Dim sqlTable As New DataTable

sqlTable = DBTools.MySql_FetchDataTable(sqlQuery, myDatabase)

Compute_VIN.form_no = DataGridView1.SelectedRows(0).ToString
Compute_VIN.lname = sqlTable.Rows(0)("lastname")
Compute_VIN.fname = sqlTable.Rows(0)("doctable.firstname")
Compute_VIN.mname = sqlTable.Rows(0)("doctable.maternalname")
Compute_VIN.ShowDialog()

please .. thank you

Firstly, google 'using table aliases in mysql' and clean that query up - that is just plain nasty.

Secondly, pop a break in your code after that (nasty) query, copy what the value of the query string and drop it into a query window on whatever you're using to manage mySQL -there'll be an error in there somewhere.
