The Error Message:

Exception Details: System.MissingMemberException: Public member 'EOF' on type 'String' not found. On Line 20.

Source Error:

Line 21: NoUser.visible = True
Line 22: Else

It's been a long while since I've did asp.net, and I cannot remember this error. Thx in Advance.MySQL is your SQL string and it doesn't have an EOF method or property.EOF is a property of the recordset, not a string holding a SQL statement.
