPanel> <TextBlock Foreground="Red" FontSize="20" Panel.ZIndex="-10">!</TextBlock> <Border Name="validationBorder" BorderBrush="Red" BorderThickness="2" Padding="1" CornerRadius="3" Panel.ZIndex="-10"> <Border.Resources> <Storyboard x:Key="_blink"> <ColorAnimationUsingKeyFrames AutoReverse="True" BeginTime="00:00:00" Storyboard.TargetName="validationBorder" Storyboard.TargetProperty="(Border.BorderBrush).(SolidColorBrush.Color)" RepeatBehavior="Forever"> <SplineColorKeyFrame KeyTime="00:00:1" Value="#00FF0000"/> </ColorAnimationUsingKeyFrames> </Storyboard> </Border.Resources> <Border.Triggers> <EventTrigger RoutedEvent="FrameworkElement.Loaded"> <BeginStoryboard Storyboard="{StaticResource _blink}" /> </EventTrigger> </Border.Triggers> <AdornedElementPlaceholder/> </Border> </DockPanel> </ControlTemplate> The dialog: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Class="GunMiser.Controls.PendingChangesConfirmationDialog" Height="768" Width="1024" mc:Ignorable="d"> <Grid Background="White"> <Rectangle x:Name="MainRectangle" Margin="0,0,0,0" Style="{DynamicResource UserControlOverlayRectangleStyle}" Opacity="0.85"/> <Border Margin="288,250,278,288" Background="#FF868686" BorderBrush="Black" BorderThickness="1"> <Border.Effect> <DropShadowEffect Color="#FFB6B2B2"/> </Border.Effect> <TextBlock x:Name="textBlockMessage" Margin="7,29,7,97" TextWrapping="Wrap" d:LayoutOverrides="VerticalAlignment" TextAlignment="Center"/> </Border> <Button x:Name="OkButton" Click="OkButton_Click" Margin="313,0,0,328" VerticalAlignment="Bottom" Height="24" Content="Save Changes" Style="{DynamicResource GunMiserButtonStyle}" HorizontalAlignment="Left" Width="103"/> <Button Click="CancelButton_Click" Margin="453.294,0,456,328" VerticalAlignment="Bottom" Height="24" Content="Cancel Changes" Style="{DynamicResource GunMiserButtonStyle}"/> <Button Click="CancelActionButton_Click" Margin="0,0,304,328" VerticalAlignment="Bottom" Height="24" Content="Go Back" Style="{DynamicResource GunMiserButtonStyle}" HorizontalAlignment="Right" Width="114.706"/> </Grid> </UserControl> And the overall window is: <Window x:Class="GunMiser.Views.Shell" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:cal="http://www.codeplex.com/CompositeWPF" xmlns:controls="clr-namespace:GunMiser.Controls;assembly=GunMiser.Controls" Title="Gun Miser" Height="768" Width="1024"> <Canvas> <controls:PendingChangesConfirmationDialog x:Name="PendingChangesConfirmationDialog" HorizontalAlignment="Stretch" Margin="0,0,0,0" VerticalAlignment="Stretch" Width="1008" Height="730" Visibility="Collapsed" Panel.ZIndex="100" /> <ContentControl x:Name="FilterRegion" cal:RegionManager.RegionName="FilterRegion" Width="326" Height="656" Canvas.Top="32" VerticalAlignment="Top" HorizontalAlignment="Left" /> <ContentControl Name="WorkspaceRegion" cal:RegionManager.RegionName="WorkspaceRegion" Width="678" Height="726" Canvas.Left="330" VerticalAlignment="Top" HorizontalAlignment="Left"/> <Button Click="GunsButton_Click" Width="75" Height="25" Content="Guns" Canvas.Top="3" Style="{DynamicResource GunMiserButtonStyle}"/> <Button Click="OpticsButton_Click" Width="75" Height="25" Content="Optics" Canvas.Left="81" Canvas.Top="3" Style="{DynamicResource GunMiserButtonStyle}"/> <Button Click="SettingsButton_Click" Width="56" Height="28" Content="Settings" Canvas.Left="944" Style="{DynamicResource GunMiserButtonStyle}" HorizontalAlignment="Left" VerticalAlignment="Top"/> <Button Click="AccessoriesButton_Click" Width="75" Height="25" Content="Accessories" Canvas.Left="239" Canvas.Top="3" Style="{DynamicResource GunMiserButtonStyle}"/> <Button Click="AmmunitionButton_Click" Width="75" Height="25" Content="Ammunition" Canvas.Left="160" Canvas.Top="3" Style="{DynamicResource GunMiserButtonStyle}"/> </Canvas> </Window>

app not working

- by pranay

hi, i have written a simple app which would speak out to the user any incoming message. Both programmes seem to work perfectly when i lauched them as two separate pgms , but on keeping them in the same project/package only the speaker programme screen is seen and the receiver pgm doesn't seem to work . Can someone please help me out on it? the speaker pgm is: package com.example.TextSpeaker; import java.util.Locale; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.speech.tts.TextToSpeech; import android.speech.tts.TextToSpeech.OnInitListener; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.Toast; // the following programme converts the msg user to speech public class TextSpeaker extends Activity implements OnInitListener { /** Called when the activity is first created. */ int MY_DATA_CHECK_CODE = 0; public TextToSpeech mtts; public Button button; //public EditText edittext; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button = (Button)findViewById(R.id.button); //edit text=(EditText)findViewById(R.id.edittext); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { //mtts.speak(edittext.getText().toString(), TextToSpeech.QUEUE_FLUSH, null); Toast.makeText(getApplicationContext(), "The service has been started\n Every new message will now be read out", Toast.LENGTH_LONG).show(); } }); Intent myintent = new Intent(); myintent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA); startActivityForResult(myintent, MY_DATA_CHECK_CODE); } protected void onActivityResult(int requestcode,int resultcode,Intent data) { if(requestcode == MY_DATA_CHECK_CODE) { if(resultcode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) { // success so create the TTS engine mtts = new TextToSpeech(this,this); mtts.setLanguage(Locale.ENGLISH); } else { //install the Engine Intent install = new Intent(); install.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); startActivity(install); } } } public void onDestroy(Bundle savedInstanceStatBundle) { mtts.shutdown(); } public void onPause() { super.onPause(); // if our app has no focus if(mtts!=null) mtts.stop(); } @Override public void onInit(int status) { if(status==TextToSpeech.SUCCESS) button.setEnabled(true); } } and the Receiver programme is: package com.example.TextSpeaker; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.speech.tts.TextToSpeech; import android.telephony.SmsMessage; // supports both gsm and cdma import android.widget.Toast; public class Receiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str=""; if(bundle!=null) { // retrive the sms received Object[] pdus = (Object[])bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for(int i=0;i } } }

Insert text into a div from a poput form and rewrite the inserted text with javascript

- by kuswantin

So I read some related questions here before I asked, but can't find the answer to my problem. Hope some javascript master here can find this and bring the light to me. I created another button for nicEdit, a video button and wanted to insert some formatted text into the editor DIV (note: nicEdit has inline DIV, no iframe, no textarea). This is my button, recreated from the image button: var nicVideoOptions = { buttons : { 'video' : {name : __('Insert Video'), type : 'nicEditorVideoButton'} //, tags : ['VIDEO:'] }, iconFiles : {'video' : '../movie.png'} }; var nicEditorVideoButton = nicEditorAdvancedButton.extend({ addPane : function() { this.vi = this.ne.selectedInstance.selElm().parentTag('A'); this.addForm({ '' : {type : 'title', txt : 'Insert Video URL'}, 'href' : {type : 'text', txt : 'URL', 'value' : 'http://', style : {width: '150px'}} },this.vi); }, submit : function(e) { var vidVal = this.inputs['href'].value; if(vidVal == "" || vidVal == "http://") { alert("Enter the video url"); return false; } this.removePane(); if(!this.vi) { var tmp = 'javascript:nicVidTemp();'; this.ne.nicCommand("insertVideo",tmp); // still nothing works //this.vi = this.findElm('VIDEO:','href',tmp); //this.vi = this.setContent('[video:' + this.inputs['href'].value + ']'); //nicEditors.findEditor('edit-comment').setContent('<strong>Some HTML</strong> here'); //this.vi = this.setContent('<strong>Some HTML</strong> here'); insertAtCaret(this.ne.selectedInstance, vidVal); } if(this.vi) { // still nothing works //this.vi.setAttributes({ //vidVal : this.inputs['href'].value //}); //this.vi = this.setContent('[video:' + this.inputs['href'].value + ']'); //this.vi = this.setContent('<strong>Some HTML</strong> here'); } } }); nicEditors.registerPlugin(nicPlugin,nicVideoOptions); The button is there, the form poput like the image button, so it's okay. But can't insert the text into the DIV. The final output will be taken from this: ('[video:' + this.inputs['href'].value + ']') and displayed in the editor DIV as is: [video:http//some.com/video-url] As you see, I am blindly touching everything :) And this insertion is taken from: http://www.scottklarr.com/topic/425/how-to-insert-text-into-a-textarea-where-the-cursor-is/ function insertAtCaret(areaId,text) { var txtarea = document.getElementById(areaId); var scrollPos = txtarea.scrollTop; var strPos = 0; var br = ((txtarea.selectionStart || txtarea.selectionStart == '0') ? "ff" : (document.selection ? "ie" : false ) ); if (br == "ie") { txtarea.focus(); var range = document.selection.createRange(); range.moveStart ('character', -txtarea.value.length); strPos = range.text.length; } else if (br == "ff") strPos = txtarea.selectionStart; var front = (txtarea.value).substring(0,strPos); var back = (txtarea.value).substring(strPos,txtarea.value.length); txtarea.value=front+text+back; strPos = strPos + text.length; if (br == "ie") { txtarea.focus(); var range = document.selection.createRange(); range.moveStart ('character', -txtarea.value.length); range.moveStart ('character', strPos); range.moveEnd ('character', 0); range.select(); } else if (br == "ff") { txtarea.selectionStart = strPos; txtarea.selectionEnd = strPos; txtarea.focus(); } txtarea.scrollTop = scrollPos; } The flow: I click the button, a form popouts, fill the input text box, hit the query button and the text should appear in the editor DIV. I hope I can make myself clear. Any help would be very much appreaciated Thanks

