IThumbnailProvider RRS feed

  • Frage

  • Hi,

    I would like to create thumbnail previewer for all possible file types. As far as I understood, an application can implement IThumbnailProvider and IThumbnailHandler in order to provide a thumbnail for a file. Now, I found many tutorials describing how to implement a  thumbnail provider. But I didn't find any "how to USE a thumbnail Provider". How do I get the instance? The info must be stored somewhere in the registry under the file type (I would expect), but where?

    Does anybody have experience with that or an example?

    Thanks and regards,

    1. Create a IThumbnailCache, CLSID_LocalThumbnailCache

    2. Access the cache with GetThumbnail.
