  • How can I create a hybrid Silverlight and aspx application

    - by PilotBob
    Here is my scenerio.. We have an ASP.Net 2.x web site. We want to migrate it to Silverlight full frame application. However, there is no way we can go away in a corner and redo every web page in SL right off the bat. What I would like to do is build the chrome of the app (main page, dashboard, login, common system/config screens, main menu) in SL and be able to open existing .aspx pages in the main content SL frame. From what I see there is no way to do this. I thought the Webbrowser control in SL4 would be the answer, but apparently that only works if your app is run out of browser. So, what is my best recourse? It seems like I will have to create some type of .aspx page that hosts the .XAP and pass in the page I want it to load? How would you gurus approach this?

  • Cocoa Memory Usage

    - by user288024
    I'm trying to track down some peculiar memory behavior in my Cocoa desktop app. My app does a lot of image processing using NSImage and uploads those images to a website over HTTP using NSURLConnection. After uploading several hundred images (some very large), when I run Instrument I get no leaks. I've also run through MallocDebug and get no leaks. When I dig into object allocations using Instrument I get output like this: GeneralBlock-9437184, Net Bytes 9437184, # Net 1 GeneralBlock-192512, Net Bytes 2695168, # Net 14 and etc., for smaller sizes. When I look at these in detail, they're marked as being owned by 'Foundation' and created via NSConcreteMutableData initWithCapacity. During HTTP upload I'm creating a post body using NSMutableData, so I'm guessing these are buffers Cocoa is caching for me when I create the NSMutableData objects. Is there a way to force Cocoa to free these? I'm 90% positive I'm releasing correctly (and Instruments and MallocDebug seem to confirm this), but I think Cocoa is keeping these around for perf reasons since I'm allocating so many MSMutableData buffers.

    Hi, I am trying to write a small app to connect and manipulate some data on an SQL 2008 Express database. The database is on my local machine but I can see it on the network.

I tried using Windows Auth and also tried SQL Server Auth with no luck. Can someone please assist me? What am I missing?

  • Deploying Django at Dreamhost

    - by Imran
    I'm trying to get the Poll tutorial working at my Dreamhost account (I don't have any prior experience of deploying Django).

  • Using Knockout.js to bind bootstrap daterange picker and parse span contents

    - by jmkr
    I'm new to knockout and trying to get what should be a simple task up and running. I'm working on an MVC4 .NET app with the intention of binding a date range picker to make ajax requests for updating Highchart graph data. I'm using Dan Grossman's bootstrap-themed date picker and it's been great so far (https://github.com/dangrossman/bootstrap-daterangepicker). The basic goal is to watch the span that this jQuery date ranger picker updates, and then use knockout to pass this value to another part of the app for the ajax request. I've tried everything I can find online.. valueUpdate:change on the span to using some jQuery within knockout to get the same goal done, to using a subscribe function to watch the value of the span before and after the date picker is used. Apparently this uses the jQuery .change() event handler, which is only good on inputs, selects, and textareas.. not spans. Here's the fiddle of what I have so far: http://jsfiddle.net/eyygK/9/ Appreciate any help and input.

    I am trying to use mod_rewrite to pretty up a URL. I want the URL to look like this: http://example.com/bart/school?page=2 and the rewritten URL to be: http://localhost:8080/app?user=bart&tag1=school&page=2 If possible, I would also like to be able to have more than one tag per user: http://example.com/bart/school/lisa?page=2 Would look like: http://localhost:8080/app?user=bart&tag1=school&tag2=lisa&page=2 I far as I can tell this is possible by using mod_rewrite but I can't seem to figure it out. Any help would be really appreciated!

  • What iPhone OS APIs could I use to implement a transition animation similar to the iBook page flip t

    - by Dr Dork
    I'm building an iPad app that will have multiple paper pages and I'd like to implement a page transition affect that is similar to the animation you see when you turn pages in the iBooks app on the iPad. A few questions... Is that animation readily available somewhere in the UIKit API or would I have to implement it myself? If I have to implement it myself, what's a good approach or API I should look into? It definitely has a 3d feel to it, could they be using the OpenGL ES API for that? Thanks in advance for all your help, I'm going to start researching these questions right now.

