2.3.6 Message Box Options............................................................................

The uType argument is used to provide some additional options to the message box. First,

it is used to display one or a few buttons. The buttons depend on the value specified for

the argument. If this argument is not specified, the message box displays (only) OK.

Otherwise, you can display a message box with a combination of selected buttons.

To display one or more buttons, the uType argument uses a constant value that controls

what button(s) to display. The values and their buttons can be specified as follows:

Constant Buttons

MB_OK (^)
MB_OKCANCEL (^)
MB_ABORTRETRYIGNORE (^)
MB_YESNOCANCEL (^)
MB_YESNO
MB_RETRYCANCEL
MB_HELP
Here is an example:
BOOL Whatever()
{
MessageBox("Due to an unknown internal error, this application will now close.\n"
"Do you want to save the file before closing?",
"Application Warning",
MB_YESNO);
}

buttons are as follows:
