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

In main form I am displaying dynamic link lables something like below..
Living Certificate - 30
On click of this link I am invoking another form and some process is being done. On saving the count 30 will be reduced by one. Like this many link lables with diffrent headings will be there. Now problem is when I finishe the process and come back to the parent form, the refresh is not happening, thou I am refreshing it. I need to log out and log in to get the correct number again.

Ho can you make a dynamic label stay right justified, so that when the label.text is filled the text starts at the right edge of the label and fills to the left? Currently the text fills to the right from the left edge of the labels location and tends to run off the form.

I have a picture box with a label underneath it. The text of that label changes based on events. The problem I have, is when the text changes the label is no longer centered underneath my picture box.

I'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 am creating the pictureboxes through code in VB, and I am trying to give them instance names through code, since they do not exist in the forms physically (I cannot manually name each one), only when I run my application (using VB 2008 express). The pictures work, they are displayed when I run the application but I need to find a way to be able to call each one because I need to create motion animation for every separate picture object.

Mostly because of reading this site, I'm trying to move away from Hungarian Notation. Or I guess the improper (system) Hungarian.
I can figure out a better way to name most data types, but I don't know what to do with objects. What would be a good naming convention for objects? I use objRS for recordsets now.

I 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?

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
[Code]....
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?

I 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
[Code] .....

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?

I'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.

I'm relatively new to .NET and am wondering how people handle naming their private variables and the public properties that access them. Like if you want to be able to just read it, but not write to it.
[Code]...
So far I've taken to putting a 'l' (for local) in front of the all the private variables so as to be able to use the full name for the property. Is there a better way around this, or do you just always have to have different names for private variable/public properties? If so, what sort of conventions do people use?
Its not a huge deal, its just a minor annoyance and I was wondering if I was missing something.

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?
