>Is there a way that I can use the command modify form in a compiled application? My purpose is I will compile my exe. That will run and modfy my form in that exe and not in my vfp. When I try to do that Feature is not available error message appear.
"Feature not available" usually means it was disabled on purpose. The idea is that you need a VFP license to modify forms, for example. Note that for the copy you distribute to the client, no license is required, so you can't expect them to receive the complete VFP development capabilities.
As to workarounds, you might try to add items to the form dynamically, with AddObject(). The related data might be stored in tables. What you don't get (for the end-user) is the interactive environment.