Creating a second login page that automatically logs in the user

I have a login page as follows: <form action="?" method="post" id="frm-useracc-login" name="frm-useracc-login" > <div id="login-username-wrap" > <div class="login-input-item left"> <div class="div-search-label left"> <div id="div-leftheader-wrap"> <p class="a-topheader-infotext left"><strong>Username: </strong></p> </div> </div> <div class="login-input-content left div-subrow-style ui-corner-all"> <input type="text" tabindex="1" name="txt-username" id="txt-username" class="input-txt-med required addr-search-input txt-username left"> </div> </div> </div> <div id="login-password-wrap" > <div class="login-input-item left"> <div class="div-search-label left"> <div id="div-leftheader-wrap"> <p class="a-topheader-infotext left"><strong>Password: </strong></p> </div> </div> <div class="login-input-content left div-subrow-style ui-corner-all"> <input type="password" tabindex="1" name="txt-password" id="txt-password" class="input-txt-med required addr-search-input txt-password left"> </div> </div> </div> <div id="login-btn-bottom" class="centre-div"> <div id="login-btn-right"> <button name="btn-login" id="btn-login" class="btn-med ui-button ui-state-default ui-button-text-only ui-corner-all btn-hover-anim btn-row-wrapper left">Login</button> <button name="btn-cancel" id="btn-cancel" class="btn-med ui-button ui-state-default ui-button-text-only ui-corner-all btn-hover-anim btn-row-wrapper left">Cancel</button><br /><br /> </div> </div> </form> And here my session.controller.php file: Click Here Basically, what I want to do is create a second login page that automatically passes the value to the session controller and logs in. For example, if I go to login-guest.php, I would put the default values for username and password and then have a jquery click event that automatically logs them in using $("#btn-login").trigger('click'); The problem is that the session controller automatically goes back to login.php if the session has timed out and I'm not sure how I could go about achieving this. Any help would be much appreciated!

Very simple, terse and easy GUI programming “frameworks”

- by jetxee

Please list GUI programming libraries, toolkits, frameworks which allow to write GUI apps quickly. I mean in such a way, that GUI is described entirely in a human-readable (and human-writable) plain text file (code) code is terse (1 or 2 lines of code per widget/event pair), suitable for scripting structure and operation of the GUI is evident from the code (nesting of widgets and flow of events) details about how to build the GUI are hidden (things like mainloop, attaching event listeners, etc.) auto-layouts are supported (vboxes, hboxes, etc.) As answers suggest, this may be defined as declarative GUI programming, but it is not necessarily such. Any approach is OK if it works, is easy to use and terse. There are some GUI libraries/toolkits like this. They are listed below. Please extend the list if you see a qualifying toolkit missing. Indicate if the project is crossplatform, mature, active, and give an example if possible. Please use this wiki to discuss only Open Source projects. This is the list so far (in alphabetical order): Fudgets Fudgets is a Haskell library. Platform: Unix. Status: Experimental, but still maintained. An example: import Fudgets main = fudlogue (shellF "Hello" (labelF "Hello, world!" >+< quitButtonF)) GNUstep Renaissance Renaissance allows to describe GUI in simple XML. Platforms: OSX/GNUstep. Status: part of GNUstep. An example below: <window title="Example"> <vbox> <label font="big"> Click the button below to quit the application </label> <button title="Quit" action="terminate:"/> </vbox> </window> HTML HTML-based GUI (HTML + JS). Crossplatform, mature. Can be used entirely on the client side. Looking for a nice “helloworld” example. JavaFX JavaFX is usable for standalone (desktop) apps as well as for web applications. Not completely crossplatform, not yet completely open source. Status: 1.0 release. An example: Frame { content: Button { text: "Press Me" action: operation() { System.out.println("You pressed me"); } } visible: true } Screenshot is needed. Phooey Phooey is another Haskell library. Crossplatform (wxWidgets), HTML+JS backend planned. Mature and active. An example (a little more than a helloworld): ui1 :: UI () ui1 = title "Shopping List" $ do a <- title "apples" $ islider (0,10) 3 b <- title "bananas" $ islider (0,10) 7 title "total" $ showDisplay (liftA2 (+) a b) PythonCard PythonCard describes GUI in a Python dictionary. Crossplatform (wxWidgets). Some apps use it, but the project seems stalled. There is an active fork. I skip PythonCard example because it is too verbose for the contest. Shoes Shoes for Ruby. Platforms: Win/OSX/GTK+. Status: Young but active. A minimal app looks like this: Shoes.app { @push = button "Push me" @note = para "Nothing pushed so far" @push.click { @note.replace "Aha! Click!" } } Tcl/Tk Tcl/Tk. Crossplatform (its own widget set). Mature (probably even dated) and active. An example: #!/usr/bin/env wish button .hello -text "Hello, World!" -command { exit } pack .hello tkwait window . tekUI tekUI for Lua (and C). Platforms: X11, DirectFB. Status: Alpha (usable, but API still evolves). An example: #/usr/bin/env lua ui = require "tek.ui" ui.Application:new { Children = { ui.Window:new { Title = "Hello", Children = { ui.Text:new { Text = "_Hello, World!", Style = "button", Mode = "button", }, }, }, }, }:run() Treethon Treethon for Python. It describes GUI in a YAML file (Python in a YAML tree). Platform: GTK+. Status: work in proress. A simple app looks like this: _import: gtk view: gtk.Window() add: - view: gtk.Button('Hello World') on clicked: print view.get_label() Yet unnamed Python library by Richard Jones: This one is not released yet. The idea is to use Python context managers (with keyword) to structure GUI code. See Richard Jones' blog for details. with gui.vertical: text = gui.label('hello!') items = gui.selection(['one', 'two', 'three']) with gui.button('click me!'): def on_click(): text.value = items.value text.foreground = red XUL XUL + Javascript may be used to create stand-alone desktop apps with XULRunner as well as Mozilla extensions. Mature, open source, crossplatform. <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window id="main" title="My App" width="300" height="300" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <caption label="Hello World"/> </window> Thank your for contributions!

I created an application which loads random layour from resources and I have problem because program shows random layout and closes , sometimes after 2 times and sometimes after a dozen, and I dont know where is a problem, I tried to run it on my phone and I added in the manifest write_external_storage permission, and still the same error.Please help me, and try to resolve this problem. here is my code in : java : package ka.ka.ka; import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class KAMASActivity extends Activity implements OnClickListener { Button button1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button1 = (Button) findViewById(R.id.button1) ; button1.setOnClickListener(this); } @Override public void onClick(View v) { int min = 1; int max = 6; int i1=0; Random r = new Random(); i1 = r.nextInt(max - min + 1) + min; if(i1==1){setContentView(R.layout.image1); button1 = (Button) findViewById(R.id.button1) ; button1.setOnClickListener(this);} if(i1==2){setContentView(R.layout.image2); button1 = (Button) findViewById(R.id.button1) ; button1.setOnClickListener(this);} if(i1==3){setContentView(R.layout.image3);

