Your post really doesn''t say anything useful... could you post your initialization code (where you parse the command line) and primariliy, is the handle of the window you''re passing to the screesaver a valid one?

encom:

First off, I''m going to assume that when you say "/p hwnd" you''re meaning that you''re passing the (numerical) handle to a window, not the string "hwnd".

Next, as I understand it and have used it, the preview window handle that is passed in is a handle to an already existing window, which means that you don''t have to register it, create it or do anything with it. All you need to do is render into the window and it takes care of the rest. Also make sure that you don''t try to destroy the window when your program exits.

If you''re already doing both of these suggestions, try posting the code you''re using dealing with the window. It''s hard to help without knowing exactly what you''re doing. Good luck.

Glad you''ve got it working. When you say that when you don''t register and create the window, it doesn''t work, you''re referring to the preview mode there, right? Not the regular mode? I don''t have the code of my most recent screensaver with me right now, otherwise I''d check, but I think that the window handle that is passed in should just be the handle to the small preview window (in the preferences dialog), which means that it''s already created and ready to go.

Oh well, if it works and works well, then good job.
