You have to create a class, and implement the ISocketXObjNotify interface. You can do this by dragging the Interface from the Object Browser to your code.

Once you have done this, you will use the EventHandler() function.

For more info see the "implement interfaces" and "IMPLEMENTS" topics in VFP 7.0 help.
