Saving and Loading

This is a case where the topic is too large to handle in a single post. Whole chapters of books are devoted to data, datasets and read/write. In a nutshell Dim ds as DataSet . . . (add your data to the dataset) . . . ds.WriteXML("MyData") To read XML data back use: ds.ReadXML("MyData")

How can I do that? How can I save just the data the user has entered?

You don't actually want to save the form, you just want to save the data. There are many ways to read and write data. Probably the easiest is to create a dataset to store your information and then use the dataset ReadXML and WriteXML functions.
