I have a canvas class that has a few methods and properties
assigned to it
One of those properties is a Picture (showPict)
One of these methods is orient1To1_8 which takes one parameter
a picture which I am passing by reference
Method Name: orient1To1_8
Parameters: ByRef anyPict As Picture

orient1To1_8(Me.showPict)
This line of code makes the compiler object:
Error Message: "You cannot pass an expression as a parameter that
is defined as ByRef.
orient1To1_8(Me.showPict)
Why is a property considered "an Expression"?
______________________________
If I define a variable and go through the steps of assigning the
property to that variable
Passing that variable to the method
Then assigning the variable to the property the compiler is happy
and things seem to work
Dim anyPict As Picture
anyPict = Me.showPict
orient1To1_8(anyPict)
Me.showPict = anyPict
After reading Charles' response, i wonder if 'orient1To1_8(showPict)'
would work? Both method and property are contained in the super.
