You are displaying the message, "Connection Established" before you even try to open the connection. I suspect you haven't specified the server name correctly. On my machine (using MS SQL) it is "Server=.\SQLEXPRESS;". When I try with either "Server=localhost" or "Server=(localhost)" I don't get the connection. Try this (with a different value for servername)

Dim odcell = OutgoingdeliveriesDataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value.ToString()
Dim _conn As New MySqlConnection("Server=.\servername; Username= root; Password =; Database = forms")

With cmd

    _conn.Open()

    If _conn.State = ConnectionState.Open Then

        MsgBox("connection established")

        .Connection = _conn
        .Parameters.Clear()

        .CommandText = "SELECT FormName, Description FROM FormMaintenance WHERE FormCode = @Code"
        .Parameters.AddWithValue("@Code", odcell)

        Dim dr As MySqlDataReader = cmd.ExecuteReader()

        If dr.Read() Then

            Dim _comm As New MySqlCommand()
            With _comm
               .Connection = _conn
               .CommandText = "UPDATE outgoingdeliveries SET FormName = @iName, Description = @iDesc WHERE FormCode = @iCode"
               .CommandType = CommandType.Text
               .Parameters.AddWithValue("@iCode", odcell)
               .Parameters.AddWithValue("@iName", dr.Item(0).ToString())
               .Parameters.AddWithValue("@iDesc", dr.Item(1).ToString())
               dr.Close()
            End With

            Try
                _comm.ExecuteNonQuery()
            Catch ex As MySqlException
                MsgBox(ex.Message.ToString())
            End Try

       End If

   End If

End With
