• When will EBS 12.2 be released?

  - by Steven Chan (Oracle Development)

  The most frequently asked question at OpenWorld this year was, "When will EBS 12.2 be released?" Sadly, Oracle's communication policies prohibit us from speculating about release dates for unreleased software. We are not permitted to give estimates, rough timelines, guesses, or anything else that remotely resembles specific guidance on release dates. You can monitor My Oracle Support and this blog for updates on EBS 12.2.  I'll post them here as soon as they're available.  I'm embedding an old favourite from 2007 in its entirety here, since it applies equally to new releases as well as certifications. "Loose Lips Sink Ships" (March 20, 2007)If I were to sort emails in my inbox into groups, the biggest -- by far -- would be the one for emails that start with, "When will _____ be certified with the E-Business Suite?"  I answer these dutifully but know that my replies can sometimes be maddening, for two reasons:  technical uncertainty, and Oracle's rules for such communications. On the Spiral Model of CertificationsTechnology stack certifications tend to be highly iterative in nature.  As a result, statements about certification dates tend to be accurate only when made in hindsight.  Laypeople are horrified to hear this, but it's the ugly truth.  Uncertainty is simply inherent to the process.  I've become inured to it over the years, but it might come as a surprise to you that it can take many cycles to get fully-released software to work together.  Take this scenario: We test a particular combination of Component A and B. If we encounter a problem, say, with Component A, we log a bug. We receive a new version of Component A. The process iterates again. The reality is this: until a certification is completed and released, there's no accurate way of telling how many iterations are yet to come.  This is true regardless of the number of iterations that have already been completed.  Our Lips Are SealedGenerally, people understand that things are subject to change, so the second reason I can't say anything specific is actually much more important than the first.  "Loose lips might sink ships" was coined in World War II in an effort to remind people that careless talk can have serious consequences.  Curiously, this applies to Oracle's communications about upcoming features, configurations, and releases, too.  As a publicly traded company, we have very strict policies that prohibit us from linking specific releases to specific dates.  If you've ever listened to an earnings call with analysts, you'll often hear them asking, "Can you add a little more color to that statement?"  For certifications, color is usually the only thing that I have.  Sometimes I can provide a bit more information about the technical nature of the certification in question, such as expected footprints or version levels.  I can occasionally share technical issues that we've found, too, to convey the degree of risk or complexity involved in the certification.  Aside from that, there's little additional information about specific dates, date ranges, or even speculation about dates that I can provide... that is, without having one of those uncomfortable conversations with Oracle Legal.  So, as much as it pains me to do so, when it comes to dates, I'm always forced to conclude with a generic reply that blandly states one of the following: We're working on that certification right now That certification is in the pipeline but hasn't been started yet We don't have plans for that certification Don't Shoot the MessengerThankfully, I've developed a thick skin over the years -- which is a good thing, considering the colorful and energetic responses I've received over the years after answering these questions.  However, on behalf of my Oracle colleagues who are faced with these questions every day in the field, I urge you to remember that they're required to follow these same corporate rules about date disclosures.  It never hurts to ask, but don't be too disappointed if we can't provide you with a detailed answer.  The Go-Go's had it right, after all.  Related Articles Webcast Replay Available: Technical Preview of EBS 12.2 Online Patching

