Try this
1. In the tree view of your application resources in the workspace pane, expand the icon branch and select the IDR_MAINFRAME icon. This brings the application icon into the editor area of the Developer Studio.
2. Using the painting tools provided, repaint the icon to display an image that you want to use to represent your application.
3. When you compile and run your application, you will notice your custom icon in the top-left corner of your application window.
I hop this is what you were asking for and that it helps you.
