Creates, displays, and operates a message box. The message box contains application-defined message text and title, any icon, and any combination of predefined push buttons.
int MessageBoxIndirectA( const MSGBOXPARAMSA *lpmbp );
Type: const LPMSGBOXPARAMS
A pointer to a MSGBOXPARAMS structure that contains information used to display the message box.
If the function succeeds, the return value is one of the following menu-item values.
If a message box has a Cancel button, the function returns the IDCANCEL value if either the ESC key is pressed or the Cancel button is selected. If the message box has no Cancel button, pressing ESC has no effect.
If there is not enough memory to create the message box, the return value is zero.
||The Abort button was selected.|
||The Cancel button was selected.|
||The Continue button was selected.|
||The Ignore button was selected.|
||The No button was selected.|
||The OK button was selected.|
||The Retry button was selected.|
||The Try Again button was selected.|
||The Yes button was selected.|
When you use a system-modal message box to indicate that the system is low on memory, the strings pointed to by the lpszText and lpszCaption members of the MSGBOXPARAMS structure should not be taken from a resource file, because an attempt to load the resource may fail.
If you create a message box while a dialog box is present, use a handle to the dialog box as the hWnd parameter. The hWnd parameter should not identify a child window, such as a control in a dialog box.