• Problem with sprite direction and rotation

  - by user2236165

  I have a sprite called Tool that moves with a speed represented as a float and in a direction represented as a Vector2. When I click the mouse on the screen the sprite change its direction and starts to move towards the mouseclick. In addition to that I rotate the sprite so that it is facing in the direction it is heading. However, when I add a camera that is suppose to follow the sprite so that the sprite is always centered on the screen, the sprite won't move in the given direction and the rotation isn't accurate anymore. This only happens when I add the Camera.View in the spriteBatch.Begin(). I was hoping anyone could maybe shed a light on what I am missing in my code, that would be highly appreciated. Here is the camera class i use: public class Camera { private const float zoomUpperLimit = 1.5f; private const float zoomLowerLimit = 0.1f; private float _zoom; private Vector2 _pos; private int ViewportWidth, ViewportHeight; #region Properties public float Zoom { get { return _zoom; } set { _zoom = value; if (_zoom < zoomLowerLimit) _zoom = zoomLowerLimit; if (_zoom > zoomUpperLimit) _zoom = zoomUpperLimit; } } public Rectangle Viewport { get { int width = (int)((ViewportWidth / _zoom)); int height = (int)((ViewportHeight / _zoom)); return new Rectangle((int)(_pos.X - width / 2), (int)(_pos.Y - height / 2), width, height); } } public void Move(Vector2 amount) { _pos += amount; } public Vector2 Position { get { return _pos; } set { _pos = value; } } public Matrix View { get { return Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) * Matrix.CreateScale(new Vector3(Zoom, Zoom, 1)) * Matrix.CreateTranslation(new Vector3(ViewportWidth * 0.5f, ViewportHeight * 0.5f, 0)); } } #endregion public Camera(Viewport viewport, float initialZoom) { _zoom = initialZoom; _pos = Vector2.Zero; ViewportWidth = viewport.Width; ViewportHeight = viewport.Height; } } And here is my Update and Draw-method: protected override void Update (GameTime gameTime) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; TouchCollection touchCollection = TouchPanel.GetState (); foreach (TouchLocation tl in touchCollection) { if (tl.State == TouchLocationState.Pressed || tl.State == TouchLocationState.Moved) { //direction the tool shall move towards direction = touchCollection [0].Position - toolPos; if (direction != Vector2.Zero) { direction.Normalize (); } //change the direction the tool is moving and find the rotationangle the texture must rotate to point in given direction toolPos += (direction * speed * elapsed); RotationAngle = (float)Math.Atan2 (direction.Y, direction.X); } } if (direction != Vector2.Zero) { direction.Normalize (); } //move tool in given direction toolPos += (direction * speed * elapsed); //change cameracentre to the tools position Camera.Position = toolPos; base.Update (gameTime); } protected override void Draw (GameTime gameTime) { graphics.GraphicsDevice.Clear (Color.Blue); spriteBatch.Begin (SpriteSortMode.BackToFront, BlendState.AlphaBlend, null, null, null, null, Camera.View); spriteBatch.Draw (tool, new Vector2 (toolPos.X, toolPos.Y), null, Color.White, RotationAngle, originOfToolTexture, 1, SpriteEffects.None, 1); spriteBatch.End (); base.Draw (gameTime); }

• XNA WP7 Texture memory and ContentManager

  - by jlongstreet

  I'm trying to get my WP7 XNA game's memory under control and under the 90MB limit for submission. One target I identified was UI textures, especially fullscreen ones, that would never get unloaded. So I moved UI texture loads to their own ContentManager so I can unload them. However, this doesn't seem to affect the value of Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage"), so it doesn't look like the memory is actually being released. Example: splash screens. In Game.LoadContent(): Application.Instance.SetContentManager("UI"); // set the current content manager for (int i = 0; i < mSplashTextures.Length; ++i) { // load the splash textures mSplashTextures[i] = Application.Instance.Content.Load<Texture2D>(msSplashTextureNames[i]); } // set the content manager back to the global one Application.Instance.SetContentManager("Global"); When the initial load is done and the title screen starts, I do: Application.Instance.GetContentManager("UI").Unload(); The three textures take about 6.5 MB of memory. Before unloading the UI ContentManager, I see that ApplicationCurrentMemoryUsage is at 34.29 MB. After unloading the ContentManager (and doing a full GC.Collect()), it's still at 34.29 MB. But after that, I load another fullscreen texture (for the title screen background) and memory usage still doesn't change. Could it be keeping the memory for these textures allocated and reusing it? edit: very simple test: protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); PrintMemUsage("Before texture load: "); // TODO: use this.Content to load your game content here red = this.Content.Load<Texture2D>("Untitled"); PrintMemUsage("After texture load: "); } private void PrintMemUsage(string tag) { Debug.WriteLine(tag + Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage")); } protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here if (count++ == 100) { GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("Before CM unload: "); this.Content.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After CM unload: "); red = null; spriteBatch.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After SpriteBatch Dispose(): "); } base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here if (red != null) { spriteBatch.Begin(); spriteBatch.Draw(red, new Vector2(0,0), Color.White); spriteBatch.End(); } base.Draw(gameTime); } This prints something like (it changes every time): Before texture load: 7532544 After texture load: 10727424 Before CM unload: 9875456 After CM unload: 9953280 After SpriteBatch Dispose(): 9953280

• Create Custom Speech Bubbles in Silverlight.

