I want to make a mfc window program, and then after the window is minimized, move the mouse to the program icon on the taskbar, the program thumbnail will be displayed, and at the top of the thumbnail, the font information will be displayed. Now I don’t know which mfc class to use

What I have tried:

The program is not activated, move the mouse to the program icon in the taskbar, which class of MFC to use, and display text information at the top of the thumbnail

You can use the IsIconic function (winuser.h) - Win32 apps | Microsoft Docs[^] to test if the Window is minimized. You should then be able to get information that will help you create a second thumbnail window to display your extra information.

Well that is a different question. I guess you have to use something like EnumWindows function (winuser.h) - Win32 apps | Microsoft Docs[^]. See how to get the handle of all activated window in taskbar?[^].
