Naming Conventions - Name Member Variables In .NET?
Jun 9, 2010I 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.
Naming For Namespace / Class And Variables
Jul 7, 2009In 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

Naming Convention For Variables In Class Constructor
Nov 26, 2010In 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?

View 1 RepliesSlow IDE - Faster Way Of Naming Controls?
Sep 21, 2010I 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?
VS 2008 Change Default Naming Of New Controls
Nov 24, 2011I was just wondering is there a way to change the default name when you add a new control? I like to name my controls btnSomething etc... and if i could change the default names of added buttons from Button1, Button2 etc to btn1, btn2 etc.It will save me time when renaming.(Same applies for toolstripmenuitem buttons)Actually what would be ideal is if when i add a button, i directly go to the input for Text, and when i change that for the first time (like with toolstripmenuitems) the name changes according to the text (e.g. when you add a toolstripmenuitem in a context menu strip, if you set the text to "Reset" the name becomes ResetToolStripMenuItem. It would be awesome if i could make it automatically name to btnReset for buttons and tsmReset for toolstripmenuitems.)If there is a way to do this, even a difficult and not exactly pretty one involving macros and an input box, i would like to know

Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared
Aug 24, 2009I 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 RepliesNumericUpDown Controls - Update Some Variables Each Time One Of These NumUD Controls Changes Value
Nov 20, 2011I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.

Inherit Form - Events From AaMyForm Execute Correctly But Controls Added To It Are Not Shown On XForm
Oct 31, 2011Public Class aaMyForm
Inherits Windows.Forms.Form
Added some controls. Build it, add the .DLL as reference to my other project.
In my other project:
Imports MyLib

The events from aaMyForm execute correctly but the controls added to it are not shown on XForm. I have found some info about set Modifiers Protected in order to be able to change the functionality of the controls but havent found anything about why the controls aren display on the XForm.
Using Variables In Controls?
Aug 31, 2009I am trying to program a Yahtzee game. I would like to use a random number (out of a six sided die) and show the appropriate dice image based on the number generated. I have six predefined pictureboxes that each have a side of the dice image. I want to mimic the picturebox based on the number received.
For example:
x = Int(1+Rnd()*6)
die1.Image = diex.Image
Where x would be the random number and would pull from the appropriate picturebox.
Enumerating Controls With Variables?
Jun 22, 2010If I had 5 text boxes on a form, TextBox1...TextBox5, is there a method to do something like this?
Dim strFld As String
For intFor = 1 to 5
strFld = "TextBox" & intFor
Me(strFld).Text = intFor
Next
It doesn't like the line of Me(strFld) but I figure there must be a way to reference a field via a variable instead of hardcoding the field name.

View 1 RepliesIDE :: Re-naming/re-using A Windows Service?
Oct 18, 2011I'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.

Mar 1, 2011I wish to be able to instantiate my Cell class while naming the cell instance with such name as "A", "B", "C", etc. just like in an Excel spreadsheet.
I have my Cell class like so:
public class Cell {
public Cell(Range nativeCell) {
NativeCell = nativeCell;
[Code].....
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?

Jan 7, 2011I'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.
