SendMessage?

[Uncontrolable]

Hello,

I'm writing a simple pixel bot for personal use, and was wondering if theres any way to consistently use SendMessage for sending input based on pixels?

I'm trying to do simple stuff like

keybd_event(0x38, 0x45, KEYEVENTF_EXTENDEDKEY | 0, 0);Sleep(15);
keybd_event(0x38, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);

Only I'd like to use SendMessage rather than keybd_event, because I can then do other stuff while the pixelbot is running.
I've tried using this

HWND hWnd = FindWindow(NULL, "World of Warcraft");
    

SendMessage(hWnd, WM_KEYDOWN, VK_SPACE, NULL);
Sleep(1500);
SendMessage(hWnd, WM_KEYUP, VK_SPACE, NULL);

but it works really inconsistently. Today it might work, tomorrow it might not, it changes from time to time when I open WoW.exe

I've come a little closer, and got it to work when I set the handle in SendMessage myself. Is there a smart way for me to find the window handle, because FindWindow doesnt find the right one it seems.

Not sure what language this is... but here is a stackoverflow about how you could lookup the right process by the executable name, or whatever else you want.

It might be worth using PostMessage as opposed to SendMessage; if you're not adverse to using .NET somewhat you can easily find the Window Handle with the Process Class. If not, you can enumerate open handles using C++, but this requires a lot more work.
