Does anybody have an idea how do do it? By avaible area I mean coordinates (a RECT?) of the desktop area without the taskbar.

Thanks, but it didn't give me a proper result (return value was 553 while my taskbar "begins" at 570 Smile

) So there was empty space beetwen my window and the taskbar. But I found another solution: SystemParametersInfo + SPI_GETWORKAREA, and it works just fine.

No, they return screen resolution, not the workarea size. And with SystemParametersInfo I can even handle the cases when user has his taskbar on top of the screen Smile

Here is the documentation (excerpts actually) in win32.hlp under GetSystemMetrics:

Quote:

SM_CXFULLSCREEN, SM_CYFULLSCREEN
Width and height of the client area for a full-screen window. To get the coordinates of the portion of the screen not obscured by the tray, call the SystemParametersInfo function with the SPI_GETWORKAREA value.

SM_CXMAXIMIZED, SM_CYMAXIMIZED
Default dimensions, in pixels, of a maximized top-level window.

SM_CXSCREEN, SM_CYSCREEN
Width and height, in pixels, of the screen.

And here's some parts from the SystemParametersInfo section:

Quote:

SPI_GETWORKAREA
Retrieves the size of the working area. The working area is the portion of the screen not obscured by the tray. The pvParam parameter must point to the RECT structure that receives the coordinates of the working area.

So all in all, SPI_GETWORKAREA is what I need.
