Can not simulate Win+D on Metro UI in Windows 8?

Question

I want to switch Metro UI to desktop. Simulate Win+D can work on traditional desktop, but can not work on Metro UI. Code as below:

  keybd_event(VK_LWIN, MapVirtualKeyEx(VK_LWIN,0,GetKeyboardLayout(0)),  0, 0);
    Sleep(30);
    keybd_event(VK_D  ,MapVirtualKeyEx(VK_D,0,GetKeyboardLayout(0)) ,  0, 0);
    Sleep(30);

    keybd_event(VK_D , MapVirtualKeyEx(VK_D,0,GetKeyboardLayout(0)) ,   KEYEVENTF_KEYUP,0);
    Sleep(30);
    keybd_event(VK_LWIN, MapVirtualKeyEx(VK_LWIN,0,GetKeyboardLayout(0)), KEYEVENTF_KEYUP,0);

Win+C can work well. Please tell me why it can not work well.

Hi,

Welcome to the MSDN forum.

Based on your description, your issue is about Metro API, so I’d like to move this thread to Building Metro style apps with C++ for better support, since here is for C++ general.

Thanks for your understanding.

Regards,

Locking this as a duplicate of  Can not simulate Win+D on Metro UI in Windows 8? in the Application Compatibility for Windows Desktop Development Forum.

Since the question is about writing a desktop app it is off topic in the Building Metro style apps with C++ forum.
