Q:
How can I determine the size of the windows taskbar with Delphi 4?
A:
There are several ways to obtain this information:
look at SystemParametersInfo and the SPI_GETWORKAREA index
use Screen.DesktopHeight, Screen.DesktopWidth properties
call
SHAppBarMessage(ABM_GETTASKBARPOS, pabd);
and then read the APPBARDATA structure for the Height and Width.
