i'm wondering if i can do this here goes.
i have a dll and i want my program to send it a string so it can return a certain number depending on the first letter of the string. a bit like creating a keycode for a user.
this is the dll code:
uses SysUtils, Classes, Dialogs;
procedure DllMessage(Sender: String); export;
in := random(9999);
ShowMessage('DLL Test #'+in);
how can i make a programs that sends a string, so the dll can read and send back a number.
