Hello!
I need to modify the metadata of a jpeg file, i managed to modify metadata that photoshop displays (XMP) but not the metadata that windows displays when you right-click on jpeg file and choose Properites >> Summary. Does anyone know how to modify that metadata also?
P.S.
To modify XMP metadata the one that Photoshop displays in file info i used a library provided at:

I have tryed it, of course and it's good for extracting Metadata as a raw byte[] which can than be converted to string and modifyed, but if XMP data is stored pretty much like XML data there and can be easly parsed, than the data that Windows encrypts in image Metadata looks like this:
__
>?HHAdobe Photoshop CS WindowsH2004:09:24 10:41:45CopleftTitle WinCOMM winAuthor WINKEY WINSubject Win??Vf??
__
while in XP in image Properties >> Summary i entered following values:
Title Win
COMM win
Author WIN
KEY WIN
Subject Win
so in the output string i see only values without the keys, and i don't know how to parse that.
Any suggestions?
