I have a session class that basicly just sets and retrieves session variables, the reason I made it was so I could easily change it to use sessions or something like memcache to set the items and have them accessible on multiple pages without hitting the database I then have this user class which uses the session object to get session v...
Is it possible to get the enum value of a base class, from a derived class, without using reflection ?

I want to define classes in Python, but I'm currently putting them in modules, contained within packages. Is there a cleaner way of doing this? Is it okay to define classes in __init__.py of the package itself? I'm still learning how to arrange my Python source code, but this seems to be creating a slight ambiguity? Thanks to all! ...
class FormatFloat(FormatFormatStr): def __init__(self, precision=4, scale=1.): FormatFormatStr.__init__(self, '%%1.%df'%precision) self.precision = precision self.scale = scale def toval(self, x): if x is not None: x = x * self.scale return x def fromstr(self, s): ...
From my studying of python, I've found two uses for %. It can be used as what's called a modulo, meaning it will divide the value to the left of it and the value to the right of it and spit back the remainder. The other use is a string formatter. So I can do something like 'Hi there %s' % name, where name is a list of names. Also, if y...
I have a factory that is supposed to create objects that inherit from class Foo at run-time. I would think that System.Activator.CreateInstance's return type was the same as the type of an object it's creating, but judging from the following error message, its return type is Object. Error 1 Cannot implicitly convert type 'object' to ...

Hi, I am trying to assign a theme based on browser type. I would like to do this in a base class so it would only need to be in one place (I am using a master page). I coded the following but the "OnLoad" here is performed before the "Page_PreInit". This needs to go in Page_PreInit, but why isn't it firing? Imports Microsoft.VisualB...

May be getting the date of last modification ...
