objCmd.Parameters.Add(New SqlParameter("@IssueName", _

SqlDbType.VarChar, 40))

objCmd.Parameters("@IssueName").Value = IssueName.Text

objCmd.Connection.Open()

' Test whether the new row can be added and display the

' appropriate message box to the user.

Try

objCmd.ExecuteNonQuery()

Message.InnerHtml = "<b>Record Added</b><br>" & strSQL1

Catch ex As SqlException

If ex.Number = 2627 Then

Message.InnerHtml = "ERROR: A record already exists with " _

& "the same primary key"

Else

Message.InnerHtml = "ERROR: Could not add record, please " _

& "ensure the fields are correctly filled out"

Message.Style("color") = "red"

End If

End Try

objCmd.Connection.Close()

End Sub

</script>

database looks like this

IssueID      UniqueIdentifer

IssueName   varchar(50)

 

Any idea on why I cannot get my connection string to work have I missed something or trying to connect to it wrongly?
