You can do this in more then one way.
I suggest you add GUI_Drawline() in window callback routine under WM_PAINT.

You can still do it that way. In WM_PAINT you can say:

case WM_PAINT:
  if (flag==1){
    GUI_DrawLine();
  }

)
End when you need your line you do this:

flag=1;
WM_InvalidateWindow(hWin);

hWin is your windows handle.
Hope this helps.
