I am experienceless on Windows Desktop programming. I would like to draw the frame window by myself. I searched on the internet and found the Bee Lee's article.
I used the method that descripted in this article , But I encounter a issue about the client area. When I resize the frame window ,the client area size doesn't be changed.
Below is the screenshot of a demo, I just added a status bar in the demo app. The size of status bar will not be changed when window size changed.
Any help would be greatly appreciated!
