Abstract
The message system of Windows controls the operation of applications VB programs,and message processing is key mechanism to Windows.If we know the mechanism of message processing and master the technology of sub-class,we can enhance the functions of windows by self-defined windows.This paper introduces the mechanism of VB message processing,then presents the sub-class of Windows OS and its principle.At last,this paper shows the procedure of creating self-defined windows by sub-class,and an implementation of the self-defined windows.
