I'm afraid that IExtractImage is not yet exposed by pywin32 - it would not be too hard if you are interested in testing a new implementation. Note that IExtractIcon is exposed - that may nor may-not work for you though.

IExtractImage seems to be the way to access the thumbnails that Windows Explorer uses. (I can't use PIL or similar because I'm previewing AutoCAD .dwg files). I am adapting some Delphi COM code (from here) as follows--i've removed the Malloc and other unnecessary statements: --begin delphi code-- if NOERROR = SHGetDesktopFolder(DesktopFolder) then DesktopFolder.ParseDisplayName(0, nil, 'C:\WINNT', Eaten, ItemIDList, Attributes); DesktopFolder.BindToObject(ItemIDList, nil, IShellFolder, TargetFolder); TargetFolder.ParseDisplayName(0, nil, 'delphi_wallpaper1024.bmp', Eaten, ItemIDList, Attributes); TargetFolder.GetUIObjectOf(0, 1, ItemIDList, IExtractImage, nil, XtractImg); Malloc.Free(ItemIDList); --end delphi code-- --begin python adaption-- testPath = "C:\\" testFileName = "test.dwg" #also have tried test.bmp, test.png iSHFolder = shell.SHGetDesktopFolder() eaten, idList, attr = iSHFolder.ParseDisplayName(0, None, testPath) targetFolder = iSHFolder.BindToObject (idList, None, shell.IID_IShellFolder) eaten, targetIdList, attr = targetFolder.ParseDisplayName(0, None, testFileName) pprint ([eaten, targetIdList, attr]) extractImage = targetFolder.GetUIObjectOf(0, [targetIdList], pythoncom.MakeIID('{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}' ),0) --end python adaptation-- The python code fails on the last statement, throwing the following exception: TypeError: There is no interface object registered that supports this IID Any ideas on how to use this interface in python? I have googled for hours. Thanks, Steven James
