This document provides guidance on planning an object-oriented application in Visual Basic 2010. It discusses developing the application like building a home, with the programmer as the builder. It emphasizes involving users in planning to match their needs. A TOE (Task, Object, Event) chart should be used to plan the required tasks, objects, and events. Key aspects to plan include what information needs to be displayed, entered, and calculated. Objects like labels, buttons, and text boxes should be identified and assigned tasks. Events that trigger tasks should also be identified. The document provides guidelines for sketching the user interface, such as using white space to group controls and following window standards for layout and labeling.
