VFP 5.0 works fine on Citrix WinFrame (NT 3.51), and VFP 6.0 works on NT Terminal Server 4.0/MetaFrame. VFP isn't recommended for those environments because of the form engine. It does work, but it is much slower than VB, etc.

It's because Citrix/TS grab each hWnd on a form and transmit only the information to recreate it on the client, which is much faster. VFP uses 'bitmapped' forms that have to be transmitted pixel by pixel, like PC Anywhere. Even with the client side cache it's slower than PC Anywhere I found.

VB,VC++ native controls each have a Hwnd of their own, which is intercepted and transmitted. Only graphics in pushbuttons and backgrounds are sent over as bitmaps. And since those get cached, performance is acceptable even over dialup.

IOW, if you use a VFP app, make sure your clients are using Cable Modems or another high bandwith solution to keep the speed tolerable.

HTH,