  - by mbcrump

  I had a reader email me the following question: “How do you create Speech Bubbles in Silverlight/WPF without adding any extra .dlls? Right off the bat, I know at least two ways to create the speech bubbles that look just like the ones in comic books. Using the Callout Shapes included with Blend 4. Using the free 3rd party control named FreeBubbles (I used this before Blend 4). Unfortunately, we cannot use either of these as they will both add extra .dll’s to the project. So why wouldn’t you want to use one of those? I can think of a few reasons: You do not want to increase the size of your .XAP by including extra .dll’s. You do not have Expression Blend or the license to the use the .dll’s. You want a custom Speech Bubble that is not included in the four “Callout” Controls with Blend. Instead of using one of these methods, we will create a Speech Bubble in Blend 4 using Path element and a TextBlock. Before we get started, lets look at the Callout Shapes included with Blend 4. Using Blend 4 you can simply drag/drop these controls onto your Silverlight application and you are ready to go. We can create all of these Speech Bubbles and even some of the modern bubbles used in recent comic books. Lets get started. Start up Expression Blend 4 and select the Pen Tool. On the Art Board, start connecting the dots like I did below. You can add a color if you wish. …keep going …complete Let’s go ahead and add some text to the Speech Bubble. Drag a TextBlock from the Panel and put it directly inside the Speech Bubble. Go ahead and set the TextAlignment to Center for the TextBlock. and give it some text. At this point, you could go ahead and create a user control if you want to reuse the Speech Bubble you created. Select both the Path and the TextBlock by clicking then while holding down CTRL and then Right Click them. Select Make Into User Control. Give it a name and then Build your project. Lets create another one using the Ellipse for the older comic book style of Speech Bubbles. Drag an Ellipse to the Artboard and give it a color. Now, grab the Pen and drag a triangle like I did below. Simply drag it over a corner of the Ellipse. Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. Lets go ahead and create a rounded rectangle one by adding a Rectangle to the Artboard. Go ahead and set the RadiuX and RadiusY to 25 to give it rounded edges. Let’s create another path and drag it right on top of our rounded rectangle like we did earlier. …looking good Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. So let’s look at what we’ve created today using the path element and TextBlock. As you can tell, it required more work but meets the requirements. This was actually fun to do and I encourage anyone that visits my blog to send in request like this.  Subscribe to my feed

• Spring boot JAR as windows service

  - by roblovelock

  I am trying to wrap a spring boot "uber JAR" with procrun. Running the following works as expected: java -jar my.jar I need my spring boot jar to automatically start on windows boot. The nicest solution for this would be to run the jar as a service (same as a standalone tomcat). When I try to run this I am getting "Commons Daemon procrun failed with exit value: 3" Looking at the spring-boot source it looks as if it uses a custom classloader: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-tools/spring-boot-loader/src/main/java/org/springframework/boot/loader/JarLauncher.java I also get a "ClassNotFoundException" when trying to run my main method directly. java -cp my.jar my.MainClass Is there a method I can use to run my main method in a spring boot jar (not via JarLauncher)? Has anyone successfully integrated spring-boot with procrun? I am aware of http://wrapper.tanukisoftware.com/. However due to their licence I can't use it. UPDATE I have now managed to start the service using procrun. set SERVICE_NAME=MyService set BASE_DIR=C:\MyService\Path set PR_INSTALL=%BASE_DIR%prunsrv.exe REM Service log configuration set PR_LOGPREFIX=%SERVICE_NAME% set PR_LOGPATH=%BASE_DIR% set PR_STDOUTPUT=%BASE_DIR%stdout.txt set PR_STDERROR=%BASE_DIR%stderr.txt set PR_LOGLEVEL=Error REM Path to java installation set PR_JVM=auto set PR_CLASSPATH=%BASE_DIR%%SERVICE_NAME%.jar REM Startup configuration set PR_STARTUP=auto set PR_STARTIMAGE=c:\Program Files\Java\jre7\bin\java.exe set PR_STARTMODE=exe set PR_STARTPARAMS=-jar#%PR_CLASSPATH% REM Shutdown configuration set PR_STOPMODE=java set PR_STOPCLASS=TODO set PR_STOPMETHOD=stop REM JVM configuration set PR_JVMMS=64 set PR_JVMMX=256 REM Install service %PR_INSTALL% //IS//%SERVICE_NAME% I now just need to workout how to stop the service. I am thinking of doing someting with the spring-boot actuator shutdown JMX Bean. What happens when I stop the service at the moment is; windows fails to stop the service (but marks it as stopped), the service is still running (I can browse to localhost), There is no mention of the process in task manager (Not very good! unless I am being blind).

• Ext JS Tab Panel - Dynamic Tabs - Tab Exists Not Working

  - by Joey Ezekiel

  Hi Would appreciate if somebody could help me on this. I have a Tree Panel whose nodes when clicked load a tab into a tab panel. The tabs are loading alright, but my problem is duplication. I need to check if a tab exists before adding it to the tab panel. I cant seem to have this resolved and it is eating my brains. This is pretty simple and I have checked stackoverflow and the EXT JS Forums for solutions but they dont seem to work for me or I'm being blind. This is my code for the tree: var opstree = new Ext.tree.TreePanel({ renderTo: 'opstree', border:false, width: 250, height: 'auto', useArrows: false, animate: true, autoScroll: true, dataUrl: 'libs/tree-data.json', root: { nodeType: 'async', text: 'Tool Actions' }, listeners: { render: function() { this.getRootNode().expand(); } } }) opstree.on('click', function(n){ var sn = this.selModel.selNode || {}; // selNode is null on initial selection renderPage(n.id); }); function renderPage(tabId) { var TabPanel = Ext.getCmp('content-tab-panel'); var tab = TabPanel.getItem(tabId); //Ext.MessageBox.alert('TabGet',tab); if(tab){ TabPanel.setActiveTab(tabId); } else{ TabPanel.add({ title: tabId, html: 'Tab Body ' + (tabId) + '', closable:true }).show(); TabPanel.doLayout(); } } }); and this is the code for the Tab Panel new Ext.TabPanel({ id:'content-tab-panel', region: 'center', deferredRender: false, enableTabScroll:true, activeTab: 0, items: [{ contentEl: 'about', title: 'About the Billing Ops Application', closable: true, autoScroll: true, margins: '0 0 0 0' },{ contentEl: 'welcomescreen', title: 'PBRT Application Home', closable: false, autoScroll: true, margins: '0 0 0 0' }] }) Can somebody please help?

