The Button.DialogResult property and the Form.ShowDialog method use this enumeration.

The following code example demonstrates how to display a MessageBox with the options supported by this overload of Show. After verifying that a string variable, ServerName, is empty, the example displays a MessageBox, offering the user the option to cancel the operation. If the Show method's return value evaluates to Yes, the form that displayed the MessageBox is closed.

	private void validateUserEntry5()

		// Checks the value of the text. 

		if(serverName.Text.Length == 0)

			// Initializes the variables to pass to the MessageBox.Show method.

			string message = "You did not enter a server name. Cancel this operation?";
			string caption = "No Server Name Specified";
			MessageBoxButtons buttons = MessageBoxButtons.YesNo;
			DialogResult result;

			// Displays the MessageBox.

			result = MessageBox.Show(this, message, caption, buttons);

			if(result == DialogResult.Yes)

				// Closes the parent form.