  • jqmodal IE (7 or 8) flashes black before modal loaded

    - by brad
    This is killing me. In both IE7 and 8, using jqModal, the screen flashes black before the modal content is loaded. I've set up a test app to show you what's happening. I've taken jqModal EXACTLY from the site, no changes whatsoever, no external css that could be affecting my app. It works perfectly in every other browser (including IE6). http://jqmtest.heroku.com/ So, first two links are ajax calls, second is straight up inline HTML. (I originally thought it was the ajax that was affecting it, but that doesn't seem to be the case, I then thought it was slow loading ajax, hence to two differen ajax links) What's crazy is that the jqmodal site itself works perfectly in IE, no flashing of black, but I can't see what I'm doing wrong. Code is straight forward html: <body> <div id="ajaxModal" class="jqmWindow"></div> <div id="inlineModal" class="jqmWindow"> <div style="height:300px;position:relative;"> <p>Here's some inline content</p> <a href="#" onclick='$("#inlineModal").jqmHide();return false;' style="position:absolute;bottom:10px;right:10px">Close</a> </div> </div> <div style="width:600px;height:400px;margin:auto;background:#eee;"> <p><a href="/ajax/short" class="jqModal">Short loading modal</a></p> <br /> <p><a href="/ajax/long" class="jqModal">Longer loading modal</a></p> <br /> <p><a href="#" class="jqInline">inline modal</a></p> </div> </body> Javascript: <script type="text/javascript"> $(function(){ $("#ajaxModal").jqm({ajax:'@href', modal:true}); $("#inlineModal").jqm({modal:true, trigger:'.jqInline'}); }); </script> CSS is exactly the same as the one downloaded from jqModal's site so I'll omit it, but you can see it on my app Has anyone experienced this? I don't get how his works and mine doesn't.

  • Detect Installed Application URI Handler on Webkit browsers

    - by Punit Raizada
    Guys, I have a question mainly related to the Iphone web browser but I am hoping the same solution would work on other browsers that are webkit based. I have a application (Iphone + Android) that registers a handler for custom URI (appuri://) on the Phone. I am able to launch the application by making a link to "appuri://act/launch" from my web pages. This works only if my application is installed on the device. If the device does not have the app installed then a message comes up "Safari was not able to open ....". What I want to do is detect if the URI Scheme is supported from the browser and then prompt my own message saying "please download the app ..blah blah blah" if the handler for the URI scheme is not found. Is there a way I can detect or find the list of URL Scheme handlers on the Phone from the Web Browser ?

  • Extending Code Igniter Model functions to external PHP Scripts

    - by Fábio Antunes
    Hello everybody. I'm doing a small web app, which uses CKeditor for user input, and CKfinder for file management (images/flash). Those who know CKFinder, also know that the config file for CKFinder as a function named CheckAuthentication() that returns false or true, giving or not permissions to use CKFinder. This is were a Custom PHP Code checks if the user as authorization to access CKFinder or not. Well for my app I'm using Code Igniter, and of course I've created a model were i handle everything about User Permissions, Loggin, Session Cookies, etc. And i also have a function witch its propose is just to check if the user is Logged in. So I would like to know if someone knows a way that i can call the function isLoggedIn() inside the model security from inside the function CheckAuthentication() in CKFinder config file. Thanks in advance.

