• Carolyn Evans Vista (RC1) Bug??? An old Win32/DirectShow WMV player won't work under Vista RC1.

  Hi, I've got an old DirectShow Win32 application (plays WMV video files) which works well under Win ME, 2000 and XP but does totally strange things under Vista RC1. First it fails to play a file, sometimes I see just the first frame. Then when I use IMediaControl to jump just a few seconds/frames forward the video starts playing but it is upside-down or actually mirrowed!!! This problem  has nothing to do with WMV files I've got, the same happens when I play Vista's sample WMV files (C:\Users\Public\Videos\Sample Videos). I sripped down the brocken app to the minimum, here is the code (I compile it under Visual C++ .NET 2003). I appreciate any help. #define WIN32_LEAN_AND_MEAN #includ ...Show All

• Steve Eckhardt State workflow bug

  Can anyone else verify this bug https://connect.microsoft.com/wf/feedback/ViewFeedback.aspx FeedbackID=171215 It's very basic - a state workflow won't correctly handle HandleExternalEvent if it's in an EventDriven which is at 'workflow' level, rather than inside a specific state. It will handle HandleExternalEvents if they are inside a state & eventdriven though. I have an example file if anyone wishes to look. EDS does throw an exception - its just that it catches it and doesn't consider it "fatal" so it eats it. Here's how I did it. First - on Tools-Options-Debugging - I disable "Just My Code" (this is the stupidest default they've ever put in VS IMO). Then bring up the exceptions dialog (Ctrl- ...Show All

• b182f117 Track HandleExternalEventActivity states?

  Hi I have a couple of custom activities which inherits from a class EventBase which inherits from HandleExternalEventActivity. My plan is to use SqlTrackingService to track whenever a workflow instance enters/completes such an activity. The idea is then when the host should raise an event it could query the SqlTrackingService for all instances that has entered the corresponding activity (but not completed meaning they are currently waiting for the event). And then the host would know which instances to raise the event to. My question is how such a query for instances that are qurrently inside an activity should look like In other words I would like to ask the SqlTrackingService "Give me all instances currently waiting for eve ...Show All

• grolich Determine if WorkFlow is loaded.

  Hey All, I'm trying to persist a workflow when my application closes unexpectedly. I have the SqlWorkflowPersistenceService running just fine. The frmMain_FormClosing works if the workflow is running, but fails if it has already completed.

• jovert CSource based Filter and dynamic pin creation/destruction

  My filter derived from CSource. I have one input pin. This input pin derived from CBaseInput pin. I'll create my output pin after my input connected. However I'd like to destroy after my input pin disconnected. How should I do CSource::RemovePin couldn't delete pin. My filter's purpose is split. I'll create more than one output pins. Source filters aren't supposed to have inputs pins, not real connectable ones anyway. To create a splitter filter (like a parser) you need to derive from CBaseFilter in order to have full control over dynamic pin creation. You can look at sample filters like InfTee for how that part works. ...Show All

• Alessandro Moacyr Duarte STANDBY power broadcast

  Hi, I am working on interrupting the standby and hibernate of Windows Vista and am handling WM_POWERBROADCAST. I found that in XP the hibernate/standby msg parameter is PBT_APMQUERYSTANDBY while in vista it is now something else. can someone point me as to what the value changed to I cannot allow the machine to go into hibernate or standby. Hi, I have one problem. I'm calling SetSystemPowerState call to send the system to a sleep state in Windows Vista on a timer event. WM_POWERBROADCAST message is received, but the wParam is not set to PBT_APMSUSPEND. Instead, I'm getting PBT_RESUMECRITICAL message.

• Rattlerr Any future for input controls?

  I haven't seen a list of planned features for WPF/E but are there any plans to add input controls such as a textbox (and textarea type control), button, dropdown, etc. I know that gets into a whole different realm but I think to truly make WPF/E something capable of more than just fancy animations (which I admit I like), having input capabilities is necessary. Some very cool data entry forms could be built that handle validation, etc. in creative ways. Imagine a textbox shaking for instance (a mini textbox earthquake) when it contains invalid data. Or, correct textboxes could be faded out bringing the incorrect ones to the forefront so the user could see them better.

• MegaBYTE444064 Here's How To Use Your Own Bind Dialog

  Hello Everyone, I've created my own custom PropertyBindDialog because the one that Microsoft provides is pretty deficient. Unfortunately my own custom PropertyBindDialog will not be used after I call Activity.SetBinding - after I do this for a given property my own custom PropertyBindDialog is ignored and the Microsoft BindDialog is used. Here's some of my source code... The problem occurs when I call SetBinding on the property Test. After I call SetBinding, my PropertyBindDialog is no longer used when I want to edit the Test property - the Microsoft BindDialog is used and my custom PropertyBindDialog is ignored.

• Sonia G. reading event log; compatibility xp and vista

  I have posted this on the vista sdk forum. As this is also a compatibility issue, I am posting this on the compatibility forum also. I have an application in unmanaged VC++ working successfully on XP. However when I run the application on vista I get errors. The application creates an event, and uses the NotifyChangeEventLog sdk function to notify my application of any new event being written to the windows event log. I then use the ReadEventLog to read the event log record. All these functions are supported on the Vista and works fine. However, things get murky hereafter for the vista. I use the registry to read the EventMessageSourceDLL which then provides me the event description. However this part is not working on Vista, ...Show All
