You can create Property Let, Property Set, and Property Get procedures that share the same name. By doing this, you can create a group of related procedures that work together. Once a name is used for a Property procedure, that name can't be used to name a Sub or Function procedure, a variable, or a user-defined type.

The Property Let statement allows you to create a procedure that sets the value of the property. One example might be a Property procedure that creates an inverted property for a bitmap on a form. This is the syntax used to call the Property Let procedure: 

Form1.Inverted = True

The actual work of inverting a bitmap on the form is done within the Property Let procedure: 

Private IsInverted As Boolean Property Let Inverted(X As Boolean) IsInverted = X If IsInverted Then … (statements) Else (statements) End If End Property

The form-level variable 

IsInverted
stores the setting of your property. By declaring it Private, the user can only change it only using your Property Let procedure. Use a name that makes it easy to recognize that the variable is used for the property.

This Property Get procedure is used to return the current state of the 

Inverted
property: 
Property Get Inverted() As Boolean Inverted = IsInverted End Property

Property procedures make it easy to execute code at the same time the value of a property is set. You can use property procedures to do the following processing:
