>>>I'm writing a business object in .Net that is using a VFP database container with autoincrement primary keys. I want to send an INSERT statement using an OLEDB command and get back the value that was assigned to the auto increment field. I know about the GETAUTOINCVALUE() function that returns this value. The problem is getting the value back to my .Net class. I looked in the help file and this function is not listed in the "Supported VFP Commands" or the "Unsupported VFP Commands".
