When you add a dBASE screen to a Visual FoxPro project and modify it, you are presented with two conversion options:
In a visual conversion, the objects on the dBASE screen are converted into Visual FoxPro objects on a new form. The Converter sets basic properties for the objects, such as size and placement, but does not attempt to apply event or method code to the objects.
Code associated with the screen is placed in a .prg file with a name you assign. Use a visual conversion when you want to write new code to make the form work, taking advantage of features of the new Visual FoxPro object model.
If you use the full conversion option, your screen will function immediately as a FoxPro 2.x/dBASE READ-compatible form. For more information about working with converted forms, see Converting FoxPro 2.6 Screens.
For more information, see the section, "Adding Controls to a Form," in Chapter 8, Managing Data Through Forms, in the User’s Guide.
