{
At times, it is necessary to get a handle (HWND) to the shell's main window.
MSDN offers us next method:
hwndShell := FindWindow('Progman', nil);
It seems to be a simple code but I've found much better solution.
The User32.dll has one more useful and of course
undocumented function - GetShellWindow!
}
// This example will show you how you can obtain a handle to the
// Windows Shell window without calling the FindWindow function.

// This function returns a handle to the Windows Shell window
function ShellWindow: HWND;
type
TGetShellWindow = function(): HWND; stdcall;
var
hUser32: THandle;
GetShellWindow: TGetShellWindow;
begin
Result := 0;
hUser32 := GetModuleHandle('user32.dll');
if (hUser32 > 0) then
begin
@GetShellWindow := GetProcAddress(hUser32, 'GetShellWindow');
if Assigned(GetShellWindow) then
begin
Result := GetShellWindow;
end;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
hShellWindow: Hwnd;
strWinText: array[0..260] of char;
begin
hShellWindow := ShellWindow;
if hShellWindow <> 0 then
begin
GetWindowText(ShellWindow, strWinText, 255);
ShowMessage(strWinText);
end;
end;
