Hello,
I created a VB class that inhertis from System.Web.UI.P age. I set the class
to be MustInherit because I set some subs and functions to be MustOverride.
I created a webform call frmClient. By default, the page inherits from
frmClient class. In the frmClient class, by default, it inherits from
System.Web.UI.P age. So, I changed this to my MustInherit class. I
implemented the subs and functions that my MustInherit class needs to be
implement. I saved every things and run my web application and it works.
This is where the problem started. I closed my webform to work in an other
file. After that. I tried to open again my webform. My IDE threw me an
exception that tell that there are some errors in my file probably due to
the CodeBehind or Inherits attributs of the @Page directive. What I did to
solve my problem is that I removed the MustInherit attribut of my class and
replace MustOverride by Overridable to my subs and functions of that class.
It is only after that, that I have been able to open my frmClient web page.
My question is:
Why I can't implement a MustInherit class in my frmClient Class? I need this
functionality because I want to be sure that certain methods are implemented
through all my webpages that inherit from my MustInherit class.
I must missing something

VS.Net tries to create an instance of the class, which it obviously can't
because it's abstract. It does to to provide design-time support.
There's no workaround, and yes it is annoying...one solution might be to use
an interface rather than an abstract class though...

I thought about this problem over the weekend, after long hours of

potential to be useful, but I would like to hear more opinions first.
If this is deemed to be useful, I *may* try to write a PEP for it.
This is not a promise or even a proposal, at this point.

Between ClassName and Inherits, which attribute is set to specify the class
that a page uses? I would think that would be inherits. Further, the
description for ClassName is:
Specifies the class name for the page that will be dynamically compiled
automatically when the page is requested. This value can be any valid class
name but should not include a namespace.
So this is what will decidw what gets compiled? Then what is the point of...

1. Say I have three classes: A, B and C.
2. Class A can only be inherited, and B inherits it. C does not inherit
anything.
3. I have a function that can have an object passed to it. Either B or C
can be passed to it.
4. In this function, I need to determine whether the object passed to it
inherits A or not.
