Could you see any similarities in the problem, described in Forum: Visual FoxPro Category: Troubleshooting Title: Fatal Error C0000005 and Edit boxes Thread #377352 Message #377352 and yours?

BTW, are you from China or USA and what's your name?

>I'm getting this fatal error C00000005 (FE C5) at random but repeatedly.The dbf file opened is the same one, with 4 memo fields and 1 gen field and several other char fields, with 30 records.The dbf file has no index file; only several records of the Gen field have data; others, memos included, are all empty.

>When I opens the dbf file and when there comes the FE C5, it is always the line, "thisform.refresh" that is causing trouble: it is the last code line (line
>53) in Mytxtbtns1.NavRefresh() of MyVcx.vcx. Mytxtbtns is modelled on the txtbtns in VFP7's Wizbtns. I didn't change much code of it. What follows is from VFP7ERR.Log: Line 53 is the trouble line. All other code line numbers are lines that somehow call NavRefresh().
