I have two classes:
Public Class Subscribing
Private _subscribingObjects As IList(Of String)
Public Sub Add(ByVal obj As SubscribeObject)[code].....
Is there a more elegant way to add do this? One class would suffice, but since the Add methods have different arguments, then one really wouldn't work.
I need to generate a class at runtime similar to System.Resources where you can add a resource eg 'picture.bmp' and it immediatelly is accessible as 'System.Resources.picture.bmp'. I presume I need to generate XLM or/and XLSD at design time and then deserialise at runtime but I cant find a reference on how to do this. Specially without knowing the generic class in advance (as 'System.Resources' doesnt know all the resources in advance).
View 4 RepliesWe have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.

View 2 RepliesI'm looking for a library compatible with microsoft.net framework that allows the creation and verification of XAdES signatures (XAdES, XAdES-C, XAdES-XL, etc...).It is important that the library enable the programmer to choose:
1.- Type of certificate to use in the signature process (PFX file, Windows centralized store, SmartCard)
2.- CRL to validate the certificate.
3.- Possibility to include Time stamping on the signature.
4.- Possibility to include OCSP response on the signature.
All I found are libraries in Java, but have not found any libraries in .NET.

I added a table to my program and it generated two errors and not it will not build. I have added quite a few tables and this has never happened before. The reeors are:

I have deleted the table that I added and tried undoing everything having to do with it but nothing works.

I have a number of unrelated subs and functions that do various things on my server (e.g. Lighting control, data caching, server maintenance, etc). They are all in various classes which I have coalesced into a single solution.My goal is to create a single, simple interface which each of these disparate classes can be integrated and called from a command line interface. Instead of hard-coding a longish case statement which parses arguments and passes them to the various subs, I wanted to make a generic class which can be instantiated with a minimum of information and put into a data structure. Ideally, adding a new function would involve:
1.) Providing the function pointer (Delegate). The delegates will have various signatures. This is the crux of the question.
2.) Providing ancillary info such as the command-line callable name, number of arguments, argument types, etc.
I have a 100% working class called "node" which is basically a hierarchical tree of node instances. I can use this to simply organize function calls in related branches. All is working quite well.NodeFunctionDelegate(ByVal args As String) As String.The node takes the arguments passed to it by the command line and sends it as the "args" string as comma-separated. The delegate function then needs to know how to split up these comma-separated values, type them, tryparse them and etc. It then must return some string.It works, but it involves writing a middle-man function stub which can receive the argument string from the node class, do the parsing and type checking, and then call the destination function.My goal is to eliminate this trivial middle-man function. The problem is, I can't figure out how to create a variable-signature delegate for the node class.

I am having a problem setting up automated email signatures for a company through VBScript. Everything works fine apart from the rich text file creation. In this section for some reason a double underscore (__) always appears at the end of the e-mail signature when a user has their outlook set up for rich text. As you can see the script creates the signature in all the file formats needed.

I have two classes, one nested in the other. [code]Neither "Name" or "ID" are unique between operations and records.I wish to construct a dictionary using LINQ = Dictionary(Of String, Of List(Of Integer), whereby the keys are uniqe examples of Names in my collection and the values are the collective set of distinct IDs that are associated with those names.
View 2 RepliesHow can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
Here is some example code of what I mean:
