Thank Fabio, I've been away and I red your reply just now.
I'll test your procedure but it sounds like it was a solution to my problem.
:-)
Anyway I think that the class which gave the problem was one containing a MSCAL ole Object . Why I got this error ?
I can open without problem the VCX class till the VFP8 version.
I made the class with VFP6.


Grazie Fabio, sono stato altrove e ho letto solo ora la tua risposta.
Penso che sia la soluzione a questo problema. La aproverò in giornata.
Comunque ho individuato il record birichino. é quello correlato ad una Classe container contenente un oggetto OLE MSCal.
Sai darmi una spiegazione logica a questi errori ?
Ciao e grazie ancora

>>The error is mentioned even in the VFP help but I haven't undersatood very well what to do. Anyway this morning I realized that it was just a record in the vcx table that had the error, so I manually deleted it and succed in opening the vcx file with VFP 9.
