ActiveX controls in VFP
Title:
OCX96 specification and VFP container
Just a quote from pretty old article
"The main advantage of OCX96 controls is their performance. They retain all the advantages of regular OLE controls. However, being able to activate without a window means they're generally faster than their window-based counterparts.
The biggest drawback to OCX96 controls is that very few containers currently support them. This situation is likely to change as the next generation of Microsoft control containers ship."
Could anyone shed some light what's difference between VB container and VFP container in treating ActiveX which are compliant to OCX96 specification.
Perfomance seems to be noticeably worse in VFP than in VB. For instance properties "DoubleBuffering" and "SmoothExpand" for one of the controls I use instead of eliminating flickering on fast computers just add some flickering and make control unbearably slow on slow computers.
Control creators assert from debugging that VFP container behaves slightly diffently and not completely compliant; maybe for the sake of better treatment of native controls.
Thank you
Michael
