Hello,

how can I determine the visible hight and width of the
taskbar and where the taskbar is docked (top, right, left,
bottom) using plain C (WinAPI)?
And how can I determine whether the taskbar has the auto-hide
feature enabled?

Thomas

It's a window, so you can get a handle and then use GetWindowRect:


//
--------------------------------------------------------------------
// PFWTaskBarFind
inline HWND PFWTaskBarFind( void )
{
#ifdef UNDER_CE
// Look for Smartphone version first, in case other is around
(paranoia?)
HWND hwnd = ::FindWindow( _T( "Tray" ), NULL ); // Smartphone
if (!PFWHwndCheck( hwnd ))
{
// Eric R. Balch (microsoft.public.vc.vcce 15 Jan 99) says
next line works for CE.
// BZ found it works for Pocket PC, old Microsoft Windows CE
platforms, and generic CE
hwnd = ::FindWindow( _T( "HHTaskBar" ), NULL );
}
return hwnd;
#else
// "Big" Windows
// (thanks to Shing Yip, comp.os.ms-windows.programmer.win32, 21
Jul 99)
return ::FindWindow( _T( "Shell_TrayWnd" ), NULL );
#endif
} // PFWTaskBarFind
//
--------------------------------------------------------------------
// PFWTaskBarGetHeight
int PFWTaskBarGetHeight( void )
{
HWND hW = PFWTaskBarFind();

if (!PFWIsVisible( hW ))
return 0;

RECT rW;
::GetWindowRect( hW, &rW );

return (rW.bottom - rW.top);

I can't help with this.
