• AustinMcElroy GrpahEdit records fine, corresponding code does not

  I have got DirectShow running nicely for viewing a standard webcam video stream. The graph is registered so GraphEdit sees it-- here is a summary: capture filter(Logitech web cam) -> Smart Tee -> Capture branch-> MUX -> File writer -> Preview branch-> Video Renderer However, when I capture the stream and save it to an .avi file, the file is unreadable. The strange part is that if I use GraphEdit to remotely see the DirectShow graph and then run the graph via GraphEdit, then the .avi file is fine. The properties page of the good (GraphEdit written) file shows a framerate while the one run directly from code does not (all other parameters such as size, resolution, compression format ...Show All

• Bloom326984 Microsoft.DirectX.AudioVideoPlayback.Audio - File LOCK

  This is interesting and I really need some help please. While using this namespace to play an mp3 file, one might call this method. audioPlayer = Microsoft.DirectX.AudioVideoPlayback. Audio .FromFile(fileToPlay); You would then just call audioPlayer.Play(); Here's the problem: This object does not support playing a file from a memoryStream, but a physical file. So if your media is in a database for example, you must write the file to the hard drive and then play it. So far so good. However, once that file has played through this object and you direct it to play the "next sound", you CANNOT delete the first one! DirectX seems to keep a handle on the file you created. Thus, in a multi-sound application the temporary files ...Show All

• Rush hour fullscreen exclusive mode with VMR9

  I'm a bit confused on how to go about implementing a fullscreen screen exclusive mode custom allocator presenter with VMR9. The VMR7 samples I've seen do a " CoCreateInstance(CLSID_AllocPresenterDDXclMode...) ", then go on to configure this ready to go allocator presenter. The documentation on the MSDN about this says " This topic applies to the VMR-7 only. In the VMR-9, you enable exclusive mode by supplying your own exclusive mode allocator-presenter. This is relatively straightforward if you use the IVMRSurfaceAllocatorNotify9::AllocateSurfaceHelper method. The VMR9Allocator sample shows how to implement a custom allocator-presenter.". I do already have my own VMR9 allocator-presenter, based on the VMR9A ...Show All

• Dnieto23 Service With a Window

• leozworld Exception on raising an event

  Hello, I'm developing an example project very similar to expense reporting (lab01), with two event handlers. I can fire the first one (submitted event) without any problems, but when I try to raise the second event (reviewed event) I get an exception that sais: "EventDeliveryFailedException was unhandled" and the message is "Event "RevisatCOF" on interface type "WorkflowValidacio.Interficie" for instance id "ef46e5fa-64c7-4343-9d3c-c62b829f9c37" cannot be delivered."

• ReyCri Workflow state serialization to XML

  Hi all! Does anyone know how a Workflow instance state can be persisted to a format that is different from the default binary format (the SqlWorkflowPersistenceService uses the WorkflowPersistenceService.GetDefaultSerializedForm() to serialize workflow state). We use a custom OracleWorkflowPersistenceService and currently we use the WorkflowPersistenceService.GetDefaultSerializedForm() to write the state information to an Oracle BLOB column (is analogous to the 'Image' type in SQL Server). However, it would be interesting if the state couldbe stored in a readable format like XML. The reason is that Workflow types (.NET Classes) can evolve over time (properties can be added or removed) and as such the serialized state could become 'incomati ...Show All

• Muhammad Mohtashim Jangda Workflow Foundation (.Net 3.0) official release - What's changed?

  Has anyone run across a document that details the changes in the workflow foundation from the September CTP to the official release Thanks, Don There is a document on the community site that outlines changes from the beta 2.2 version to the RC (and RTM) versions. You can find that here . Specifically, there are no changes between what was in the September CTP and the release version. Let me know if you have any other questions! If you look in C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0, you will find the Workflow DLL's to have the same July date as the Sept CTP I think. So I don't think anything has changed, though of course I have no inside info. ...Show All

• The WB How to pass parameter in ManualWorkflowSchedulerService

  when using WorkflowRuntime.CreateWorkflow, there's a overload, so that we can pass some parameter to workflow but, in statemachine workflow, if an instance already exists we use ManualWorkflowSchedulerService to RunWorkflow how to pass the paramter To answer you first question, even if you are using the ManualWorkflowSchedulerService.RunWorkflow, you still need to create the workflow using WorkflowRuntime.CreateWorkflow. So you can still pass the parameter the normal way. For your second question, parameters passed to a workflow are mapped to properties on the workflow that can be accessed by any of its children activities anytime during the lifetime of the workflow.

• SDyke WPF/E Export: Text as Path, how to change?

  Hi, why isn't it possible to export text as an WPF/E XAML Text element. I currently get all my text exported as a path instead. I'm missing something Michael I'm assuming you're talking about the Expression Designer again. I think the reason you're seeing that is because Expression Design is really for creating graphics, not neccessarily for doing things like what WPF/E is used for. Think of it more like Paint rather than Word. What we really need is for Blend to support WPF/E. :) We're currently working on improved tooling for WPF/E and I realize it's painful where we are today. The workflow I usually use is to do the rich graphics in Design then switch to Blend for the WPF/E XAML (incl ...Show All
