your query is not clear vava. Do you want to edit the xml file from your program or do you want to use it as a data file in which to save data. If you just want to load and use the xml file, you will have to create an xmldoc object. (there is some xml 3.0 library or something that you need to reference) But if you want to have editing facility in your program, it will need some heavy coding. Think you are upto it? Or search on the internet for some xml edit activex controls.
