I have a class (let's call it foo) that has several public properties.
private _fee as object
private _fie as object
private _fo as object

So far this seems to work... I'm just worried that something might get screwed up scope wise.
What is the normal way someone would name the constructor variables in a class like this?
In the past when I have written classes and constructors, I named the variables in the constructor parameter something different than what would have been stored in the actual class itself.What I do now is name them the same, and reference the internal variables with Me.varname.Here is a class I just started building.Is my naming convention incorrect? [code]
View 1 RepliesWhat is the most commonly used convention (in C# and VB) to name object, when I want to emphesize that it is an instance of class that implements some interface. Like here:
//is iDisp correct name?
protected void Dispose(IDisposable iDisp)
{
iDisp.Dispose();
Console.WriteLine("Disposed");
}

View 4 RepliesI am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.
View 4 RepliesI am trying to create a number of objects depending on the width of a row of an array, is there a way I can change the name of the variable being Dim 'd as I don't know how wide the array will be.
I have been trying something along the lines of:

For x as integer = 0 to UBound(MyArray,2)
Dim Object & CStr(x) As Object Type

In the example below, what would you name the parameter given that it is used to initialize the property FromDate?For class constructor methods, I like to have the name of the constructor parameter variable match the name of the property which is being initialized. For example, the parameter "fromDate" is used to initialize the module level variable "_FromDate" with the statement _FromDate = fromDate. Likewise, I could have alternatively written Me.FromDate = fromDate.
Proponents of C#'s case sensitivity would probably say that using a leading lower cased letter for the param variable name, which I believe is MS convention, is an acceptable approach to distinguish it from the Property of the same name but different casing.
However, VB is not case sensitive, which I generally appreciate. In the following example, I am using a param name that matches the property name, 'fromDate," and VB refers to the local instance when there is ambiguity. However, many would probably argue that this "ambiguity" introduces the opportunity for the developer to get confused and not realize which variable is being used. For example, my intent below was to have TWO params passed in, "fromDate" and "toDate" but I accidentily ommited one and as a result, the VB.NET did not warn me of the mistake because it assumed that the statement _ToDate = ToDate was equivalent to _ToDate = Me.ToDate instead of informing me that the variable on the right side of the assignment statement was undeclared.
Public Class Period
Property FromDate As Date
Property ToDate As Date
[code]....
In my judgement, we should have a convention for prefixing all parameter variable with a prefix, but hasn't the use of prefixes been discouraged by Microsoft? For example:
Public Sub New(ByVal paramFromDate As Date, paramToDate As Date)
..or maybe it could be shortened to pFromDate, pToDate...
I don't know if this has been asked before, but we're having a discussion about it today at my job. Should private variables (that are shared/static) be instantiated when they are dimensioned/defined, or is it a better practice to do this inside of a constructor?
Public Class IpCam
Private Const HOST As String = "http://test.com/url/example"
Private Shared _Example As New OurClass(HOST)which one to use?

I've been trying implement Constructor method in passing variable between two forms.Just a rough user interface guide - issue Invoice. User would type in all the Customer Name, Document Number. Once he reached Item Details, a Child Form would pop-up for the User to select/search the Invoice's Item; Once selected, the selected item would showed in the primary Form.
What I had tried is, the Constructor method worked perfectly when it is self-contain in a new project, yet to be implement in my application.But when I implemented, there is an error: Reference to a non-shared member requires an object reference.

I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.
Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod
[code]....
I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me
example:
Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

View 12 RepliesSo, I'm trying to do things according to accepted convention as much as possible.
I have a DataTable that holds data that is read in from an XML at the launch of the program. This DT contains data about folders that are added by the user. It is primarily accessed by a single form, but another form used for Adding/Editing folder data will need to update it.
So, what is the best way to handle this: Currently the DT is created/maintained in the main form (FolderPad) that uses it. Would it be better to put the DT in a public Module for access, or allow the add/edit form to access the reference to it in FolderPad? Or is there a more accepted way to do something like this?
the question is really what is the correct convention (style) for raising and handling events. When a button is clicked it is generally handled by this method. [Code]
I have recently been trying to follow this convention by creating my own EventArgs class and inheriting the system.eventargs, Then adding my own properties. The problem is as my projects get bigger/complex I seem to be writing multiple eventarg classes. I then decide to try and create a generic eventarg class but this then seemed pointless thinking it would be easier just to pass the object directly instead of wrapping it up in "someEventArg" i have created.
What everyone uses for naming conventions?

