need info mappoint/gps/vb6 developement
i have created an app. in vb6 with mappoint control for car navigation
i read the com port on which the gps antenne sets its data.
the user can type in a destionation location and the gps location is used as start location. if show the first element of the directions collection to the user (driver). after 2 seconds i do a complete recalc whereby is set the start location to the new gps location. again i show the first element of the directions collection to the user.
this can't be the right way to go (cause for e.g. what if 2 or more directions are needed within the 2 seconds refresh rate i use)
but i can't figure out how to go if i keep the start location fixed.
Q: how to go on with the gps location and the directions. what direction element has to be shown?
Q: what if the driver is lostand far off-track? how do the 'fixed' set of directions help in any way?
Can anyone point me out how the program flow goes?
Do i have to recalc over and over?
How do i know of an refresh/recalc is needed during runtime?
Don't need exact coding bus samples are always welcome.

In-car navigation with MapPoint (in EU)
Thanks a lot for your reaction. This was the kind of input I was looking for.
A few questions on your reaction came up:
1. has Destinator got european maps (Belgium / Netherlands / Luxemburg / Germany)?
2. Autorotation is something I don't bother much, I search trough the second direction element for words like: left,right(etc),bear,first(etc),roundabout and show a picture I have drawn for that.
3. @"recalculating routes on a highway.." what is meant by: "(non-)limited access roads". :confused: It might sound dumb but i havent got much of a clue...and english isn't my native language at all. Is it "Limited" like limited for distinct user groups say like bicycles etc.?
