• dsl_beginner Using wimgapi.dll with VB6 - WimApplyImage causes VB6 IDE to freeze?

  I'm writing some code to use the wim imaging api wimgapi.dll with VB6. The code works 100% on capture, with the callback function correctly getting progress information and updating my form with progress bar etc. This works fine when run from within the IDE or from the compiled .exe. The apply image code is a problem though - the WimApplyImage code locks up the IDE part way through. When run from the compiled exe, I get no progress messages to the callback - I do get all the process messages though, and it actually works in that it correctly applies the image, but it stops updating my form until it exits the WIMApplyImage function. Anyone have any ideas I've tried registering the callback both immediately before the WimApplyIma ...Show All

• Abhishekbhadouria IAudioEndpointVolume value and SndVol not in Sync

  I'm working on the vista mixer compatibility layer for our application ( Girder, http://www.promixis.com ) and ran into something odd. When I set the volume with SetMasterVolumeLevelScalar the SndVol slider moves to that exact spot and a subsequent GetMasterVolumeLevelScalar returns the correct value. Smooth sailing so far. Now if I move the slider on the SndVol application and then running my app requesting the volume I get a different volume from the value reported by the tooltip on SndVol. Sliding to 0 and 100% works but intermediate steps are trouble. Not until I call SetMasterVolumeLevelScalar does the SndVol display and report the correct value. I'm currently still on RC1, is this a bug Has this been fixed in RTM ...Show All

• VBAddict How to cancel/ignore an event

  So here is my scenario: I have a workflow published as a web service. This workflow sends out e-mails and processes incoming e-mails. Currently, I have my mail functionality implemented in a local service, and it works fine. The only problem is when the worker process is recycled, the mail service stops polling for mail, at least until the next web service requests restarts the web application. What I'm thinking of doing is moving the mail polling functionality into a separate Windows service or scheduled task. I figured I could have this separate service send a web service notification to the workflow instance when an e-mail is received. Here's the problem: There's no correlation token with web services, and just because the ...Show All

• VectorR3 oscilloscope over running video

  I am trying to display an oscilloscope (aka audio scope) over a running video. The directshow filter i am using to produce the audio scope is in: http://virtualvcr.sourceforge.net/html/virtualvcr/filters/scope.php. This filter creates its own window and produces the scope. What I want to do is, instead of creating its own window, it should display the audioscope over a running video. Please point me in the right direction. Use a transform filter, which is designed to let you handle different formats on the input and the output. Follow exactly the instruction here : http://msdn2.microsoft.com/en-us/library/ms782880.aspx Most important for you are GetMediaType (to provide the output mediatype) an ...Show All

• jatdex InstallLocation in registry uninstall information is not being written when using VS2005 Deployment Project

  Per Vista test case 19 of Vista Logo Certifications, HKLM\Software\Windows\CurrentVersion\Uninstall\{ProductCode}\InstallLocation can not be null. I am using a simple Setup and Deployment project in VS 2005, and I dont see any option to make that happen. I would have suspected that it would do it by itself. A couple thoughts..... 1) Make sure the sequence is not to early or not to late this may require some playing around with. 2) Orca doesn't save and apply the transforms to well sometimes. Reopen your msi after the transform and confirm that everthing is infact saved If you are still having problems, please post to a new thread referencing this thread and the MSI log file.

• rravech Video playback with brightness/contrast ?

  Hi guys. I am writing a C# app ( but C++ answers are fine, I have a C# DShow wrapper, and I can code C++ fine ), and the client has sprung an extra requirement on me, namely video playback ( which is trivial ) on what was before a still image viewer. They want the same controls on video, however, which means they want to rotate the video, and they want to set brightness and contrast on the video during playback. I've googled, and the WMP seems to have an interface, but it doesn't work ( just exposed for skinning ) and I can't see how to do this with DX either. Any help appreciated. That's for the reply. No, I don't want to grab stills, I want the stream itself to reflect the changes. I'm doing brightness/contrast via mat ...Show All

• WayneSpangler Vista ListView Focus/Selection style

  How can I say that the ListView control should use the focus/selction style like in explorer My items have just the blue background, not the much cooler explorer 3d stuff. btw: I'm using the application manifest.

• Fatlabmonkey Error message - "The memory could not be read" - Help please!