• Trigger event on click except for checkbox + label

  - by Jamaica Bob

  I have a table row, which triggers an event when clicked. There are (not displayed) checkbox + its styled label inside the row. What i want is to prevent (i guess with :not or .not() but cant figure it out) the execution if checkbox/label is clicked. HTML: <center> <table> <tr class='pend'> <td><input type="checkbox" id="bb"/> <label for="bb">X</label></td> <td>&nbsp;</td> <td>some text</td> </tr> </table> </center> CSS: center { margin-top:20px; } input[type=checkbox] + label { width:10px; height:10px; background-color:red; } input[type=checkbox] { display:none; } table tr { height:40px; background-color:gray; } table td { padding:5px; } JS: $('.pend').on('click',function(){ $(this).append('text'); return false; }) JSFIDDLE: http://jsfiddle.net/ySuGB/2/

• Paragraph formatting in a WPF RichTextBox?

  - by David Veeneman

  I need to apply paragraph formatting to a selection in a rich text box. My RTB will behave the same way as the rich text boxes on StackOverflow--the user can type text into the RTB, but they can also enter code blocks. The RTB will apply very simple formatting to the code block--it will change the font and apply a background color to the entire block, similar to what you see in the code block below. Changing the font is pretty straightforward: var textRange = new TextRange(rtb.Selection.Start, rtb.Selection.End); textRange.ApplyPropertyValue(TextElement.FontFamilyProperty, "Consolas"); textRange.ApplyPropertyValue(TextElement.FontSizeProperty, 10D ); Now I need to apply some paragraph-level formatting. I need to set the paragraph margin to 0, so I don't get a blank line between code lines, and I need to set the paragraph background color. Here's my problem: I can't figure out how to get the paragraph elements from the selection, so that I can apply formatting. Any suggestions? An example of how to apply the Margin and Background properties would be incredibly helpful. Thanks!

• jquery Ui Dialog box opacity / alpha filter broken in IE7/8 when using jquery.effects.fade.js

  - by Ideasman101

  Greetings! Goal: transparant ui dialog box in IE7/8 with fade in/out effect upon open/close. Opacity was set in css and works just fine (safari, chrome, ff ie7/8) using native effects blind / explode etc. But when using efects.fade.js on the dialog box the opacity does not work on ie7/8 We want fade in/out because that looks awesome. Anyway here is my code. Any help much appreciated. Maybe something to do with filter or cleartype. My css .ui-dialog { position: absolute; padding: .2em; width: 300px; overflow: hidden; opacity:0.85;filter:alpha(opacity=85);} My jQuery // Dialog1 $('#dialog1').dialog({ position: [250,120], autoOpen: false, closeOnEscape: true, modal: false, show: { effect: "fade", options: {}, speed: 1500 }, hide: { effect: "fade", options: {}, speed: 1500 }, resizable: false, width: 350, height: 200 }); // Dialog Link 1 $('#dialog_link1').click(function(){ $([1,2,3]).each(function(){ var num = this; $('#dialog'+num).dialog('close'); }); $('#dialog1').dialog('open'); $('body').css("background-image", "url(images/image1.jpg)"); $('body').css("background-repeat", "no-repeat"); $('body').css("background-position", "bottom center"); $('body').css("background-attachment", "fixed"); $('body').css("bottom", "0px"); return false; });

• Rendering a UIWebView in drawRect with loadHTMLString

  - by Nick Weaver

  Hello there, I am having a problem with UIWebView. I'd like to render my own html code in it. When I add a webview as a subview and put in some html code it renders just fine. When it gets down to some optimized drawing of tableview cell with the drawRect method the problem pops up. Drawing UIView descendants works pretty well this way. It's even possible to load a URL with the loadRequest method, setting the delegate, conforming to the UIWebViewDelegate protocol and redrawing the table cell with setNeedsDisplay when webViewDidFinishLoad is called. It does show, but when it comes to loadHTMLString, nothing shows up, only a white rect. Due to performance reasons I have to do the drawing in the drawRect method. Any ideas? Thanks in advance Nick Example snippet code for the html code being loaded by a UIWebView: NSString *html = @"<html><head><title>My fancy webview</title></head><body style='background-color:green;'><p>It somehow seems<h2 style='color:black;'>this does not show up in drawRect</h2>!</p></body></html>"; [webView loadHTMLString:html baseURL:nil]; Snippet for the drawRect method: - (void)drawRect:(CGRect)aRect { CGContextRef context = UIGraphicsGetCurrentContext(); [[webView layer] renderInContext:context]; }

