Trying to understand the best way to do this and I'm can't get it figured. Here's basically what I have:
Public Class CardParsingClass Private iAcctIDStart as integer Private iAcctIDLength as integer
[code]....
I've only included 2 of the class level fields here but there are actually 30, so that's why I was hoping to be able to send the name of the field to set and the value to set it at in the SetValue function. So in some other routine in the program I'd like to be able to issue the following call:
SetValue("iAcctIDStart", "3")
But then when I get into the SetValue routine, I'm not sure how to proceed. I thought about a case statement that would basically be this:
select Case strFieldToSet case "iAcctIDStart" iAcctIDStart = cint(strValue)
I have procedure (Import) that calls a for a new instance of frmImportData. I also have a class name clsBatch that has a data table property called prpParametersTable.For some reason, I get an error (indicated below with ERROR>>>) when trying to assign prpParameterTable to cv_dtImport2. The error states "Object reference not set to an instance of an object.". Why does this error not happen when I assign dtBP to cv_dtImport1? Both cv_dtImport1 and cv_dtImport2 are equal to Nothing and in my Import procedure dtBP = prpParametersTable.
Public Sub Import(ByVal clsB As clsBatch) Try Me.cv_clsB = clsB
I have three class files, accounts.vb and transactions.vb in addition to my form.vb. I am unable to retrieve a member variable from on class from inside the other. When the combobox index changes, the program loads the correct account (checking or saving) from two different sequential files. I don't think I have the calcBalance procedure in the correct class file. And that is what I am having trouble with. Accessing it to display it. [Code]
if for example i have two private sub I declared a local variable on private sub a... is there a way that private sub b could use the variable created on private sub a? Im asking because im in a problem in my app were using global variable is not an option to make the long story short
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
So Im iterating through the properties of a class. For each property Im iterating through a datatable until I find a column name with the same name as the property.
No worries so far, here's the isse: Once I've found a match I want to set the class's property to the value in the datatable but I'm having difficulty referencing the property as it has to be done through a variable.
Code: Dim per As New Person Dim t As Type = per.GetType For Each p As PropertyInfo In t.GetProperties
I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.
I need to build an application that could run code in private function, based on what user has selected using combobox. For example combo box has three values, One, Two, Three. If user selects one, code written under Private Function One() runs and vise versa.

I made a simple dll which holds some functions I would like to keep private, how can I protect it against other people using it? As it stands all you need to do is add it to resources and it shows all of the functions.
Public Interface IHasDateUpdated Property DateUpdated As DateTime End Interface Public Class MyClass
[code]....
Now, assuming I was referencing an instance of MyClass as an IHasDateUpdated; how would I determine the actual name of the property that implements the interface property via reflection?For example:
Dim x As IHasDateUpdated = New MyClass()
' How do I derive "MyDateUpdated" from "x" using x.DateUpdated?
give me a good resource that explains the difference between a Private, Public, Shared Functions/Sub/Variables? I normally use Public for Subs/Functions inside of Modules I call from other parts of the program. But I'd like to get more of an understanding of how and when to use them. I want as little as impact to a system that is running my programs as possible, so i guess the key here is I'm trying to just get more proficient in my coding.
As I develop code, I often want to unit test some of the building blocks of a class even if they are normally private. If my unit tests are inside the project, I can use "Friend" to accomplish this and still keep the functions private for normal use. But I would rather move my NUnit tests into their own separate project(s). How do I achieve the effe vb.net 2005?

I am trying to solve an issue in my application where the following exception is occurring: there is already an open datareader associated with this command which must be closed first. I am using TableAdapters, which maintain their own DataReaders, and everything seems to work fine unless I am interacting with one of my background workers.
In my code, I shadow the Item property of my collections so that I can retrieve the actual data from the database if needed. Here is a sample:
[code]...
Now each reference to the Item get property instantiates its own DataAdapter, so I am confused as to how the same DataReader will ever be used in this scenario. Is there something I am missing? All the TableAdapters do in fact use the same connection object, but I wouldn't think that would be a problem
I am converting an application from vb.net 2003 to 2005. I got the following warning and need help how to resolve it. withEvents variable 'PreviousPage' conflicts with property 'PreviousPage' in the base class 'Page' and should be declared 'Shadows'
I am trying to use fluent nhibernate in a MVC project. It seems the entities should have properties that are virtual and the set should be private for IDs. I use vb language. So tried using overrideable. It gives an error...
Public Overridable Property DesignId() As Integer Get End Get Private Set(ByVal value As Integer) End Set End Property
It says property cannot be overrideable because it has a private accessor.
I need to create unit testing project for my current website. The currentw ebsite si written in VB. All unit testing examples are using interface to create mock object. My current VB class does not implment any interface. Can I add interface and implement it to my current class and functions without affecting or changing codes to any pages in my website that call the functions? For examples my current class is like:
is there a way to have the Get part of a property available as public, but keep the set as private?Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.
I'd like to have a Private or Protected "Setter" for a property that also happens to be an abstract (MustOverride). I'm porting some code from C# to VB and in C# this is pretty straight forward. In VB not so much (for me anyway).
Some code...
In C#... public abstract class BaseClassWithAnAbstractProperty { public abstract int AnAbstractIntegerProperty { get; protected set; } }
[Code]....
The issue seems to be the inability to flesh-out the Get/Set specifics in the declaration.
