write metadata .net 1.1

[Trebor100]

Hi - I really hope someone can help me here as am well stuck. I'm forced to use .net 1.1 and need to be able to write the title and comment onto a .jpg via a web interface (prop id's 40091 and 40092 respectivly).

Can anyone out there help? from hours of googling (is that a word?) I havent been able to find a solution that works in the 1.1 framework

Cheers all,

Rob

I think you'll need to look into IPTC or EXIF. There are many libraries available on the web (some opensource) that you can use to accomplish your goal. I'm certainly not an expert in this area, but I have read a few articles and if I'm not mistaken IPTC is probably where you should start.

Hope this helps.

found a nice easy way to do this in the end - code extracts as follows:

Bitmap MyPhoto = new Bitmap(Server.MapPath(".") + "/tmp/" + fn);
PropertyItem[] props = MyPhoto.PropertyItems;

props[0].Id=40093;
props[0].Type=2;
props[0].Len=strAuthor.Length;
props[0].Value=bAuth;

MyPhoto.SetPropertyItem(props[0]);
MyPhoto.Save(Server.MapPath(".") + "\\tmp\\" + "MD_" + fn,System.Drawing.Imaging.ImageFormat.Jpeg);

MyPhoto.Dispose();
MyPhoto = null;
System.IO.File.Delete(fpn); //where fpn is the orig file.
