Hi,
I'm new to AHK and I have a question:
How can I do to simply center a button on a GUI?
I've search the internet but found nothing simple (or it's me )

There is some conditions:
-I don't know the size of the gui
-The GUI is not resizable
-The button have a fix width, height

Thanks in advance.

If you have a portable AHK this is not working... Too bad, can't test it.