• Greyscale Image from YUV420p data

  - by fergs

  From what I have read on the internet the Y value is the luminance value and can be used to create a grey scale image. The following link: http://www.bobpowell.net/grayscale.htm, has some C# code on working out the luminance of a bitmap image : { Bitmap bm = new Bitmap(source.Width,source.Height); for(int y=0;y<bm.Height;y++) public Bitmap ConvertToGrayscale(Bitmap source) { for(int x=0;x<bm.Width;x++) { Color c=source.GetPixel(x,y); int luma = (int)(c.R*0.3 + c.G*0.59+ c.B*0.11); bm.SetPixel(x,y,Color.FromArgb(luma,luma,luma)); } } return bm; } I have a method that returns the YUV values and have the Y data in a byte array. I have the current piece of code and it is failing on Marshal.Copy – attempted to read or write protected memory. public Bitmap ConvertToGrayscale2(byte[] yuvData, int width, int height) { Bitmap bmp; IntPtr blue = IntPtr.Zero; int inputOffSet = 0; long[] pixels = new long[width * height]; try { for (int y = 0; y < height; y++) { int outputOffSet = y * width; for (int x = 0; x < width; x++) { int grey = yuvData[inputOffSet + x] & 0xff; unchecked { pixels[outputOffSet + x] = UINT_Constant | (grey * INT_Constant); } } inputOffSet += width; } blue = Marshal.AllocCoTaskMem(pixels.Length); Marshal.Copy(pixels, 0, blue, pixels.Length); // fails here : Attempted to read or write protected memory bmp = new Bitmap(width, height, width, PixelFormat.Format24bppRgb, blue); } catch (Exception) { throw; } finally { if (blue != IntPtr.Zero) { Marshal.FreeHGlobal(blue); blue = IntPtr.Zero; } } return bmp; } Any help would be appreciated?

• Sending formatted Lotus Notes rich text email from Excel VBA

  - by Lunatik

  I have little Lotus Script or Notes/Domino knowledge but I have a procedure, copied from somewhere a long time ago, that allows me to email through Notes from VBA. I normally only use this for internal notifications where the formatting hasn't really mattered. I now want to use this to send external emails to a client, and corporate types would rather the email complied with our style guide (a sans-serif typeface basically). I was about to tell them that the code only works with plain text, but then I noticed that the routine does reference some sort of CREATERICHTEXTITEM object. Does this mean I could apply some sort of formatting to the body text string after it has been passed to the mail routine? As well as upholding our precious brand values, this would be quite handy to me for highlighting certain passages in the email. I've had a dig about the 'net to see if this code could be adapted, but being unfamiliar with Notes' object model, and the fact that online Notes resources seem to mirror the application's own obtuseness, meant I didn't get very far. The code: Sub sendEmail(EmailSubject As String, EMailSendTo As String, EMailBody As String, MailServer as String) Dim objNotesSession As Object Dim objNotesMailFile As Object Dim objNotesDocument As Object Dim objNotesField As Object Dim sendmail As Boolean 'added for integration into reporting tool Dim dbString As String dbString = "mail\" & Application.UserName & ".nsf" On Error GoTo SendMailError 'Establish Connection to Notes Set objNotesSession = CreateObject("Notes.NotesSession") On Error Resume Next 'Establish Connection to Mail File Set objNotesMailFile = objNotesSession.GETDATABASE(MailServer, dbString) 'Open Mail objNotesMailFile.OPENMAIL On Error GoTo 0 'Create New Memo Set objNotesDocument = objNotesMailFile.createdocument Dim oWorkSpace As Object, oUIdoc As Object Set oWorkSpace = CreateObject("Notes.NotesUIWorkspace") Set oUIdoc = oWorkSpace.CurrentDocument 'Create 'Subject Field' Set objNotesField = objNotesDocument.APPENDITEMVALUE("Subject", EmailSubject) 'Create 'Send To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("SendTo", EMailSendTo) 'Create 'Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("CopyTo", EMailCCTo) 'Create 'Blind Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("BlindCopyTo", EMailBCCTo) 'Create 'Body' of memo Set objNotesField = objNotesDocument.CREATERICHTEXTITEM("Body") With objNotesField .APPENDTEXT emailBody .ADDNEWLINE 1 End With 'Send the e-mail Call objNotesDocument.Save(True, False, False) objNotesDocument.SaveMessageOnSend = True 'objNotesDocument.Save objNotesDocument.Send (0) 'Release storage Set objNotesSession = Nothing Set objNotesMailFile = Nothing Set objNotesDocument = Nothing Set objNotesField = Nothing 'Set return code sendmail = True Exit Sub SendMailError: Dim Msg Msg = "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & Chr(13) & Err.Description MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext sendmail = False End Sub

