• Windows Forms VS2005 MyApplication_Shutdown not getting fired.

  We are developing windows application in VS2005 (VB.Net). I have placed resource clearing and audit entry in the "MyApplication_Shutdown" event. But this event is not getting fired when our application exits. When I tired with the sample application, in our system it works fine. I don't know whether I have disabled any setting so that this event does get fired. Note: I have checked application framework checkbox in application settings. Looking at the WindowsFormsApplicationBase class, the Shutdown event is fired right after Application.Run() exits. Not seeing this event means that Application.Run() doesn't exit normally. The only thing I can come up with: an unhandled exception. Do you trap the UnhandledException event ...Show All

• Visual Basic Online help doesn't prompt for Proxy Authentication

  Hi, If I want to access external web pages through my company's LAN then I have to go through a proxy and that proxy prompts me for authentication before I can continue. This is true for any application accessing the internet including IE, Windows Media Player and RealOne Player. However, not for Visual Studio 2005 Express Online Help it seems! When trying to access online help, instead of being prompted for my internet username and password, I get the following error: 'Search Failed The request failed with HTTP status 407: Proxy Authentication Required.' Why can't the help system prompt me for the authentication details as other applications do Is there a work around for this Thanks Oli I just encountered t ...Show All

• Windows Search Technologies how I can get Vista to index Office 2007 Outlook instead of Windows Mail?

  Hi there, Now that Vista and Office 2007 have been RTM'd, I have installed Windows Vista and then opened Windows Mail to check an installation issue on a Vista Newsgroup. I then installed Office 2007 and connected to our company Exchange server. Unfortunately I now find that Vista Search only finds indexed Windows Mail items and not any Office 2007 Outlook items. I have followed the suggestion of changing Start Properties menu to point to Microsoft Office Outlook and then rebooted and have even rebuild entire search index again, but it still only indexes Windows Mail items instead of Microsoft Office Outlook! I have also opened the control panel - Index Options - Advanced - File Types tap and ...Show All

• Visual Studio 2008 (Pre-release) Validation of inbound data with WCF

  Hello, I have run across an interesting problem with validating inbound data and (in this case) using WCF. I have a data object which has two integers, latitude and longitude which i am expecting as part of a call. In this case, the value that the integers initialize to, 0, is also a valid coordinate in terms of latitude and longitude, so my valiations on the server side can not test for 0 as an invalid value. What i had done on the business object validation is compare the incoming data against int.MinValue which works great for unit testing the local business process (which is what the service is calling when it receives a request) because i can assign that value to the member variables of the local business entity when those member v ...Show All

• .NET Development ZIP File Creation Using C# and Shell32.dll

  Hello, I'm trying to create a zip file in C# using the Windows Shell API (Shell32.dll) with essentially the same code as in the thread titled ("Problem creating Zip File using Shell32.dll" by user "Jeyaraj" - see provided link below) http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=396110&SiteID=1 The code works completely fine on one workstation, but fails in another.

• Smart Device Development how to play mp3/wma in my program?

  With the API, PlaySound and sndPlaySound, it only play waveform file. I try to use DirectShow with WM 5.0 but still can't play mp3 or wma file. My code is maybe wrong, anyone has good sample with DirectShow to play mp3/wma I think the another way to play mp3/wma is using Media Player control. But I can't find the way to make this work. Could anyone guide me to the right way Thanks... I have a problem like this. I am trying to embed windows media player to my C# windowsCE project but it is impossible now. I think I can do this with the functions of wmp.dll but I can't see them with dumpbin.exe. Is there any solution to embed it to my project without extra program like cfcom. ...Show All

• Windows Forms Thread Pools

  I'm using thread pools to update multiple windows forms. The question i have is that when i close a form the thread doesn't get disposed and eventually the app locks-up when i open and close to many forms and won't display any data unless the app is restarted. What happens is the threads are getting stuck trying to update the closed form and when it hits that section of code its stays there trying to find the form but can't. It won't get deleted or die it just stays there until all the available threads are used then i get no more updates. Is there a way to delete the threads as the forms are closed or are they supposed to stay and i just need to add more threads to support what i need to get done Control ...Show All