Our Look at Opera 10.50 Web Browser

- by Asian Angel

Everyone has been talking about the newest version of Opera recently but perhaps you have not looked at it too closely yet. Today we will take a look at 10.50 and let you see what this “new browser” is all about. The New Engines Carakan JavaScript Engine: Runs web applications up to 7 times faster than its predecessor Futhark Vega Graphics Library: Enables super fast and smooth graphics on everything from tab switching to webpage animation Presto 2.5: Provides support for HTML5, CSS2.1 and the latest CSS3 standards A Look at the Features Available If you have installed or used older versions of Opera before then the default look after a clean install will probably seem rather different. The main differences in appearance are mainly located within the “glass border” areas of the browser. The “Speed Dial” setup looks and works just as well as in previous versions. You can set a favorite wallpaper or image as your background and choose the number of “dials” using the “Configure Speed Dial Command”. One of the “standout” differences is the “O Button”. All of the menus have been condensed into this single access point but it only takes a few moments to find what you are looking for. If you have used the style before in earlier versions of Opera some of the items have been moved around. For those who prefer the “Menu Bar” that can be easily restored using the “Show Menu Bar Command”. If desired you can actually “extend” the “Tab Bar” downwards to display thumbnails of your open tabs. Just use your mouse to grab the bottom of the “Tab Bar” and adjust it to suit your personal needs. The only problem with this feature is that it will quickly use up a good sized portion of your available UI and browser window space. The “Password Manager” is ready to access when needed…the background for the button will turn a shiny metallic blue when you open a webpage that you have “Login Information” saved for. One of the new features is a small “Recycle Bin Button” in the upper right corner. Clicking on this will display a list of recently closed tabs letting you have easy access to any tabs that you may have accidentally closed. This is definitely a great feature to have as an easy access button. For those who were used to how the “Zoom Feature” looked before it has a new “look” to it. Instead of the pop-up menu-type listing of “view sizes” present before you now have a slider button that you can use to adjust the zooming level. For our default setup here the “Sidebar Panels” available were: “Bookmarks, Widgets, Unite, Notes, Downloads, History, & Panels”. Additional panels such as “Links, Windows, Search, Info, etc.” are available if you want and/or need them (accessible using the “Panels Plus Sign Button”). The “Opera Link Button” makes it easy for you to synchronize your “Speed Dial, Bookmarks, Personal Bar, Custom Searches, History & Notes”. Note: “Opera Link” requires an account and can be signed up for using the link provided below. Want to share files with your family and friends? “Unite” allows you to do that and more. With “Unite” you can: “Stream Music, Show Photo Galleries, Share Files and/or Folders, & host webpages directly from your browser”. We have a more in-depth look at “Unite” in our article here. Note: Use of “Unite” requires an Opera account. Got a slow internet connection? “Opera Turbo” can help with that by running the web traffic through their “compression servers” to speed up your web browsing. Keep in mind that “Opera Turbo” will not engage if you are accessing a secure website (i.e. your bank’s website) thus preserving your security. Note: “Opera Turbo” can be set up to automatically detect slow internet connections (i.e. crowded Wi-Fi in a cafe). Opera has a built-in “Private Browsing Mode” now for those who prefer anonymous browsing and want to keep the “history records clean” on their computer. To access it go to “Tabs and windows” and select “New private tab” or “New private window” as desired. When you open your new “Private Tab or Window” you will see the following message with details on how Opera will handle browsing information and a large “door hanger symbol”. Notice that the one tab is locked into “Private Browsing Mode” while the others are still working in “Regular Browsing Mode”. Very nice! A miniature version of the “door hanger symbol” will be present on any tab that is locked into “Private Browsing Mode”. If you are using Windows 7 then you will love how things look from your “Taskbar”. Here you can see four very nice looking thumbnails for the tabs that we had open. All that you have to do is click on the desired thumbnail… The “Context Menu” looks just as lovely as the thumbnails and definitely has some terrific functionality built into it. Add Enhanced Aero Capability If you love “Aero” and want more for your new Opera install then we have the perfect theme for you. The theme’s name is Z1-AV69 and once you have downloaded it you will need to place it in the “Skins Subfolder” in Opera’s “Program Files Folder”. Note: For our example we used version 1.10 but version 2.00 is now available (link provided below). Once you have restarted Opera, go to the “O Menu” and select “Appearance”. When the “Appearance Window” opens click on “Z1-Glass Skin” and then click “OK”. All of a sudden you will have more “Aero Goodness” to enjoy. Compare this screenshot with the one at the top of this article…the only part that is not transparent now is the browser window area itself. Want even more “Aero Goodness”? Right click on the “Tab Bar” and set “Tab Bar Placement” to “Left”. Note: You can achieve the same effect by setting the “Tab Bar Placement” to “Right”. With the “Speed Dial” visible you will be able to see your wallpaper with ease. While this is obviously not for everyone it does make for a great visual trick. Portable Versions Perhaps you need this wonderful new version of Opera to go with you wherever you do during the day. Not a problem…just visit the Opera USB website to choose a version that works best for you. You can select from “Zip or Exe” setup files and if needed update an older portable version using a “Zipped Update Files Package”. If you are updating an older version keep in mind that you will need to delete the old “OperaUSB.exe. File” due to changes with the new setup files. During our tests updating older portable versions went well for the most part but we did experience a few “odd UI quirks” here and there…so we recommend setting up a clean install if possible. Conclusion The new 10.50 release is a pleasure to use and is a recommended install for your system. Whether you are considering trying Opera for the first time or have been using it for a bit we think that you will pleased with everything that the 10.50 release has to offer.

Remote Desktop to Your Azure Virtual Machine

- by Shaun

The Windows Azure Team had just published their new development portal this week and the SDK 1.3. Within this new release there are a lot of cool feature available. The one I’m looking forward to is Remote Desktop Access to your running Windows Azure Virtual Machine. Configuration Remote Desktop Access It would be very simple to make the azure service enable the remote desktop access. First of all let’s create a new windows azure project from the Visual Studio. In this example I just created a normal MVC 2 web role without any modifications. Then we right-click the azure project node in the solution explorer window and select “Publish”. Then let’s select the “Deploy your Windows Azure project to Windows Azure” on the top radio button. And then select the credential, deployment service/slot, storage and label as susal. You must have the Management API Certificates uploaded to your Windows Azure account, and install the certification on you machine before in order to use this one-click deployment feature. If you are familiar with this dialog you will notice that there’s a linkage named “Configure Remote Desktop connections”. Here is where you need to make this service enable the remote desktop feature. After clicked this link we will set the configuration of the remote desktop access authorization information. There are 4 steps we need to do to configure our access. Certificates: We need either create or select a certificate file in order to encypt the access cerdenticals. In this example I will use the certificate file for my Management API. Username: The remote desktop user name to access the virtual machine. Password: The password for the access. Expiration: The access cerdentals would be expired after 1 month by default but we can amend here. After that we clicked the OK button to back to the publish dialog. The next step is to back to the new windows azure portal and navigate to the hosted services list. I created a new hosted service and upload the certificate file onto this service. The user name and password access to the azure machine must be encrypted from the local machine, and then send to the windows azure platform, then decrypted on the azure side by the same file. This is why we need to upload the certificate file onto azure. We navigated to the “Hosted Services, Storage Accounts & CDN"” from the left panel and created a new hosted service named “SDK13” and selected the “Certificates” node. Then we clicked the “Add Certificates” button. Then we select the local certificate file and the password to install it into this azure service. The final step would be back to our Visual Studio and in the pulish dialog just click the OK button. The Visual Studio will upload our package and the configuration into our service with the remote desktop settings. Remote Desktop Access to Azure Virtual Machine All things had been done, let’s have a look back on the Windows Azure Development Portal. If I selected the web role that I had just published we can see on the toolbar there’s a section named “Remote Access”. In this section the Enable checkbox had been checked which means this role has the Remote Desktop Access feature enabled. If we want to modify the access cerdentals we can simply click the Configure button. Then we can update the user name, password, certificates and the expiration date. Let’s select the instance node under the web role. In this case I just created one instance for demo. We can see that when we selected the instance node, the Connect button turned enabled. After clicked this button there will be a RDP file downloaded. This is a Remote Desctop configuration file that we can use to access to our azure virtual machine. Let’s download it to our local machine and execute. We input the user name and password we specified when we published our application to azure and then click OK. There might be some certificates warning dislog appeared. This is because the certificates we use to encryption is not signed by a trusted provider. Just select OK in these cases as we know the certificate is safty to us. Finally, the virtual machine of Windows Azure appeared. A Quick Look into the Azure Virtual Machine Let’s just have a very quick look into our virtual machine. There are 3 disks available for us: C, D and E. Disk C: Store the local resource, diagnosis information, etc. Disk D: System disk which contains the OS, IIS, .NET Frameworks, etc. Disk E: Sotre our application code. The IIS which hosting our webiste on Azure. The IP configuration of the azure virtual machine. Summary In this post I covered one of the new feature of the Azure SDK 1.3 – Remote Desktop Access. We can set the access per service and all of the instances of this service could be accessed through the remote desktop tool. With this feature we can deep into the virtual machines of our instances to see the inner information such as the system event, IIS log, system information, etc. But we should pay attention to modify the system settings. 2 reasons from what I know for now: 1. If we have more than one instances against our service we should ensure that all system settings we modifed are applied to all instances/virtual machines. Otherwise, as the machines are under the azure load balance proxy our application process may doesn’t work due to the defferent settings between the instances. 2. When the virtual machine encounted some problem and need to be translated to another physical machine all settings we made would be disappeared.