• WPF TreeViewItem Context Menu Unhighlights Item

  - by Snea

  I have been having problems with this for some time now, and have come up with some less-than-desirable solutions. The problem is that when a TreeViewItem's context menu is opened, the TreeViewItem is greyed out. Is it possible for a TreeViewItem to stay highlighted while its ContextMenu is open? The problem with the TreeViewItem greying out, is that it gives no relation to the context menu and the TreeViewItem, and it looks ugly. Generally, the code I use for setting a context menu is this. Sometimes the context menu will be generated by the code with a PreviewRightMouseButtonDown EventSetter, but it doesn't make a difference. <TreeView> <TreeView.Resources> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="Menu Item 1" /> <MenuItem Header="Menu Item 2" /> </ContextMenu> </Setter.Value> </Setter> </Style> </TreeView.Resources> <TreeViewItem Header="Item 1"> <TreeViewItem Header="Sub-Item 1"/> </TreeViewItem> <TreeViewItem Header="Item 2"></TreeViewItem> </TreeView> So far the only solution I have found is to override the "grey" unfocused color with the focused color, but then the TreeView never seems unfocused, such as when another control is clicked on. I have had problems with ListViews as well.

• Flex 3 - Style not applying completely on dynamically created tabs in TabNavigator

  - by user254177

  When I create a tab dynamically via ActionScript, the style for the newly created (and selected) tab get applied to the skins, but not the text, unless I click on another tab and then click back to it. This is the A/S, MXML and CSS code I am using: private function clickAddTabHandler(event:Event):void{ var vbox:VBox = new VBox; var tab:Canvas = new (Canvas); vbox.label = "Select Location"; vbox.addChild(tab); tabBar.addChild(vbox); tabBar.selectedIndex = tabBar.numChildren-1; } .tabNavigator { disabledSkin: Embed(source="assets/skins/TabBar-tab_disabledSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); downSkin: Embed(source="assets/skins/TabBar-tab_downSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); overSkin: Embed(source="assets/skins/TabBar-tab_overSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); upSkin: Embed(source="assets/skins/TabBar-tab_upSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); selectedDisabledSkin: Embed(source="assets/skins/TabBar-tab_selectedDisabledSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); selectedUpSkin: Embed(source="assets/skins/TabBar-tab_selectedUpSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); selectedOverSkin: Embed(source="assets/skins/TabBar-tab_selectedUpSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); selectedDownSkin: Embed(source="assets/skins/TabBar-tab_selectedUpSkin.png", scaleGridTop=1, scaleGridLeft=20, scaleGridBottom=18, scaleGridRight=32); textAlign: left; paddingLeft: 20; paddingRight: 20; fontSize: 11; fontFamily: Helvetica Neue; color: #FFFFFF; textRollOverColor: #FFFFFF; } .tabNavigatorSelected { textAlign: left; paddingLeft: 20; paddingRight: 20; fontSize: 11; fontFamily: Helvetica Neue; color: #135F9E; textRollOverColor: #135F9E; textSelectedColor: #135F9E; }

Example: <Style TargetType="ToggleButton" x:Key="toggleCollapsed"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate TargetType="ToggleButton"> <Border Background="#00FFFFFF" Width="19" Height="13" > <Border BorderThickness="1,1,1,1" CornerRadius="1,1,1,1" BorderBrush="#FF8E997D" Width="9" Height="9" > <Border.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="1,1"> <LinearGradientBrush.GradientStops> <GradientStop Color="#FFFFFFFF" Offset="0.4" /> <GradientStop Color="#FFC3BAAA" Offset="1" /> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.Background> <Path Data="M0,2L0,3 2,3 2,5 3,5 3,3 5,3 5,2 3,2 3,0 2,0 2,2z" x:Name="pathToggle" Fill="#FF000000" Margin="1,1,1,1"/> </Border> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> The style above is stored in my .resx. I want to convert it back to style

