I'm creating a folder monitor that scans a folder for incomming xml files. When a xml file has been created in the folder, the file will be parsed, and after parsing it'll be moved to a "processed" folder. Now there are a lot of things that can go wrong obviously, and I'd like to be able to display a list of errors in this fasion:

Filename 1 >> error

Filename 2 >> error

But I realy dont know where to start. should I make a dictionary with string/string pair and display it in a tabel? Or what is the best option here. I tried googling, but it's hard to find examples of this.

thanks in advance.