Customize the Five Windows Folder Templates

- by Mark Virtue

Are you’re particular about the way Windows Explorer presents each folder’s contents? Here we show you how to take advantage of Explorer’s built-in templates, which cuts down the time it takes to do customizations. Note: The techniques in this article apply to Windows XP, Vista, and Windows 7. When opening a folder for the first time in Windows Explorer, we are presented with a standard default view of the files and folders in that folder. It may be that the items are presented are perfectly fine, but on the other hand, we may want to customize the view. The aspects of it that we can customize are the following: The display type (list view, details, tiles, thumbnails, etc) Which columns are displayed, and in which order The widths of the visible columns The order in which the files and folders are sorted Any file groupings Thankfully, Windows offers us a shortcut. A particular folder’s settings can be used as a “template” for other, similar folders. In fact, we can store up to five separate sets of folder presentation configurations. Once we save the settings for a particular template, that template can then be applied to other folders. Customize Your First Folder We’ll start by setting up the first of our templates – the default one. Once we create this template and apply it, the vast majority of the folders in our file system will change to match it, so it’s important that we set it up very carefully. The first step in creating and applying the template is to customize one folder with the settings that all the rest will have. Choose a folder that is typical of the folders that you wish to have this default template. Select it in Windows Explorer. To ensure that it is a suitable candidate, right-click the folder name and select Properties, then go to the Customize tab. Ensure that this folder is marked as General Items. If it is not, either choose a different folder or select General Items from the list. Click OK. Now we’re ready to customize our first folder. Changing the way one single folder is presented is straightforward. We start with the folder’s display type. Click the Change your view button in the top-right corner of every Explorer window. Each time you click the button, the folder’s view cycles to the next view type. Alternatively you can click the little down-arrow next to the button to see all the display types at once, and select the one you want. Click the view you want, or drag the slider next to the one you want. If you have chosen Details, then the next thing you may wish to change is which columns are displayed, and the order of these. To choose which columns are displayed, simply right-click on any column heading. A list of the columns currently being display appears. Simply uncheck a column if you don’t want it displayed, and check the columns that you want displayed. If you want some information displayed about your files that is not listed here, then click the More… button for a full list of file attributes. There’s a lot of them! To change the order of the columns that are currently being displayed, simply click on a column heading and drag it to where you think it should be. To change the width of a column, click the line that represents the right-hand edge of the column and drag it left or right. To sort by a column, click once on that column. To reverse the sort-order, click that same column again. To change the groupings of the files in the folder, right-click in a blank area of the folder, select Group by, and select the appropriate column. Apply This Default Template to All Similar Folders Once you have the folder exactly the way you want it, we now use this folder as our default template for most of the folders in our file system. To do this, ensure that you are still in the folder you just customized, and then, from the Organize menu in Explorer, click on Folder and search options. Then select the View tab and click the Apply to Folders button. After you’ve clicked OK, visit some of the other folders in your file system. You should see that most have taken on these new settings. What we’ve just done, in effect, is we have customized the General Items template. This is one of five templates that Windows Explorer uses to display folder contents. The five templates are called (in Windows 7): General Items Documents Pictures Music Videos When a folder is opened, Windows Explorer examines the contents to see if it can automatically determine which folder template to use to display the folder contents. If it is not obvious that the folder contents falls into any of the last four templates, then Windows Explorer chooses the General Items template. That’s why most of the folders in your file system are shown using the General Items template. Changing the Other Four Templates If you want to adjust the other four templates, the process is very similar to what we’ve just done. If you wanted to change the “Music” template, for example, the steps would be as follows: Select a folder that contains music items Apply the existing Music template to the folder (even if it doesn’t look like you want it to) Customize the folder to your personal preferences Apply the new template to all “Music” folders A fifth step would be: When you open a folder that contains music items but is not automatically displayed using the Music template, you manually select the Music template for that folder. First, select a folder that contains music items. It will probably be displayed using the existing Music template: Next, ensure that it is using the Music template. If it’s not, then manually select the Music template. Next, customize the folder to suit your personal preferences (here we’ve added a couple of columns, and sorted by Artist). Now we can set this view to be our Music template. Choose Organize, then the View tab, and click the Apply to Folders button. Note: The only folders that will inherit these settings are the ones that are currently (or will soon be) using the Music template. Now, if you have any folder that contains music items, and you want it to inherit all of these settings, then right-click the folder name, choose Properties, and select that this folder should use the Music template. You can also cehck the box entitled Also apply this template to all subfolders if you want to save yourself even more time with all the sub-folders. Conclusion It’s neat to be able to set up templates for your folder views like this. It’s a shame that Microsoft didn’t take the concept just a little further and allow you to create as many templates as you want.

Silverlight MEF – Download On Demand

- by PeterTweed

Take the Slalom Challenge at www.slalomchallenge.com! A common challenge with building complex applications in Silverlight is the initial download size of the xap file. MEF enables us to build composable applications that allows us to build complex composite applications. Wouldn’t it be great if we had a mechanism to spilt out components into different Silverlight applications in separate xap files and download the separate xap file only if needed? MEF gives us the ability to do this. This post will cover the basics needed to build such a composite application split between different silerlight applications and download the referenced silverlight application only when needed. Steps: 1. Create a Silverlight 4 application 2. Add references to the following assemblies: System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll 3. Add a new Silverlight 4 application called ExternalSilverlightApplication to the solution that was created in step 1. Ensure the new application is hosted in the web application for the solution and choose to not create a test page for the new application. 4. Delete the App.xaml and MainPage.xaml files – they aren’t needed. 5. Add references to the following assemblies in the ExternalSilverlightApplication project: System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll 6. Ensure the two references above have their Copy Local values set to false. As we will have these two assmblies in the original Silverlight application, we will have no need to include them in the built ExternalSilverlightApplication build. 7. Add a new user control called LeftControl to the ExternalSilverlightApplication project. 8. Replace the LayoutRoot Grid with the following xaml: <Grid x:Name="LayoutRoot" Background="Beige" Margin="40" > <Button Content="Left Content" Margin="30"></Button> </Grid> 9. Add the following statement to the top of the LeftControl.xaml.cs file using System.ComponentModel.Composition; 10. Add the following attribute to the LeftControl class [Export(typeof(LeftControl))] This attribute tells MEF that the type LeftControl will be exported – i.e. made available for other applications to import and compose into the application. 11. Add a new user control called RightControl to the ExternalSilverlightApplication project. 12. Replace the LayoutRoot Grid with the following xaml: <Grid x:Name="LayoutRoot" Background="Green" Margin="40" > <TextBlock Margin="40" Foreground="White" Text="Right Control" FontSize="16" VerticalAlignment="Center" HorizontalAlignment="Center" ></TextBlock> </Grid> 13. Add the following statement to the top of the RightControl.xaml.cs file using System.ComponentModel.Composition; 14. Add the following attribute to the RightControl class [Export(typeof(RightControl))] 15. In your original Silverlight project add a reference to the ExternalSilverlightApplication project. 16. Change the reference to the ExternalSilverlightApplication project to have it’s Copy Local value = false. This will ensure that the referenced ExternalSilverlightApplication Silverlight application is not included in the original Silverlight application package when it it built. The ExternalSilverlightApplication Silverlight application therefore has to be downloaded on demand by the original Silverlight application for it’s controls to be used. 1. In your original Silverlight project add the following xaml to the LayoutRoot Grid in MainPage.xaml: <Grid.RowDefinitions> <RowDefinition Height="65*" /> <RowDefinition Height="235*" /> </Grid.RowDefinitions> <Button Name="LoaderButton" Content="Download External Controls" Click="Button_Click"></Button> <StackPanel Grid.Row="1" Orientation="Horizontal" HorizontalAlignment="Center" > <Border Name="LeftContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border> <Border Name="RightContent" Background="Red" BorderBrush="Gray" CornerRadius="20"></Border> </StackPanel> The borders will hold the controls that will be downlaoded, imported and composed via MEF when the button is clicked. 2. Add the following statement to the top of the MainPage.xaml.cs file using System.ComponentModel.Composition; 3. Add the following properties to the MainPage class: [Import(typeof(LeftControl))] public LeftControl LeftUserControl { get; set; } [Import(typeof(RightControl))] public RightControl RightUserControl { get; set; } This defines properties accepting LeftControl and RightControl types. The attrributes are used to tell MEF the discovered type that should be applied to the property when composition occurs. 17. Add the following event handler for the button click to the MainPage.xaml.cs file: private void Button_Click(object sender, RoutedEventArgs e) { DeploymentCatalog deploymentCatalog = new DeploymentCatalog("ExternalSilverlightApplication.xap"); CompositionHost.Initialize(deploymentCatalog); deploymentCatalog.DownloadCompleted += (s, i) => { if (i.Error == null) { CompositionInitializer.SatisfyImports(this); LeftContent.Child = LeftUserControl; RightContent.Child = RightUserControl; LoaderButton.IsEnabled = false; } }; deploymentCatalog.DownloadAsync(); } This is where the magic happens! The deploymentCatalog object is pointed to the ExternalSilverlightApplication.xap file. It is then associated with the CompositionHost initialization. As the download will be asynchronous, an eventhandler is created for the DownloadCompleted event. The deploymentCatalog object is then told to start the asynchronous download. The event handler that executes when the download is completed uses the CompositionInitializer.SatisfyImports() function to tell MEF to satisfy the Imports for the current class. It is at this point that the LeftUserControl and RightUserControl properties are initialized with composed objects from the downloaded ExternalSilverlightApplication.xap package. 18. Run the application click the Download External Controls button and see the controls defined in the ExternalSilverlightApplication application loaded into the original Silverlight application. Congratulations! You have implemented download on demand capabilities for composite applications using the MEF DeploymentCatalog class. You are now able to segment your applications into separate xap file for deployment.

