Overload Method To Existing Public Class?
May 8, 2009
I have written a method to replace multiple characters in a string. Is it possible to overload my own method to the existing method "Replace" in the String namespace?
Function Replace(ByVal inValue As String, ByVal ParamArray replacechars() As String) As String
For i As Integer = 0 To UBound(replacechars) Step 2
[Code].....
As you can see it have a different signature from the public method so I think it would be nice to have my method overloading the existing method
I can live with it if it isn't possible. See it as a "nice to have"

Suppose that I want to implement another method for a class namely hasFiles for System.IO.Directory , How can I do that?
for example if I add <Extension()> _ tag before each function or Sub I can add a new function or method for each Control.

what websites, books or courses you guys suggest to use so I learn the fundamentals of programming. What is a class, method, namespace, private vs public. That leads me into .Net programming. A lot of intro to programming use java or C++ as the platform but I want to find one with VB.net or maybe C# if.

I'm implementing following code in VS2010:
If xl.cells(1, contacolonna).Borders(Excel.XlBordersIndex.xlEdgeRight).LineStyle <> Excel.XlLineStyle.xlContinuous Then
MsgBox("hello")
End If
or following

but in both cases VS returns following error:"InvalidCastException was unhandled Overload resolution failed because no Public '=' can be called with these arguments:'Public Shared Operator =(a As String, b As String) As Boolean':Argument matching parameter 'a' cannot convert from '__ComObject' to 'String'.

I am working on this project and I am suppose to overload the method to allow strings instead of integer. Allow the user optionally add a thried string from a third text box. Okey I am trying to under stand this good. This is the code I have:
This is my overload class
Public Class OverloadEx
[CODE]........................
So with my overload class instead of integer I should put string there? If the user clicks the add button it will allow the user to add all 3 text boxes but when the user click the add string it will allow the user to add all three text boxes to string. So do I click the add string button to overload it to that one just like I did with the add?

Is there anyway to add an overload "extension method" to a method that already has one or more extension methods?For example theString.Contains method has two extension methods totalling 3 separate versions.Is there anyway to add an extra extension method also called "Contains" ?By the way I have tried it but the IDE does not seem to recognise additional EXTENSION methods where a method already hasone or more extension methods.Is there anyway around this restriction?In other words I would like to be able to change the Extension method below from"Contain" to "Contains" but it seems it is not recognised.

EDIT: The above class is just an example of what could be returned from a web service. I won't have access to modify it at all, sorry if I didn't make that clear.Is it possible to somehow make a clone this class, so that it retains all of the properties values, but hides the fact that there is a Public function?I'd like to be able to take some existing classes we retrieve from a web service(which we didn't write) and be able to pass them on for use in an application, but without exposing the functions. I don't want to go down the route of creating my own classes that specifically define each property and write the values in (due to the sheer size of some of them), so I'm looking to see if there is anything dynamic I can utilise (maybe there is a way using reflection?).

I want to created a nested class that can only be visible to and instantiated from the parent class.But I also want to be able to use an instance of the nested class through a public variable of the parent class.I tried making the nested class private, or making the nested class' constructor private, but it won't compile.Is it possible to do this in .NET?

I'm working through a book that does not provide a lot of example code and what it does provide is in C#. The book refs vs 2005 but I'm using vs2008. 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?

I have a windows service that I have been writing in Vb.Net. As part of this service it calls a class that has a long running Process.I can execute commands to this process when I want to via the ServerCommands() class within the service, however I want to call these remotely. Possibly from a website or click once WPF application.
For this I have used a simple Tcp.Ip WCF example, and have verified it as working correctly.
This called OnStart()Private _serverCommands As ServerCommands
Protected Overrides Sub OnStart(ByVal args() As String)
Add code here to start your service. This method should set things
in motion so your service can do its work.
[Code]...
It appears that in debug _serverCommands is Nothing when it should be running.How might I go about ensuring any command I execute through WCF communicates with the running instance instead of creating a new ServerCommand() instance??I haven't tried WCF before, so I might be hitting a dead end... however I'm sure its possible.
