I set up a set of forms, there are two forms, and set up the custom, but in the menu with _vfp. Activeform. Aaabbb (_fm) call the custom to aaabbb (_fm), have a mistake, can't find aaabbb (_fm), but can be realized in the form, build the form after error, why?

CodePudding user response:

Maybe your custom method, is in the form set level, therefore, may be this: _vfp. Activeform . The Parent . Aaabbb (_fm)

Form set is really a strange thing, I really can't figure out the necessity of its existence, maybe just for backward compatibility,
If the use of VFP in new project design, remember to forget about the following concepts:
1. General (General field)
2. The FormSet (form)
3. The PUBLIC (global variable)
