Hi Nick,

The article you referenced has no info on how to implement API call back functions in VFP.

>For even more details :) see "Visual FoxPro Callback Design" portion of Calvin Hsia's article "Microsoft Visual FoxPro and Advanced COM"

>>VFP doesn't support callback functions. For more details see

>>>Some API's need to receive Call Back functions as parameter, In Visual basic this seems not to be a problem, you use the addressof operator but, how do I do that in VFP7?