How to Use the Signature Editor in Outlook 2013

- by Lori Kaufman

The Signature Editor in Outlook 2013 allows you to create a custom signature from text, graphics, or business cards. We will show you how to use the various features of the Signature Editor to customize your signatures. To open the Signature Editor, click the File tab and select Options on the left side of the Account Information screen. Then, click Mail on the left side of the Options dialog box and click the Signatures button. For more details, refer to one of the articles mentioned above. Changing the font for your signature is pretty self-explanatory. Select the text for which you want to change the font and select the desired font from the drop-down list. You can also set the justification (left, center, right) for each line of text separately. The drop-down list that reads Automatic by default allows you to change the color of the selected text. Click OK to accept your changes and close the Signatures and Stationery dialog box. To see your signature in an email, click Mail on the Navigation Bar. Click New Email on the Home tab. The Message window displays and your default signature is inserted into the body of the email. NOTE: You shouldn’t use fonts that are not common in your signatures. In order for the recipient to see your signature as you intended, the font you choose also needs to be installed on the recipient’s computer. If the font is not installed, the recipient would see a different font, the wrong characters, or even placeholder characters, which are empty square boxes. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can save it as a draft if you want, but it’s not necessary. If you decide to use a font that is not common, a better way to do so would be to create a signature as an image, or logo. Create your image or logo in an image editing program making it the exact size you want to use in your signature. Save the image in a file size as small as possible. The .jpg format works well for pictures, the .png format works well for detailed graphics, and the .gif format works well for simple graphics. The .gif format generally produces the smallest files. To insert an image in your signature, open the Signatures and Stationery dialog box again. Either delete the text currently in the editor, if any, or create a new signature. Then, click the image button on the editor’s toolbar. On the Insert Picture dialog box, navigate to the location of your image, select the file, and click Insert. If you want to insert an image from the web, you must enter the full URL for the image in the File name edit box (instead of the local image filename). For example, http://www.somedomain.com/images/signaturepic.gif. If you want to link to the image at the specified URL, you must also select Link to File from the Insert drop-down list to maintain the URL reference. The image is inserted into the Edit signature box. Click OK to accept your changes and close the Signatures and Stationery dialog box. Create a new email message again. You’ll notice the image you inserted into the signature displays in the body of the message. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You may want to put a link to a webpage or an email link in your signature. To do this, open the Signatures and Stationery dialog box again. Enter the text to display for the link, highlight the text, and click the Hyperlink button on the editor’s toolbar. On the Insert Hyperlink dialog box, select the type of link from the list on the left and enter the webpage, email, or other type of address in the Address edit box. You can change the text that will display in the signature for the link in the Text to display edit box. Click OK to accept your changes and close the dialog box. The link displays in the editor with the default blue, underlined text. Click OK to accept your changes and close the Signatures and Stationery dialog box. Here’s an example of an email message with a link in the signature. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your contact information into your signature as a Business Card. To do so, click Business Card on the editor’s toolbar. On the Insert Business Card dialog box, select the contact you want to insert as a Business Card. Select a size for the Business Card image from the Size drop-down list. Click OK. The Business Card image displays in the Signature Editor. Click OK to accept your changes and close the Signatures and Stationery dialog box. When you insert a Business Card into your signature, the Business Card image displays in the body of the email message and a .vcf file containing your contact information is attached to the email. This .vcf file can be imported into programs like Outlook that support this format. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your Business Card into your signature without the image or without the .vcf file attached. If you want to provide recipients your contact info in a .vcf file, but don’t want to attach it to every email, you can upload the .vcf file to a location on the internet and add a link to the file, such as “Get my vCard,” in your signature. NOTE: If you want to edit your business card, such as applying a different template to it, you must select a different View other than People for your Contacts folder so you can open the full contact editing window.

Are you reporting Visual Studio 2012 issues to Microsoft correctly?

- by Tarun Arora

Issues you may run into while using Visual Studio need to be reported to the Microsoft Product Team via the Microsoft connect site. The Microsoft team then tries to reproduce the issue using the details provided by you. If the information you provide isn’t sufficient to reproduce the issue the team tries to contact you for specifics, this not only increases the cycle time to resolution but the lack of communication also results in issues not being resolved. So, when I report an issue one part of me tells me to include as much detail about the issue as I can clubbing screen shots, repo steps, system information, visual studio version information,… the other half tells me this is so time consuming, leave it for now and come back to fill all these details later. Reporting a bug but not including the supporting information is an invitation to excuses like … Microsoft has absolutely changed this experience for VS 2012. The Microsoft Visual Studio Feedback tool is designed to simplify the process of providing feedback and reporting issues to Microsoft that you may encounter while using Microsoft Visual Studio 2012. Note – The Microsoft Visual Studio 2012 Feedback client currently only works for VS 2012 and not any other versions of Visual Studio. Setting up the Microsoft Visual Studio 2012 Feedback client Open Visual Studio, from the Tools menu select Extension and Updates. In the Extension and Updates window, click Online from the left pane and search using the text ‘feedback’, download and Install Microsoft Visual Studio 2012 Feedback Tool by following the instructions from the wizard. Note - Restarting Visual Studio after the install is a must! How to report a bug for Visual Studio 2012? Click on the Help menu and choose Report a Bug You should see an icon Microsoft Visual Studio 2012 Feedback Tool come up in the system tray icon area You’ll need to accept the Privacy statement. You have the option of reporting the feedback as private or public. Microsoft works with several Partners, MVP’s and Vendors who get access to early bits of Microsoft products for valuation. This is where it becomes essential to report the feedback privately. I would choose the Public option otherwise. After all if it’s out there in the public, others can discover and add to it easily. You now have the option to report a new issue or add to an existing issue. Should you choose to add to an existing issue you should have the feedback ID of the issue available. This can be obtained from the Microsoft Connect site. For now I am going to focus on reporting a new feedback privately. Filling out the feedback details You will notice that VsInfo.xml and DxDiagOutput.txt are automatically attached as you enter this screen (more on that later). Feedback Type Choose the feedback type from (Performance, Hang, Crash, Other) Note – The record button will only be enabled once you have enabled once you have chosen the feedback type, Bug-repro recording is not available for Windows Server 2008. Effective Title and Description Enter a title that helps us differentiate the bug when it appears in a list, so that we can group it with any related bugs, assign it to a developer more effectively, and resolve it more quickly. Example: Imagine that you are submitting a bug because you tried to install Service Pack 1 and got a message that Visual Studio is not installed even though it is. Helpful: Installed Visual Studio version not detected during Service Pack 1 setup. Not helpful: Service Pack 1 problem. Tip: Write the problem description first, and then distil it to create a title. Example Description: Helpful: When I run Service Pack 1 Setup, I get the message "No Visual Studio version is detected" even though I have Visual Studio 2010 Ultimate and Visual C++ 2010 Express installed on my machine. Even though I uninstalled both editions, and then first reinstalled Ultimate and then Express, I still get the message. Record: Becoming a first class citizen Often a repro report is invaluable to describe and decipher the issue. Please use this feature to send actionable feedback. The record repro feature works differently depending on the feedback type you selected. Please find below details for each recording option. You can start recording simply by selecting a feedback type, and clicking on the “Record” button. When "Performance" is the bug type: When the Microsoft Visual Studio trace recorder starts, perform the actions that show the performance problem you want to report and then click on the "Stop Recording" button as soon as you experience the performance problem. Because the tool optimizes trace collection, you can run it for as long as it takes to show the problem, up to two hours. Note that, you need to stop recording as soon as the performance issue occurs, because the tool captures only the last couple minutes of your actions to optimize the trace collection. After you stop the recording, the tool takes up to two minutes to assemble the data and attach an ETLTrace.zip file to your bug report. The data includes information about Windows events and the Visual Studio code path. Note that, running the Microsoft Visual Studio trace recorder requires elevated user privilege. When "Crash" is the bug type: When the dialog box appears, select the running Visual Studio instance for which you want to show the steps that cause a crash. When the crash occurs, click on the "Stop Record" button. After you do this, two files are attached to your bug report - an AutomaticCrashDump.zip file that contains information about the crash and a ReproSteps.zip file that shows the repro steps. Repro steps are captured by Windows Problem Steps Recorder. Note that, you can pause the recording, and resume later, or for a specific step, you can add additional comments. When "Hang" is the bug type: The process for recording the steps that cause a hang resembles the one for crashes. The difference is, you can even collect a dump file after the VS hangs; start the VSFT either from the system tray or by starting a new instance of VS, select "Hang" as feedback type and click on the "Record" button. You will be prompted which VS to collect dump about, select the VS instance that hanged. VSFT collects a dump file regarding the hang, called MiniDump.zip, and attaches to your bug report. When "Other" is the bug type: When the problem step recorder starts, perform the actions that show the issue you want to report and then choose the "Stop” button. You can pause the recording, and resume later, or for a specific step, you can add additional comments. Once you’re done, ReproSteps.zip is added to your bug report. Pre-attached files It is essential for Microsoft to know what version of the the product are you currently using and what is the current configuration of your system. Note – The total size of all attachments in a bug report cannot exceed 2 GB, and every uncompressed attachment must be smaller than 512 MB. We recommend that you assemble all of your attachments, compress them together into a .zip file, and then attach the .zip file. Taking a screenshot Associate a screen shot by clicking the Take screenshot button, choose either the entire desktop, the specific monitor (useful if you are working in a multi monitor configuration) or the specific window in question. And finally … click Submit If you need further help, more details can be found here. You can view your feedback online by using the following URL “">https://connect.microsoft.com/VisualStudio/SearchResults.aspx?SearchQuery=<feedbackId>” Happy bug logging

WPF: ContentPresenter changing Foreground unexpectedly depending on where styles are located

- by VLTII

Hi, I'm having an issue with the ContentPresenter behaving unexpectedly based on whether the styles are located in the Window.Resources or in a ResourceDictionary. Specifically, I'm setting the Foreground of the default TextBlock to Black, then setting the Foreground value in my default button style to White. If the styles exits on the page like this, they work fine: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero" x:Class="TestBed.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <Style TargetType="{x:Type TextBlock}"> <Setter Property="Foreground" Value="Black" /> </Style> <Style x:Key="ButtonFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1" Margin="2" SnapsToDevicePixels="true"/> </ControlTemplate> </Setter.Value> </Setter> </Style> <LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#F3F3F3" Offset="0"/> <GradientStop Color="#EBEBEB" Offset="0.5"/> <GradientStop Color="#DDDDDD" Offset="0.5"/> <GradientStop Color="#CDCDCD" Offset="1"/> </LinearGradientBrush> <SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/> <Style TargetType="{x:Type Button}"> <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/> <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/> <Setter Property="BorderThickness" Value="1"/> <Setter Property="Foreground" Value="White"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Padding" Value="1"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}"> <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/> </Microsoft_Windows_Themes:ButtonChrome> <ControlTemplate.Triggers> <Trigger Property="IsKeyboardFocused" Value="true"> <Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="ToggleButton.IsChecked" Value="true"> <Setter Property="RenderPressed" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Foreground" Value="#ADADAD"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <StackPanel x:Name="LayoutRoot"> <Button Content="Button" /> </StackPanel> </Window> But if I move those same styles over to a ResourceDictionary, the Foreground of the button switches to black.