  • Problem with Twitter basic authentication using AJAX

    - by jelford
    I'm developing a javascript App that needs, as part of its functionality, for users to be able to update their Twitter status. The App is designed to work on mobiles, and as such I don't really want to be sending users all the way over to the Twitter site to sign in; they should just be able to pass their credentials to the app, and I'll handle all the signin. So I'm trying to use the Basic Auth with the restful API. My code looks like: function postTweet(input){ $.ajax( { type: "POST", url: "http://twitter.com/statuses/update.json", data: {status: input}, dataType: "json", error: function() { alert("Some error occured"); }, success: function() { alert("Success!"); }, beforeSend: function(request) { request.setRequestHeader("Authorization", "Basic BASE64OFMYCREDENTIALS");} } ) ; } So, as far as I'm aware, this should perform the authentication from the XMLHttpRequest header, and then post the status. However, whenever I call this code, I get a "401 Unauthorized" error from Twitter. Below are the request & response headers from firebug: Request: OPTIONS /statuses/update.json HTTP/1.1 Host: twitter.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Origin: null Access-Control-Request-Method: POST Access-Control-Request-Headers: authorization Response: HTTP/1.1 401 Unauthorized Date: Sat, 13 Mar 2010 11:08:58 GMT Server: hi Status: 401 Unauthorized WWW-Authenticate: Basic realm="Twitter API" X-Runtime: 0.00204 Content-Type: application/json; charset=utf-8 Cache-Control: no-cache, max-age=300 Set-Cookie: guest_id=1268478538488; path=/ _twitter_sess=BAh7CDoPY3JlYXRlZF9hdGwrCPlyNlcnAToHaWQiJWUyN2YzYjc3OTk2NGQ3%250ANzJkYTA4MjYzOWJmYTQyYmUyIgpmbGFzaElDOidBY3Rpb25Db250cm9sbGVy%250AOjpGbGFzaDo6Rmxhc2hIYXNoewAGOgpAdXNlZHsA--d687808459872da0aa6a89cab35fd347300b4d07; domain=.twitter.com; path=/ Expires: Sat, 13 Mar 2010 11:13:58 GMT Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 88 Connection: close Any help with this would be much appreciated, Thanks, jelford ps.

  • Toolbar items in sub-nib

    - by roe
    This question has probably been asked before, but my google-fu must be inferior to everybody else's, cause I can't figure this out. I'm playing around with the iPhone SDK, and I'm building a concept app I've been thinking about. If we have a look at the skeleton generated with a navigation based app, the MainWindow.xib contains a navigation controller, and within that a root-view controller (and a navigation bar and toolbar if you play around with it a little). The root-view controller has the RootViewController-nib associated with it, which loads the table-view. So far so good. To add content to the tool bar and to the navigation bar, I'm supposed to add those to in the hierarchy below the Root View Controller (which works, no problem). However, what I can't figure out is, this is all still within the MainWindow.xib (or, at runtime, nib). How would I define a xib in order for it to pick up tool bar items from that? I want to do (the equivalent of, just reusing the name here) RootViewController *controller = [[RootViewController alloc] initWithNibName:nil bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; and have the navigation controller pick-up on the tool bar items defined in that nib. The logical place to put it would be in the hierarchy under File's Owner (which is of type RootViewController), but it doesn't appear to be possible. Currently, I'm assigning these (navigationItem and toolbarItems) manually in the viewDidLoad method, or define them in the MainWindow.xib directly to be loaded when the app initializes. Any ideas? Edit I guess I'll try to explain with a picture. This is the Interface Builder of the main window, pretty much as it comes out of the wizard to create a navigation based project. I've added a toolbar item for clarity though. You can see the navigation controller, with a toolbar and a navigation bar, and the root view controller. Basically, the Root View Controller has a bar button item and a navigation item as you can see. The thing is, it's also got a nib associated with it, which, when loaded will instantiate a view, and assign it to the view outlet of the controller (which in that nib is File's Owner, of type RootViewController, as should be). How can I get the toolbar item, and the navigation item, into the other nib, the RootViewController.nib so I can remove them here. The RootViewController.nib adds everything else to the Root View Controller, why not these items? The background for this is that I want to simply instantiate RootViewController, initialize it with its own nib (i.e. initWithNibName:nil shown above), and push it onto the navigation controller, without having to add the navigation/toolbar items in coding (as I do it now).

