    import win32con

    listHicon = ExtractIconEx("c:\OpenOffice.exe",0)

    test = 
LoadImage(listHicon[0],"c:\OpenOffice.exe",0,0,0,win32con.LR_DEFAULTSIZE)   
  
   
    tupleIcon = GetIconInfo(test)/

To use GetIconInfo argument should be pyHandle. listHicon is array of 
Hicon. LoadImage return Handle, but the last argument must be an pyHandle
(by the interpretor error)

But normally is good by this API : 
http://docs.activestate.com/activepython/2.4/pywin32/win32gui.html

I use LoadImage because LoadIcon is depreacted and it return an hicon.


I doesn't have more idea ...

Thanks.


PS : the demo menu and taskbar use icon only to display it in another 
module, but i want get bitmapBit of icon to send it to an inventory server.
