Rick,

This is a copy of a response I sent to another member on 13/09/1998.


You may have made the same mistake I did.

I selected the view code button in the class browser; made a change to the displayed code and saved it.

The next time I tried to get into the class browser I got the invalid buffdirty call and VFP 6 shut down.

I looked in the VFP 6 root directory and saw a viewcode.prg and a viewcode.bak. What I had done was modify the viewcode.prg, not the class.

I deleted both files then went back to the class browser and it worked okay. VFP even put a "good" viewcode.prg back into the root directory so the view code button worked, also.

Hope this helps!

Dale