Problem with my whiteboard application

- by swift

I have to develop a whiteboard application in which both the local user and the remote user should be able to draw simultaneously, is this possible? If possible then any logic? I have already developed a code but in which i am not able to do this, when the remote user starts drawing the shape which i am drawing is being replaced by his shape and co-ordinates. This problem is only when both draw simultaneously. any idea guys? Here is my code class Paper extends JPanel implements MouseListener,MouseMotionListener,ActionListener { static BufferedImage image; int bpressed; Color color; Point start; Point end; Point mp; Button elipse=new Button("elipse");

ContentPresenter changing Foreground unexpectedly depending on where styles are located

- by VLTII

Hi, I'm having an issue with the ContentPresenter behaving unexpectedly based on whether the styles are located in the Window.Resources or in a ResourceDictionary. Specifically, I'm setting the Foreground of the default TextBlock to Black, then setting the Foreground value in my default button style to White. If the styles exits on the page like this, they work fine: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero" x:Class="TestBed.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <Style TargetType="{x:Type TextBlock}"> <Setter Property="Foreground" Value="Black" /> </Style> <Style x:Key="ButtonFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1" Margin="2" SnapsToDevicePixels="true"/> </ControlTemplate> </Setter.Value> </Setter> </Style> <LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#F3F3F3" Offset="0"/> <GradientStop Color="#EBEBEB" Offset="0.5"/> <GradientStop Color="#DDDDDD" Offset="0.5"/> <GradientStop Color="#CDCDCD" Offset="1"/> </LinearGradientBrush> <SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/> <Style TargetType="{x:Type Button}"> <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/> <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/> <Setter Property="BorderThickness" Value="1"/> <Setter Property="Foreground" Value="White"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Padding" Value="1"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}"> <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/> </Microsoft_Windows_Themes:ButtonChrome> <ControlTemplate.Triggers> <Trigger Property="IsKeyboardFocused" Value="true"> <Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="ToggleButton.IsChecked" Value="true"> <Setter Property="RenderPressed" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Foreground" Value="#ADADAD"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <StackPanel x:Name="LayoutRoot"> <Button Content="Button" /> </StackPanel> </Window> But if I move those same styles over to a ResourceDictionary, the Foreground of the button switches to black.

Cnoverting application to MVC architecture

Windows Azure: Import/Export Hard Drives, VM ACLs, Web Sockets, Remote Debugging, Continuous Delivery, New Relic, Billing Alerts and More

- by ScottGu

Two weeks ago we released a giant set of improvements to Windows Azure, as well as a significant update of the Windows Azure SDK. This morning we released another massive set of enhancements to Windows Azure. Today’s new capabilities include: Storage: Import/Export Hard Disk Drives to your Storage Accounts HDInsight: General Availability of our Hadoop Service in the cloud Virtual Machines: New VM Gallery, ACL support for VIPs Web Sites: WebSocket and Remote Debugging Support Notification Hubs: Segmented customer push notification support with tag expressions TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services Developer Analytics: New Relic support for Web Sites + Mobile Services Service Bus: Support for partitioned queues and topics Billing: New Billing Alert Service that sends emails notifications when your bill hits a threshold you define All of these improvements are now available to use immediately (note that some features are still in preview). Below are more details about them. Storage: Import/Export Hard Disk Drives to Windows Azure I am excited to announce the preview of our new Windows Azure Import/Export Service! The Windows Azure Import/Export Service enables you to move large amounts of on-premises data into and out of your Windows Azure Storage accounts. It does this by enabling you to securely ship hard disk drives directly to our Windows Azure data centers. Once we receive the drives we’ll automatically transfer the data to or from your Windows Azure Storage account. This enables you to import or export massive amounts of data more quickly and cost effectively (and not be constrained by available network bandwidth). Encrypted Transport Our Import/Export service provides built-in support for BitLocker disk encryption – which enables you to securely encrypt data on the hard drives before you send it, and not have to worry about it being compromised even if the disk is lost/stolen in transit (since the content on the transported hard drives is completely encrypted and you are the only one who has the key to it). The drive preparation tool we are shipping today makes setting up bitlocker encryption on these hard drives easy. How to Import/Export your first Hard Drive of Data You can read our Getting Started Guide to learn more about how to begin using the import/export service. You can create import and export jobs via the Windows Azure Management Portal as well as programmatically using our Server Management APIs. It is really easy to create a new import or export job using the Windows Azure Management Portal. Simply navigate to a Windows Azure storage account, and then click the new Import/Export tab now available within it (note: if you don’t have this tab make sure to sign-up for the Import/Export preview): Then click the “Create Import Job” or “Create Export Job” commands at the bottom of it. This will launch a wizard that easily walks you through the steps required: For more comprehensive information about Import/Export, refer to Windows Azure Storage team blog. You can also send questions and comments to the [email protected] email address. We think you’ll find this new service makes it much easier to move data into and out of Windows Azure, and it will dramatically cut down the network bandwidth required when working on large data migration projects. We hope you like it. HDInsight: 100% Compatible Hadoop Service in the Cloud Last week we announced the general availability release of Windows Azure HDInsight. HDInsight is a 100% compatible Hadoop service that allows you to easily provision and manage Hadoop clusters for big data processing in Windows Azure. This release is now live in production, backed by an enterprise SLA, supported 24x7 by Microsoft Support, and is ready to use for production scenarios. HDInsight allows you to use Apache Hadoop tools, such as Pig and Hive, to process large amounts of data in Windows Azure Blob Storage. Because data is stored in Windows Azure Blob Storage, you can choose to dynamically create Hadoop clusters only when you need them, and then shut them down when they are no longer required (since you pay only for the time the Hadoop cluster instances are running this provides a super cost effective way to use them). You can create Hadoop clusters using either the Windows Azure Management Portal (see below) or using our PowerShell and Cross Platform Command line tools: The import/export hard drive support that came out today is a perfect companion service to use with HDInsight – the combination allows you to easily ingest, process and optionally export a limitless amount of data. We’ve also integrated HDInsight with our Business Intelligence tools, so users can leverage familiar tools like Excel in order to analyze the output of jobs. You can find out more about how to get started with HDInsight here. Virtual Machines: VM Gallery Enhancements Today’s update of Windows Azure brings with it a new Virtual Machine gallery that you can use to create new VMs in the cloud. You can launch the gallery by doing New->Compute->Virtual Machine->From Gallery within the Windows Azure Management Portal: The new Virtual Machine Gallery includes some nice enhancements that make it even easier to use: Search: You can now easily search and filter images using the search box in the top-right of the dialog. For example, simply type “SQL” and we’ll filter to show those images in the gallery that contain that substring. Category Tree-view: Each month we add more built-in VM images to the gallery. You can continue to browse these using the “All” view within the VM Gallery – or now quickly filter them using the category tree-view on the left-hand side of the dialog. For example, by selecting “Oracle” in the tree-view you can now quickly filter to see the official Oracle supplied images. MSDN and Supported checkboxes: With today’s update we are also introducing filters that makes it easy to filter out types of images that you may not be interested in. The first checkbox is MSDN: using this filter you can exclude any image that is not part of the Windows Azure benefits for MSDN subscribers (which have highly discounted pricing - you can learn more about the MSDN pricing here). The second checkbox is Supported: this filter will exclude any image that contains prerelease software, so you can feel confident that the software you choose to deploy is fully supported by Windows Azure and our partners. Sort options: We sort gallery images by what we think customers are most interested in, but sometimes you might want to sort using different views. So we’re providing some additional sort options, like “Newest,” to customize the image list for what suits you best. Pricing information: We now provide additional pricing information about images and options on how to cost effectively run them directly within the VM Gallery. The above improvements make it even easier to use the VM Gallery and quickly create launch and run Virtual Machines in the cloud. Virtual Machines: ACL Support for VIPs A few months ago we exposed the ability to configure Access Control Lists (ACLs) for Virtual Machines using Windows PowerShell cmdlets and our Service Management API. With today’s release, you can now configure VM ACLs using the Windows Azure Management Portal as well. You can now do this by clicking the new Manage ACL command in the Endpoints tab of a virtual machine instance: This will enable you to configure an ordered list of permit and deny rules to scope the traffic that can access your VM’s network endpoints. For example, if you were on a virtual network, you could limit RDP access to a Windows Azure virtual machine to only a few computers attached to your enterprise. Or if you weren’t on a virtual network you could alternatively limit traffic from public IPs that can access your workloads: Here is the default behaviors for ACLs in Windows Azure: By default (i.e. no rules specified), all traffic is permitted. When using only Permit rules, all other traffic is denied. When using only Deny rules, all other traffic is permitted. When there is a combination of Permit and Deny rules, all other traffic is denied. Lastly, remember that configuring endpoints does not automatically configure them within the VM if it also has firewall rules enabled at the OS level. So if you create an endpoint using the Windows Azure Management Portal, Windows PowerShell, or REST API, be sure to also configure your guest VM firewall appropriately as well. Web Sites: Web Sockets Support With today’s release you can now use Web Sockets with Windows Azure Web Sites. This feature enables you to easily integrate real-time communication scenarios within your web based applications, and is available at no extra charge (it even works with the free tier). Higher level programming libraries like SignalR and socket.io are also now supported with it. You can enable Web Sockets support on a web site by navigating to the Configure tab of a Web Site, and by toggling Web Sockets support to “on”: Once Web Sockets is enabled you can start to integrate some really cool scenarios into your web applications. Check out the new SignalR documentation hub on www.asp.net to learn more about some of the awesome scenarios you can do with it. Web Sites: Remote Debugging Support The Windows Azure SDK 2.2 we released two weeks ago introduced remote debugging support for Windows Azure Cloud Services. With today’s Windows Azure release we are extending this remote debugging support to also work with Windows Azure Web Sites. With live, remote debugging support inside of Visual Studio, you are able to have more visibility than ever before into how your code is operating live in Windows Azure. It is now super easy to attach the debugger and quickly see what is going on with your application in the cloud. Remote Debugging of a Windows Azure Web Site using VS 2013 Enabling the remote debugging of a Windows Azure Web Site using VS 2013 is really easy. Start by opening up your web application’s project within Visual Studio. Then navigate to the “Server Explorer” tab within Visual Studio, and click on the deployed web-site you want to debug that is running within Windows Azure using the Windows Azure->Web Sites node in the Server Explorer. Then right-click and choose the “Attach Debugger” option on it: When you do this Visual Studio will remotely attach the debugger to the Web Site running within Windows Azure. The debugger will then stop the web site’s execution when it hits any break points that you have set within your web application’s project inside Visual Studio. For example, below I set a breakpoint on the “ViewBag.Message” assignment statement within the HomeController of the standard ASP.NET MVC project template. When I hit refresh on the “About” page of the web site within the browser, the breakpoint was triggered and I am now able to debug the app remotely using Visual Studio: Note above how we can debug variables (including autos/watchlist/etc), as well as use the Immediate and Command Windows. In the debug session above I used the Immediate Window to explore some of the request object state, as well as to dynamically change the ViewBag.Message property. When we click the the “Continue” button (or press F5) the app will continue execution and the Web Site will render the content back to the browser. This makes it super easy to debug web apps remotely. Tips for Better Debugging To get the best experience while debugging, we recommend publishing your site using the Debug configuration within Visual Studio’s Web Publish dialog. This will ensure that debug symbol information is uploaded to the Web Site which will enable a richer debug experience within Visual Studio. You can find this option on the Web Publish dialog on the Settings tab: When you ultimately deploy/run the application in production we recommend using the “Release” configuration setting – the release configuration is memory optimized and will provide the best production performance.

