Hello,
I have an MFC application and I have an issue where it does not disappear when minimized to the system tray.
It does correctly show an icon in the system tray when minimized, but it shows up just above the task bar on the left side of the screen. It does not display an icon in the taskbar, and I do not want an icon in the task bar.
How do I get the application to completely disappear from the screen?
I have included the relevant source code.
