Yes I used the great circles distance formula, I hope Guino adds this to RR, and provide 3 or 4 counter labels, then we can each use the information the way we want too.
Guino can probably shed more light on how hard it will be but he is already reading the raw gps information. I did all the maths (about 6 lines of code) in one function so it would be easy for Guino to copy. It will only need a bit of a syntax change to make it work in VB. AutoIt and VB code is very similar especially the all the trig functions.
Add Counter1 Counter2 ……as new RR labels
add 4 command
start counter#, stop counter#, Clear Counter#, counter direction# (EG count up or down)
While it works in Autoit passing labels back and forward between AutoIT and RR just uses extra CPU which most people hate
Then we can each use the Counter labels for our own needs, like you say use it your GPS Gasoline app.
I imagine that a few like Tissy and DiNASTY will do flash trip meters, if we can get this to fly
Also thought that Chuck would want one for his Truck, if he doesn’t use it to keep track of distance he can always use it to count his RR variables
