Manipulating Windows.

[Gintaras]

So am I to understand that this function will now put a button in the taskbar for a window that was not hidden by this function?
Anyway to get a window registered in the taskbar that was not there before?

Look here: Multi-monitor taskbar
It uses another method.

Function TaskbarButton also can be modified to add any window.

Add WS_EX_APPWINDOW extended style. Also it must be visible. Or use ITaskbarList interface, like in my multimonitor taskbar.

Also, is there anyway to change a windows style? Like adding a maximize, minimize, close button to

SetWinStyle

Perhaps could you open a window inside a QM dialog?

No.
