VS 2008 Private Function With A Loop?

Aug 20, 2009

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 .

[2008] Call Parent Function From DLL

Jan 12, 2011

I have a bunch of VB.NET programs that have a general purpose logging function to log events, errors, exceptions, etc. It looks like this:

Sub LogMe(Msg as string)
LstLog.items.add(now.tostring & " " & Msg)
End Sub

I wrote a few VB.NET DLLs that contain classes used my my VB.NET programs. In thoses DLL classes, I would like to also trap some events, errors, exceptions, etc. But I want them to be logged using my main LogMe function. Here is some pseudo-code of what I was looking for:

' Main program code
imports MyLib
' Initialize program

[Code]...

I assume I will need to define Delegates to save my LogMe fonction pointer

[2008] Make Sure That Each Call To The Function Is Much More Random?

Jan 15, 2009

I have a function called DieRoll. In the function I have the following setup.

Dim objRandom as New Random
Dim intRoll as Integer
intRoll = objRandom.Next(1,7)
Return intRoll

Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

Apr 1, 2010

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.

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

Here's my call:

<script type="text/javascript">

function HelloWorld()
{

var yourName = $get('txtYourName').value;

I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use

Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector).

Function Call For Multiple Textboxes Using Visual Basic Studio 2008

Feb 17, 2010

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.

If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....

Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished

Jan 25, 2010

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).

Anyway what I am trying to do in steps:

1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.

The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.

I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?

Sep 14, 2010

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()

takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:

Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)

Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?
