Save and Read Combo Box Items from an XML File
Introduction When discussing file processing, we mentioned that it is sometimes necessary to automatically save a file when an application exits, without any intervention from the user. You can also solve this exact problem using XML. The ever growing strength of XML is in its ability to let modify a file however but still make that file usable by any environment that needs its content. We are going to create an XML file that holds a list of items for a combo box. Once the file exists, it can be processed or modified by any application that can read XML. We will load the file automatically when the application opens and retrieve the values of the elements to complete a combo box . While using the application, we will allow the user to change the list. When the application closes, we will retrieve the list of items from the combo box and update (in reality) recreate the list that includes the new items. Practical Learning: Using XML Values 1.