• How to update a QPixmap in a QGraphicsView with PyQt

  - by pops

  I am trying to paint on a QPixmap inside a QGraphicsView. The painting works fine, but the QGraphicsView doesn't update it. Here is some working code: #!/usr/bin/env python from PyQt4 import QtCore from PyQt4 import QtGui class Canvas(QtGui.QPixmap): """ Canvas for drawing""" def __init__(self, parent=None): QtGui.QPixmap.__init__(self, 64, 64) self.parent = parent self.imH = 64 self.imW = 64 self.fill(QtGui.QColor(0, 255, 255)) self.color = QtGui.QColor(0, 0, 0) def paintEvent(self, point=False): if point: p = QtGui.QPainter(self) p.setPen(QtGui.QPen(self.color, 1, QtCore.Qt.SolidLine)) p.drawPoints(point) def clic(self, mouseX, mouseY): self.paintEvent(QtCore.QPoint(mouseX, mouseY)) class GraphWidget(QtGui.QGraphicsView): """ Display, zoom, pan...""" def __init__(self): QtGui.QGraphicsView.__init__(self) self.im = Canvas(self) self.imH = self.im.height() self.imW = self.im.width() self.zoomN = 1 self.scene = QtGui.QGraphicsScene(self) self.scene.setItemIndexMethod(QtGui.QGraphicsScene.NoIndex) self.scene.setSceneRect(0, 0, self.imW, self.imH) self.scene.addPixmap(self.im) self.setScene(self.scene) self.setTransformationAnchor(QtGui.QGraphicsView.AnchorUnderMouse) self.setResizeAnchor(QtGui.QGraphicsView.AnchorViewCenter) self.setMinimumSize(400, 400) self.setWindowTitle("pix") def mousePressEvent(self, event): if event.buttons() == QtCore.Qt.LeftButton: pos = self.mapToScene(event.pos()) self.im.clic(pos.x(), pos.y()) #~ self.scene.update(0,0,64,64) #~ self.updateScene([QtCore.QRectF(0,0,64,64)]) self.scene.addPixmap(self.im) print('items') print(self.scene.items()) else: return QtGui.QGraphicsView.mousePressEvent(self, event) def wheelEvent(self, event): if event.delta() > 0: self.scaleView(2) elif event.delta() < 0: self.scaleView(0.5) def scaleView(self, factor): n = self.zoomN * factor if n < 1 or n > 16: return self.zoomN = n self.scale(factor, factor) if __name__ == '__main__': import sys app = QtGui.QApplication(sys.argv) widget = GraphWidget() widget.show() sys.exit(app.exec_()) The mousePressEvent does some painting on the QPixmap. But the only solution I have found to update the display is to make a new instance (which is not a good solution). How do I just update it?

• CSS positioning inside div

  - by christian

  I am using a div with 2 elements inside and I want to position my 1st element to be vertically aligned top and 2nd element to the bottom of the div. The div is the right portion of my page and equal to the height of my main content. #right { float:right; width: 19%; background:#FF3300; margin-left:2px; padding-bottom: 100%; margin-bottom: -100%; } #right .top { display:block; background-color:#CCCCCC; } #right .bottom { bottom:0px; display:block; background-color:#FFCCFF; height:60px; } HTML: <div id="right"> <span class="top">Top element</span> <span class="bottom"><img src="images/logo_footer1.gif" width="57" height="57" align="left" class="img">&nbsp;<img src="images/logo_footer2.gif" width="57" height="57" align="right" class="img"></span> </div> I want the right div to be like this:

• Positioning Layers and text gradients with css

  - by Kenji Crosland

  I'm a CSS newbie trying to get some text gradients going on. I tried this code here but it didn't work for me, most likely because the h1 object is nested within a #header div. I imagine there's something to do with layers that I don't know about. Either I get a gradent block that is in front of everything or it's not appearing at all. In this particular instance this code makes a big gradient bar appear in front of everything: #header { clear:both; float:left; -moz-background-inline-policy:continuous; -moz-background-origin:padding; background:#080E73 url(../images/header-background.png) repeat-x left 0px; width:100%; max-height: 175px; color: #080E73; } #header h1 { margin-bottom: 0; color: #000; position: relative; } #header h1 span { background:url(../images/headline-text.png) repeat-x; display: block; width: 100%; height: 100%; position: absolute; } Here is the HTML (I'm using ruby on rails hence the notation) <div id="header"> <% unless flash[:notice].blank? %> <div id="notice"><%= flash[:notice] %></div> <% end %> <%= image_tag ("header-image.png") %> <h1><span></span>Headline</h1> <strong>Byline</strong> ... #navbar html... </div> I tried playing with z-index but I couldn't come up with any good results. Any ideas?

• Populating Models from other Models in Django?

  - by JT

  This is somewhat related to the question posed in this question but I'm trying to do this with an abstract base class. For the purposes of this example lets use these models: class Comic(models.Model): name = models.CharField(max_length=20) desc = models.CharField(max_length=100) volume = models.IntegerField() ... <50 other things that make up a Comic> class Meta: abstract = True class InkedComic(Comic): lines = models.IntegerField() class ColoredComic(Comic): colored = models.BooleanField(default=False) In the view lets say we get a reference to an InkedComic id since the tracer, err I mean, inker is done drawing the lines and it's time to add color. Once the view has added all the color we want to save a ColoredComic to the db. Obviously we could do inked = InkedComic.object.get(pk=ink_id) colored = ColoredComic() colored.name = inked.name etc, etc. But really it'd be nice to do: colored = ColoredComic(inked_comic=inked) colored.colored = True colored.save() I tried to do class ColoredComic(Comic): colored = models.BooleanField(default=False) def __init__(self, inked_comic = False, *args, **kwargs): super(ColoredComic, self).__init__(*args, **kwargs) if inked_comic: self.__dict__.update(inked_comic.__dict__) self.__dict__.update({'id': None}) # Remove pk field value but it turns out the ColoredComic.objects.get(pk=1) call sticks the pk into the inked_comic keyword, which is obviously not intended. (and actually results in a int does not have a dict exception) My brain is fried at this point, am I missing something obvious, or is there a better way to do this?

