I got the idl that I could convert to a typelib and then use
cc.GetModule("taskbar.tlb");
The only trouble is you have to specify the
import comtypes.gen.TaskbarLib as tbl
taskbar
=cc.CreateObject("{56FDF344-FD6D-11d0-958A-006097C9A090}",interface=tbl.ITaskbarList3)
instead of just:
taskbar = tbl.TaskbarList()
because the typelib from the IDL is missing, I am assuming it comes
with the Win7 SDK. This is a problem since I would have to ship the
generated interface if I decide to use this code.
Anyway usage is then straightforward:
taskbar.HrInit()
taskbar.SetProgressValue(hWnd,25,100)
Anyway I'm guessing/hoping there will be Windows 7 support in a future
version of win32com :-)
