Comments on: Using a Class Property to do more than just Assign or Query a Value

Or, you can test the property using: If IsError(thatProperty) Then …

In some cases, instead of using Err.Raise, you can make the property a Variant and return a CVErr(####) Object, which is less of a showstopper.

That lets you test the property value from outside the class using If Typename(thatProperty) like "Error*".

Nice article

The indentation bugs me, but I figure that's intentional.
In the case of indentation, it is better to conform, than "improve", else future development will introduce bugs.

as a rule I always get Bullen to sort out my indentation (and anyone elses for that matter).
OA LTD Smart indenter. Don't leave home without it.

Charles: There is really no such thing as incorrect or correct indenting, it is a matter of style. As long as you make your code easier to read and understand.

I don't indent the end sub's, just because I like it that way.

Tushar, I have nothing intelligent to add, but have to echo the thanks for such a well-written and concise summary.

Good article Tushar, quick question. Is your code indenting style considered the norm? Specifically, you indent the “End Sub”, “Next” and “End If” lines. I’ve seen it done both ways, which one is correct?

Yes, Tushar, thank you! An awesome lunch-time read!

One question I have is how significant of a problem is the module-level variable? Is it a matter of memory or a matter of diligently coding so as not to reuse the variable outside the Let/Get/Set properties?

Amazing article! I’ve been reading the site for awhile and this post has really clarified a lot that I’ve been trying to figure out through trial and error – thanks!!!

create article, I mainly use classes to add objects and then some maths / procedures specific to those objects.

for example on you circle, class I would an optional height and then one surface and one volume function (with the same error and data validation of course).

The thing I love about classes: its reducing the clutter in your code a lot and makes things a lot easier to understand for people reading your code (assuming that you document well your class)
