Update Lists in SharePoint using web services

Hi,

I got the following email from a developer,it says as follows:
"
Hello Moustafa. I don't want to bother you, but I've been searching for examples of MOSS 2007 Web Services development, and I have not found anything. I have this situation. There is a document library with some items on it. I need to edit some properties of a document (on that doc libr) from an Office application, using the MOSS web services. I need to change the Title and the Category of that document, but I don't know how to do that. Could you help me please, with an example that could guide to me how to do that? ( If you have some interesting links or something about MOSS 2007 development (using web services or api) I'm going to thank you so much ). Regards ...
