Simulating keyboard presses

[Bligen]

So how do you make the program write a specific line, for example a simple bot that writes "This is a bot message" in a chat every, lets say, 10seconds.... I know how to make the mouse click on the chat position, but I don't know how to make it write the text and then click enter to send the message

EDIT: windows operating system

I think Autohotkey is the software you are looking for, not C++

[Bligen]

So it's not possible to make a c++ program do it?

is it that, what you want:
pseudocode: sendmessage (handle_of_window, WM_CHAR, 'h')