Notification Hubs: Segmented Push Notification support with tag expressions In August we announced the General Availability of Windows Azure Notification Hubs - a powerful Mobile Push Notifications service that makes it easy to send high volume push notifications with low latency from any mobile app back-end. Notification hubs can be used with any mobile app back-end (including ones built using our Mobile Services capability) and can also be used with back-ends that run in the cloud as well as on-premises. Beginning with the initial release, Notification Hubs allowed developers to send personalized push notifications to both individual users as well as groups of users by interest, by associating their devices with tags representing the logical target of the notification. For example, by registering all devices of customers interested in a favorite MLB team with a corresponding tag, it is possible to broadcast one message to millions of Boston Red Sox fans and another message to millions of St. Louis Cardinals fans with a single API call respectively. New support for using tag expressions to enable advanced customer segmentation With today’s release we are adding support for even more advanced customer targeting. You can now identify customers that you want to send push notifications to by defining rich tag expressions. With tag expressions, you can now not only broadcast notifications to Boston Red Sox fans, but take that segmenting a step farther and reach more granular segments. This opens up a variety of scenarios, for example: Offers based on multiple preferences—e.g. send a game day vegetarian special to users tagged as both a Boston Red Sox fan AND a vegetarian Push content to multiple segments in a single message—e.g. rain delay information only to users who are tagged as either a Boston Red Sox fan OR a St. Louis Cardinal fan Avoid presenting subsets of a segment with irrelevant content—e.g. season ticket availability reminder to users who are tagged as a Boston Red Sox fan but NOT also a season ticket holder To illustrate with code, consider a restaurant chain app that sends an offer related to a Red Sox vs Cardinals game for users in Boston. Devices can be tagged by your app with location tags (e.g. “Loc:Boston”) and interest tags (e.g. “Follows:RedSox”, “Follows:Cardinals”), and then a notification can be sent by your back-end to “(Follows:RedSox || Follows:Cardinals) && Loc:Boston” in order to deliver an offer to all devices in Boston that follow either the RedSox or the Cardinals. This can be done directly in your server backend send logic using the code below: var notification = new WindowsNotification(messagePayload); hub.SendNotificationAsync(notification, "(Follows:RedSox || Follows:Cardinals) && Loc:Boston"); In your expressions you can use all Boolean operators: AND (&&), OR (||), and NOT (!). Some other cool use cases for tag expressions that are now supported include: Social: To “all my group except me” - group:id && !user:id Events: Touchdown event is sent to everybody following either team or any of the players involved in the action: Followteam:A || Followteam:B || followplayer:1 || followplayer:2 … Hours: Send notifications at specific times. E.g. Tag devices with time zone and when it is 12pm in Seattle send to: GMT8 && follows:thaifood Versions and platforms: Send a reminder to people still using your first version for Android - version:1.0 && platform:Android For help on getting started with Notification Hubs, visit the Notification Hub documentation center. Then download the latest NuGet package (or use the Notification Hubs REST APIs directly) to start sending push notifications using tag expressions. They are really powerful and enable a bunch of great new scenarios. TFS & GIT: Continuous Delivery Support for Web Sites + Cloud Services With today’s Windows Azure release we are making it really easy to enable continuous delivery support with Windows Azure and Team Foundation Services. Team Foundation Services is a cloud based offering from Microsoft that provides integrated source control (with both TFS and Git support), build server, test execution, collaboration tools, and agile planning support. It makes it really easy to setup a team project (complete with automated builds and test runners) in the cloud, and it has really rich integration with Visual Studio. With today’s Windows Azure release it is now really easy to enable continuous delivery support with both TFS and Git based repositories hosted using Team Foundation Services. This enables a workflow where when code is checked in, built successfully on an automated build server, and all tests pass on it – I can automatically have the app deployed on Windows Azure with zero manual intervention or work required. The below screen-shots demonstrate how to quickly setup a continuous delivery workflow to Windows Azure with a Git-based ASP.NET MVC project hosted using Team Foundation Services. Enabling Continuous Delivery to Windows Azure with Team Foundation Services The project I’m going to enable continuous delivery with is a simple ASP.NET MVC project whose source code I’m hosting using Team Foundation Services. I did this by creating a “SimpleContinuousDeploymentTest” repository there using Git – and then used the new built-in Git tooling support within Visual Studio 2013 to push the source code to it. Below is a screen-shot of the Git repository hosted within Team Foundation Services: I can access the repository within Visual Studio 2013 and easily make commits with it (as well as branch, merge and do other tasks). Using VS 2013 I can also setup automated builds to take place in the cloud using Team Foundation Services every time someone checks in code to the repository: The cool thing about this is that I don’t have to buy or rent my own build server – Team Foundation Services automatically maintains its own build server farm and can automatically queue up a build for me (for free) every time someone checks in code using the above settings. This build server (and automated testing) support now works with both TFS and Git based source control repositories. Connecting a Team Foundation Services project to Windows Azure Once I have a source repository hosted in Team Foundation Services with Automated Builds and Testing set up, I can then go even further and set it up so that it will be automatically deployed to Windows Azure when a source code commit is made to the repository (assuming the Build + Tests pass). Enabling this is now really easy. To set this up with a Windows Azure Web Site simply use the New->Compute->Web Site->Custom Create command inside the Windows Azure Management Portal. This will create a dialog like below. I gave the web site a name and then made sure the “Publish from source control” checkbox was selected: When we click next we’ll be prompted for the location of the source repository. We’ll select “Team Foundation Services”: Once we do this we’ll be prompted for our Team Foundation Services account that our source repository is hosted under (in this case my TFS account is “scottguthrie”): When we click the “Authorize Now” button we’ll be prompted to give Windows Azure permissions to connect to the Team Foundation Services account. Once we do this we’ll be prompted to pick the source repository we want to connect to. Starting with today’s Windows Azure release you can now connect to both TFS and Git based source repositories. This new support allows me to connect to the “SimpleContinuousDeploymentTest” respository we created earlier: Clicking the finish button will then create the Web Site with the continuous delivery hooks setup with Team Foundation Services. Now every time someone pushes source control to the repository in Team Foundation Services, it will kick off an automated build, run all of the unit tests in the solution , and if they pass the app will be automatically deployed to our Web Site in Windows Azure. You can monitor the history and status of these automated deployments using the Deployments tab within the Web Site: This enables a really slick continuous delivery workflow, and enables you to build and deploy apps in a really nice way. Developer Analytics: New Relic support for Web Sites + Mobile Services With today’s Windows Azure release we are making it really easy to enable Developer Analytics and Monitoring support with both Windows Azure Web Site and Windows Azure Mobile Services. We are partnering with New Relic, who provide a great dev analytics and app performance monitoring offering, to enable this - and we have updated the Windows Azure Management Portal to make it really easy to configure. Enabling New Relic with a Windows Azure Web Site Enabling New Relic support with a Windows Azure Web Site is now really easy. Simply navigate to the Configure tab of a Web Site and scroll down to the “developer analytics” section that is now within it: Clicking the “add-on” button will display some additional UI. If you don’t already have a New Relic subscription, you can click the “view windows azure store” button to obtain a subscription (note: New Relic has a perpetually free tier so you can enable it even without paying anything): Clicking the “view windows azure store” button will launch the integrated Windows Azure Store experience we have within the Windows Azure Management Portal. You can use this to browse from a variety of great add-on services – including New Relic: Select “New Relic” within the dialog above, then click the next button, and you’ll be able to choose which type of New Relic subscription you wish to purchase. For this demo we’ll simply select the “Free Standard Version” – which does not cost anything and can be used forever: Once we’ve signed-up for our New Relic subscription and added it to our Windows Azure account, we can go back to the Web Site’s configuration tab and choose to use the New Relic add-on with our Windows Azure Web Site. We can do this by simply selecting it from the “add-on” dropdown (it is automatically populated within it once we have a New Relic subscription in our account): Clicking the “Save” button will then cause the Windows Azure Management Portal to automatically populate all of the needed New Relic configuration settings to our Web Site: Deploying the New Relic Agent as part of a Web Site The final step to enable developer analytics using New Relic is to add the New Relic runtime agent to our web app. We can do this within Visual Studio by right-clicking on our web project and selecting the “Manage NuGet Packages” context menu: This will bring up the NuGet package manager. You can search for “New Relic” within it to find the New Relic agent. Note that there is both a 32-bit and 64-bit edition of it – make sure to install the version that matches how your Web Site is running within Windows Azure (note: you can configure your Web Site to run in either 32-bit or 64-bit mode using the Web Site’s “Configuration” tab within the Windows Azure Management Portal): Once we install the NuGet package we are all set to go. We’ll simply re-publish the web site again to Windows Azure and New Relic will now automatically start monitoring the application Monitoring a Web Site using New Relic Now that the application has developer analytics support with New Relic enabled, we can launch the New Relic monitoring portal to start monitoring the health of it. We can do this by clicking on the “Add Ons” tab in the left-hand side of the Windows Azure Management Portal. Then select the New Relic add-on we signed-up for within it. The Windows Azure Management Portal will provide some default information about the add-on when we do this. Clicking the “Manage” button in the tray at the bottom will launch a new browser tab and single-sign us into the New Relic monitoring portal associated with our account: When we do this a new browser tab will launch with the New Relic admin tool loaded within it: We can now see insights into how our app is performing – without having to have written a single line of monitoring code. The New Relic service provides a ton of great built-in monitoring features allowing us to quickly see: Performance times (including browser rendering speed) for the overall site and individual pages. You can optionally set alert thresholds to trigger if the speed does not meet a threshold you specify. Information about where in the world your customers are hitting the site from (and how performance varies by region) Details on the latency performance of external services your web apps are using (for example: SQL, Storage, Twitter, etc) Error information including call stack details for exceptions that have occurred at runtime SQL Server profiling information – including which queries executed against your database and what their performance was And a whole bunch more… The cool thing about New Relic is that you don’t need to write monitoring code within your application to get all of the above reports (plus a lot more). The New Relic agent automatically enables the CLR profiler within applications and automatically captures the information necessary to identify these. This makes it super easy to get started and immediately have a rich developer analytics view for your solutions with very little effort. If you haven’t tried New Relic out yet with Windows Azure I recommend you do so – I think you’ll find it helps you build even better cloud applications. Following the above steps will help you get started and deliver you a really good application monitoring solution in only minutes. Service Bus: Support for partitioned queues and topics With today’s release, we are enabling support within Service Bus for partitioned queues and topics. Enabling partitioning enables you to achieve a higher message throughput and better availability from your queues and topics. Higher message throughput is achieved by implementing multiple message brokers for each partitioned queue and topic. The multiple messaging stores will also provide higher availability. You can create a partitioned queue or topic by simply checking the Enable Partitioning option in the custom create wizard for a Queue or Topic: Read this article to learn more about partitioned queues and topics and how to take advantage of them today. Billing: New Billing Alert Service Today’s Windows Azure update enables a new Billing Alert Service Preview that enables you to get proactive email notifications when your Windows Azure bill goes above a certain monetary threshold that you configure. This makes it easier to manage your bill and avoid potential surprises at the end of the month. With the Billing Alert Service Preview, you can now create email alerts to monitor and manage your monetary credits or your current bill total. To set up an alert first sign-up for the free Billing Alert Service Preview. Then visit the account management page, click on a subscription you have setup, and then navigate to the new Alerts tab that is available: The alerts tab allows you to setup email alerts that will be sent automatically once a certain threshold is hit. For example, by clicking the “add alert” button above I can setup a rule to send myself email anytime my Windows Azure bill goes above $100 for the month: The Billing Alert Service will evolve to support additional aspects of your bill as well as support multiple forms of alerts such as SMS. Try out the new Billing Alert Service Preview today and give us feedback. Summary Today’s Windows Azure release enables a ton of great new scenarios, and makes building applications hosted in the cloud even easier. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today. Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S.

