Explorer thumbnails (winXP)

Question

I have a file format I need to be able to show in explorer thumbnails. Since the target system is windows XP, the Vista PreviewHandler API will not be suitable. Ill be using c++.

How would I do it?

Answer 1

You'll need to register a shell extension for your file type. The extension contains code that extracts/generates the thumbnail by implementing the IExtractImage interface.

See: IExtractImage Interface on MSDN
