• Visual Studio Official VSL feedback and suggestions thread

  The Visual Studio Library (VSL) is a new addition to the Visual Studio SDK 2005-10 (VS SDK), and was not previously available in the VSIP SDK.   VSL is a C++ source library, primarily targeting the Visual Studio Platform, which extends the Active Template Library (ATL).  A Power Point presentation given at the VSIP dev lab can be be found here .   Thus far the contents of VSL have been solely driven by the needs of the four new C++ reference samples included in the VS SDK, so many classes are not as fully featured as is possible.   Content will continue to be added to VSL, as needed by the C++ samples; howeve ...Show All

• Visual C# GDI form transparency problem

  I'm trying to draw a transparent form using GDI, by overiding the OnPaint and OnPaintBackground event handlers. This technique works well enough on the first draw,and it produces a nice result, however, on subsequent draws, it works less spectacularly. For some reason, the screen is never cleared, and when it redraws the new things are composited ontop the previous draws, making the transparent images darker and darker. Here is the contents of protected override void OnPaint(PaintEventArgs e) { Graphics g = null; Assembly assembly = Assembly.GetExecutingAssembly(); Point point = new Point(400,400); backBuffer ...Show All

• Software Development for Windows Vista Host Workflow in Windows Service

  Is it possible to host workflow in windowsService if possible how John, Tomas Restrepo has also created some nice Msmq workflow activities. You can just drag and drop a Msmq Receive message activity in your workflow. http://www.winterdom.com/weblog/2006/10/20/MsmqActivitiesV11Released.aspx The part that I'm not too sure about is how to have multiple worklow instances processing messages from the queue. It's easy to start multiple workflow instances (and wrap the msmqReceive in a while loop ) Once the queue is empty the workflow should 'sleep' till the next message arrives Is that possible I wonder if the ...Show All

• Visual Basic Can i sell what i make

  can i sell what i make with visual basic 2005 beta 2 App will not be time restricted but the IDE will stop working I think. Also, the license says that the end user has to obtain the target from Microsoft which means that the .NET Framework Beta 2 may expire which means that your app also does not work. A good idea would be to change the date on ur machine to May 1th 2006 and see what happens - that will eliminate all questions :) In case you do not want to try on ur dev machine, install Virtual PC and try on that: http://www.microsoft.com/windows/virtualpc/default.mspx Regards, Vikram ...Show All

• Software Development for Windows Vista Tracking and Monitoring of dynamically updated workflows

  I am working on an application that dynamically updates a workflow and adds activities at runtime. Now I tried to track those workflows and wanted to view them with the Workflow Monitor. The bad thing about that is, that the sqlTrackingWorkflowInstance.WorkflowDefinition throws as NullReferenceException as it is not able to build the dynamic workflow. All activity events of the added activities have been tracked correctly, but I can't build the WorkflowDefinition. Is there any way to construct and display the workflow as it executed in the runtime with all the dynamically added activities Thanks for any answer. ...Show All
