Re: NotSupportedException TomTomSDK

Tech-Archive recommends: Speed Up your PC by fixing your registry

Ok, that indeed does the trick.

One more question:

TTNCom_GetLocationInfoV01( long aLongitude, long aLatitude,
CTomTomNavigatorCom::TLocationInfoV01 &aLocInfo );
where the Locationinfo parameter is an structure:

struct TLocationInfoV01
{
int iType;
TCHAR iStreetName[128];
int iHouseNr1, iHouseNr2;
};

Any ideas how to declare the TCHAR? (or should i use an other datatype?)

Declaration
[DllImport("TTNCom.dll", EntryPoint = "TTNCom_GetLocationInfoV01",
SetLastError=true)]
public extern static int GetLocationInfoV01( int aLongitude, int aLatitude,
ref TLocationInfoV01 aLocInfo);