View 1 RepliesI've created a VB.NET2010 stub service application with a bunch of common features that I'd like to be able to use repeatedly as the starting point for various more specialized projects.
For each spin-off project I want to be able to start with the stub and then rename the service "completely", so that each instance behaves as if it was created from scratch with its own unique name.
I've tried the steps below with limited success; the re-named service builds as wanted/needed, BUT it won't run because I can't add the new service name to the StartupObject pulldown list.
Change ServiceInstaller.ServiceName from stubName to newSvceName.

I would need to generate a name based on the alphabetic letters and double and triple them once I encounter the last alphabet letter 'Z'. The algorithm would have to generate the letters that I would concatenate with the rowIndex value that would result to this naming strategy such as Excel.
The letters would be:
A, B, C, D...Z, AA, AB, AC...AZ, BA, BB, BC...BZ, CA...XAA, XAB, XAC...
While we clearly know that colIndex value 1 will definitely designate column "A", value 2 = "B", value 3 = "C", etc.
My problem is particularly when we double the letters.
how I could achieve this in the simplest possible form?
Can some one please be kind enough to link me m$ naming guide lines.
View 2 RepliesI am generally not one to engage in subjective arguments over matters like variable naming, code formatting, etc. So I have no intention of starting an argument here.I just came across this (old) blog post which recommends not prefixing member variable names:
[Code]...
I get it: member variables can be lower camelCase, and public properties/methods can be PascalCase. But VB.NET is case-insensitive, so you can't really give a private member the same name as a public property except with a lower case first letter.I've generally prefixed member variables with an underscore, but I've been told that's not idiomatic.
So really I'm just curious: how do you name your member variables in VB.NET? And is there a "standard" way?
I'm not asking because I believe there's a "right" way or because I particularly want to change my style, and certainly not because I have any desire to tell others they're "wrong." Like I said, I'm just curious.
In the code below, the namespace is called "Navigation" which I think is correct. Then I have a class called "Heading", which by definition is the direction a person/vehicle is truly pointing towards. I think that is also named correctly. In the code below, I have four things I have named:
_WhatToName1, WhatToName2, WhatToName3, and WhatToName4.
The value that gets passed in and stored is a double between 0 and 360 -- essentially the degree value from a circle. For WhatToName3 and WhatToName4, I have seen a lot of places that just use "value" as the name. Is that standard?
Namespace Navigation
Public Class Heading
Private _WhatToName1 As Double
Public Sub New(ByVal WhatToName3 As Double)
Me.WhatToName2 = WhatToName3

I have experienced this in both VB 2005 and 2008. First, design a form by placing your UI elements where you want them. Then, go back and start naming your controls the way you want them (i.e. "txtWhatever" instead of the default "TextBox1", etc.).I find that after you change the name of a control, there is a slight but annoying delay as VS IDE digests the fact that you changed the name, thus slowing down my workflow. I recall that this process was much more rapid-fire in the VB6 days - i.e. name one control, click the next one and start typing, boom-boom-boom.
Has this annoyed anyone else, and if so, have you found any kind of remedy to speed things up in this regard?
Are there any naming standards for constants that are different than variables? ex: Const for the prefix of the name.
View 3 RepliesI'm creating an application that allows the user to create their own queries based on criteria in various list boxes and my idea was to produce the results of the SQL in a "new" DGV, which in turn will be created in a "new" TabPage in a separate form . Each time the user runs a query a new DGV and TabPage is created. I've named each "new" DGV based on a user textbox so each "new" DGV will be named differently. The problem is how do I reference each new DGV? At the moment I get-"the value of type 'Syst.cannot be converted to string"It allows me to name the DGV with a string, but not reference it!
Any ideas how I reference a DGV when its created in runtime.
