Copy a class
At first, it appears that there isn't a way to copy an existing class in VFP. You can subclass itbut there doesn't seem to be any way to copy a class. Well, with the use of the Project Manager it can be accomplished quite quickly with the following steps:
1. Drag the source class from one library to another.
2. Rename the class in the new library.
3. Drag the newly named class back to the original library.
4. Delete the class from the temp library.
Of course, it would be nice if there was a copy button on the right-click menu or somewhere else. But heck, we can't have everything!
