MessageBoxOptions Enumeration

Specifies options on a MessageBox.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

[FlagsAttribute] 
public enum MessageBoxOptions
/** @attribute FlagsAttribute() */ 
public enum MessageBoxOptions
FlagsAttribute 
public enum MessageBoxOptions

 Member nameDescription
DefaultDesktopOnlyThe message box is displayed on the active desktop. 

This constant is the same as ServiceNotification except that the system displays the message box only on the default desktop of the interactive window station

DefaultDesktopOnly will cause the application that raised the MessageBox to lose focus. The MessageBox that is displayed will not use visual styles. For more information, see Rendering Controls with Visual Styles.

RightAlignThe message box text is right-aligned. 
RtlReadingSpecifies that the message box text is displayed with right to left reading order. 
ServiceNotificationThe message box is displayed on the active desktop. 

The caller is a service notifying the user of an event. The function displays a message box on the current active desktop, even if there is no user logged on to the computer.

This enumeration is used by the MessageBox class.

If you do not want to specify this parameter when calling methods on MessageBox, you can pass in 0 instead.


private void validateUserEntry2()
{

    // 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,
            MessageBoxIcon.Question, MessageBoxDefaultButton.Button1, 
            MessageBoxOptions.RightAlign);

        if(result == DialogResult.Yes)
        {

            // Closes the parent form.

            this.Close();

        }

    }

}


private void ValidateUserEntry2()
{
    // Checks the value of the text.
    if (serverName.get_Text().get_Length() == 0) {

        String message = "You did not enter a server name. "
            + "Cancel this operation?";
        String caption = "No Server Name Specified";
