[python-win32] Files in clipboard with DropEffect?

[Stuart Axon]

Cheers, that works great :)

CF_PREFERREDDROPEFFECT = win32clipboard.RegisterClipboardFormat(
        shellcon.CFSTR_PREFERREDDROPEFFECT)
    effect_str = win32clipboard.GetClipboardData(CF_PREFERREDDROPEFFECT)
    de = struct.unpack("i", effect_str[:4])[0]

Yeah - something like:

CF_PREFERREDDROPEFFECT = win32clipboard.RegisterClipboardFormat( 
shellcon.CFSTR_PREFERREDDROPEFFECT)
effect_str = GetClipboardData(CFSTR_PREFERREDDROPEFFECT)
de = struct.unpack("i", effect_str[:4])[0]

Cheers,

Mark
