Read Metada information

mcimaging

Hi Everybody

In the Micorosoft windows Envirnment any operating systems you can
right-click on a specific file and go to properties
and you can view the various information (meta data) like Title, Subject,
Author, Comments etc,

now my problem is i need to get those meta data information using vb.net ?


File can be any type which windows operating system can open.
Example file extention can can be : .pdf,
..zip,
..dxf,
..shw,
..qpw,
..wpd,
..htm,
..xls,
..doc,
..mp3


Actually using "dsofile.dll" we can get some information only for Micorsoft
office file metat data ... but the problem is i have got lots of file type
which i need to get meta data information as i mentioend above...


any idea about this topic

regards

I'm not sure as I haven't used it in a while, but I thought the
FileInfo object could be used to retrieve this type of information. I
could be wrong though.

Hi Seth,

thanks very much for u r try, but unfortunetly we cant get more information
using
IO.FileInfo class.. it just basic information ....its not enough to continue
my project.
like i need the meta data information like Title, Subject,Author, Comments .
but if i use IO.FileInfo class its not showing us more information ......
so we need to find out any other way of doing this....

any comments ?

There are DLL's which implement certain interfaces and are registered with
the OS to provide the property values for different types of files. There
are property handlers and propertysheet handlers.

I had a book on shell programming but cannot find it now. Getting this info
is a large subject and the general method would be to emulate the OS and use
the interfaces built into these DLLs. All I can say is good luck.

Google for
ntfs file metadata

E.g. http://www.thinkdigit.com/forum/showthread.php?t=30292 (C#, but I think
it has all the info you need)