• Why is this simple jQuery hover event misbehaving in Internet Explorer 8?

  - by Siracuse

  I asked for help earlier on Stackoverflow involving highlighting spans with the same Class when a mouse hovers over any Span with that same Class. It is working great: http://stackoverflow.com/questions/2709686/how-can-i-add-a-border-to-all-the-elements-that-share-a-class-when-the-mouse-has $('span[class]').hover( function() { $('.' + $(this).attr('class')).css('background-color','green'); }, function() { $('.' + $(this).attr('class')).css('background-color','yellow'); } ) Here is an example of it in usage: http://dl.dropbox.com/u/638285/0utput.html However, it doesn't appear to work properly in IE8, while it DOES work in Chrome/Firefox. Here is a screenshot of it in IE8, with my mouse hovered over the " min) { min" section in the middle. As you can see, it highlighted the span that the mouse is hovering over perfectly fine. However, it has also highlighted some random spans above and below it that don't have the same class! Only the span's with the same Class as the one where the mouse is over should be highlighted green. In this screenshot, only that middle green section should be green. Here is a screenshot of it working properly in Firefox/Chrome with my mouse in the exact same position: This screenshot is correct as the span that the mouse is over (the green section) is the only one in this section that shares that class. Why is IE8 randomly green-highlighting spans when it shouldn't be (they don't share the same class) using my little jQuery snippet? Again, if you want to see it live I have it here: http://dl.dropbox.com/u/638285/0utput.html

• iPhone SDK : UIImageView - Collapsing animation

  - by chris.o.

  Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

• CSS sliding door background image problem.

  - by ethyreal

  I noticed I am not the first to ask about CSS sliding doors. However this seems (at least to me) to be a rather odd problem which I have not seen an answer for. Trying to create a simple rounded corner link button: html: <a href="#" class="link_button"><span>Add A New Somthing</span></a> css: .link_button { background: transparent url('img/backgrounds/bg-buttonRight.png') no-repeat scroll top right; color: #444; display: block; float: left; font: normal 12px arial; height: 41px; margin-right: 6px; padding-right: 14px; text-decoration: none; } .link_button span { background: transparent url('img/backgrounds/bg-buttonLeft.png') no-repeat top left; display: block; line-height: 31px; padding: 5px 0 5px 14px; } .link_button:active { background-position: bottom right; color: #000; outline: none; } .link_button:active span { background-position: bottom left; padding: 6px 0 4px 18px; } results: The two images are overlapping, which is what I want, but why the discoloration? Why would one be darker? I tried using png jpg, gif, with and without transparency. I posted the code here, along with another attempt using only one jpg instead of two, but still the same results. Did I miss something? Thanks in advance.

• Tips on creating user interfaces and optimizing the user experience

  - by Saif Bechan

  I am currently working on a project where a lot of user interaction is going to take place. There is also a commercial side as people can buy certain items and services. In my opinion a good blend of user interface, speed and security is essential for these types of websites. It is fairly easy to use ajax and JavaScript nowadays to do almost everything, as there are a lot of libraries available such as jQuery and others. But this can have some performance and incompatibility issues. This can lead to users just going to the next website. The overall look of the website is important too. Where to place certain buttons, where to place certain types of articles such as faq and support. Where and how to display error messages so that the user sees them but are not bothering him. And an overall color scheme is important too. The basic question is: How to create an interface that triggers a user to buy/use your services I know psychology also plays a huge role in how users interact with your website. The color scheme for example is important. When the colors are irritating on a website you just want to click away. I have not found any articles that explain those concept. Does anyone have any tips and/or recourses where i can get some articles that guide you in making the correct choices for your website.

• How did the Lunar Lander example make the image backgrounds transparent?

  - by user279112

  Hello. I'm trying to make a GUI program with the Android SDK, using their Lunar Lander example as a significant self-teaching tool in the process. I've noticed their sprites' images' backgrounds, which were at least usually pure white, did not show up in their program. I want to ask how they did that, since their site doesn't explain simple things very well. I've managed to pull that off before on another GUI SDK, wherein all I had to do was to call a function and pass it a few floats to define a certain color, and until my code told it to do otherwise, that function would make sure that that particular color in my sprites' images was totally transparent. However I've wrestled with the Lunar Lander example and getting my own program to show some custom graphics for a week or two now, and I haven't noticed any such function call in the Lunar Lander example. I tried to look for it, but I did not find anything. I've tried to Google some tutorial or other reference material, but what I've found so far is just straying off into unrelated areas and totally dodging this EXTREMELY important lesson on the SDK's basics. Any ideas? Thanks!
