• What does WIX's CloseApplication functionality do and how would can the application respond to such

  - by tronda

  In the WIX setup I've got, when upgrading the application I have set a requirement to close down applications which might hold on to files which needs to be updated: <util:CloseApplication Id="CloseMyApp" Target="[MyAppExe]" CloseMessage="no" Description="!(loc.MyAppStillRunning)" RebootPrompt="no" ElevatedCloseMessage="no" /> The application on the other hand will capture closing down the window with a "user friendly" dialog box where the user can confirm that he or she wants to close down the application. I've experienced problems with the CloseApplication, and one theory is that the dialog box stops the application from closing. So the question is: Could this be a possible problem? If so - how can I have this confirmation dialog box and still behave properly when the installer asks the application to close down? Must I listen to Win32 messages (such as WM_QUIT/WM_CLOSE) or is there a .NET API which I can use to respond properly to these events?

• Telerik RadWindow does not fire ClientCallBackFunction after a ajax an __DoPostBack

  - by Richard

  HI, I have a Telerik radwindow that allows our users to upload files. When the user first opens the radwindow and sees the upload fields, they can happily select a file and upload it. The window then returns the id of the uploaded file back to the parent page via the ClientCallBackFunction. This function then passes in the ID to a javascript function that calls __DoPostback so that we can populate the list of uploaded files. First time around it works a treat. However all subsequent times it fails to call ClientCallBackFunction unless i refresh the entire page. I also note that any other control on the parent page to uses an ajax postback also stops the ClientCallBackFunction begin called, even on the first time. any ideas? Thanks Richard

• AutoCompleteExtender - authentication failure (forms authentication)

  - by Paddy

  I'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily. If I change my service definition to include a demand for the caller to be authenticated, like so: <OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _ Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?

• SharePoint 2010 FBA with custom form - 403 error

  - by Chris R Chapman

  I have a SharePoint 2010 site that is configured for Forms Based Auth using custom role, membership and profile providers. This works perfectly using the OOTB SharePoint 2010 FBA form (ie. under /_forms in the web app virtual directory). My problem is with a custom login form that is located in a separate folder, /Landing/Login/default.aspx. I've configured the web app to point to this form (contains an unmodified ASP.NET login control), which is rendered when the user hits the root URL. The problem comes when they submit their credentials and the form posts back for the redirection to /_layouts/Authenticate.aspx. It stops cold with a 403. If I revert back to the OOTB FBA form (using the same providers) everything works fine. Any suggestions on what could be going wrong?

• Strategy to lazy load images for buttons within UIScrollView?

  - by greypoint

  I have a horizontal UIScrollView that contains UIButtons (though it could be any object). I would like to only download images for these buttons as the user scrolls and they are seen. I would also like an activityindicator running on each button while the images are downloading. Here's what I've tried with results: Check content offset of uiscrollview and download images for visible buttons. Problem: issues getting activity view shown within subclassed UIButton and not desired usability since images are only downloaded once scrolling stops. Add subviews (not buttons) to the UIScrollview hoping to use the view's ViewController to initiate a downloaded on viewDidAppear. Problem: viewDidAppear never seems to get called (because I am using addSubView?). I've seen other apps that do this kind of loading but need some guidance on the typical set-up. Ebay's app is a great example. All items have a default image until the item comes into view, then an activityindicator runs and the items unique image is downloaded. Thanks for assistance.

