The SCT file that stores all the memo field data [including your methods and properties] is probably corrupted.

First, make a COPY of both the SCX and SCT files of your formset. Next issue the command:

COMPILE FORM FORMSETNAME [or COMPILE CLASS FORMSETNAME.SCX]

Modify your formset to see if your code is back in place. If that does not work, restore those 2 files from the copy you just made. Then try the following:

use myformset.scx
set alternate to scxcode.prg
set alternate on
list off methods, objname for not empty(methods)
set alternate off
set alternate to
use
modi comm scxcode

This will at least provide you with the method code that is recoverable so you can start piecing it all back together. This will not be an easy or quick process, but it can save some of the code.

Next, I [as well as many others] do not use formsets. We only use forms. The immediate benefit I see to this in your case is that you would have only lost the work of 1 form instead of 3. The second advantage is performance. You only run the form you need when you need it.

>Today, I find a strange problem/bug in my vfp formset.
>My FormSet got 3 little forms,One main forms.
>In the Main Forms, It got many method.
>e.g FieldValidation(), Print(), DeleteValidation()..etc.
>
>The Strange problem is:-
>The content (the coding) in the method of "Print()" is exchanged with
>The content (the coding) of the method DeleteValidation().
>
>More, content of A() exchange with the content of C()...
>the content of D() exchange with the content of W()....etc.
