• Euclidez How to NOT persist a workflow instance when it is completed?

  I've found when a workflow instance is completed, it will be persisted automatically. Is that true If yes, how to get rid of it The workflow instance is persisted each time you indicate to the runtime to unload or when the workflow becomes idle. To me, the last time a workflow is persisted, can happen anytime the workflow meets the criteria above, and just before it is about to complete. Just curious...why are you trying to avoid persistence for the last time, before a workflow completes Bayer If there is a persistence service registered with the runtime the runtime will call WorkflowPersistenceService.SaveWorkflowInstanceState when a workflow instance completes or terminates. This doesn't mean ...Show All

• David_P9 AudioVideoPlayback problems in C#. Audio, no video.

  I am using Microsoft.DirextX.AudioVideoPlayback in a C# application. I believe I am using the Direct X 9.0c August 2005 version. When I play a movie I hear the sound but I do not see the movie. If I move the form I see a ghost image of the movie behind the form but that is it. The C# code is pretty straight forward and simple so I am not sure what it can be. I tried a ".WMV" file and a ".AVI" file, both of which do the same thing. I can play both files just fine in WIndows Media Player. The code follows. Anyone have any idea string path = GetVideoRoot(); if (video != null) {video.Dispose(); } if (File.Exists(path + videoPath)) { lastVideoName = videoPath; ...Show All

• sybaselu Vista Released - so is WWF now complete ?

  Hello Now that Vista is released (I have donwloaded and installed Vista Ulitimate from MSDN) can we presume that we now have the Full release version of WWF runtime now If not how do we presume that our Vista clients will have the full consistent runtime. If we do now have Release 1 WWS, It is still not obvious that there is muchin the way of WCF to WWF integration. The integration between these two Vista .NET 3.0) Technologies still seems weak. We still seem to be stuck with ASMX based web services, and little in the way of WCF. BTW any one know of when we get VS2007, to tidy up all the add ons we need to VS2005 these days Jules Jules, Yes, WF 1.0 has RTM'ed alongside the rest of . ...Show All

• merwy Specifying privilege level for dynamically loaded assemblies.

  I have an EXE application and its assembly manifest has requestedExecutionLevel set to "asInvoker". This exe loads a managed DLL, which performs File IO operations in the ProgramFiles folder. I have created a assembly manifest for this DLL and set the requestedExecutionLevel to "requireAdministrator". So my assumption is that when this DLL is loaded by the EXE and the code to perform file IO executes, Vista's UAC should present the user with an elevation prompt. But this does not happen and the file IO fails. Any suggestions Am I missing something fundamental Is it possible to have a dynamically loaded assembly to perform file IO without having to change the privilege associated with the EXE Thanks & Regards, Vi ...Show All

• Pockey DirectX.AudioVideoPlayback problem

  Hi! I have a problem. I created a Microsoft.DirectX.AudioVideoPlayback.Video object and I added for it an Ending event handler. If I set its Audio.Volume property, after playing the video it does not arrive the handler procedure. If I don't set that property, everything is gone. Why _video = new Video (path); _video.Audio.Volume = -1000; _video.Ending += new EventHandler (_video_Ending); _video.Play(); Sorry for the late reply. You need to set the _video.Audio.Ending to the same eventhandler as the _video.Ending But be carefull because every call to Video.Audio leaks memory [moving to DirectShow forum] ...Show All

• vcbugreporter VNC and Session 0 Isolation

  Hello, I am the author of Bozteck VNCScan Enterprise Network Manager . I am a bit concerned about the new session 0 isolation in Vista. When VNC is installed to a Vista computer as a service, it is locked into running at only session 0 and that is pretty much useless for what it is designed to accomplish. In session 0, you can not remote control the computer or even get a remote screen shot of it. Our software is relied upon by over 100,000 Network Administrators across the globe and I have heard many of them voice deep concern about moving to the new Vista platform if VNC will no longer work properly. RDP is not an option because it does not allow the end user to interact with or view what the remote administrator is doing on their PC ...Show All

• Ed.Richard why the vista XPSDRV printer sample can not print? the result has 0 bytes.

  I install the vista system, and WDK. Then build the print sample (XPSDrv Sample) and install this printer. But when I use this printer to print a sapmle document (such as a notepad document), the print result file(*.prn) has 0 bytes. In the install folder of WDK(\WinDDK\5384\src\print\XPSDrvSmpl\install),the config file "xdsmpl-PipelineConfig.xml" has lower case "input" and "output" for filter dll's.But it should be upper case as expected by filte pipeline.

• Inferno986 workflow data??

I read a thread in this forum that talk about this issue but without a solution. I don't now if any body had found a solution for this problem because I stuck in it and I want to finish my project. So please if any body can help me in this I will be appreciated because I don't know exactly where the problem is thanks.. The re-hosting sample creates a new code compile unit when you re-open a workflow because there isn't a C# parser to read the file and create the code compile unit need. You can either find a C# parser or serialize the code ...Show All

• pnp transform filter: audio input, video output

  Can someone please give me an example of a transform filter which receives audio as an input and produces a video output (pref in bitmap)   The one i am particularly after is an audio input producing an oscilloscope video output.  But any audio in , video out would suffice.  Would really appreciate it. Well, ha that was you. Those solutions sugested would work.

• JesseD70 How to Serialize individual Ink Strokes?

  Hello, I am just wondering how to serialize individual ink strokes. When I attempt to I catch an exception stating that the Ink.Stroke object is non-serializable. I would love to not have to save the Ink object and serialize the entire thing, but instead simple grab a single stroke and serialize it. Does anyone have any information that may help with this Thanks again! Thanks for the code. I tried using the GetPacketData() method above, but TabeltPropertyDescriptionCollection is also a non serializable object.

• rchokler UI.Automation and IE7

  I am trying to understand to what extent I can automate a web app using UI.Automation and IE7. I was expecting to be able to interact with the page however all I see in UISpy are the items like the Status Bar and the favorites etc. Am I missing something obvious Any pointers appreciated. Thanks, -jim Thanks, are there plans to improve the IE support Cheers, -jim I'm afraid I can't provide any useful information about the future. Current IE support is based on MSAA, and UI Automation clients are seeing the objects through the fallback MSAA provider. As a result, you don’t see what you’d see from a browser with native UI Automation support. ...Show All
