I want to build a MVC helper function for which I pass a Entity Framework object and have it build a select. Generally speaking I tried something like this:
Public Function RenderSelect(ByVal helper As HtmlHelper, ByVal sSelectName As String, ByVal aItmes As Array, Optional ByVal sTitleKeyName As String = "name", Optional ByVal sValueKeyName As String = "id") As String
' open select
[Code].....
However, it isn't working. It would be great to have a way to do this and pass the current entity object.

I have a method called ADD in a class that connects to a database. The database class name is XDB. I also have an object named XXX in it's own separate class with properties.One of the instructions for the Button named ADD click event is:
'Call Add method passing in the XXX object
So this is how I coded:
'declare a variable X as an object instance of XXX
Dim X As New XXX[code].....
I know it's wrong since it doesn't add the XXX and the form doesn't close but I don't know what I'm doing wrong.
(New clsViewIllus).View(MyIBaseView, enumViewSolveTypes.View, Me, , True)

I have some files in vb.net that have "Option Strict Off" to allow for bad programming. When I convert to c# I use "dynamic" until I come back and fix problems, and this works in all cases But now I have this code:
Public Class ContractResults
'Big class definition
Public Shared Sub CleanCache()
[code].....
And in a file with Option Strict Off:
Public Sub VerifyResults(result as Object)
'Here, result is normally ContractResults
'first it check for that then call this:
result.CleanCache()
End Sub
In c# I use "dynamic", but a runtime error pops up when I call "static" method with dynamic reference. In vb.net, I can called "shared" sub from instance, but in c# this is not allowed
Exception:
"Microsoft.CSharp.RuntimeBinder.RuntimeBinderException"
"Member 'ContractTypes.ContractResults.CleanCache()' cannot be accessed with an instance reference; qualify it with a type name instead"
It seems I must convert code to use actual type, but then this means much rewriting of more parts. Is anyone able to show another way?I want to make sure you do not think I can use (result as ContractResults).CleanCache();Because all types that may be passed in have "CleanCache()" method, but do not inherits from anything the same other than "Object". There are many types (30!) that have this "static" method and so that is why it uses Option Strict Off?

REF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.
