espectively. Therefor, you'll need to protect your API
  calls using a try...except block like this:<br>

  <pre class=syntax>
  var
    H: HANDLE;
  begin
    try
      H := CreateFile(...);
      if H <> INVALID_HANDLE_VALUE then
      begin
        ...
        CloseHandle(H);
      end;
    except
      on EJwaError do
      begin
        // Either CreateFile or CloseHandle could not be found, handle that
        // situation somehow.
      end;
    end;
  end;
  </pre>
