What everyone uses for naming conventions?

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.

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 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 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.

I'm working on two different projects - both in VB.NET/Visual Studio 2008 (as much as I'd like to move to 2010).
I find I'm confusing the different coding standards that I'm supposed to follow. IE - Project1 wants variables named in a Hungarian-style notation like 'iSomeValue'; the does not want a prefix. One project requires an _ prefix on private class-level variables - etc...etc...
Are there any tools I can integrate with VS 2008 that will let me easily swap between pre-defined styles and format my code for me?

In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.

How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.

I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version. If he chooses the premium version, then I want it to say premium in his "receipt" later on and if he chooses standard, then standard in the receipt.

I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.

I have created a hotel booking system programme. However, I am puzzled as to how when the booking button is clicked it can search a database and find the best suited room (RoomType) and make sure that it is available (Date of Departure < system.date). It must also assign the value of the cost that is placed in the combobox as the room.roomprice value.

I have been given a task to:Develop a program where a child will be presented with picture of a fruit (one of five possible fruit) on the screen at the click of a start button. The child will then try to recognise the fruit and write its name in a specified place on the screen. On the click of a check button the name of the fruit written by the child will be checked by your program and if correct will reward the child with a suitable message. If the name presented by the child is not correct, a suitable message should be presented on a red background with the correct name of the fruit included in the message.
so far I have managed to create a form with 5 different fruit pictures and a text box below them. a button at the bottom of the form then checks the results and presents a message box to tell them if they have passed or failed.
