GUID help...

all,

how would i figure out what the GUID for .pdf Titles would be?
right now I'm using an asp script to return file information. I can get the file title if the file is a .doc type....but not if it's a .pdf type, even though a title is present in the properties. I can however get the .pdf file name as it's stored in the directory...just not the Title.

any ideas on how to get that .pdf Title?

thanks!
