.net - Using A Class Like A Public Variable In Asp.net?
Apr 13, 2009
I'm getting an error in .net when trying to declare a Public class on my code behind page.
Partial Class _Default Inherits System.Web.UI.Page
Public someVariable as integer
Public someClass as className
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load [...]
The error I'm getting is BC30508: 'someClass' cannot expose type 'className' in namespace '<Default>' through class '_Default'.The goal here is accessing the class properties in script blocks on the aspx page like this <%=someClass.classProperty%>
I'm not sure if I'm trying the right methods (I've tried several ways of declaring the public class) or if it can even be done..

I want to created a nested class that can only be visible to and instantiated from the parent class.But I also want to be able to use an instance of the nested class through a public variable of the parent class.I tried making the nested class private, or making the nested class' constructor private, but it won't compile.Is it possible to do this in .NET?

I currently have two forms, and I need to share the value of a variable in one of them.
I declared the variable to be 'Public Shared', and assigned a value to it. However,
when I inspect the value it appears as 'Nothing'. Here is the snippet:
Public Class A
Public Shared sVar As String = Nothing
Private Sub A_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Is it possible to set a variable in my custom class for Private Read/Write access and Public Readonly access without creating Properties with Get and Set? In other words, from within my class I want full access and from my form I only want read access. Right now I declare my variable as either Private or Public to control Public read/write access. I tried googling my question a bit but I'm not sure what the correct terms even ar

I have an arraylist in a user form (Mainform) that I would like to be able to share among multiple forms and edit the contents. Using the Public Shared method I have been able to view and even edit the arraylist, but it does not seem to be changing it back on the main form. I can give more detail if needed.

I have a public variable which seems to be going out of scope. I am confused as it has been dimensioned as a public variable: Public xlCell as As Microsoft.Office.Interop.Excel.Range
I originally had all my code in the same module in the same project and it was wrapped within a For/Next Loop (Example 1). I decided to clean up my code and make it more modular (Example 2). All the code is still in the same module in the same project.
Upon doing so, my public variable is not recognized in any of the private subs that I have created. I keep getting the following error: Message="Object reference not set to an instance of an object." When I test the variable using ?IsNothing(xlCell) in the Main Sub I get False in the main sub. this tells me te variable is recognized. However as soon as the Call SelectCaseSub() is triggered, I get a True value for ?IsNothing(xlCell). Why is this? Shouldn't this variable be in scope regardless?

The query will be formatted something like this:

I have a public readonly variable in a module, but when I try to set it in my form load event for the first time I get 'ReadOnly' variable cannot be the target of an assignment. It is my understanding that a ReadOnly variable can only be set once and after that you would get an error when setting it.
