VS 2005 Class Declaration?
Jun 8, 2011
I have two classes; one is a data class which contains routines to handle data and the second is a utility class which contains useful routines which can be used again and again. I have come across a problem. Some of my routines in the utility class use routines in my data class and now I want to use some of my utility routines in my data class. I tried this in a service and the service just would not start. After commenting out code I realised it was because I was making a declaration in the utility class for the data class and in the data class making a declaration of the utility class.
I understand that this is now causing looping but is there a different way to do what I want. If not I would need to have two copies of routines in both classes.

In the code below, when I use the same interface with O in the Class declaration line and the Inherits line, I then get a compiler error when I access the interfaces Year member in both the properties. It says " 'Year' is not a member of 'IRegionYear'." I get the same thing if I use the same class with each Of.
I don't get this error when the interface or class entered for both Of clauses are different.
Interface IRegionYear
ReadOnly Property Year() As Integer
End Interface
MustInherit Class RegionYears(Of IRegionYear)

I'm a newbie to VB, and I am having difficulty understanding what the following (legacy code) class declaration actually means:
Public MustInherit Class ModelBase(Of T As {ModelBase(Of T, TIdType), New}, TIdType)
There is also a related ModelBaseCollection:
Public MustInherit Class ModelBaseCollection(Of TCollection As {ModelBaseCollection(Of TCollection, TModel, TIdType), New}, TModel As {ModelBase(Of TModel, TIdType), New}, TIdType)
Inherits Collection(Of TModel)
I have difficulty understanding the need for the ModelBaseCollection class as the ModelBase class is a generic type.

Consider the following class:
[Code]...
In the Sub New(), technically you can pass in "Nothing" for one of the parameters, or string.empty for the string. My question is how do you force the class to not create itself? Oh yes and I know you technically are not supposed to use IsNothing() in .Net however "OrElse MyPar2 Is Nothing" generates an error.

I am a java developer that inherited a vb.net web application. This app relies on a VB class assembly that builds in to a dll. I have made some changes to this class assembly but I cant seem to get the vb.net app to pick up the changes. I thought that using regsvr32.exe or regasm.exe would do the trick but after reading a bit more they don't appear to do what I need.
When vb.net uses code such as this import where is it getting the reference to "MyClassName"?
<% Import namespace="MyClassName" %>

I want all my form to be inherits from one of my class e.g.ParentClass but indeed the windows forms already inherits windows.forms.form class. what I have tried is that, I inherit "windows.forms.form" in "ParentClass" and all forms inherits my "ParentClass". But in this case when I view the design of the form IDE gives error.

I can't seem to figure this out. I basically am trying to write a class, not a usercontrol, that can show up in the ToolBox. I want it to act similar to how a ContextMenuStrip or BindingSource does, in that there is no UI when you throw in on the Form, it goes down to that bottom part (name?).
1) What do you call those types of components?
2) Why won't this test class that I wrote do the same thing?
vb.net Imports System.Windows.Forms
Imports System.Runtime.InteropServices
<ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch), ComVisibleAttribute(True), _
System.ComponentModel.ToolboxItemAttribute(True), System.ComponentModel.DesignTimeVisible(True)> _
Public Class FilterMenuStrip
[Code]...
If I try to add it to the ToolBox, I get a "There are no components in '<The DLL>' that can be placed on the toolbox."

What I would like to do now is well convert this somehow to a class. so I do not have to DirectCast the items. Is this possible?
Here is the original code that kleinma assisted me with:
Dim CtlLosArray(150) As ShieldLOSInfobox
CtlLosArray(0) = New ShieldLOSInfobox
CtlLosArray(0).Location = New Point(0, 0)
[code]....
Is there a way to make this into a custom class so that I can make things easier to manipulate? at least that is how I think it would be done.

Can you raise events from a class that has only shared members and doesn't get instantiated? I originally had the class members non-shared and created instances of the class where I need them. I had the events being raised and everything worked as expected. But as the class members are actually application level and do not need instancing, I converted all members in the class to shared so they could be accessed from anywhere in the program without creating an instance of the class. But WithEvents requires the creation of a class instance. I've done that and it seems to work fine when using an instance. And since I need the events handled in only one class, I can create the instance in that class and let all other areas access the class directly, without creating an instance.

I am trying to copy an Array(of Class) to another Array(of Class). The Class really just holds 3 values together, so it's basically a string. I thought just something like this would work
[Code]....
But that literally makes Array1 access the contents of 2, but I want it to be a separate copy. I'm currently using a simple loop procedure to copy contents but I was hoping there was a command for it. I looked at .Item but there didn't seem to be anything there.
