• Software Development for Windows Vista About ICaptureGraphBuilder2::RenderStream

  It has five parameters. I am confused at the fifth paramters. It said it pointer to the IBaseFilter interface of a sink filter, such as a renderer or mux filter. If the value is NULL, the method uses a default renderer. Now, I want to use two cameras together, and display them in two different windows, how to define and use the pSink filter I also said that in Windows XP, although the Video Mixing Renderer (VMR) is the default video renderer for IGraphBuilder methods, it is not the default renderer for the RenderStream method. On any platform, the Capture Graph Builder always uses the old Video Renderer filter unless you specify otherwise.  So, how to specify the video renderer Yes. And unless ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Getting XNA apps to run on non-development machines

  This seems to be a common problem, but I've yet to find a real solution. The only thing I've found that works so far is to include a bunch of dlls with XNA applications. What does not work, however, is satisfying the posted requirements: .NET Framework 2.0 XNA Framework DirectX 9.0c (latest update) When a machine satisfies the above requirements, it still cannot run XNA applications (dies when initializing the graphics device). However, any machine with the XNA SDK has no trouble doing so. It's not reasonable to ask people to install C# Express and the XNA SDK (~120MB total) just so they can play my XNA arcade games. Has anyone found a better solution so far I do appreciate the help that this topic has r ...Show All

• Visual Basic Weird DataGridView Adding Data Error

  I'm having a weird problem while using a DataGridView. I'm using a DataGridView to display some information in an list of something called a Flag. Most of the information are String, one column per Data Property. In my program, I've got a button I press to add an element to this list. So it adds a new flag and refreshes the DataGrid and the new Flag appears. Now, here's the problem. If a Flag is added to the list before the DataGrid is first shown, it works fine. BUT, if the list is empty when the DataGrid is shown and I then press the button to add a new flag, I get an IndexOutOfBoundsError when I click on any cell in the DataGrid. It's the most bizarre thing; if I start with a flag in the list before showing the Grid, I can a ...Show All
