open file dialog

A Dialog window is an independent sub-window meant to open temporary form apart from the main Swing Application Window. Most Dialog present an error message or warning to a user, but Dialog box can present images, directory trees, or just about anything compatible with the main Swing Application that manages them.

   In this tutorial we will make a simple program called “Picture viewer”. This program will open a selected picture or image and it will be shown on the main form of the program. In the process of coding of this program we will use Open File Dialog component and Picture box component. Preparation    First of all you need to create a new “Windows Forms Application” project. Then you need to put a Picture box component and Button component on the form. After that you also need to add Open File Dialog to the project.
