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")

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 .

IDE :: Set Project Default For Winforms Projects S/ Default Modifier For Controls Added To Winforms Is Private
May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
View 1 RepliesInheritance (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.

Private 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
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
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:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

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.

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
