VSViewPort Control

The VSViewPort is a scrollable container control. With VSViewPort, you no longer have to write tedious code to synchronize scroll bars and picture boxes. You decide how big your window should be, then let the VSViewPort scroll your controls for you. You can use the VSViewPort to implement fill-out forms that are larger than the visible window, and print them later using the VSPrinter control.

The new VSViewPort control has a FocusTrack property that automatically scrolls the viewport so that the control with the input focus is visible to the user.

Note: Before you can use a VSViewPort control in your application, you must add the VSVPort8.ocx file to your project. Please refer to the VB documentation for details on adding controls to your projects.

To distribute applications you create with the VSViewPort control, you must install and register it on the user's computer. The Setup Wizard provided with Visual Basic provides tools to help you do that. Please refer to the Visual Basic manual for details.
