• peedee loading a workflow instance after changing the workflow

  Hello. I'm having problem loading a workflow instance after my state machine workflow has been changed. The runtime GetWorkflow return an error saying the index is out of bounds. What am I doing wrong Samples for dynamic update can be found here . How are you changing the workflow Are you adding some new workflows and compiling or using dynamic update If compiling, you need to make sure that you increment the version and make sure that the workflow runtime has access to both versions if you have instances based on the original version still running. To update the running instance of the original version you would need to use dynamic update, it is not automatically done. If you are currently using dynamic update can you po ...Show All

• Sumesh Nair Workflow + Offline + SmartClient

  Hello guys, I'm in the middle of an architecturing project, and basically we are talking about 4 or 5 workflows with some complexity, and integration with 3rd party ERPs. The cath is this: all users are working in different offices, ocassionally connected, so the solution MUST be SmartClient (web is not an option). When they are off the network , they should be able to start a workflow, or to approve some pending, and then when back online, synchronization should occur. The creator can be in one office, it posts to the server for some ERP validation, and then it goes to step 2,and that is another user from another location, and so on. Basically the question is: is it possible with WWF Or it would mean more work than using somethin ...Show All

• Dan L 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.

• Noah Phense Web Services on Devices - WSDAPI - Wsdcodegen.exe

  Hello, This is a question related to the April Vista Developer Story on Web Services For Devices . The Story talks about the new WSDAPI - a c++ COM library for communicating with network connected devices supporting WSD. The document refers to a tool called "Wsdcodegen.exe" as being a core component of WSDAPI development, to aid in the creation of a WSDAPI proxy service. Unfortunately I have been unable to locate this tool in the Windows SDK or elsewhere. Has any one else had any luck in locating this tool, or barring that, perhaps found a sample of a manually created service using WSDAPI Thank you for any assistance you might be able to provide. Cheers, Scott Bailey ...Show All

• Denis Pitcher DoubleAnimation.duration Not Accessable at Runtime

  Is this a bug or a feature I have an animation on a video player sample I am working on. What I am trying to do is create an animation that moves a thumb object from left to right as the video plays. So I registered for the MediaOpened event and I tried this: function theMediaOpened(sender, args) { var thumbAnimation = sender.findName("thumbAnimation"); thumbAnimation.duration.seconds = sender.naturalDuration.seconds; thumbAnimation.begin(); } The thumbAnimation is a DoubleAnimation. The problem is that thumbAnimation.duration doesn't resolve to anything. Ideas I would try to set thumbAnimation.duration directly by converting naturalDuration to a string. Something to the effect of: // assuming naturalDurat ...Show All

• kcon DirectShow: get_StreamLength inaccurate

  Sorry for yet another DirectShow query. I'm using the IMediaDet interface to find out the footage duration and consequently the number of frames in the footage for lots of different formats. I've tried two methods to obtain the number of frames. 1. Call get_StreamLength and get_FrameRate and then multiply the stream length by the frame rate to get the number of frames. 2. Use the number of frame calculated in 1, subtract 15 from it (magic number, nasty I know but I'm getting desperate) to get a frame number 15 frames from the end of the footage, let's call it frameNumber2. Then run the graph from frameNumber2 and use the IMediaEvent interface to WaitForCompletion. Check that the event is the EC_COMPLETE event. Use the IMediaSeeking ...Show All

• Jeanvo Can you instantiate a different Workflow by using a Custom WorkflowLoaderService?

  I'd like to get the Workflow from an assembly file and dynamcially instantiate it by creating a custom WorkflowLoader Service. I've tried this: WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(ProxyWorkflow)); -- where ProxyWorkflow is nothing more than a blank activity (I've also tried making it a blank SequentialWorkflow) and in my custom WorkflowLoaderService, I try this: Activity workflow = (Activity)Activator.CreateInstance(_workflowType); return workflow; --where _workflowType is a SequentialWorkflow loaded from an Assembly file However I get this error: System.InvalidOperationException: Can not create workflow definition.

• dbcuser throttling to not overrun MaxSimultaneousWorkflows

  If I have a WF host running on a server in which I want to have asynchronous workflow execution, I assume I need to manually control how many instances I start to not overrun the thread pool I didn't see a count property on the runtime, so is the correct way to get this to call GetLoadedWorkflows and check the count on that collection I'm a little concerned this may not accurately represent the total number of threads in use. To put this another way, if I have a message queue being read by a Windows Service host, and each received message invokes a workflow, whats the correct way to optimally keep the Workflow thread pool busy but never overrun it Hi, this post provides more details about threadi ...Show All

Now that I have upgraded to Vista, I am not able to get to the Exchange server. is there a simlar hotfix that will allow the HTTP tunnel or is there some config in Vista that will let me achieve this using Outlook 2003 Bonus, I have a copy of Outlook 2007 which I would like to upgrade to as well, but 1and1 does not yet support this, at least not in tech support. In thinking this through, this is actually a windows issus vs. outlook (I think) so if i can get vista working, then theoretically Outlook 2007 shoudl work as well. Thansk t.a.

  Say you have a parallel activity, with two eventSink activities on either branch. Is it possible to have both eventSink activities “listening” to the same event, and use correlation token to decide which activity to be executed Mikael This is possible as I found out. Please look into the Hands-on Labs Beta 2, Lab 05, Exercise 02. There is a complete source code example. I use Beta 2.2 and it works. ...Show All
