You notice how .doc files (word documents), have extra tabs when you select properties from windows explorer. How does this work. I looked in the registry and found some encrypted info under a ShellEx key for the Doc file type (HKEY_CLASSES_ROOT\.doc\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1} with a value of {9DBD2C50-62AD-11d0-B806-00C04FD706EC}). I copied that stuff over to the key for TXT files and got the extended tabs for TXT file properties. apparently the {9DBD2C50-62AD-11d0-B806-00C04FD706EC} value maps to a DLL (shdocvw.dll) in the HKEY_CLASSES_ROOT\CLSID\ section of the registry. unfortunately I can't get this to work for other file types, I must be missing something. what I want to do is make my own DLL to get extended info from mp3's (like winamp does), but be able to view it from the file properties in explorer.
Well - I think I figured out something - Actually I think it's exactly what you want, it's just I have no clue how to do it (nor have I tried, not yet at least). I think that would be an interesting project though, so I may have a crack at it. Anyways - Check out IShellView in the MSDN Library. It's a Shell Interface (and I have absolutely no clue how to use it). It has a method, AddPropertySheetPages, and I believe that is what you're looking for. Check it out - if it's what you're looking for, Great! If not, well, then - I tried. One of these days, if I have some extra free time, I'll check it out and let you know if I come up with anything.

Update - I was totally wrong - lol --- I misread something... Anyways - instead of IShellView - check out IShellPropSheetExt - that's what you want - I know for sure now (I think). That is also a Shell Interface that I have no clue what to do with. Check out this in MSDN: http://msdn.microsoft.com/library/de...etHandlers.htm It seems rather in depth, but it would be interesting, nevertheless - but anyways...
I am also very interested in how you can reference the information found on the Summary tab of the properties of the file. Reading the information on the website supplied I can get a handle on how to create my own shell extenstion information, but why beat a dead horse when it has already been done.
I want to be able to parse through several Hundred Documents and database all the information on that summary tab page to make it searchable through a front end for our company software.
A program that can do this for all files that MS has a summary page for would be very benefitial. Any help you can lend will be greatly appreciated.
