VC + + in the use of Htcontrol Control class Chtdlgbase dialog box base class instance _c language

This article describes the VC + + interface Programming An MFC example, based on the Htcontrol Control class Chtdlgbase dialog box base class main file code. This program can complete the dynamic creation of the frame form, form appearance (customer area and non-customer area), adjust the size of the form, Invalid child window control, and other functions.

The specific implementation code is as follows:
