give me a good resource that explains the difference between a Private, Public, Shared Functions/Sub/Variables? I normally use Public for Subs/Functions inside of Modules I call from other parts of the program. But I'd like to get more of an understanding of how and when to use them. I want as little as impact to a system that is running my programs as possible, so i guess the key here is I'm trying to just get more proficient in my coding.

I have a class like this:
[Code]...
It works, when I make getBar methods public, but I don't want to expose these unneccessarily. Why I can't call private shared methods from a public one in the same class is over my head. I'm using .net framework 4.0 in a web application.

i want to add calculations in 1 private function I have a textbox named lbldisplay.text when i enter a number.. the number is shown as a string so.. -private number1 as string when i press the button "+", "*", "-", or "/" the number1 must return into a double. So the number in the textbox is now a double.. so for example i press the + button, and i need to fill in a new number.. but this new number is also a string!

I am using visual basic and trying to create function. I am getting this error:
"Argument not specified for parameter '_IsDayRateCheckBox' of private function CalculateParikingCharges(_HoursDecimal As Decimal, _IsDayRateCheckBox As System.Windows.Forms.CheckBox) As Decimal'.
This is the code.
Private Function CalculateParkingCharges(ByVal _HoursDecimal As Decimal, ByVal _IsDayRateCheckBox As CheckBox) As Decimal
This is how I call the function.
Dim HoursDecimal As Decimal
Dim AmountOwedDecimal As Decimal
If Not Decimal.TryParse(HoursTextBox.Text, HoursDecimal) OrElse HoursDecimal < 0D Then
ErrorLabel.Visible = True
HoursTextBox.Focus()

i made this code
VB.NET
Dim iString As String
If My.Settings.IPBank.Count = 30 Then
MsgBox("You alredy have the maximum amount of IP Addresses stored, delete one to add another.", MsgBoxStyle.Information, "Program Error")
[Code]...
I want it to check all of the items in the my.settings.ipbank which is a stringcollection. Before it adds and if it already exists in my.settings.ipbank then i want it not to add it. But it just adds when i run it. And then once its added it says: "Collection was modified; enumeration operation may not execute." But also before i run it. There is a warning saying: Function 'AddTo_IPBank' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used. Is this something to do with it? I think i have the Next in the wrong place .

How can I create a function from this example:
Private Function CheckForNull(fieldvalue as string) as Boolean
That checks that all my fields are not empty? For example, say I have three fields txtFirstName, txtLastName, and txtAddress. How would I write the function above that would check that these fields were not left empty?

I'm new to C#.Till this moment I used to make every global variable - public static.All my methods are public static so I can access them from other classes. I read on SO that the less public static methods I have,the better.So I rewrote my applications by putting all the code in one class - the form class.Now all my methods are private and there's no static method.
My question: What should I do,keeping everything in the form class is dump in my opinion. When should I use public,when private and when static private/public? I get the public methods as a 'cons' ,because they can be decompiled,but I doubt that.My public methods can be decompiled too.What is so 'private' in a private method? EDIT: I'm not asking how to prevent my program to be decompiled,I'm asking whether I should use static,private and public.And also : Is there are problem in putting all the code in the form class so I dont have to use public methods?

is there a way to have the Get part of a property available as public, but keep the set as private?Otherwise I am thinking I need two properties or a property and a method, just figured this would be cleaner.
