Passing 'this' to a function
I would like to create a class that changes some basic
attributes of a web page based on values in a database.
Things like background color, font, text color, etc. My
problem is that I'm not sure how to pass the
variable 'this' to a class function. I need to be able
modify the properties of the controls on the web page.
Has anyone done something like this?
Thanks for the help!

I believe your problem lies in the fact that your function defines the
parameter type as a reference to the Base Page class, rather than a
reference to your inherited Page class. The types don't match exactly.
