[RESOLVED] [2005] Save to DB failure

datasetUserinfo is filled with values from my DB (using sqlclient)
datagridviewUserinfo is bound to my dataset

I am uploading data ( a CSV file ) into my dataset (using ODBC)
the dataset reflects the row additions (datasetUserinfo.Tables("userinfo").Rows.Count) as does datagridviewUserinfo

I am attempting to save to my database using the following code:

VB Code:

Dim CmdBuilderUserInfoAs New SqlClient.SqlCommandBuilder(UserInfoDataAdapter)
            UserinfoDataAdapter.UpdateCommand = CmdBuilderUserinfo.GetUpdateCommand
            UserinfoDataAdapter.Update(datasetUserinfo, "userinfo")

no dice. Nothing is updated. I don't even get an error message.
Could the glitch come with using more than one connection type on the same form? Sql and ODBC
