1.How to create a sample application?
- please read this article and create a sample application like this：
Visual Studio 2019 创建MFC项目并运行_vs2019创建mfc项目-CSDN博客
（1）first, we need a framework.h to include the necessary file from MFC library
（2）pch.h and pch.cpp : just to include some file and complie more efficiently
（3）targetver.h : to include necessary file for different version
（4）resource.h define some macro for the MFCApplication1.cpp to use
and the following two file are the main files actually:
--MFCApplication1Dlg.cpp:
This file primarily implements the functionality for the main dialog of the MFC application, including initialization, message handling, and painting.
It helps draw the main GUI and menu of this application
--MFCApplication1.cpp:
Overall, this file sets up the application class, initializes the application, creates the main dialog, and handles the dialog's response. It contains essential initialization and cleanup code for the MFC application.
It defines the operations of this class and it's the main file of this application
and the sample show as below

3.if you want to learn from the video:
(1)this can make you a quick start , and remember code by yourself to improve
(2)Hopefully, I will go through the whole videos above and create my own MFC application by coding myself. Then I will write some articles to share with you as soon as possible.