  • Java 1.4 to Java 6 migration

    - by joesatch
    Hi, I have some enterprise apps running on Java 1.4. They mostly invoke Stored Proces on DB, Parse XML files (Not too large files, at the most few megs), read/write from/to disk. We have a requirement where now we have to migrate these apps to Java 6(No code changes to be done at all). My questions: If I dont recompile my apps under Java 6 and just run them with it, will it work fine (I know they 'should'). But if somebody thinks other way round, could you kindly share your thoughts please? More important question is - Will it have any perfomance impact?. As in, App compiled on 1.4 and running on 1.6 vs App compiled and running on 1.6. Is 1.6 gonna do any bytecode optimization for the same old peace of code compared to 1.4? Many Thanks js

  • Adding rows to UItableview and passing data between Viewcontrollers

    - by Jonathan
    I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

  • Visual Studio / Visual Source Safe / Integrated Security / IIS 7

    - by Jason
    Using Visual Source Safe with IIS integration (the working dir is the IIS site) Visual Studio, pointed to the IIS site would load up the Web project. It would be under VSS control (have to check out files, etc). Recently, we had to switch to Integrated Security for our database connections from the web app. This means changing the impersonation of the IIS app pool (and anon authentication) to the impersonated account. Since I did this -- my project loads in Visual Studio, but it acts as if I'm not me, and the files aren't under source control anymore. I'm going to assume it's something with the pass-through from IIS to the VSS (as if you'll remember you had to add IIS_USERS to the VSS list of users). Even trying to add the impersonated account didn't work. Any ideas?

  • Reverse engineering to get answers

    - by cornjuliox
    So I've spent the last few days looking for a way to create a simple image drawing app with wxPython, and I think the key to doing just that is understanding how to use Device Contexts. The problem is that the wxPython demo program doesn't demonstrate DCs, and the docs for both wxPython and wxWidgets don't explain as much as I'd like to know so I've decided to try and 'reverse engineer' an existing app to see how its done. The first problem I have is that I don't know of any drawing apps written in wxPython (or any written in Python for that matter o.o), and the second is I don't know how I'd go about doing it. Am I right in saying that I'm going to need a copy of an application's Python source and something like Winpdb? What do professional programmers do when they find themselves in a situation like mine, needing answers that the docs don't provide?

  • copy HTML to UIPasteboard

    - by ManniAT
    Hi, I want to transfer HTML from my app to the iPhone mail application. I already have the HTML text - lest say <span style='color:red'Test</span I can place this to UIPasteBoard - but when I paste it to mail I get the html source. When I place the same string in a HTMLView - select it there and copy it it pastes as red text in mail. What do I have to do to place the string in the UIPasteBoard so that it pastes as red text to the mail application? I've been searching for "format types" - and found that UIPasteBoard returns "Aplle Web Archive pasteboard type" when I have the element (copied from UIWebView) in the clipboard. But setting this as type when adding the content to UIPasteBoard pastes nothing in the mail app. Manfred

  • Print Preview Control used in a custom Print Preview Dialog.

