Take a look at this article:

You may have problems if the hidden window is disabled.

Hello Forum,

I want to use another program. It should be started hidden, some
inputs must be given and than a textbox be read.

I have get the hWnd with the help of GetWindowThreadProcessId().
If I send VK_RETURN with PostMessage(). The default button on the
foreign window would be pressed: PostMessage(hwnd, WM_KEYDOWN,
VK_RETURN, 0);
This means: I have found the right hWnd.

My next idea was to send a VK_TAB or VK_DOWN to switch between the
controls:
PostMessage(hwnd, WM_KEYDOWN, VK_DOWN, 0);

But both dont work. Why? What I must do instead? (SendMessage()
doesent work too, it only executes the msg immediately...)

OR:

I think that this problem is solved a lot of times. Can someone show
my an example source? Or tell me what the keywords are? "Control
another program C Source" doese not find proper entries in Google...

Thanks for the help

Peter
