Hacker’s Guide to Visual FoxPro
An irreverent look at how Visual FoxPro really works. Tells you the inside scoop on every command, function, property, event and method of Visual FoxPro.
FileClass, FileClassLibrary
These properties indicate the name of the class on which a form is based and the class library containing that class. They apply to File objects.
Usage
cClass = filFile.FileClass
cClassLib = filFile.FileClassLibrary
Forms contain information about their class and class library in the Class and ClassLibrary properties. (Big surprise.) But that information is available only when the form is open. When you’re working on a project and want to know the provenance of its forms, use FileClass and FileClassLibrary. (Seems to us this is most useful for documentation tools.)
These properties contain the empty string for files other than screens.
Example
FOR EACH oFile IN oProj.Files
IF NOT EMPTY(oFile.FileClass)
?oFile.Name + " is based on class: " + oFile.FileClass + ;
" from classlib: " + oFile.FileClassLibrary
