MSDN shows the following example for rendering a file in a filter graph:
hr = pGraph->RenderFile(L"C:\\Media\\Example.avi", 0);
my existing code manages movie filenames as LPCTSTR values. I have in place a placeholder method:
DWORD CImageView::LoadMovie(LPCTSTR a_lpszMovieName)
how can I cast my LPCTSTR movie name into something that RenderFile can use? Is that 'L' a macro of some type like _T ?
