• Mandip New xp pro machine, MSDTC not installed or configured?

  Hello everyone, I purchased a brand new shiny development machine last weekend (one of the new dual core 2 processor machines...two thumbs way up!). The operating system on the machine is XP Pro. I am coding a C# 2005 winforms application which requires MSDTC and after opening my C# project and running it I noticed that MSDTC is not installed on my new machine. I thought MSDTC was installed on every windows machine but apparently that is not correct. So when I go to component services to look at the Distributed Transaction Coordinator the "my computer" icon has a red arrow over it instead of a green arrow which makes it look like there is a problem. If I click on the "distributed transaction coordinator" folder under co ...Show All

• SVBG How to use guides with the RecognizerContext?

  Hi! I'm trying to set a RecognizerGuide to a RecognizerContext to improve recognition of lower characters. Therefore I set the DrawnBox, the WritingBox and the Midline - which works so far. But the Recognition isn't really better. I still have the problem that a lower "o" ist mostly interpreted as a big "O" or a zero. Might this be because of the Factoid "OneChar" I don't think so. But even if I'm writing in the gap between the Midline and the DrawnLine-Bottom the recognizer has problems recognizing my lower characters. Here some code: //ic = InkCollector //this = System.Windows.Forms.Panel //middleline = the writing line height in Panel-Coordinates RecognizerGuide myGuide = new RecognizerGuide(); myGuide.Rows ...Show All

• JHarjung Problem with Deliver(), and two filters that don't connect in my code

  Hi I have two problems while trying to build a directshow graph in C++. I wrote a source filter that gets data from a buffer and copies it, with SourceStream::FillBuffer, on its output pin. Then I connect to it a H264 decoder, a sample grabber, and a null renderer. My first problem is that the sample grabber and the null renderer won't connect (Connect() blocks), although they do in GraphEdit. My second problem (but maybe that's a consequence of the first, since the graph is not complete), is that when I run the graph, the Deliver() function, that is supposed to send a sample from my source filter to the H264 decoder, doesn't work. This is quite strange, since it works when I build a graph in GraphEdit with the same filters, except the so ...Show All

• Sam Hobbs Persistenced Workflow Instances

  Dear all, I enabled the SQLPersistenceService and set UnloadonIdle=true. Now, the workflow will be unloaded automatically when idle. But how I can know how many persistenced workflow instances in the Database after host restart Can it be done without using the Tracking service Please help. Thanks. Andy Hallo, Andy. Please try with UnloadOnIdle = true in the constructor of the SqlPersistenceService, when starting the second host. This should automatically load persisted workflows when an event is raised (e.g. their timeout interval is exceeded). Otherwise with UnloadOnIdle = false you must load the workflow manually by it's ID. You will get all the persisted instances b ...Show All

• Insignia Setting volume levels with IAudioVolumeLevel

  Hello, I've been trying to set the level of a particular part by using the IAudioVolumeLevel interface of the API. I can Activate a valid instance of the interface, and when I call GetLevelRange on it, I get a min value of -34.5, a max value of 12, and a step value of 1.5. However if I loop through the valid step values and set them with SetLevelUniform, while comparing the value of the volume level slider in the Control Panel (which goes from 1-100), I get unexpected results. The number on the slider (and volume from the speaker) remains at 0 for the first 8 iterations of the loop until I get to a level of -24 for the SetLevelUniform call, at which point the slider value moves to 1, where it remains until the 8th iteration in the loop ...Show All

• Coc Patrick How to add manifest to setup.exe file?

  How do I add or embed a manifest to a non-self-containing bootstapper or chainer (setup.exe) file. Please help me with some examples. You can do that with Visual Studio. Look in the project settings. If your application is .NET, you will have to add the necessary command line as post build. I recommand you using thememe.exe as the manifest injecter tool provided with VS2005 has bugs. http://www.msjogren.net/dotnet/eng/tools/default.asp Dear Bruce I found your information and is very helpful.

• AdeptBlue In July CTP, using StateMachineWorkflowInstance to obtain CurrentState freezes workflows in that State

  Dear all, I have a working StateMachineWorkflow hosted under asp.net 2.0. I have written a simple routine (shown below) to interrogate the current state of a workflowinstance: public string WfCurrentStateDescription(string WorkflowInstanceId) { // Get the workflowRuntime which was started in global.asax WorkflowRuntime wfRuntime = (WorkflowRuntime)Application[WorkflowRuntimeKey]; StateMachineWorkflowInstance wfInst = new StateMachineWorkflowInstance(wfRuntime, new Guid(WorkflowInstanceId)); return wfInst.CurrentState.Description; } I find that, once I have called this on a workflowinstance, that instance gets "stuck" in the current state and never transitions to the next state, even though code appears to get c ...Show All

• Roger Jennings Drag and drop broken/disabled when running as an administrator ?

    When the software I am developing is (necessarily) relaunched as an adminstrator, drag and drop is then disabled. My app can open explorer windows to drive letters. Drag and drop are also disabled to those as well. Is this behavior really correct How can I re-enable drag and drop features in my software whilst it is running under full privileges Especially DAD for items dropped on MY window which cannot harm anything If I can't work it's a pretty poor show in my opinion, and this OUGHT to be properly documented under UAC so we are all aware of it. To see what I mean, simply run "wordpad.exe" as an administrator, and try to drop anything onto it. One gets a "no entry" sign. To do this browse to C:\program files\wi ...Show All

• Rafael Mores Removing CardSpace

  Folks, This CardSpace suddenly appeared and I can only assume it came down from Microsoft Update. I don't think I really want it consuming resources as I don't think I'm ever going to use it - at least, not any time soon. Can anyone tell me how to remove this component from my system, short of disabling all instances in msconfig and Services, please Apologies if this has already been asked and answered but nothing showed up in a search of the forums. Cheers... CardSpace installs with .net 3.0, so uninstalling 3.0 is the only supported way of removing CardSpace. However, the CardSpace service only starts when an api call is made to use CardSpace, so if you aren't using CardSpace it shouldn't consume a ...Show All

• TinyGuan workflow versionning

  Imagine the following scenario: I have a runtime hosted in an asp.net application, and it is running some workflows (compiled in an assembly with the WorkflowCompiler) that has some HandleExternalEvent activities, so, those instances will be unloaded and persisted, waiting for an event. At some point, I must make some changes in that workflow, but I would like that the instances that are persisted of the older version of that workflow continue to use the "old" dll, and the new instances use the "new" dll. Can I somehow do that without changing the name of the workflows that I compile and without running the markup only And since we are with this, how slower would be running workflows from markup than running ...Show All

• soujanya pause on Fields

  can i pause my graph both on any field that i want in a interlaced video AFAIK, no. Maybe with the EVR, I haven't looked into it and, AFAIK, it's Vista only. - TMH Exactly. For example, if you grab a DV frame once it is decompressed (i.e. one media sample at the level of a transform filter in RGB), you will see that the two fields are combined in the same frame : even lines for one field, odd lines for the second field. On a PC, the renderer normally does deinterlacing before presenting. If you want to be able to pause on each field, you need to split one frame into two frames (one for each field), which means that you cannot use a "simple transform filter&qu ...Show All
