Hello

I have 2 questions:

1) I am trying to use ClipCursor() function.
As the test  I just call GetClipCursor(&clip_rect) and then right away I 
call ClipCursor(&clip_rect).
When I start dragging a dialog box I can drag it under the desktop taskbar. 
Why?

2) Then I am trying to change the clip_rect, to decrease it by the taskbar?
I get the desktop window and then desktop rectangle. It turned out that 
desktop rectangle equals to clip_rect.
desktop_hwnd = GetDesktopWindow();
GetWindowRect(desktop_hwnd, &desktop_rect);

I get:
 clip_rect = = desktop_rect

How do I get desktop rectangle minus taskbar?

Thank you
Rony.

Obviously, GetClipRect() is including the area occupied by the taskbar.

Why don't you want the user to be able to reach the taskbar?

You are retrieving the rect of the desktop window itself.  The taskbar sits 
on top of that.  So it makes sense for the desktop rect to include the 
taskbar rect in it.

Have you looked at SystemParametersInfo(SPI_GETWORKAREA) yet?

Thank you very much!
SystemParametersInfo(SPI_GETWORKAREA) is what I needed.