• Android TranslateAnimation resets after animation

  - by monmonja

  I'm creating something like a SlideDrawer but with most customization, basically the thing is working but the animation is flickering at the end. To further explain, I got an TranslateAnimation then after this animation it returns back to the original position, if i set setFillAfter then the buttons inside the layout stops working. If i listen to onAnimationEnd and set other's layout to View.GONE the layout fickers. Judging from it is that on animation end, the view goes back to original position before the View.GONE is called. Any advice would be awesome. Thanks

• jQuery UI sortable('cancel') - this.helper is null

  - by Kerry

  I am trying to disable a sortable element from sorting when it has been double clicked. When I try to disable it, even without a condition, it gives me the error 'this.helper is null'. $('.roundedBox:first', division).sortable({ start: function( event, ui ) { if( true === true ) { $(this).sortable('cancel'); } $(this).parent().data( 'sorting', true ); }, stop: function() { $(this).parent().data( 'sorting', false ); }, items: '.department', update: function() {}, placeholder: 'department-placeholder' }) Any ideas on how I can do this? I don't need it to be this method. Literally anything thing that stops it will work. The problem is, sorting starts on a single click, but I have another action bound to double click. If it's double clicked, I don't want it to drag.

  - by Hakim

  Hi All Hope someone can help me on this, on the old OS version 3.0 and down , hitting the done button one playing a Video would automatically dismiss the view, but now since we have to control the view appearance, hitting the Done just stops the movie but does not dismiss the view, I tried to check if it was linked to any notification and found that each time the Done button was hit, MPMoviePlayerPlaybackStateDidChangeNotification is triggered the problem is that the same notification is received for any change of state pausing /playing... so dismissing the view when MPMoviePlayerPlaybackStateDidChangeNotification is triggered is not an option. does anyone have an answer for this problem Thx for your help

• iphone setting UITextView delegate breaks auto completion

  - by Tristan

  Hi there! I have a UITextField that I would like to enable auto completion on by: [self.textView setAutocorrectionType:UITextAutocorrectionTypeYes]; This works normally, except when I give the UITextView a delegate. When a delegate is set, auto complete just stops working. The delegate has only the following method: - (void)textViewDidChange:(UITextView *)textView { self.textView.text = [self.textView.text stringByReplacingOccurrencesOfString:@"\n" withString:@""]; int left = LENGTH_MAX -[self.textView.text length]; self.characterCountLabel.text = [NSString stringWithFormat:@"%i",abs(left)]; } Does anyone know how to have both auto complete enabled and a delegate set? Thanks!Tristan

• How can I resolve exception: Error executing child request for ChartImg.axd

  - by macleojw

  I'm using the Chart Controls for Mircosoft .NET Framerwork. Most of the time they work perfectly. However, if I leave a page for longer than 20-30 mins and then try to refresh the page, I get an error saying: Error executing child request for ChartImg.axd. Exception Details: System.Web.HttpException: Error executing child request for ChartImg.axd. If I update the page using an AJAX update panel I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd It seems that the chart handler stops after a period of inactivity. Most of the webpages I've looked at for this error are for situations when this error is displayed all the time. In my case it is only displayed after a period of inactivity. Can someone provide a better explanation of what is happening and suggest a solution?

• Random "Not Found" error with Silverlight accessing ASP.NET Web Services

  - by user245822

  I'm developing an application with Silverlight 3 and ASP.NET Web Services, which uses Linq to SQL to get data from my SQL Server database. Randomly when the user causes an action to get information from any of my web service methods, Silverlight throws the exception "The remote server returned an error: NotFound.", of type "CommunicationException", with the InnerException status of "System.Net.WebExceptionStatus.UnknownError". Almost 10% of requests gets this error. If the user tries to get the same information again, normally the request has no erros and the user gets the data. When debugging in Visual Studio only Silverlight stops on the exception, and I see no reason for the web service not being found.

  I want to add my own session variable to elmah error log table and display it. I already have modified the source code and added the new fields to Error.cs and other fields but I don't know but when I assign an HttpContext.Current.Session["MyVar"].tostring() value to my field in the constructor it stops logging exceptions and does not log any exception. I just need to get the value of the session variable is there other way for this. I read a post which he added fields for the email but it does not say where exactly should I get the session value.

