Stephane-

>Anybody could tell me what i am doing wrong, my statement contains a "?" and VFP would normally ask the user for a parameter but since we are in a DLL and no interface is allowed, i trap the error with a IF Used("TableName") and then disconnect. Maybe VFP is confused by the ? inside a dll !!

This is a WAG, but it could be that the UI is getting thrown up before your error code can trap it...I guess I'd be really cautious to not use _anything_ that might put up a UI. Just a thought.
