Hi Nancy ,
The problem isn't solved.
Well ,when I check the memo field in VFP ,it is a blank memo ,but when I open the memo.fpt with notepad,it contain the context that store in memo b4.
As time when by ,the FPT file become hung .

Is there any method to add field to table and delete field in table during runtime ?

Thanx for help
