Greetings All,

I am interested being able to use PowerBuilder to iterate through rows in a datawindow and make calls to Google Maps Routing Service to get drivetime and distance (numerical values (e.g. 176, not '2 hours 56 mins')) and store those values in a table.

I think Inet used to be the way to go here, but I understand that HTTPClient introduced recently might be easier to use.

I am hoping for some guidance on what things in what order I would need to do in order to accomplish this.

The resulting code will be published on CodeXchange with attribution.

Essentially, I need to iterate through 8,400 rows of data and get the drivetime (in minutes) and distance (as numerical value) and the same table where the data lives.

I am willing to put some effort into this if someone can kindly provide some guidance.

I think it goes as follows:

  1. Call Google Maps Routing function using Origin and Destination Lat/Longs to get DriveTime / Distance as values (as shown in screenshot).
  2. Parse out drivetime and mileage for each response. 
  3. Set variables in the same DW for DriveTime / Distance
  4. Update the DW.
  5. Commit;

I know it is a gross oversimplication...Sorry.

Thanks All!!

Paul
