Function Reference

_WinAPI_MessageBoxIndirect

Creates, displays, and operates a message box

#include <WinAPIDlg.au3>
_WinAPI_MessageBoxIndirect ( $tMSGBOXPARAMS )

Parameters

Return Value

Remarks

When you use a system-modal message box to indicate that the system is low on memory, the strings pointed to by the
"Text" and "Caption" members of the $tagMSGBOXPARAMS 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.
