Some ActiveX controls won't work because they require CallBacks, something VB supports. However, I thought I heard that VFP 7 now does support this feature, so you may want to reserve judgement until you try the control with VFP 7. The other problem is supporting "Dual Interfaces". There is actually a SYS() command that allows this to work - check the MS knowledgebase or Help file. one final thing, the AutoYield property should be set to allow events related to the control to happen...
