How do you write a callback function in VB6? I know AddressOf gets you the function gets the address in a Long. But how do I call the function with the memory address? Thanks!

I’m not sure exactly what you’re trying to do.
To invert control, just create the callback function in a class. Then use an instance of the class (an object) to make the callback.
AddressOfis far too complicated and risky to use in this way.AddressOfshould only be used if you need to register callback functions with the Windows API.
