EXAMPLES

1. Graphics – Scrolling List

The Scrolling List example shows how to draw formatted text to a bitmap and then scroll that bitmap vertically in a panel, a pixel at a time.

2. Graphics – Screen Updating

5. Data Entry, Lists, Save and Restore

6. Simple Text Printing

An example that shows how to create a component to simplify the printing process for any application that needs to print plain text.

7. Recursive Folder Search

Recursion is a simple and effective technique for searching in a heirarchy.  This example shows how to access the folder heirarchy to list all files and folders.  It can be used as a pattern for any similar recursive procedure.

8. Command-line Arguments

VB .Net provides easy access to the command that was used to start an application.
