Add Description To Functions And Function Parameters?
Apr 19, 2011
I'm writing a VB.NET function with a ton of overloads. I've seen that most .NET functions have parameter descriptions in IntelliSense. For example, when typing in String.Compare(, IntelliSense says Compares two specified System.String objects and returns... you get the idea. This description changes and you click through different overloaded versions of the same functions. When you start typing in something for a parameter, it describes the parameter you're currently inputting as well. Example: strA: The first string to compare..

How is it possible to add a function description in VB.NET (VS 2005)? in C# this task is resumed to tape 3 times the "/" simbol just above the function declaration. (generates the <summary> tag and others)

Well I am a new to VB.NET, converting a legacy system to .NET world. Recently I have been reviewing the already existing code since I joined the project quite late in the team. I find that there are many shared functions (not shared class) inside many classes. I doubt this may create some problem if two requests ( i.e two different HTTP request to the same method as it's a WCF application, of course exposed methods are not shared but internally called methods are shared) comes to the same shared method and both the calls to the method may have different method parameters/arguments, overwriting each other's arguments. In short, if shared method has a list of arguments which is going to be processed, is there any chance of inconsistencies in the light of multiple access to the shared method via two http requests.

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.

I get the error at the end of the line, after the close par...the error is "optional parameters must specify a default value".

The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).

Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object.

I get this error: Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
Partial Class _Default
Inherits System.Web.UI.Page
<WebMethod()> _
[Code]....
I know it has something to do with the fact that the first function is shared and the second function should probably be Public as well but I don't fully understand the reason behind it. Probably not relevant but I'm calling the web method from some javascript.

I am currently working on a project witch contains lots of functions and properties. These functions and properties are stored in the dll. If I reference to this from within my project, these functions and properties are all in the same namespace or class. (I don;t know how it is called)Example:If I type the root namespace: Functions. I get all the functions. I would like to organize them in:
Functions.Maths (All the functions involving maths)
Functions.Internet (All the functions involving the internet)
Functions.Language (All the functions involving languages)
I tried using classes but I cant access the properties when they are stored in a class. I don't know why.

where the VS debugger refuses to show certain field types including dates.My call stack contains FunctionA which calls FunctionB. FunctionB has about 45 parameters and many of them are dates.When I step into functionA,
1. the debugger refuses to show a date variable when you hold the mouse over it. It just shows {Date} instead of a value
2. If you do quick watch on that same variable, it also just shows {Date} instead of a value
3. If I do ?variablename in the immediate window, I get "System Error &H80131c23&"
When I comment out the call to functionB, the date variables all show correctly in all the above methods. I will stress that the code has not yet reached functionB, just its very existence in code screws up the debugger.I'm thinking this is a memory issue and maybe vs debugger can't cope with a huge function stack frame dataspace.devenv is only using 268Meg of ram on a 2Meg box, with not much else running. Thats reasonable for this size of project.

I am trying to clean up my code a bit.
I made the following function:
Public Sub sqlUpdate(ByVal table As String, ByVal column As String, ByVal var1 As String, ByVal column1 As String, ByVal var2 As String)
Public CN As New MySqlConnection
Public cmd As New MySqlCommand
[CODE]...
Which is fine, if I want to use mysql update all I have to do is call something like: sqlUpdate("test", "test", 0, "test", test) I was wondering if I could do the same with the SELECT statement and make a function. I cant think of a way to do it though...
sqlConnect()
Dim cmd As New MySqlCommand
With cmd
.CommandText = "SELECT * FROM users WHERE username=""" & lblAccountName.Text & """"
[CODE]...
The data I would want to extract would be different every time.
