>sends messages to each of your defined windows telling them how offten to refresh,colors etc.. A API that I'm working with sends a message to the VFP open window and I don't know how to capture it. Here is what the API vendor told me:

You're going to need to write code in either VB or C to hook the Windows event loop for these two messages as a part of an ActiveX control, and have them generate events that you can then hook with VFP code using VFPCOM, or write an FLL to tie C code directly to VFP. I believe there may be an example of such written by Christof Lange three or fours years ago; if you don't know C and are familiar with VB, creating a VB ActiveX control is probablyu easier, and some of the techniques you need are cover in Dan Appleman's first book on the Win32API and VB, available in many bookstores, or through sources like amazon or barnesandnoble
