This enumeration is used by the MessageBox class.

The following code example shows how to use a MessageBox to inform the user of a missing entry in a TextBox. This example requires that the method is called from an existing form with a Button and a TextBox on it.

Visual Basic
Private Sub button1_Click(sender As Object, e As System.EventArgs)
    If textBox1.Text = "" Then
        MessageBox.Show("You must enter a name.", "Name Entry Error", _
           MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
    Else
        ' Code to act on the data entered would go here.
    End If
End Sub
C#
private void button1_Click(object sender, System.EventArgs e) {
   if(textBox1.Text == "") {
      MessageBox.Show("You must enter a name.", "Name Entry Error",
         MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
   }
   else {
      // Code to act on the data entered would go here.
   }
}
Visual C++
private:
   void button1_Click( Object^ sender, System::EventArgs^ e )
   {
      if ( textBox1->Text->Equals( "" ) )
      {

            MessageBoxButtons::OK, MessageBoxIcon::Exclamation );
      }
