Hi, Guys,

Does somebody know how to get the height of the taskbar using BCB? Because I 
need to arrange a few windows on window screen, need to calculate the 
window's height to void overlapping taskbar. which function can call to get 
the height of the taskbar?

Thanks  a lot.

    APPBARDATA abd = {sizeof(APPBARDATA), 0};
    abd.hWnd = FindWindow("Shell_TrayWnd", NULL);

    if( SHAppBarMessage(ABM_GETTASKBARPOS, &abd) )
        // use abd.rc as needed ...

Alternatively:

    RECT r = {0};
    HWND hWnd = FindWindow("Shell_TrayWnd", NULL);
    GetWindowRect(hWnd);
    // use r as needed ...

You are not taking into account that the Taskbar can be on the side of the
screen instead of the top or bottom, or that the Taskbar can be hidden when
not used.  You should instead be using SystemParametersInfo() to get the
work area of the desktop.  Then you don't have to care about the Taskbar at
all.  For example:

    RECT r = {0};
    if( SystemParametersInfo(SPI_GETWORKAREA, 0, &r, 0) )
    {
        // position the windows within the bounds of the RECT as needed ...
    }
