#91411 — Getting an image from a file on windows

Hello,

I have been working on a function that gets a bitmap of the thumbnail for a file. I have had problems getting a large image (256x256) and I was wondering if someone could help me on one object initialization that is driving me nuts.

I have code here: https://gist.github.com/IronManMark20/a83fe7ff7ea9b40c09af

I need to initialize a *void pointer for the third argument for SHGetImageList (ref https://msdn.microsoft.com/en-us/library/bb762185). 

What should the initialization look like (please give me example code, not just "Oh it should be a ctypes.c_void_p").

Thanks!!!

Have you tried byref(hico)?

Thanks so much! That seems to have done it. Now I get to figure out how to get the image.

Could you suggest how I could get an hIcon from the newly drawn image? I have been trying, but I haven't found anything.