• Passing variable to Google Charts URL

  - by Rob A

  Hi All, This is probably something really simple, however I am quite new to PHP, and havent done any HTML in years. I need to get a PHP variable filled with an array of figures into Google Charts. My code for this so far is: <img src="http://chart.apis.google.com/chart? &chs=340x175 &chd=t:<?=$filedetail[1]?> &cht=lc &chtt=Test "> However, Google reports an error, as it stops at the ?=$filedetail[1] for some reason. It doesnt seem that reading the variable is the problem, more that the API simply cant read past the start of the PHP tags. Thanks, Rob A.

• Accessing original WordPress blog's DB from sub-blogs in network mode

  - by aendrew

  I'm helping with a university radio station website that runs WordPress and was recently switched over to Network (Multi-site/multi-user) mode by myself. The setup is as such: The parent site (www.stationID.com) runs a bunch of custom-built plugins to construct things like the show schedule calendar, the "Now Playing" widget, podcast list, et cetera. The new network websites ("wiki.stationID.com", "buddypress.stationID.com" for instance) run the same template as the parent site, but it stops after rendering the first section because the widgets from point 1 grab data from the main site's database that is not available to sub-blogs. My question is: how do I get data from the main site's tables on the sub-domain sub-blogs? A related question is: how do I set the $wpdb->prefix to be the same as the parent site on the child websites without it negatively effecting how the child website pulls data from its own database? Any help would be awesome, thanks!

• Bug Running Android Tutorial HelloTabWidget under SDK 1.5: "setCurrentTag(getIntent())"

  - by Matt J.

  does not compile. Indeed: even in 1.5, this api, getIntent(), is already listed as deprecated. The error message I get complains that getIntent() does not return a String, but setCurrentTab() expects a string. If I guess and change the line to read: "tabHost.setCurrentTab(1); // was setCurrentTab(getIntent())", then it compiles, builds, but does not run. I get the "stopped unexpectedly" error message from the emulator. I cannot even get Log.d to output, so it seems that it stops 'unexpectedly' very early. So the first and main question is: what is the correct fix to "tabHost.setCurrentTab(getIntent())" in the final line of OnCreate() in http://developer.android.com/resources/tutorials/views/hello-tabwidget.html? The second and simpler question is: did I guess right in replacing 'mTabHost' with tabHost in the one place where that occurs?

• Android compatibility with Restlet/JSON/Jackson

  - by Cookie

  Hi there, I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at the first of those commands. Wireshark shows a tcp exchange, the server gets the requests. There is no exceptions or anything. Something in the serialization/deserialization semms not to work. I'm using the newest version of Jackson libraries (1.5.3) and the restlet jar in the android edition. Is there any known problems with Jackson and Android? Which code and libraries are compatible with Android? Thanks in advance.

• Visualizing Undirected Graph That's Too Large for GraphViz?

  - by Gabe

  Hi Everyone, I was wondering if anyone has any advice for rendering an undirected graph with 178,000 nodes and 500,000 edges. I've tried Neato, Tulip, and Cytoscape. Neato doesn't even come remotely close, and Tulip and Cytoscape claim they can handle it but don't seem to be able to. (Tulip does nothing and Cytoscape claims to be working, and then just stops.) Does anyone have any ideas? I'd just like a vector format file (ps or pdf) with a remotely reasonable layout of the nodes. Thanks!

• InvokeMember("click") webBrowser help

  - by Tom

  I am trying to automate a web page via the weBrowser and the button that i'm trying to click has no ID only a value. here's the html code for it: Accept I can't useGetElementById as the button has no ID. If I do HtmlElement goButton = this.webBrowser1.Document.All["Accept"]; goButton.InvokeMember("click"); My script stops showing a nullreference error highlighting the "goButton.InvokeMember("click");" If I do var inputControls = (from HtmlElement element in webBrowser1.Document.GetElementsByTagName("input") select element).ToList(); HtmlElement submitButton = inputControls.First(x = x.Name == "Accept"); My script give me an "Sequence contains no matching element" error at the "HtmlElement submitButton" line and sometimes the page has more than one of these Accept buttons, so I would need to be able to tell the difference between each one as well or at least be able to click on one without the script breaking Any help with this will be greatly appreciated

