c++: How to send keys to child process

jeudi 19 mars 2015

I am trying to send keys such as F4 F1 F2 or Enter to child process without type in keyboard.

I'm trying to use PostThreadMessageW But it not work.


PostThreadMessageW(pi.dwThreadId, (UINT)WM_KEYDOWN, VK_NUMPAD0, 1);
PostThreadMessageW(pi.dwThreadId, (UINT)WM_KEYDOWN, VK_RETURN, 1);

my child process run console app that just wait some input then close


printf("Child Process");
getch();

Before i post message this process isn't close.

Have anyway to send keypress to Child process.

Or I'm doing something wrong?
