View 12 RepliesDifference Between A Private, Public, Shared Functions/Sub/Variables?
Jul 22, 2009give 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.

Dim iString As String

MsgBox("You alredy have the maximum amount of IP Addresses stored, delete one to add another.", MsgBoxStyle.Information, "Program Error")

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 .

Inheritance (Private Overrides Function) - Create A Class And All Other Classes Inherit From It And Modify It A Bit
Oct 15, 2011I am cleaning up some code and I have multiple classes that are 99% exactly the same. So my understanding is that my options are...
1. Create a class and all other classes inherit from it and modify it a bit
2. Create an abstract class and all classes inherit from it and modify a bit ** I took this route
3. Create an interface and all classes Implement that interface.
Here is my 'original' class below (the one that all of them look 99% identical). This class is used in an arraylist so I have a listing of all my images from a folder I have searched.

View 1 RepliesPrivate Declare Function BlockInput Lib "user32" (ByVal FBlock As Long) As Long?
Dec 26, 2009In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy

Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
When To Use Dim Vs Private
Nov 17, 2009I am pretty new to VB.Net and OOP in general and am picking stuff up every day, but it is so easy to become burnt out with the sheer amount of info. Therefore I am taking it slowly. Yesterday I was reading my book and read that using Dim for class level variables is allowed(if the compiler is set so) but is bad design and I should instead use Private. Dim defaults to private anyway. So my question is where should I use Dim instead of Private?

View 6 RepliesModule Private To Everything But One?
Aug 22, 2010I have a "Main" module that is sort of the "brain" or "top level" of my project. Basically, I think there are routines that it only should be allowed to call. Some of these routines are in other modules, so I don't know how to make them hidden to everything except the Main module. If the routine is ublic, anything can call it; if it is private then the Main module can't see it. Also the other modules are big enough that I don't feel it would be a good idea to stuff them completely inside my main module. How can I achieve this "private except in one place" functionality?

RSA Private Key Encryption?
Aug 10, 2009I'm looking to use RSA Asymmetric encryption to encrypt some data. I've read this article on the forums with a similar title, but it did not answer my question. What I would like to do is use the private key of an RSA key combination to encrypt (sign?) the data and use the public key to decrypt (verify?), as per this wikipedia article . I would like to use this method because I want people to be able to read the data, but not create it themselves. I've copied the code from Peter Bromberg's article RSA Encryption in .NET Demystified , but always get an exception with the "Bad Key" message. If I use the public key for decryption, it works fine (the opposite of what I want). use the public key for encryption.
