Introduction

The MapPoint Find sample uses the Microsoft MapPoint ActiveX control to replicate the find address, find place and data, and find latitude and longitude functionality of the MapPoint CD-ROM product.

This download consists of Microsoft Visual Basic 6.0 project files. To run the sample, open the Project1.vbp file in Visual Basic 6.0 and run the project. When the sample application opens, click Find. Switch between the Address, Place/Data, and Lat/Long tabs to find different types of locations on the map.
