How to send message to delphi application or ocx

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'?