• Silverlight Listbox firing MouseRightButtonDown, but not MouseLeftButtonDown

  - by Steav

  I have this problem in a bigger Project...... so I set up a 'Testpoject' as Proof of Concept: New Silverlight-Application Add Listbox Fill listbox with a few Checkboxes Register listBox1_MouseLeftButtonDown register listBox1_MouseRightButtonDown You will see, that the listBox1_MouseLeftButtonDown won't fire under any circumstances.... listBox1_MouseRightButtonDown however fires just fine. I tried using a custom Class deriving from ListBox and overriding, assuming something in the ListBox Class was setting e.Handled = false, but this did not change the behaviour, either. Any Ideas on why this happens and how to fix? (This problem also stops the 'parent'-control from receiving the Click-Event... so the Event-passing is broke)

• Android: Ringer mode changed to silent doesn't stop the phone vibrating

  - by Flo

  I'm trying to change the ringer mode of the phone to RINGER_MODE_SILENT when a call is incoming by using the following lines of code. AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); am.setRingerMode(AudioManager.RINGER_MODE_SILENT); While the phone stops ringing it continue to vibrate although the documentation of RINGER_MODE_SILENT says it should also stop vibrating. I'm using the SDK 1.6 UPDATE: As I didn't find a solution yet, I tried to deactivate the vibration settings manually. am.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_ONLY_SILENT ); But this also doesn't prevent the phone form vibrating when a call is incoming. Any ideas?

• Listening to the iPhone mic with SCListener and playing music at the same time: how?

  - by Eamon Ford

  Hello, I am using Stephen Celis' SCListener class (for iPhone) to "listen" from the microphone, but I also need to be playing music at the same time using the MediaPlayer framework. However, when I start listening with SCListener, the music fades out and stops. I have set the kAudioSessionCategory_PlayAndRecord property on the audio session in SCListener, which should allow me to play audio and record audio at the same time, but as far as I can tell it has no effect. I'm confused, because according to other developers' results, this works just fine, but not for me. I'm thinking maybe the kAudioSessionCategory_PlayAndRecord property allows you to play sound and record if you're using the AVAudioPlayer framework or something to play the sound, but maybe not the MediaPlayer framework? This would be a problem for me because I need to play music from the user's iPod library, which, as far as I know is only possible to do using the MediaPlayer framework. Does anyone know how I can get around this problem? Thanks in advance!

  I'm trying to implement hxxp://www.cssstickyfooter.com however I am having a few problems! See screenshot: hxxp://img22.imageshack.us/img22/2654/71161106.jpg The div "Content" contains both left and right columns. On smaller resolutions this is working as expected however once the user starts to increase there resolution the content doesn't expand as I intend it to. If you notice the blue box. That should stretch to the footer at the bottom of the page. If you notice that the blue divider line (right_container3-4) stops also at the same point. CODE HTML: hxxp://tinyurl.com/m39x52 CSS: hxxp://tinyurl.com/lb62ej I would apriciate any help at all! I've been racking my brains for ages on this one, its just a small site so I suppose it's not too much of an issue. But it's nice to know all the same! Thankyou P.S. Sorry about the URL formatting

• how to run an ActiveX that must be visible and topmost on a server without a desktop?

  - by DanJ

  We're writing a server application that needs to use an ActiveX object that must be visible and Top-Most otherwise it doesn't render correctly. The challenge is that servers typically don't have an active desktop, and therefore the applications should not require one. Ours does. I must use this ActiveX, and I don't have access to the source code. When running from within remote-desktop everything works fine as long as the session is open. As soon as the session closes it stops working. I'm guessing this is because there is no desktop. Any ideas how I can work this out in a secure and robust way?
