Using WM_COPYDATA for interprocess communication.

Recommended Posts

colc1

Hi all. I want to have two separate scripts running and when I click a button, (e.g. submit) I want certain information to go from one script to the other. I'm told WM_COPYDATA is the best way to do this but I'm not really sure how to use it. For an example program I'd like to send just one number from one script the the other.

In a real life example I want a GUI to be one script and the other script lets say to be running calculations.

Any help would be greatly appreciated.

colc1,

Welcome to the AutoIt forums.

There are multiple examples on the forum of scripts using WM_COPYDATA to communicate between scripts. Having studied those, what code do you have that does not work as you wish?
