Botón de minimizar y maximizar en Form de vba

En base a una pregunta del blog, encontré el siguiente código (el cual no es mi autoría) para poder poner tanto un botón de minimizar y uno de maximizar en un formulario de vba.

El código va en el formulario. Lo comparto:

    Botón de minimizar y maximizar en Form de vba

    No se puede descargar el ejemplo, da el siguiente error el link de descarga:

    Runtime Error
    Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

    Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a “web.config” configuration file located in the root directory of the current web application. This tag should then have its “mode” attribute set to “Off”.
