Pretty simple question. I'm quite certain I have the Class, method, codebehind, etc linked properly. Lot's of posts online say that this has something to do with compiling and/or dll/bin

this one has me stumped - problem is bolded Compiler Error Message: BC30456: 'Login1_Authenticate' is not a member of 'ASP.login_aspx'
[Code]...
I'm having trouble with a more complex program, so I've created a simple program to highlight my issue (see code block below). When I declare a Collection generically (like I have below) and try to call IndexOf, I get the following compiler error:
'IndexOf' is not a member of 'Microsoft.VisualBasic.Collection'. (BC30456)
If I instead declare my Collection as a collection of strings (Public mycollection As New Collection(Of String)), I then have access to the usual methods, but the .Add method then only allows a single string to be passed to it. This means that I can't use a key, which seems to be the point of a collection. Is there any way to have a general, keyed collection that can use IndexOf?

The exact error I am getting in Visual Studio 2012 is:
error BC30456: 'Dispose' is not a member of 'System.Net.Mail.SmtpClient'.
Dim SmtpServer As New SmtpClient()
Dim mail As New MailMessage()
SmtpServer.Port = 25
[code]....
This should be an obvious error. You would think I was using .net framework 3.5 or lower as Dispose() was only added as a member to SmtpClient in .net 4.0. However, I am using 4.0!In the website property pages it states 4.0. Is there somewhere else that I need to set as 4.0?

I am getting the same compile error for the forms with setview. I am thinking it concerns with listview. It highlights the public sub setview().
I am trying to read all selected items from a listbox in Visual Basic.
Dim x As Integer
Dim testValue As String
testValue = "20"
[code]....
is the code I am trying. But When I run the code, I am getting "Compile error : Method or data member not found" I guess I am missing some references to use "ListBox.Items" method right?What is the required references/library.
I have one page with two dropdownlists with different IDs and in my codebehind I have two distinct methods, one for each dropdownlist, with distinct names and handlers.BUT, in my codebehind, only one dropdownlist calls it's method - and sometimes it calls both methods! - while the other dropdownlist never calls its method.I tried cleaning the infamous "Temporary ASP.NET Files" folder I tried rebuilding the solution but the problem persists?

and then I created many array of structures, like this private arrayorder (100) as order
now i need to sort the entire xxxxxx member of the array of the structure with a function, but I dont want to use loops with arrays indexes to access the information. I want to know if there is another method to reference the array and the member of the structure to get the data.

From what I read it is a good convention to name a method that returns a boolean value with the prefix of "is" or "has". So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?
Public Class Day
Private TheDate as String
Private DayName as String
