As well you should have a look here, it might help if your trouble is elsewhere .. Forms in dll

Answer 2

here's something i've found necessary to do this. see my example function below:

procedure DoSomething(hApp:THandle); export;
var
  hDllApplication:THandle;
begin
  hDllApplication:=Application.Handle;
  Application.Handle:=hApp;
  try
    DoItNow;
  finally
    Application.Handle:=hDllApplication;
  end;
end;

You are dereferencing a nil pointer somehow. Perhaps an object that hasn't been created?
