Negri,

We are probably all blind.

The creation of a connection will normally never thrown an error how many
Try blocks you set around it. It only places that string in the property
oledb.connectionstring.

The connection is actually executed in the open.

What I would do in your place is checking again your connection string.

I hope this helps,

Cor.

Hi Cor, i have tried to change connection string, but i don't get anything.
I'm going to open a new post, with the error, to try luck.
Thanks for everything.
