• TheDevilsJoker Accessing Database from Property designers

  I am writing custom activities that have custom property designers. The property designers need access to the database in order to allow the users to configure the activity correctly. The long term goal is to rehost the Designer, but in the interum, we need to be able to do this in VS.

  I am working off DesignerHostingSample of Lab 10 (Netfx 3). I have added my own tracking service called WorkflowFileTrackingService derived from TrackingService and added to workflowruntime.

• PublicError Winhelp on Windows Vista

  Hi, Does anyone know if the user downloadable winhelp engine be available for the Vista Launch date Hi Tony, All the work I did about two months ago trying to track down info on winhlp pretty much hit a dead end. The responses I recieved is that release dates were not available for this product. I wish I had a better answer for you. As for redistributing the file, that would be included in the user agreement when you obtain the file. I know it will be a lot of work initially, but I would recommend making the transition to html based help. Winhlp is being shutdown so chances are you will have problems with it. have looked for the winhlp32.exe help file to download.......... ...Show All

• Melterx12 sink filter handling and Dump filter problems

  I am trying to write a filter that handles raw sample data in a very specific way..... Easy. take the dump filter from the directshow samples, modify it to handle the data in the way I want, instead of writing to a file, and thats' it. Well, NO. At first I thought it was a problem with my code, as the samples my application was handling had nothing to do with what it should be handling, but then I resorted to testing the original dump filter itself. I compared two filter graphs, one with its last output pin hooked into the "file writer" filter, which also does absolutely no formatting and writes raw data. The other with the dump filter. I got two completely different files (in one of the attempts I wrote an avi file...the filewr ...Show All

• pmarreddy How receive the message WM_DWMWINDOWMAXIMIZEDCHANGE?

  Hello, how it is possible to register and then get the message WM_DWMWINDOWMAXIMIZEDCHANGE On http://blogs.msdn.com/greg_schechter/archive/2006/09/14/753605.aspx I have found this information: WM_DWMWINDOWMAXIMIZEDCHANGE - windows can register to hear about when other windows have been maximized. This is useful for, for instance, the TaskBar or the SideBar which go opaque when other windows get maximized. The following code will not detect the message WM_DWMWINDOWMAXIMIZEDCHANGE but the other messages like WM_DWMCOLORIZATIONCOLORCHANGED will be detected. c++ code LRESULT CALLBACK wndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { switch(message) { case WM_DWMWINDOWMAXIMIZEDCHANGE: /* messa ...Show All

• Salman Maredia Hosting WorkflowService (WorkflowRuntime) in IIS using WCF

  Hi, I'd like to host some kind workflow service (using Windows Workflow Foundation) within the IIS. Therefore I have configured a service file (.svc) and an appropriate web.config file. When the service starts (managed by IIS ) it should load the WorkflowRuntime instance. Therefore I've created a class implementing the IExtension<ServiceHostBase> interface holding that instance. Because my application is not directly responsible for creating the ServiceHost (-> IIS) - how can I add this extension to the service host Is it possible to configure this via the web.config file (<extensions>-Element) Or do I have to write such a class inheriting from ServiceHostFactoryBase and configuring the service file Thank you! ...Show All

• Manas Correct way to create a State Machine

  Hi I am trying to create a statefull booking service (state machine workflow exposed as webservice). It has the following states. Created, TicketSelected, Pay, Comfirmed. My question is twofold.

I've read about auditing / non-auditing IP, which do or do not encrypt the security token for the RP, but I was wondering, is it only up to the IP to encrypt or not the token I mean, does the RP has a way to say "hey, don't encrypt the security token when you send it to me" For example, with some kind of tag on the web page in the <object> tag (like "requiredClaims") or in some XML config file Thanks, Thanks Caleb, that was the info I was looking for. for a browser based scena ...Show All
