Specifying Different Page Base Classes For Different Directories In Web.config File?
Mar 17, 2010
I have a website (coded in vb.net) with an "admin" section (the admin section being a folder in the actual site)... So in every page of the site I'm using my own custom class as the page base (which has been set in the web.config file) but I want to inherit from different class for the files in the "admin" folder... Is there any way to inherit different classes for pages in different folders using the web.config or some other equally as global method? (meaning some other way than inheriting on a per page basis.)

I have classes setup similar to this:
<DataContract()> _
Public MustInherit Class SystemTaskProcessBase
Public MustOverride ReadOnly Property Name() As String
Public MustOverride ReadOnly Property Description() As String
Public MustOverride Property Result() As SystemTaskResult
[Code]...
I need to use these classes on the client system, but also need to be able to create these "tasks" through a management interface. Each class (Task) that inherits the base, could have its own properties that are unique to each class, but at the same time, share the same common base class properties. For example, the above shows a reboot task and a delete file task, the delete file task needs to know which file to delete, so has a property for that. But the reboot task does not need this property. So when the management application is creating these tasks, it shouldn't provide a text box for the file property for the reboot task. There may be more tasks created at a later date with completely different properties.
How would I go about providing the WinForms management application a way to enumerate each class into a ListView for example, and allowing the user to create these tasks and filling in the dynamic properties that each class would have? Desired functionality would be to create a task form that creates dynamic controls available for the properties as needed, depending on the public properties in each class, but at the same time have the base class properties available as well.

I have a webservice that is wrapped up by a data access object and is accessed by many different UI controls.
The proxy objects look something like this:
Public Class WebProxyObject1
' Common properties, there are about 10 of these
Public Name As String

I'm trying to create a base interface for a class of mine that uses generics. However, I cannot figure out how to declare a property of the interface when its type won't be defined until the class is initialized.
To clarify, consider List(of T), which according to msdn, implements IList (among other things). Note that IList is not the same as its generic counterpart IList(Of T). So that mean any List(of T) can be converted to IList, which simply returns an object for its items. That's what I want to do with MyClass(of T), be able to cast it as IMyClass regardless of what T is.
But when I try such as:
Interface IMyClass
Prop A as Object
Class MyClass(of T) Implements IMyClass
Prop A as T Implements IMyClass.A
I get a signature error for the last line, even though object is broader than T. What am I doing wrong, or how exactly did Microsoft manage to make List(of T) implement IList?

I have a web app that has a base page.Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights.My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed.On the init of each page I set the properties "Role1Allowed" and "Role2Allowed".[code]Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was?As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it.Is there any way to force them to do this?

i've finally got round to learning about classes and inheritance, but i'm not sure how to proceed. i have a base class Employee, which is inherited by 2 derived classes. how do i use the same Employee class in both derived classes? obviously if i write a sub new for both of them + declare a new Employee class, they won't be using the same class. heres my Employee class:

I have written multiple programs in the past that deal with cad data. Points, lines, arcs, etc. For each program I ended up creating slightly different versions of some really base classes like a class that defines a point:
<Serializable()> Public Class Point
Public x As Double = 0
Public y As Double = 0
Public z As Double = 0
End Class
My question is how would I use that class in such a way that it could be in a namespace and imported into any future project that I write?

Background:I have a base class and several inherited derived classes. The derived classes don't always need to have the same properties. If any properties are shared among the derived classes, those properties would live at the base class level ('Contents', for example).Similarly, GoodDocument below has 'GoodThings' but would not want/need to have 'BadThings'.I want to treat instances of both 'GoodDocument' and 'BadDocument' as type 'Document'
public mustinherit class Document
public property Contents as string
public sub new()...

I have a base page class that inherits from Page. We'll call it SpiffyPage. I also have a user control called SpiffyControl. I then have an aspx page, ViewSpiffyStuff.aspx, that inherits from SpiffyPage. On page load, the SpiffyPage class is supposed to inject a SpiffyControl into the aspx page. The problem is that SpiffyControl is a user control, and to instantiate that in the code behind one has to access the ASP namespace, sort of like: ASP.controls_spiffycontrol_aspx MyControl;
But SpiffyPage isn't an aspx page, it's just a base page, and as such I can't access the ASP namespace, and I therefore can't instantiate a SpiffyControl in order to inject it. How can I achieve my goal?
Edit: One important point is that I must have a reference to the actual control type so I can assign values to certain custom Properties. That's why a function like LoadControl, which returns type Control, won't work in this case.

I have 3 vb classes and I am trying to add them to my aspx vb page. I try to do
Dim Class1 as new class1 but only one of them works, the other 2 do not work. I made a sample class and put the following in it:
Public Class test
Public Sub test (byref test as string)
test = 5
end sub
End Class
Then I went and tried to do Dim test as new test but it doesn't work, what am I doing wrong? The other class works fine and I don't know why this one wouldn't.

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.
