How to place a TComboBox on the Windows Taskbar

Answer:

FindWindow('Shell_TrayWnd', nil) will get you the handle of the taskbar, you can 
then use this handle to manipulate the taskbar. For example, to move a combobox1 to 
the taskbar do:

1   { ... }
2   Combobox1.Left := 0;
3   Windows.SetParent(Combobox1.Handle, FindWindow('Shell_TrayWnd', nil));
4   { ... }
