How to send input to cmd when cmd is running as administrator?

问题

I created an application that sends keyboard input to cmd.exe. This works when running cmd as a normal user but fails when cmd is run as Administrator.

This is my code:

Var
   Wnd:hwnd;
begin
   wnd:=FindWindow('ConsoleWindowClass',0);
   if wnd <> 0 then
    begin
      setforegroundWindow(wnd);
      keybd_event(Ord('A'),0,0,0);
    end;
end;

Notice that ConsoleWindowClass is the class name of cmd.

How can I send input to cmd when cmd is running as administrator?

How can I type with this code inside cmd when cmd is runing as administrator?

You cannot. This behaviour is by design. The cmd process runs with a higher integrity level than your process. Your only way to overcome this is to arrange that the process that fakes input also runs as administrator.

Finally found that if we run the base application as admin and then try to send an input to cmd it works fine.
