Hi, you can create a new desktop object, which avoids Alt + Tab, Ctrl + Alt + Del ..
Code:
hOldThreadDesktop := GetThreadDesktop(GetCurrentThreadId);
hOldInputDesktop := OpenInputDesktop(0, FALSE, DESKTOP_CREATEWINDOW + DESKTOP_SWITCHDESKTOP);
hLockedDesktop := CreateDesktop('LockedDesktop', nil, nil, 0, DESKTOP_CREATEWINDOW + DESKTOP_SWITCHDESKTOP, nil);
SetThreadDesktop(hLockedDesktop);
SwitchDesktop(hLockedDesktop);
..Then run your application within that new desktop ..
Code:
SI.cb := SizeOf(StartupInfo);
SI.lpDesktop := PChar('LockedDesktop');
If CreateProcess(nil, 'YourApp.exe', nil, nil, True, 0, nil, nil, SI, PI) Then
WaitForSingleObject(PI.hProcess, INFINITE);
..And when your app exits, return to 'real' desktop ..
Code:
if hOldInputDesktop <> 0 then SwitchDesktop(hOldInputDesktop);
if hOldThreadDesktop <> 0 then SetThreadDesktop(hOldThreadDesktop);
if hLockedDesktop <> 0 then CloseDesktop(hLockedDesktop);

Have fun!
