I need to know size and position of all windows that the user can see.

[webJose]

Use EnumWindows().

And search for what? I remember trying this once, but I had problems obtaining only the ones I needed.

Thanks

What do you mean "what"?? Your question is clearly answered by EnumWindows(). "How can I get to know the size and position of all windows visible?" That is your question, is it not?

Well, then the answer is "Use EnumWindows() to obtain a window handle of all top-level windows. In case you don't know, you can use the handle to obtain the size and position of the window.".

If I'm wrong, then I'm clearly forgetting English.
