Hello,
I'm working on a small automation solution. I want to emulate
Keystrokes from an application including shift and alt key.
h = FindWindow (NULL, argv[1]);
if (h != NULL)
{
hed = FindWindowEx (h,0,"edit",0);
SendMessage (hed, WM_CHAR, kbchar, 0);
}
or
h = FindWindow (NULL, argv[1]);
if (h != NULL)
{
PostMessage (h, WM_CHAR, kbchar, 0);
}
doesn't do the trick for me. I need to send stuff like "CTRL+P" to an
appliction. Any Ideas how to do that in C? Every help is appreciated .
I think instead of sending WM_CHAR, try sending WM_KEYDOWN
I tryed some other approches, but nothing seems to work on XP.
For example I send a CTRL+P to the Media Player with and without
Focus and also with force to Foreground and without:
SetForegroundWindow(hwnd);
SendMessage(hwnd, WM_KEYDOWN, VK_CONTROL, 0x50);
and
SendNotifyMessage(hwnd, WM_KEYDOWN, VK_CONTROL, 0x50);
and
PostMessage(hwnd, WM_KEYDOWN, VK_CONTROL, 0x50);
The only result I got so far with the Media Player is, I get the app in
the foreground and the app shows that only the control key is pressed without any other additional key. The only working command
is WM_CHAR with PostMessage for apps. Is there any trick to make
it work with Windows XP.
A key press requires a key down as well as a key up. You should use the keybd_event() or SendInput() functions to simulate keyboard usage. To simulate Ctrl+P you need to:
Key down down Ctrl
Key down down P
Key up P
Key up Ctrl
Thanks. keybd_event() works for me.
