Dear All,
  How to call a DLL written in Delphi in an ASP page?

  Any special installation needed on the IIS server?

  Thanks.



library CheckValDLL;


uses
  SysUtils,
  Classes, ComServ;

{$R *.RES}

function CheckVal(const ALoginID: String): Boolean; stdcall;
begin
  ///// do something....
end;

exports
  CheckVal,
  DllGetClassObject,
  DllCanUnloadNow,
  DllRegisterServer,
  DllUnregisterServer;

begin
end.

I don't know of any way to do this. ASP can only use COM objects, not exported functions from traditional DLLs.

You could construct a COM object that acts as a wrapper for your DLL function, but if you're going to do that you may as well put your CheckVal function in that COM object too...
