I need to write some software in VC++ 2005 to calculate driving distances between between two addresses for many pairs. I have done this in vb successfully but The project requires me to do so in vc++. I have little experience in vc++ and need to find some code examples especially around importing the mpna83.tlb file. I have found a few examples using older versions of vc++ but i am missing something because I get 'undclared identifier' errors when I compile the code - even though they are defined in the tlb file. Any help would be appreciated.
