The standard way to minimize all windows is to left click on the taskbar, then from the pop-up menu to choose Minimize All Windows and finally to close the pop-up menu. How can I do this by code?

 

1.

  Start a new project using File | New Application.

 

2.

  Add a Button. Edit its OnClick event:

 

void __fastcall TForm1::Button1Click(TObject *Sender)

{

    keybd_event(VK_LWIN, 0, 0, 0);

    keybd_event('M', 0, 0, 0);

    keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0);

}

 

The Win32 API function keybd_event allows you to send keys to another application.
