.net - Create A Variable Of An Instance Object Of A Class At Runtime?
Sep 29, 2011I am trying to create new variables inside a class after creating its object at runtime. The problem is that I don't know the variable names or the value beforehand so I have to create the new variables at runtime.
[Code]...
This is a more elaborate explanation of my code. If you observe that in the Eval function I have tried to evaluate Fval(abc). Now the object array abc is not declared in the Test class because it existence is not known beforehand. What I want to do is create an object array abc of length 2 and populate it with some values and when Fval(abc) is called then then the value of index 1 should be the return value of Eval fucntion.

Check If Variable Holds An Instance Of Class?

View 3 RepliesClass-level Static Variable Per Instance?
Jan 28, 2010I need a static variable to get a ListItemCollection from a List control (I can do this, but if I don't set it as Shared It's not preserving the values as it should). The thing is that this class is a SharePoint webpart, so I most probably will be using the webpart more than once, and I need this variable to be unique to each webpart, which shared doesn't accomplish.I tried everything you can imagine. I placed a Static variable within a Sub (shared and not shared), I tried it with Properties (also Shared and not shared)...

.NET : Runtime Is Initializing A Variable To An Instance Of The Wrong Class?
Jul 26, 2010I've got some code that looks like this:
If ediFileGroupAbbr = "NIPDSINV" OrElse ediFileGroupAbbr = "WWPDSINV" Then
Dim p As New PrivateBillingAdapter_ForN(ediFileGroupAbbr, businessLocationID, mode, EDIJobItemLogID, BusinessUnitID)
Return p.ProcessEDI(True, False)
ElseIf ediFileGroupAbbr = "FOPDSINV" Then
[code]...
to which I'm passing in a value of ediFileGroupAbbr = "FOPDSINV". But the code is executing as if it's dropping into the third condition (p is a PrivateBillingAdapter). So I've stepped into the code and, sure enough, it drops into the second condition. BUT, if I step into the execution of the constructor, the debugger jumps to an odd place in the code - sort of the middle of a method and not on any actual line of code.A couple clicks and it hops back out of the constructor, still in the second block of code. But if I mouse over the variable p to see it's type, boom, its a PrivateBillingAdapter (from the third block).Like I said, something is clearly wrong but I don't know what. I've tried rebuilding several times but with no new results.This is VS2003, framework 1.1 with VB.NET.
C# - Access A Shared/static Member Through An Instance Variable?
Mar 3, 2011Here's an example of what I'm talking about...
Public Class Sample1
Public Shared Function MyValue() As Integer
Return 0
End Function
Public Sub Code()
[Code]...
Me.MyValue gives a warning in VB.NET and (the equivalent code gives) an error in C#. Is there a particular reason for this? I find it more intuitive/natural to access the shared function using 'Me.MyValue' - but I avoid it to keep my warnings at 0. Did someone else just decide 'Nah, it makes more sense to do it the other way' or is there some technical reason I don't understand?
EDIT: I was thinking of it wrong, more like a 'sub class' in OOP. Even if something is declared in the base class, you access it through the instance you have. But that relationship is not the same with shared or static.

C# - .NET Generic Class Instance - Passing A Variable Data Type
Jun 2, 2010I'm tyring to pass a variable data type to a template class. Something like this:
frmExample = New LookupForm(Of Models.MyClass) 'Works fine
Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine
frmExample = New LookupForm(Of SelectedType) 'Ba-bow!
frmExample = New LookupForm(Of InstanceOfMyClass.GetType()) 'Ba-bow!
[Code].....
I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either.

Dim NewPanel As New Panel1
Is not working. When you create an instance like this, the "Panel1" wont show up in the list of classes, so it says "Panel1 is not defined".I have heard of control arrays dissappeared in VB2008,but still,is there any way to create a new instance / copy an already existing control or let a control appear like it was when you made it in VB so you can open multiple Panels like they are child forms?
EDIT: I know you can do:
Dim newPanel As New Panel
newPanel = Panel1
Form1.Controls.Add(newPanel)
..but that's not what I want, because that makes you can't edit the controls inside the new panel.

Create An Instance Of An Object/webpage?
Jun 7, 2011if i create an instance of an object/webpage, is that a complete new object/page based on the original or does it does it just make it accessible? i am almost sure that it creates a new object/page but i would like confirmation. in other words what is the result of this code?
dim Page2 as new Page1
dim Page3 as new Page1
would this create 2 new pages that i can "customize" separately and add different controls to each? heres a brief description of what i want to happen:the user will be viewing Page1 and when he clicks btnCreate i want a page that i created in the designer to be shown and its name and other variables to be determined by what the user chose for room options in Page1. i need "new versions" of this page to be created because multiple users will be creating multiple rooms. i understand that there are more lines of code involved in creating pages and i do have more questions regarding those but i will wait until i confirm that dim Page2 as new Page1 will create a new page. like i said im sure that this does create a new page but i need confirmation. also if it does create a new page, how do i get it to show. i know that response.redirect will redirect me to a dif page but i want show this new room on top of the old one.

The author asks for the user to create a solution with two projects, one winforms and the other a class library (called DependentAssm). The class library is added as a reference to the winforms project In the class library, he asks one to create a new class called SayHelloComp. The project created a file called class1.vb, and a class called class1 which I renamed to SayHelloComp. I left the file name alone, that's ok right?
View 4 RepliesHow To Create New Instance Of Web Service / Config
Sep 2, 2010So I get thrown an exception right when I try to create a new instance of my Web Service that says:
"Could not find default endpoint element that references contract 'KBBVehicleService.IVehicleInformationService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element."
This is a web service that will connect to Kelley Blue Book. I know I need a new endpoint entry in my Web.Config, but what does this look like? The one I added looks like this:
<endpoint address="http://localhost:3300/KBB.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Default" contract="Services.Client.IVehicleInformationService"/>
But it doesn't work. Still throws the same exception at the same place.
