  Just a tip: if you want to define a function where you are not going to modify the results or when you do not know the number of parameters or the type (or are just too lazy too declare them all ;-) you can declare it like this:
  
  var
  FunctionPtr: Pointer;
  
  GetProcedureAddress(FunctionPtr, 'my.dll', 'SomeExternalFunction');
  
  procedure SomeExternalFunction;
  asm
  jmp dword ptr...

  I think this is a Delphi bug, I remember it because I had a problem with some other winapi call that returned an interface.

  function Direct3DCreate9(SDKVersion: Cardinal): IUnknown; stdcall; external 'd3d9.dll';
  
  procedure TForm2.Button1Click(Sender: TObject);
  var
  Unknown: IUnknown;
  begin
