• Jehan Badshah Uninstall Vista SDK RC1

  Hi To install the final Vista SDK (6.0.6000.0) I need to uninstall the Vista SDK RC1 (6.0.5536.0).. I have tried this through the add/remove programs, but something did go wrong and it was not uninstalled. In a previous thread i have read that installing the RC1 SDK would resolve this problem, but that is no longer avaliable on the webpage. How do I remove the old SDK or force the installation of the new SDK Regards Thorbjorn Before hacking around with the MSI files, you might want to try re-downloading the previous SDK, either install it or repair it, and then uninstall it. I realize that's a bit of a hack, but the pre-release SDKs had some bits that weren't fully baked. ...Show All

• Adam Plocher vista blocks application at startup

  Hi, I'm a software developer and I have a question about Vista. Our application (a .NET 1.1 app) requires Administrator access and we have the "requiresAdministrator" access level defined in the application manifest. That part is working fine. However, our application needs to startup when the computer boots so we have it in the "startup" folder. For some reason (I can't imagine why) Vista puts it in the "blocked startup programs" list and the user needs to manually launch it. This is not acceptable for us. Is there any way to circumvent this problem And by the way, why is there no way for the user to say "I want this app to run every time I reboot so stop blocking it!" On a side note, I not ...Show All

• Gangy more than one Video Renderer, the get_FullScreenMode() always return E_NOTIMPL!

  In my program there are two video render filters, one for local window and the other for remote. However, when I did the following: IVideoWindow *pRemoteVideoRendererVW=NULL hr = Graph.gcap.pFg->QueryInterface(IID_IVideoWindow, (void **) &pRemoteVideoRendererVW); if (hr!=S_OK) { Log.Log(1,"IID_IVideoWindow failed %08x",hr); return; } LONG lMode; hr= pRemoteVideoRendererVW->get_FullScreenMode(&lMode); if (hr!=S_OK) { Log.Log(1,"CCyklOneDlg::OnFullscreen get_FullScreenMode failed %08x",hr); goto exit; } Everything went through without any error. Excepting the pRemoteVideoRendererVW returned by the QueryInterface() does not guarantee that it was the remote windows. It sometimes returns the local vid ...Show All

• M Kenyon Tutorials on WF and WPF

  Good Morning Fellow Questers I’m looking for help on two things. 1. The location of tutorial or sample code that use WF and WPF together. 2. Insights, facts or guesses on why there is so little MS resources devoted to using WF and WPF together. Thanks and I’m looking forward to your response Make it a great day Mike Greenway Here's a sample: http://msdn2.microsoft.com/en-us/library/aa970891.aspx Also, here's the MSDN topic on integrating between the technologies. The integration is encouraged, and there are some samples, perhaps not as many as we would like yet due to resource issues.

• Rashar Security token without authentication

  Hello, I would like to know if it is possible for the user to use a managed card (get a security token) without requiring the user to authenticate himself Thanks for your help, Dear Caleb, Thank you for your answer. Cardspace supports a few authentication methods only, and you can see that in other threads of this forum, some of us are asking how we can implement another authentication method. Getting a managed card and its attributes without authentication could allow the RP to process the authentication method it wants. I mean that the managed card could contain information about how the RP should authenticate the user. I mean that the authentication could be done by something else than the STS, after the card's retrieval. The c ...Show All

• barkingdog How to install vs2005 extension for WWF?

  Hi all, I downloaded the VS2005 Extension for WWF from this link http://www.microsoft.com/downloads/details.aspx familyid=5D61409E-1FA3-48CF-8023-E8F38E709BA6&displaylang=en#Instructions However, I can't install it.

• detzX UnloadOnIdle Memory Leak???

  In the ASP.NET WF application we've written, we're utilizing the SqlWorfklowPersistenceService, SharedConnectionWorkflowCommitBatchService and a custom ExternalDataExchangeService.

• JohnnyP34 vista and UNC paths and mapped drives

  Hi, My application is stored on our network in a location K:\path\to\app.exe. each user double clicks on the exe and installs right off the network. In vista when you do this instead of launching K:\path\to\app.exe it changes the command to a \\servername\share\ format, \\server01\path\to\app.exe. Unfortunatly for legacy reasons it will only work with a drive letter and not the UNC path. So before I look at changing the app's code, Is there a way to get past this in Vista RC1 Thanks Shane I am having the same issue using RC2 Hay Guys The same problem is facing by me while runing my windows application in UNC path.

• Luis D. Rojas Fault Handler and Bindable Properties

  I'm using the June CTP of WF. After I promote Bindable Properties on my FaultHandler I'm getting a weird popup in the VS environment. DependencyProperty 'Fault:System.Workflow.ComponentModel.FaultHandlerActivity' does not have an associated CLR property. All non-attached Dependency Properties should have a corresponding CLR property. Any ideas Well - Fault is now a read-only property. I assume that is why you are getting the error - I guess the question is why is the property promotion menu promoting it. I'm trying to log Exceptions that happen in an EventHandler.  I was trying to put an faulterHandler that caught all generic System.Exception and then write to the EventLog an ...Show All

The call to SetSpeakerConfig() succeeds, but doesn't actually change anything. Is there any way other than by using the Sound control panel. Hi Mitch, Base on what you told on Forums, it doesn't seem possible to change the speaker configuration. I read the reason why you decided to do so, and even if I found it not convenient, I do respect your decision. Howev ...Show All
