.NET Framework Class Library

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)

Syntax

Visual Basic (Declaration)

<FlagsAttribute> _
Public Enumeration MessageBoxOptions

Visual Basic (Usage)

Dim instance As MessageBoxOptions

[FlagsAttribute] 
public enum MessageBoxOptions

C++

[FlagsAttribute] 
public enum class MessageBoxOptions

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

JScript

FlagsAttribute 
public enum MessageBoxOptions

Members

	Member name	Description
	DefaultDesktopOnly	The 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.
	RightAlign	The message box text is right-aligned.
	RtlReading	Specifies that the message box text is displayed with right to left reading order.
	ServiceNotification	The 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.

Remarks

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.

Example

Visual Basic

Private Sub ValidateUserEntry2()


    ' Checks the value of the text.

    If ServerName.Text.Length = 0 Then

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

        Dim Message As String = "You did not enter a server name. Cancel this operation?"
        Dim Caption As String = "No Server Name Specified"
        Dim Buttons As Integer = MessageBoxButtons.YesNo

        Dim Result As DialogResult

        'Displays a MessageBox using the Question icon and specifying the No button as the default.

        Result = MessageBox.Show(Me, Message, Caption, MessageBoxButtons.YesNo, _
            MessageBoxIcon.Question, MessageBoxDefaultButton.Button1, MessageBoxOptions.RightAlign)


        ' Gets the result of the MessageBox display.
