It's helpful to call the Dispose () method on large objects (like bitmaps) that your program no longer needs. This allows .NET to use memory more efficiently. Also see the standard dispose pattern. Here's a good discussion of it: http://www.codeproject.com/KB/dotnet/idisposable.aspx[^]

its possible, but you have to ensure threadsafety, say, by using a circular buffer or similiar. Hope this helps, Good luck

No. coz last time when another function returned this same negative value (-214...), the problem was not in that function itself. And BTW i wrote "ICaptureGraphBuilder2 capGraph;", its not actually like that(coz the code was bit lengthy so included that method only). i just wanted to tell that capGraph is actully its object.Anyways thx for the reply.
