I show the video in the MFC dialog box, and then draw a rectangle in onpaint. Then I drag the dialog box to find that the rectangle is still fixed at the position on the screen and cannot be dragged along with the dialog box, in addition, when another page overwrites the dialog box, the rectangle is drawn to another page, and the dialog box is minimized. The
