From its fluent ribbon, 'master_xl file.xlsm' opens and closes xl files: 'sub_xl1.xlsm' and 'sub_xl2.xlsm' .
When master_xl file.xlsm is open I wish its icon to appear in the within the stack of xl_icons (as default) in the Windows7 Taskbar tray
When sub_xl1.xlsm opens, its icon should also appear in the stack of xl_icons
However, sub_xl2.xlsm opens I dont want its icon visible in the Taskbar tray. When I want to bring the Window for sub_xl2.xlsm to the front (to read it), I will just activate it via the master fluent ribbon.
How can I use code to exclude the icon for sub_xl2.xlsm from the Taskbar?
