My group is attempting to standardize on XML commenting for all of our classes and methods. We like the "Insert comments" option in VS 2005 but would like to add an additional tag <history> to the comments section. I know that we could probably do this manually each time we add a new class, but I would like to be able to have this new section come up automatically when we insert the comment.

I used reflection to get the classes, methods inside an Net assembly. Everything works fine when a function only have one version (not overloaded), but when i get overloaded versions i can't get any version...
I build a simple application with a simple class and added a method with two versions, and i can get the correct version using the GetMethod.I don't know if it's the parameters type, but i can get it work. Example, the sub BASS_Init has 2 versions
BASS_Init(ByVal device As Integer, ByVal freq As Integer, ByVal flags As Un4seen.Bass.BASSInit, ByVal win As System.IntPtr, ByVal clsid As System.Guid)and
BASS_Init(ByVal device As Integer, ByVal freq As Integer, ByVal flags As Un4seen.Bass.BASSInit, ByVal win As System.IntPtr) And one of the next two should work, but none works get nothing every time:

We build a class (i.e. Server) and create a LOAD method that loads a dataset with all the details of that object.We need all that information sometimes... but what about when we only need one piece of data from that object (i.e. webserviceUrl).Should we build classes with a bunch of scalar methods that get back single pieces of data as opposed to only getting ALL the data and then only taking what we need?It's a waste to get all the data when we dont always need all of it but it also will take longer to write the extra methods..
View 2 RepliesI will preface this by saying Im previously an asp developer and am learning oop programming/Vb.Net
Im working on a 3 tier architecture and trying to abstract my code as much as possible since I have a very large intranet to convert. In my business layer I am defining my classes with management methods. Below is an example of one of my classes.
My question: Is there a way for me to genericaly refer to the class type and object type so that I dont have to continualy refer to the class name/type "ServiceRequest" throughout the class. For example something like:

I have upgraded a visual basic 2005 project to visual basic 2010 (.net framework 4.0). I want to list all obsolete functions used in this project in order to change it with newer ones. How can I treat obsolete functions warnings as errors in visual basic 2010 ms-build?
View 1 RepliesI am working on a VB.Net application that needs to access a web service that I am nearly certain has a C# backend. At bare minimum, the backend is providing classes to me that are differentiated only by case, and within a number of those classes, there are properties and methods that are only differentiated by case.
VB.Net is case insensitive, and it sees a number of these items as being ambiguous.I've thought of a few ways of dealing with this, but I would like suggestions before I go down a road that is likely difficult.
Here are some ways I have considered going about it.Modifying the generated code for the wsdl. This has presented problems in responding as the xml output would no longer conform to the webservice requirements.I think there might be some attributes I could use to override this, but I'm not sure what they are yet. Even so, this web service gets frequent updates and I would hate to have to keep refixing the service every time I refreshed it.Creating a csharp wrapper project where I expose the underlying classes with different names. Primarily through inheritance. Although the big problem here has been the issue with properties and methods that are only differentiated by case as well.
I'm sure at some point I could get one or the other of these solutions working, but if anyone has any better suggestions that I'm not thinking of,
I want to know what are classes , objects , a namespace , subroutines,functions,methods,properties and differemce betweem byval and byref in your words.
View 18 RepliesAccording to conventional programming, how is it to properly comment using the '''<summary> feature built into Visual Basic?Would I have to use the part that says
''' <param name="text">Description here

Here is the full commenting process; is it necessary to use all of it?

This might be a really easy one but I couldn't seem to find an answer anywhere I'm trying to comment my code as follows
Session("test") = "JAMIE" _
'TEST INFO
& "TEST" _
'ADDRESS INFO
& "ADDRESS = TEST"
With the code above i'm getting the error Syntax error But when I remove the comments like so
Session("test") = "JAMIE" _
& "TEST" _
& "ADDRESS = TEST"
It works fine so my guess is that I cannot comment my code between the _ character.

View 3 RepliesI am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?
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.

I'm kind of confuse on how to use get and set in vb how would i access the get/set method within the class and when i instantiate the class somewhere else? in java i would make a 2 methods call like get_item set_item and i can just use the the method name i made. to retrieve or set within the class/object or when i instantiate it somewhere else. but in vb there is a property method and 2 methods inside(set,get)?

I have two methods on the page. One AddMessageToInboxOutbox(params[]) and other one SendNewMessageMail(params[]).
Once user sends an message to other other first message is added to DB and then sent to recipient's email. Sometimes SMTP is heavy loaded and it takes up to 5 seconds to get answer from it. I want to enclose SendNewMessageMail(params[]) with async call using other thread or something. I have never done that.

I've seen extended .NET method libraries such as this and this.In VB.NET, since you create your extended methods in a Module, How do I make them into a DLL?? (like in those links above) Its not possible to build and get the DLL from a Module.
View 7 RepliesI created a couple of extended methods in a VB.NET module. I put them inside a Class, built it and got the DLL. From another program I made a reference to that DLL and imported it using Imports as well.The extended methods appear in IntelliSense and it works but a warning appears in the Error console saying,Could not resolve this reference. Could not locate the assembly "nK0deExtendedMethods". Check to make sure the assembly exists on disk. why this error occurs even though I have referenced the DLL?
This is the Class where I've put my module with the extended method.
Imports System.Runtime.CompilerServices
Imports System.Drawing

In VB.NET when i define a subroutine (or function) , while declaring arguments , a list comes out. Having values ByVal,ByRef,Of,Optional, and ParamArray. Of these five lists , four are better understood except "Of". I searched and found that "Of" is used for Generics .Generic Class or Generic Method.
But i did'nt find any procedure that how to create and use Generic Method in VB.NET. I found same in VB.C# language.
