Haven't done much of this before. I am trying to use a dll with a function definition of:
Long _stdcall TransGeogPt(LPSTR psGridFile, long lDirection, double dLatitude, double dLongitude, double* pdLatNew, double* pdLongNew, double* pdLatAcc, double* pdLongAcc) I have translated this as: function(psGridFile: PChar; lDirection: Integer; dLatitude, dLongitude: Double; pdLatNew, pdLongNew, pdLatAcc, pdLongAcc: PDouble): Integer; However trying to use this function I get: Access violation at address 77C43B4C in module 'MSVCRT.DLL'. Read of address 00000000'. Any ideas? Have I translated wrong? Cheers, Dave. _______________________________________________ Delphi mailing list [EMAIL PROTECTED] http://ns3.123.co.nz/mailman/listinfo/delphi
