• j_ames2006 Problem installing windows workflow extensions for Visual Studio 2005

  Has anyone had any problems installing the workflow extensions (RC5) for Visual Studio I have this installed however every time I try and run Studio it displays the splash screen and then hangs using 99% of the cpu. If I run Studio in safe mode then I can get in fine and the workflow options appear in the create project dialog however if I create one of them then I get the error message: --------------------------- Microsoft Visual Studio --------------------------- The project file 'C:\Documents and Settings\gordon.NT\Local Settings\Temp\w42cddt1.gwy\Temp\WorkflowConsoleApplication1.csproj' cannot be opened. The project type is not supported by this installation. --------------------------- OK Help --------------------------- ...Show All

• TrevorW Which version of Vista use for testing?

  Hi everyone! I need to test some applications I made in last years on Vista. Which version (home, business,ultimate..) I have to test for compatibility It's necessary to test on ultimate (the most complete) to cover all compatibility problems Tnx to all This topic is a little bit bigger than just that one question. Just being on one OS version doesn't mean your compatible. You need to review the following information to get complete coverage. Works with Vista Logo is obviously encouraged but the following will lead you in the right direction. Details on Vista compatability can be found at http://www.innovateonvista.com Here's the application compatability toolkit http://msdn2.microsoft.co ...Show All

• arkiboys Writing to Global Shared memory from an Application in Vista.

  Hi all, Global shared memory is created by a service which is used by my user mode application to communicate with the service through global mutexes and events. This as of now works well in Vista RC1. 1) Are there any restrictions that an application should not write to global shared memory already created by service This application does not has any elevated privileges. 2) Can application created global named objects like event and mutex Again the application is running under a standard user privilege and not as admin. 3) Can a 32bit application on a 64bit machine get interfaces to a 64bit Local server COM object Is there any special processing required in the 32bit app or in the 64bit local server COM object.

• suddenelfilio Some bugs I found in Vista RC1

  I'm not a beta tester of Vista, so I don't know where to report bugs. Maybe someone from Microsoft reads this and forwards it to the developer team. In a SysTreeView32 which displays state images, double-clicking a state image toggles it 2 times. On Windows XP it is toggled 1 time only. Is this the expected behavior In a SysTreeView32 with the TVS_EX_NOINDENTSTATE style, you can't toggle state images using the mouse. TiKu Hey I have the same video card. Heres the solution. Go into your video settings and set the resolution of your monitor and your TV to the exact same. (usually 1024 x 768) then everything becomes clear; as they say. these forums are for software development....so, for your bug reports, there is u ...Show All

• JBartz Image formats?

  What image formats are supported Is there a reason GIF is not supported Again I've run into a situation where nothing would render and yet no error handler was called. This time apparently it's because there was an <Image> element with a "Source" attribute referring to a GIF file. It's very frustrating to try to work with WPF/E when it doesn't provide feedback for cases it knows it can't handle. In this case I rather doubt it's an XML validation error. So why isn't the error handler being called I can understand if the WPF/E implementation at this stage doesn't support some image formats. And I can understand that the documentation isn't complete. But I'm surprised that GIF files appear not to be supported, given ...Show All

• kotov_ks Persistence and long running workflows

  Hello all I am developing a specialist content management system that uses state machine workflows to control the content throughout its lifecycle, which could last from a few days to a number of years. I have implemented a custom persistence service that uses Activity.Save and Activity.Load to (de)serialize the workflow state into and out of my backing store. This all works fine and I am very happy with it. However there is one major issue: Whenever I make the smallest change to a workflow none of my saved workflows can be deserialized. Instead it throws an IndexOurOfRangeException from ActivitySurrogate.ActivitySerializedRef.OnDeserialization This part of the framework does not appear to be designed for user extensibili ...Show All

• haihtomy Slow startup times

  Hello, I have just installed WWF on my development system. I have noticed that the start/load time for an extremely simply workflow (ie-hello world) is slow. This isn't just the runtime of the application either.. Here is some pseudocode, main print 'in main' workflow.setup print 'wf setup' workflow.start workflow.waitforexit print 'done workflow' The application sits there for about 10 seconds before even entering main. For all intensive purposes please assume that my development machine has never been connected to the internet. Anybody have ideas why this could be happening This seems to be environment/system related. How does the performance compare with against a normal C# console application I ca ...Show All

• Orbix SqlWorkflowPersistenceService lock expire tests irrelevant?

  Various queries in the stored-procedures in Microsoft.NET\Framework\v3.0\Windows Workflow Foundation\SQL\EN\SqlPersistenceService_Logic.sql are testing whether (dbo.InstanceState.ownerId = @ownerId but also whether the lock is (not) expired !! AND dbo.InstanceState.ownedUntil >= @now) IMO this last check is irrelevant when you already verified that you are the owner of the lock. Here is what happens: I have a state machine workflow with a state containing a delay activity followed by a setState activity. The delay activity idles but tracing shows that my workflow is reloaded from the persistence store !! First the lock times out, then the delay. No loading (at first) because my workflow was already loaded ...Show All

• isaksp Either method could not be found or method signature does not match the delegate type.

Either method could not be found or method signature does not match the delegate type. My project still compiles and the event is still fired but I would really rather not have the bang over every instance of the activity.
