More information:
This application implements a proprietary callback scheme using two Interfaces defined within VB. It includes a sample application in which the Interfaces are implemented. The app allows you to add listeners and notify them of events at run time. Detailed documentation is included.

If you've never used the Implements keyword or developed an Interface in VB, you might want to download this code to see how it is done.

To get it to work, you will have to add Project1.vbp and notifystruct.vbp to the same Project Group, then add a reference to notiftystruct in Project1.
