File MetaData (Summary)

[Guest]

G'Day

I'm trying to develop an application to manage my .pdf and .chm files. To do
so, I want to access (read/write) the Metadata of the files, like
File->Properties->Summary in the Windows explorer.

I already searched for solutions, but honestly I'm a bit lost... does
somebody knows an 'idiots guide' for that problem or perhaps some C# lines of
demo code?!

Cheers

I'm also looking for this information. If you happen to figure this
out, post it here for the rest of us, please.

I'm not sure about how this information is stored in other file types,
but this thread details how to do so with JPEGs.

Hope this helps!

Alright, after several days of tireless translation, I've figured out
how this stuff works.

The basic rundown is as follows:

The metadata you're looking for is actually made possible by the NTFS
filesystem. That is, if you try to find these properties on a
FAT32-formatted drive, you come up empty-handed.

There isn't an assembly in the .NET canon directly responsible for
accessing those properties, but it is possible to get at them via a
couple of COM interfaces, namely IPropertyStorage and
IPropertySetStorage. After some searching through the back alleys of
the 'net, I found some VB .NET code that had been written to do exactly
what I was searching for. I have since found a multitude of new reasons
to hate Visual Basic, and despise the coding practices that seem to
cling to it like a diseased remora.

Ahem.

I don't have a place to upload the code here, but if you'd like to email
me at lcrabtree AT goisi DOT com, I'd be happy to provide what I've got.
