According to msdn, when I get a CWnd* with CWnd::FromHandle, The pointer may be temporary and should not be stored for later use. What is meant by "later use" is not clear to me. Is it only the scope of the current method? As far as I know, there is no GC in Win32! ...

I note an applications handle when I use the shell function to open it. I then use that handle to close the application later. However the user can also close that other application himself.

If I don't Clear() and don't draw, then the window is invisible, as it should be. Clear() is the culprit ...

I pinned the issue down to the use of ID2D1HwndRenderTarget::Clear. This function is vital to my application as without it, painting becomes rather... weird. Is there...