    - by Kildareflare
    I have successfully implemented printing and print preview for my app using the PrintDocument, PrintDialog and PrintPreviewDialog classes of .NET. However my app uses a toolkit to improve the appearance of the standard .NET controls. There are versions of most .NET controls in the toolkit, but none for the Print controls. Therefore to ensure that the appearance of these controls matches the rest of the app I am creating a custom PrintPreviewDialog based on a toolkit form and embedding a .NET PrintPrewviewControl in it. My problem is that the PrintPreviewControl always shows "No pages to display". I had no trouble getting this to work using the .NET PrintPreviewDialog and cannot see what I am doing wrong. This is a .NET 2.0 PrintPreviewControl and so I know that I need to call InvalidatePreview() after assigning the PrintDocument. However it does not seem to matter where i place it, the PrintPage event handler never gets called... EDIT: I've just noticed that while the original PrintDocument m_printDocument shows a PrintPageHandler in its properties, the m_printPreviewControl.Document does not. Any ideas why it is being lost..? public class PrintEngine { ...rest of class... public PrintEngine() { m_printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage); } public void PrintPreview() { //ORIGINAL CODE USING .NET DIALOG WORK OK //PrintPreviewDialog dlg1 = new PrintPreviewDialog(); //dlg1.Document = m_printDoc; //PrepareImageForPrinting(); //dlg1.ShowDialog(); //CODE USING MY CUSTOM DIALOG DO NOT WORK? MyPrintPreviewDialog dlg2 = new MyPrintPreviewDialog(); dlg2.Document = m_printDoc; PrepareImageForPrinting(); //Creates the m_printImage List dlg2.ShowDialog(); } private void printDoc_PrintPage(object sender, PrintPageEventArgs e) { e.Graphics.DrawImage(m_printImages[m_currentPage], new Point(0, 0)); m_currentPage++; e.HasMorePages = m_currentPage < m_pagesHigh; } }//end PrintEngine class public class MyPrintPreviewDialog : KryptonForm { public PrintDocument Document { get { return m_printPreviewControl.Document; } set { m_printPreviewControl.Document = value; m_printPreviewControl.InvalidatePreview(); } } public MyPrintPreviewDialog() { InitializeComponent(); m_printPreviewControl = new PrintPreviewControl(); m_printPreviewControl.StartPage = 0; } private void MyPrintPreviewDialog_Load(object sender, EventArgs e) { m_printPreviewControl.Document.DefaultPageSettings = new PageSettings(); m_printPreviewControl.Document.PrinterSettings = new PrinterSettings(); m_printPreviewControl.InvalidatePreview(); } }//end MyPrintPreviewDialog class

Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77%5FCommands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine.

  • How do you include additional files using VS2010 web deployment packages?

    - by Jason
    I am testing out using the new web packaging functionality in visual studio 2010 and came across a situation where I use a pre-build event to copy required .dll's into my bin folder that my app relies on for API calls. They cannot be included as a reference since they are not COM dlls that can be used with interop. When I build my deployment package those files are excluded when I choose the option to only include the files required to run the app. Is there a way to configure the deployment settings to include these files? I have had no luck finding any good documentation on this.

  • Get-WMIObject fails when run AsJob

    - by codepoke
    It's a simple question, but it's stumped me. $cred = Get-Credential $jobs = @() $jobs += Get-WmiObject ` -Authentication 6 ` -ComputerName 'serverName' ` -Query 'Select * From IISWebServerSetting' ` -Namespace 'root/microsoftiisv2' ` -EnableAllPrivileges ` -Credential $cred ` -Impersonation 4 ` -AsJob $joblist = Wait-Job -Job $jobs -Timeout 60 foreach ($job in $jobs) { if ($job.State -eq "Completed") { $app = Receive-Job -Job $job $app } else { ("Job not completed: " + $job.Name + "@" + $job.State + ". Reason:" + $job.ChildJobs[0].JobStateInfo.Reason) Remove-Job -Job $job -Force } } The query succeeds when run directly and fails when run -AsJob. Reason:System.UnauthorizedAccessException: Access is denied. I've jiggered with -Impersonation, -Credentials, -Authority, and -EnableAllPrivileges to no useful effect. It appears I'm overlooking something fundamental. Why is my Powershell prompt allowed to connect to the remote server, but my child process denied?

  • Aaron Hillegass Chapter 18 Challenge Question

    - by jasonbogd
    I am working through Aaron Hillegass' Cocoa Programming for Mac OS X and am doing the challenge for Chapter 18. Basically, the challenge is to write an app that can draw ovals using your mouse, and then additionally, add saving/loading and undo support. I'm trying to think of a good class design for this app that follows MVC. Here's what I had in mind: Have a NSView-subclass that represents an oval (say JBOval) that I can use to easily draw an oval. Have a main view (JBDrawingView) that holds JBOvals and draws them. The thing is that I wasn't sure how to add archiving. Should I archive each JBOval? I think this would work, but archiving an NSView doesn't seem very efficient. Any ideas on a better class design? Thanks.
