How can I show the directions on a Polyline

Hi,

I have to show a driving route of a vehicle based on  latitude and 
longitude.
There are about 8000 Points to show in the map. ( it's only one day to 
show )

I use getlocation with lon and lat to get the direction-array and then 
addpolyline to show the line.
Thats not the Problem, but I have to show the driving-direction at some 
points ( e.g. in a distance of 300 m ).
I tried to use add line with line.endArrowhead, but this is very very slow. 
it is about 3 minutes of time to schow the route.

Is there any fast solution to show the directions? It can be shown at every 
point too. ( if there is any property to set at the directions )

Thanks in advance

Regards,

Christian

"Directions" is a bit ambiguous in English and in the MapPoint context
as it
could mean "driving directions" - I guess your intended meaning is
"Fahrtrichtung" here?

If yes, here's an idea: indicate the direction using a pushpin placed at
strategic intervals? You could either use the 45° predefined symbols, or
design your own custom symbols with a finer rotation resolution.
