CalculateRoute : No data

[Fdumaine]

Hi!

I need help. I try the code you can find after. But i have a message :
There is no route data available in the region of the world where the
destination is located.

Can you help me ? What i need to do ? I just want Calculate the route
between 2 positions.

Thank you

François

1) Did you remember to use "Add Service Reference" instead of "Add Web
Reference" in Visual Studio 2008? (Will not work properly in VS 2003 or 2005)

2) If yes to 1), then you will need to make a RouteServiceClient instance to
make the call, e.g:

RouteServiceClient routeService = new RouteServiceClient();

Hope that helps,
