Implementations
The message box contains three push buttons: Abort, Retry, and Ignore.
The message box contains three push buttons: Cancel, Try Again,
Continue. Use this message box type instead of
MB::ABORTRETRYIGNORE
.
Adds a Help button to the message box. When the user clicks the Help
button or presses F1, the system sends a
wm::Help
message to the owner.
The message box contains two push buttons: Retry and Cancel.
The message box contains three push buttons: Yes, No, and Cancel.
An exclamation-point icon appears in the message box.
An exclamation-point icon appears in the message box.
An icon consisting of a lowercase letter i in a circle appears in the message box.
An icon consisting of a lowercase letter i in a circle appears in the message box.
A question-mark icon appears in the message box. The question-mark message icon is no longer recommended because it does not clearly represent a specific type of message and because the phrasing of a message as a question could apply to any message type. In addition, users can confuse the message symbol question mark with Help information. Therefore, do not use this question mark message symbol in your message boxes. The system continues to support its inclusion only for backward compatibility.
The first button is the default button. MB::DEFBUTTON1
is the default
unless MB::DEFBUTTON2
,
MB::DEFBUTTON3
, or
MB::DEFBUTTON4
is specified.
The second button is the default button.
The third button is the default button.
The fourth button is the default button.
The user must respond to the message box before continuing work in the window identified by the hWnd parameter. However, the user can move to the windows of other threads and work in those windows.
Depending on the hierarchy of windows in the application, the user may be able to move to other windows within the thread. All child windows of the parent of the message box are automatically disabled, but pop-up windows are not.
MB::APPLMODAL
is the default if neither
MB::SYSTEMMODAL
nor
MB::TASKMODAL
is specified.
Same as MB::APPLMODAL
except that the
message box has the WS_EX::TOPMOST
style.
Use system-modal message boxes to notify the user of serious,
potentially damaging errors that require immediate attention (for
example, running out of memory). This flag has no effect on the user’s
ability to interact with windows other than those associated with hWnd.
Same as MB::APPLMODAL
except that all the
top-level windows belonging to the current thread are disabled if the
hWnd parameter is NULL. Use this flag when the calling application or
library does not have a window handle available but still needs to
prevent input to other windows in the calling thread without suspending
other threads.
Same as desktop of the interactive window station. For more information, see Window Stations.
If the current input desktop is not the default desktop,
HWND::MessageBox
does not return until the
user switches to the default desktop.
Displays message and caption text using right-to-left reading order on Hebrew and Arabic systems.
The message box becomes the foreground window. Internally, the system
calls the
HWND::SetForegroundWindow
function
for the message box.
The message box is created with the
WS_EX::TOPMOST
window style.
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.
Terminal Services: If the calling thread has an impersonation token, the function directs the message box to the session specified in the impersonation token.
If this flag is set, the hWnd
parameter must be NULL. This is so that
the message box can appear on a desktop other than the desktop
corresponding to the hWnd
.
For information on security considerations in regard to using this flag, see Interactive Services. In particular, be aware that this flag can produce interactive content on a locked desktop and should therefore be used for only a very limited set of scenarios, such as resource exhaustion.
