I'm looking for a way how i can create thumbnails for nearly any format
windows supports, the same way the windows shell (windows explorer) does.
I've read something about using active document, but I dont have a clue
where to begin. I'm familiar with C++ and COM, so I only need the name of
some classes or interfaces. I want to create those thumbnails in arbitrary
sizes, so it does not make sense to read out existing "thumbdb"-files. I
also dont want to use an imaging class, for that i want to create the
thumbnails for arbitrary formats (e.g. videos, images, htmls ...). I only
want to use the functions the windows shell api provides and supports. any
help would be appreciated. thank you in advance.
