I'm programming an activex mappoint control in visual C/MFC... where i show the route of a truck.
I'm using addshape to show the origin and destination of the truck as a rectangle with text.... and pushpins (points) to show the journey of the truck.

I'm trying to join all the points of the journey by addlines from point1 to point2, it works fine until i paint more than 12 lines then the control hangs!

i tried with addpolyline() but i don't know how to do it with visual C because methods requires variants or arrays of variants.

Some help? thanks.

Is there a reason that you're not using the Route and Waypoint objects in mappoint?

i dont use a object route/waypoint because i dont use mappoint to calculate routes but to show the diferent locations that a GPS pass to a database and that i show in an activeX control by web.

please, correct me if i'm wrong... im a beginner im mapoint programming.

thanks!

in order to use AddPolyline you need an array of locations, you sound as if you already have your locations, could you just place those into an array and use that as reference for your line?

I covered C++ VARIANTs in:

Not wanting to do things the "easy" (and bloated) way, I avoided MFC...
