Florida (from DCW data); Locate a City

Simple Samples

Choose City

This sample shows how to build project files to present selected data with a dependence on scale. Zoom in a little and select any city from the "Choose City" drop down list. The map view will move to highlight the area centered on that city, with no change in the map scale.

This sample is created using a TIFF format raster image and a vector map layer held in a SQL database. The SQLLayers function provides for the storage of all the vector geometry in a single SQL database file.

The list of cities presented in the sample is built from the table "dcw1pppoint_FEA" from the SQLLayer stored in dcw_data.mdb. The list is dynamically connected to the vector data. Any changes made to the vector data are reflected to the list of cities.
