• Dave Koehler Building with Vista Platform SDK and Visual Studio 2005

  What is the intended "strategy" the Vista Platform SDK has for how projects designed under Visual Studio 2005 should be built in conjunction with the Platform SDK If it was supposed to be obvious from the documentation, I guess I'm still missing it. For a makefile-based project or sample, things still seem obvious and/or unchanged. Between SetEnv.cmd and Win32.mak a bunch of appropriate decisions regarding pre-processor definitions like WINVER and APPVER, default libraries, and the include and lib paths appropriate for the build mode that was selected, etc., are established. The VCIntegrate.exe "integration" seems to be nothing more than setting the include, lib and path directories via .config files updated unde ...Show All

• DroopyMsdn design time dialogs within custom activities, architecture

  Hello WF, I need to write several custom activities that can be placed on a state machine workflow. These activities will have two aspects: design time -- pop up a dialog to allow user configuration, and run time -- execute the configured action. Examples: (1) security activity . design-time: select roles & actors (from our security subsystem) that will be given chosen rights when a state is entered and exited run-time: executes the transfer of rights according to what was configured (2) signature policy activity . design-time: pop up a dialog to choose a signature policy that applies to a transition from one state to another. run-time: enforce the validity of the signature policy.  signature policies come from our database.

• Colmeister How to render 2 video streams using EVR?

  By now my app can just play 1 stream using EVR. The usage is similar with using Windowless VMR9 filter. I have read "Writing Custom Mixers and Presenters" on Vista Platform SDK Doc many times and search the relative topics using google. But I can't find out much information, specially about how to render 2 streams. Who knows how to write a custom mixer, which interfaces should be called and their steps. Or tell me where has some materials on this knowledge Thanks Microsoft Guys!! As soon as I'll have some time, I'll try to update the MultiVRM9 sample to make a MultiEVR. But before, it's time for questions: Regarding the CLSID_MFVideoMixer9, where can we find interface description and how to use it Do yo ...Show All

• jv_getmore Redirect

  Hi! Scenario : ASP .NET app with Sequential WF as Controller. Everything works fine until there is a redirect to a suppliers site. The workflow is waiting on a HandleExternalEvent activity. We supply our URL in the query string and the supplier redirects back to us once the user has finished the order. When our page loads from this redirect, we wanted to raise the event that the workflow is waiting on, in order to proceed but no go. The event gets fired, but the workflow does not execute. It seems to me that its becuase the aspnet thread exits and cannot execute the workflow. Of course after page load if we click a button to fire the event everything works fine, but of course that is not allowed in this scenario. So is there a ...Show All

• Preston M. Price Can I dehydrate the Workflow object as well as the instance?

  Hiya All Can I dehydrate the workflow object (i.e. not an instanciation of it) into SQLServer I want to save all versions created of a workflow so that I can chose to instanciate the workflow from any of the previous versions if I need to. This is due to a compliancy issue - being able to reconstruct the data created by a previous version of a workflow to prove accuracy. Thanks Michelle x Hi Matt! Your technique works perfectly! I created a slightly different implementation, but the concept is the same. Again, many thanks for your solution. It solved the last problem I was having with the workflow implementation.   The versioning issue is my last big problem handling workf ...Show All

• Sudhakar.hcitek WorkflowRuntime drastically slows down application?

  I have these two simple test methods: public void TestRuntime() { this.Cycle(); //takes 30ms WorkflowRuntime wr = new WorkflowRuntime(); wr.StartRuntime(); this.Cycle(); //takes 5500ms } public void Cycle() { for (int i = 0; i < 100; i++) { Trace.WriteLine(i); } } When I start TestRuntime(), the first call to Cycle() takes about 30ms, but the second call (after runtime start) takes above 5000ms. Subsequent calls to Cycle() take between 3000 - 8000ms. Is this usual behaviour or I am doing something wrong (There are no running workflow instances.) This is not normal behavior, in fact when I try the similar code the ...Show All

• j238 WebCam Pan/Tilt with VB.NET

  I am trying to figure out how to control the Pan/Tilt of a Creative Live! Motion webcam. I have seen some posts which talk about the Platform SDK (which I have downloaded) and then say to look at the GraphEdit program. I'm sorry, but I can't figure out how that helps with determining the objects/API calls needed to control the WebCam as required. Has anybody actually tried to control the Pan/Tilt of these webcams and if so, give me some pointers on where to start. I can't find any DirectShow namespace when reference the DirectX libraries in VS2005. Where do I find it (if in fact, I need it) Thanks Well, I would guess that the IAMCameraControl interface is the one you need. Assuming your specific camera ...Show All

• kenneth123 Copy-Protection, License-Enforcement, DRM and VISTA

  I am a developer in a small company that develops DRM, copy-protection and license enforcement tools for Windows developers. Our tools currently allow the client to create licenses and integrate our run-time components into their software to enforce a variety of license models. Many of the mechanisms that provide this functionality, such as hiding redundant copies of the license in hidden and inconspicuous locations on the system and the registry are simply not going to work on Vista. Many operations the run-time performs to detect hackers will require permissions not likely to be present by default and naturally a hacker will refuse to allow. We are willing to redesign and adapt (we must - or we will die). My question is - what ...Show All

• PiGuy Where is the >detailed< Vista Software Logo Spec documentation?!

  I've been looking for months to find more information about the Windows Vista Software Logo program, and have basically come up with nothing... Is anyone else having this issue There seems to be only one document available called: "Windows Vista Software Logo Spec 1.0.doc". However, this document can barely be called an outline of what really should be available. If you look at the DFW XP and DFW XP x64 counterpart program on the http://www.microsoft.com/winlogo site, you will find an overwhelming amount of information including test framework docs and in-depth technical requirements docs for engineers, totaling well over 400 pages of highly detailed information. But for Vista we only get 24 pages ! So much has changed between X ...Show All

• SoccerDude Error accessing the OLE registry (Build 5744 and msrdp.ocx)

  Getting an error trying to register the msrdp.ocx control on Vista RC2. Using regsvr32 it apparently "succeeds" however programs that use the control report it as not registered correctly. Using innosetup to do the installation gives the error: Error accessing the OLE Registry. Error 0x8002801C. That indicates a permissions error typically. Any idea why this Microsoft control will not register Using the version from Windows Server 2003 SP1. Is there a new version of the control that works correctly on Vista I guess you are running with UAC enabled so all registry access to HKEY_LOCAL_MACHINE is redirected without the caller noting it. So I guess the registration was never written to the correct place and hence the COM cl ...Show All

• MadMojo1 Automatic conversion of workflow type to XAML

  Hi, Is there any tool available for converting a workflow type to XAML format Regards, Chakri. Daniel, I think this is not what the initial poster is asking, this is serializing a workflow instance, not the workflow definition. I posted a similar question a while back and got no answer. The problem I have is that we started developing a code based workflow and would now like to convert it to XAML with code behind but apparently we're stuck with our initial choice and it's now too much work manually convert the workflow to XAML. -- Nuno I saw a method named Serialize in WorkflowMarkupSerializer class with the following description.
