Illegal use of property: <property name>

• The target in a Get or Put statement
• The target in an Input # or Line Input # statement
• The target in an LSet, RSet, or Mid statement

You must use a variable, not a property, for any of these purposes.

This error also occurs when the property appears with a subscript as the target of an assignment statement. For example:

Dim privateArray(1 To 2) As String
Property Set MyProperty As Variant
   privateArray(1) = MyProperty(1)
   privateArray(2) = MyProperty(2)
End Property
Property Get MyProperty As Variant
   MyProperty = privateArray
End property
MyProperty(1) = "Fred"	    ' Produces error

To assign values to MyProperty, assign it a whole array:

Dim anArray(1 To 2) As String
anArray$(1) = "Fred"
MyProperty = anArray
