• noonie Dependency Property

  I have a custom activity derived from HandleExternalEventActivity that I have generated from a interface using the wca.exe tool. On this activity there is a dependencyproperty Approved (type bool) generated. The value of the property is set in the eventhandler for the activity. I have placed my activity inside a while activity that I have set up to have a Declarative Rule Condition that is set up like !this.pageApproved.Approved When I debug my custom activity and more precisely the get/set of the dependencyproperty. I see that when I send an event to the workflow that sets the property to true everything seems nice [ ValidationOptionAttribute ( ValidationOption .Required)] public bool Approved { get { retur ...Show All

• LJM89 Whats the difference of xbap and wpfe?

  When should I use one or the other!! For what kind of applications xbaps are regular programs that runs within the browser in a somewhat restricted enviroment. the requirements for running an xbap is that you have the full .net 3.0 runtime installed (~20mb) and you are using IE 6 and above. With this in mind, the only real usage for xbaps as I see it is for intranets, where you can manage your clients, and know that all of them meet the requirements. wpf/e in it’s current state is simply another way of drawing and playing .wmv files, and you can write the logic using javascript. what wpf/e is going to be is another matter, the wpf/e team seems to be very secretive about what the real end-goal is with this. we all hope tha ...Show All

• Tdar Normative Schema for WF XAML?

  Hi, I don't think this question has been asked since last November. Is there a schema for XAML I'm working on some bits to generate workflow types and would to do less reverse-engineering of what Dev Studio produces. Thanks. - Erik I don't agree. I understand that XAML itself is an outer wrapper for WPF or WF, but that doesn't mean that "xs:any" is the best Microsoft can do to document XML formats for those subsystems. From the stuff I've seen in XAML so far, I haven't found anything that couldn't be represented in a proper XML Schema document. I don't really need a proper XML Schema for XAML/WF -- I just want documentation about the format. I can build my own schema if needed with whatever constrain ...Show All

• Misiacik7 WTSWaitSystemEvent and WTS_EVENT_FLUSH fails on Vista RC1

  Calling WTSWaitSystemEvent with WTS_EVENT_FLUSH from thread A while thread B is blocking on a call to WTSWaitSystemEvent with WTS_EVENT_ALL should force the call in thread B to return. The following console application shows the problem. The app runs correctly on XP. #include <windows.h> #include <WtsApi32.h> #include <stdio.h> // Sample console application that shows the problem with forcing // a call to WTSWaitSystemEvent to return on Vista // // Program Output on XP Program Output On Vista // // Going to Flush Going to Flush // EventFlags = 0x0 Going to Flush // Going to Flush Going to Flush // EventFlags = 0x0 Going to Flush // Going to Flush Going to Flush // ...Show All

• RizwanSharp How to interpret registry values containing "@filename.dll" ?

  Our Win32 app currently reads various values from registry strings. But in Vista, these values no longer contain the string we're expecting. Instead, they contain something like: @themeuidll.dll.-852 I assume that this means we need to access the themui.dll file and reference something by 852 Is it that we need to load the dll then extract the string resource identified by the ordinal 852 to get the actual string value we're looking for I'm pretty new to Vista so any direction on this would be most welcome :) Thanks!

• viliescu Normative Schema for WF XAML?

  Hi, I don't think this question has been asked since last November. Is there a schema for XAML I'm working on some bits to generate workflow types and would to do less reverse-engineering of what Dev Studio produces. Thanks. - Erik Given that XAML in and of itself, without attachment to WPF or WF, is an XML-based syntax for object instantiation .. the schema would rather depend on the underlying object model being instantiated. Sure, there are rules for the format of defining object instantation, but I don't think you can truly do an XSD validation against a XAML file without also being able to attempt to instantiate the classes to which the XAML refers. I also would like to see a schema. I've seen this ment ...Show All

• hammar Recorded Video File Has no Length

  Working on Windows Mobile 5.0 Using as a base the sample "CameraCapture " from the PocketPC SDK. My code below. I call the function to start recording video. It creates the asf file specified but that file is unplayable on the phone. Windows Media Player (latest version and a few older versions I tried) cannot play it. Nor can VLC. When I look at the file in AVICodec (multimedia file analyzer) it says: C:\camcap.asf File : 140 KB (0.00 B), duration: 0:00:00, type: ASF, 0 audio stream(s), quality: 26 % Video : 140 KB, 0 Kbps, 0.0 fps, 176*144 (4:3), WMV3 = Windows Media Video 9, Supported I haven't specified any audiostreams so there shouldn't be any. 176x144 is proper resolution (as I haven't changed it, and from IAMStreamCo ...Show All

• FredMunro Accessing workflow instance members from WorkflowInstance (runtime event handlers)

  Hi All, Is there a way to retrieve a strongly typed reference to the actual running workflow from a WorkflowInstance instance More details: I have a runtime event handler (loaded, idled) that receives a WorkflowEventArgs parameter. In that method I would like to access some of the instance properties (DependencyProperties) of my own workflow class. The only object I have in that method is a WorkflowInstance with an InstanceId. So the question is, how can I get a MyWorkflowClass instance if I have an InstanceId Thanks in advance. Messaging and tracking are indeed the only ways to access workflow fields and properties.

  I recently bought a USB stick to watch DVB-T television. Whilst the hardware is great, the software is appaling. the compnay have told me they use DirectShow. I have looked at the documentation etc. but it is really confusing. Can someone point me to a resource on how to build applications to interface with a BDA compatible DVB-T device, using DirectShow, for people who don't know anything about the subject Thanks. moved to DirectShow forum If you have the Platform SDK installed you should be able to use Graphedit to create a Filter Graph that will operate the USB device.

• TheWardy What is the rationale behind not having a static method to retrieve the current workflowruntime instance?

  After doing quite some work with windows workflow I am starting to feel that there is one thing that is coming back every time you work with the WF runtime and that is getting the current running instance of the WFruntime. What I just can’t grasp is why there is no static method on the workflowruntime class to retrieve the running instance. (or by name if you have multiple instances running) In every sample you look you see that not having this method makes the developers suffer and you need to make assumptions that are not always true. e.g. take a look, at the WebServiceInput activity and try to use it without the generated configuration when you publish the service. (name the configuration something else then “workflowRuntime”!) ...Show All

• Francis Shum How to Track StateMachine Workflow in Database?

  1. I tried to modify the Hands-On Lab Sample "Hosting Workflows to a StateMachine Workflow" from Sequtial Workflow to a StateMachin one , but it didn't work, the Sequntial one worked fine, and when i changed it to a StataMachine one, then the database stored nothing, and TryGetWorkflow Method always return null. Is there anything different between storing Sequntial Workflow and StateMachine one 2. If the question above resolved, can I get the running Workflow's current state's allowed Events like the Property stateMachineInstance.MessagesAllowed in Hands-On Lab Sample "Creating State Machine Workflows" 3.

• mrboldt Drag and drop?

  I'm interested in writing automated tests for a rich WPF client that has drag to move and drag-select functionality. I like the UIAutomation stuff a lot. To round out my tests, though, I'll need to implement mouse click-drag-release behavior. What's the recommended approach for this Win32 SendMouseInput Any guidelines or code samples to point me to Thanks! Luke I also need this functionality but haven't found any solution to it yet. If I do I'll post it right away...hopefully Microsoft has a nice solution in UIA itself, but I don't think so. Grtz, Nick I don't think UIA supports those.
