I'm sure there is a limit, but I haven't run into it yet. All I did when developing this routine was to look at the Chrome URL string that was built by the Google Maps website. Essentially they just build a string that is combined with "to:"
Here's some pseudo-code (not sure if this will come through the list okay) lcStartPoint = "123 W Main, Yourtown, FL" lcURL="http://maps.google.com/maps?f-d&source=s d&saddr=" + lcStartPoint * build the string out for each stop along the way for lnum=1 to numberofaddresses lcURL= lcURL + '+to:' + <<insert next address string here>> endf * finish with a return to our origin point lcURL = lcURL + '+to:' + lcStartPoint DECLARE INTEGER ShellExecute IN SHELL32.DLL ; INTEGER nWinHandle, STRING cOperation, STRING cFileName, STRING cParameters,; STRING cDirectory, INTEGER nShowWindow lcRunWith = "chrome.exe" lnError=ShellExecute(0, "", lcRunWith, lcURL,'',1) The above pops Chrome open with a total route map that starts and finishes at the same place. Drivers usually don't want or need the actual "turn here" instructions, so the value is primarily in the distance and time estimates...at least for my needs.
