That would require a callback. Look into DllCallbackRegister.

I've recently written some AI for a game written in AutoIt. For speed purposes, the AI is written in C++. One method to communicate with the C++ was to FileWrite(), wait for the contents to change, and then FileRead(). This works well, since while AutoIt is sleeping (waiting for the file contents to change), the GUI still functions (it's OnEvent).

Today, I decided to write the AI into a DLL (I feel it's much more elegant). However, I now run into the problem that AutoIt completely stops while waiting for the DLLCall to return. The GUI is completely functionless during this period: input boxes do not accept input, the window cannot be moved or resized, buttons do not glow on hover, etc.

My question is: is there any way to wait for the DLLCall to return in the background?

I think a callback approach would not be so helpfull, and anyway not needed. Your original approach worked so I think you should simply reproduce the approach with messages. Before you waited for a file to be created so you could send a message from the AutoIt Script (A) to the C++ program © to say "Info X wanted", C replies with "OK will do" straight away so that A is idle again, then when the info is ready C sends A a message saying "here is the info".
