which technoloy u combind this dll .. if with .net u can use like this Hey I had gotten returning a pchar via a function in a DLL working. I'm having problems expanding on that - I need to return mutiple values and I can't seem to get the declaration down that will let me do that. For instance a DLL in D2006: function foo( P1: pchar; P2: pchar; P3: pchar ): pchar; export; cdecl; begin P1 := 'blah blah'; Result := 'Blah2'; end In C#: [ DllImport ( fooshell.dll )] public static extern string foo( string P1 string P2 string P3 ); Calling this function will properly return 'Blah2' as the result but does not change P1. What's the trick to pass like a 'var'?
