PDFViewSimpleTest - VB

This sample shows how to use PDF viewer control in a basic project. The sample uses a number of built-in features from PDFViewCtrl to implement document navigation, text highlighting, markup, and editing. If you are looking for a sample showing how to further customize the viewer (e.g. by implementing custom tools or custom GUI elements), please take a look at PDFView sample project.
