• Andrei S. How to get "NextStateName" in Invoke event inside the workflow

  In a state, there are several EventDrivenActivities, in each EventDrivenActivity, there is a HandleExternalEventActivity and a SetStateActivity, for the HandleExternalEventActivity, there is a corresponding Invoked EventHandler, I want to do something in it, and the first thing I want to get is the TargetStateName of the SetStateActivity in the same EventDrivenActivity just below the HandleExternalEventActivity. I know the PossibleStateTransitions, but it is not what I want.

• Paulo Reichert Is Windows SDK final version or RC1?

  The download page for the Windows SDK (publish date 4th Nov) says nothing about it being RC1, yet the license agreement (viewable on running the web setup file) relates to Windows SDK RC1 and states the SDK agreement expires 31st Dec.

• ThePatrickP Support for Streaming Servers ?

  I am currently trying to find out if support for any streaming architecture has been implemented in the FEB2007 release; ideally the Windows Media Server WMS architecture. I would like to be able to access streaming content under any of streaming protocols ideally rtsp:// or mms://. Our architecture is setup on WMS and I am typically working with 45-90 minute recordings. Due to the limited support for WMP on Mac OS X as well as compatibility issues with the latest Intel based macs, I am very eager to be able to replace the embeded WMP with a WPF/E based player, however I need the ability to seek to random points in a file. Also in looking at the docs, WPF/E is said to support WM9, I was wondering if it will be suporting all WM9 codecs ( ...Show All

• Aleniko29139 Error 0x8004D00E on SQL Server 2000 + Windows 2000 SP4

  We have an ASP.NET application running on Windows Server 2003 whose database backend lives in a different machine which runs SQL Server 2000 and Windows 2000 Server SP4. Whenever we try to use System.Transactions we get errors. We are almost sure that the problem is related to MSDTC refusing network connections. We tried to run the same thing using Windows Server 2003 in the backend server, and we were able to make it work by configuring MSDTC security using the COM+ console. However, we still need to support Windows 2000 for the backend. There is apparently no GUI for MSDTC security on Windows 2000, and the registry settings we have tried so far did not work. We think this should be a very common issue, but we have ...Show All

• yonelay Using smartcards in a service - SCardAccessStartedEvent

  Dear all, Migrating our core development platform to Windows Vista, one of our Windows services using smartcards is failing. We have debugged the problem and found that the event provided by the function ScardAccessStartedEvent does not receive notification. This event is supposed to signal when the SmartCard Resource Manager starts. As we have a WaitForSingleObject(event,INFINITE), the service hungs. Testing the same service as an ordinary executable ( registering with -regserver ) I can see it works properly. In XP it works properly both as an executable and service. I have read something about Service Hardening in Vista and I guess it may be caused by privilege reduction. So, I've created some code to enumerate the existing ...Show All

• JeffJohnsonMVPVB WWF runtime refers old workflows

  Hi, I have deployed WWF in a console application(Host). While developement, i have created some un-wanted workflow for testing purpose. In this machine WWF is working as expected. Later I had to copy the project in a DIFFERENT machine with only the relevent workflows. Also I have restored the DB s - WorkflowPersistence -WorkflowTracking from the 1st machine. But as I have mentioned, I created some un-wanted WF in the 1st machine, hence after copying the project in the 2nd machine(new), workflow runtime still trying to load the un-wanted workflows. But in the new machine I never copied the un-wanted workflow. Hence WF runtime is not able to load the un-wanted workflow & giving error. I have deleted the unwanted workflow r ...Show All

• N_John Need a callback per frame

  I've tried using EC_VMR_SURFACE_FLIPPED to get a message on every frame but it never happens. I know I'm doing something wrong but com is so convoluted and I haven't been able to find anyone who has attempted to do what I'm doing. I just need a function call on every frame to sync the dshow frames with another library. Anyone know the best way to do this I'd like to avoid the overhead of the sample grabber copying the buffer over every frame since I won't use the data. Thanks, Jake Read this post and I think that it would help me also.
