private void ToolStripItem1_Paint(Object sender, PaintEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();

messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Paint Event" );

Private Sub ToolStripItem1_Paint(sender as Object, e as PaintEventArgs) _ 
     Handles ToolStripItem1.Paint

    Dim messageBoxVB as New System.Text.StringBuilder()
