Using Google Geocoding and VDF to Create Google Client Maps
We recently had a requirement to create maps that displayed customer locations and key details, such as names and addresses. In addition, we wanted the ability to filter the map results to show only certain categories of customers.
The Google Maps Solution
Following some initial research, Mike created a Google GeoCoding client in Visual DataFlex and used that in a program to run through our customer table, storing the returned latitude and longitude results for each row, and pausing for a second every ten requests. It took a little while to process all of our data, but not too long.
With that information stored in the database, the other steps were relatively simple:
- Build a web service that provided customer information, filtered by the requested criteria, including the stored location data (latitude and longitude)
- Create a little Unicorn InterGlobal .PNG marker to use on the map
- Create an HTML web page with the required selection controls on it
Try out the results for yourself with Mike’s Google Maps Customer Location Map Generator.
To find out more about what Mike did, and to try the Microsoft Bing solution, read Creating a Customer Location Map on our website.

Pervasive PSQL v11 SP1 Trial Beta Version Available

Mertech Flex2SQL v11 Driver Released
Mertech have announced the release of their Flex2SQL v11 driver this month.
The main goal of the v11 release is to ensure coexistence with changes to the database structure outside of the DataFlex tools. The new relationship synchronizer exports DataFlex relationships to SQL backends and also allows relationships created directly on the backend to be imported into the DataFlex environment by updating the .INT file.
Read the complete list of new features and enhancements in the Flex2SQL v11 driver release.
