The Hide method makes an open window invisible.
• window – A window object.
Use the Hide method to make any open window invisible. While invisible, the window is open (its IsLoaded property is True) and data in the window is still accessible. Use this method when you want to reference data displayed in a window without making the window visible. You can also make a window invisible using its Visible property (window), or by using the OpenVisible parameter of the window’s BeforeOpen event.
