Process name from ID?

[ExSanity]

I'm trying to get a process name from (what i think) is the PID i get

		HWND Tabbed = GetForegroundWindow();
		printf("Open Window!: %d", Tabbed);

The code above outputs numbers instead of Notepad or Console or what ever when i want it to say Notepad or the actual name of the process

To get the PID from a HWND use GetWindowThreadProcessId.

Then you can create a snapshot of system processes and iterate over them, comparing the PID returned above.
