Thanks Thomas,
Have you link to the msdn? There is also an easy way to prevent popups in VFP but popups are opened (visible) first. Even they are visible a split second it would be better to prevent/close popups before they are visible. In C and VB there is a easy way to do it with SetWindowsHookEx function but it needs callbacks and can't be used with VFP. Maybe that cross-frame have an answer? Also real filtering (as packet filtering) can be done but then I have to interfer to the NDIS (see
http://www.ndis.com/papers/winpktfilter.htm#W2KPktFilterInterface) and it's not my goal at the moment.
>Yup...
Thats true.
>specifics?
F.ex. if you can access its full document model, you shoud have a possibility to prevent popup to be opened. Or maybe the full document model just doesn't support to do it or is it that you can't do it with VFP?