Blending the Sketchflow Action

- by GeekAgilistMercenary

Started a new Sketchflow Prototype in Expression Blend recently and documented each of the steps. This blog entry covers some of those steps, which are the basic elements of any prototype. I will have more information regarding design, prototype creation, and the process of the initial phases for development in the future. For now, I hope you enjoy this short walk through. Also, be sure to check out my last quick entry on Sketchflow. I started off with a Sketchflow Project, just like I did in my previous entry (more specifics in that entry about how to manipulate and build out the Sketchflow Map). Once I created the project I setup the following Sketchflow Map. The CoreNavigation is a ComponentScreen setup solely for the page navigation at the top of the screen. The XAML markup in case you want to create a Component Screen with the same design is included below. <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" xmlns:pb="clr-namespace:Microsoft.Expression.Prototyping.Behavior;assembly=Microsoft.Expression.Prototyping.Interactivity" x:Class="RapidPrototypeSketchScreens.CoreNavigation" d:DesignWidth="624" d:DesignHeight="49" Height="49" Width="624"> <Grid x:Name="LayoutRoot"> <TextBlock HorizontalAlignment="Stretch" Margin="307,3,0,0" Style="{StaticResource TitleCenter-Sketch}" Text="Aütøchart Scorecards" TextWrapping="Wrap"> <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonDown"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1"/> </i:EventTrigger> </i:Interaction.Triggers> </TextBlock> <Button HorizontalAlignment="Left" Margin="164,8,0,11" Style="{StaticResource Button-Sketch}" Width="144" Content="Scorecard"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1_2"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> <Button HorizontalAlignment="Left" Margin="8,8,0,11" Style="{StaticResource Button-Sketch}" Width="152" Content="Standard Reports"> <i:Interaction.Triggers> <i:EventTrigger EventName="Click"> <pb:NavigateToScreenAction TargetScreen="RapidPrototypeSketchScreens.Screen_1_1"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> </Grid> </UserControl> Now that the CoreNavigation Component Screen is done I built out each of the others. In each of those screens I included the CoreNavigation Screen (all those little green lines in the image) as the top navigation. In order to do that, as I created each of the pages I would hover over the CoreNavigation Object in the Sketchflow Map. When the utilities drawer (the small menu that pops down under a node when you hover over it) shows click on the third little icon and drag it onto the page node you want a navigation screen on. Once I created all the screens I setup the navigation by opening up each screen and right clicking on the objects that needed to point to somewhere else in the prototype. Once I was done with the main page, my Home Navigation Page, it looked something like this in the Expression Blend Designer. I fleshed out each of the additional screens. Once I was done I wanted to try out the deployment package. The way to deploy a Sketchflow Prototype is to merely click on File –> Package SketchFlow Project and a prompt will appear. In the prompt enter what you want the package to be called. I like to see the files generated afterwards too, so I checked the box to see that. When Expression Blend is done generating everything you’ll have a directory like the one shown below, with all the needed files for deployment. Now these files can be copied or moved to any location for viewing. One can even copy them (such as via FTP) to a server location to share with others. Once they are deployed and you run the "TestPage.html" the other features of the Sketchflow Package are available. In the image below I have tagged a few sections to show the Sketchflow Player Features. To the top left is the navigation, which provides a clearly defined area of movement in a list. To the center right is the actual prototype application. I have placed lists of things and made edits. On the left hand side is the highlight feature, which is available in the Feedback section of the lower left. On the right hand list I underlined the Autochart with an orange marker, and marked out two list items with a red marker. In the lower left hand side in the Feedback section is also an area to type in your feedback. This can be useful for time based feedback, when you post this somewhere and want people to provide subsequent follow up feedback. Overall lots of great features, that enable some fairly rapid prototyping with customers. Once one is familiar with the steps and parts of this Sketchflow Prototype Capabilities it is easy to step through an application without even stopping. It really is that easy. So get hold of Expression Blend 3 and get ramped up on Sketchflow, it will pay off in the design phases to do so! Original Entry
