.net - Split Function - How Does It Works
Feb 10, 2012I'm trying to get split to work.Here is my code
Public Sub CheckUpdate(ByVal FileURL As String)
Dim instance As WebClient = New WebClient
Dim ApplyTo As String = instance.DownloadString(FileURL)
asd = ApplyTo.Split(",")
End Sub
I use it like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
NewUpdate.CheckUpdate("version.txt")
Label1.Text = NewUpdate.asd(0)
End Sub
(yeah I know i use it on local txt for now!)So with asd(0) it reads the whole file. If i check asd(1) I get IndexOutOfRange . So how does Split() work?
Recursive Function Works On X86 But Not X64?
Mar 12, 2011I'm making a program that can mark my shooting cards and i have created it and it works nicely But i want to get as much speed out of it as possible so I switched my target CPU to X64 and sure enough my recursive function threw a Stack overflow exception telling me i need to make sure i don't have Infinity recursions. Strangely when I set It back to X86 the same recursive function works...

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.
VS 2008 Make A Function That Does What This One Does But Works Faster?
Oct 27, 2009I have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.
Option Strict On
Public Class Form1
Dim sw As Stopwatch
[code]....
The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.
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. 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

View 1 RepliesAuto-generate - Updating Function - Hospital System Which Works With A Access Database ?
Jun 21, 2010I am using vb to make a hospital system which works with a access database. i am having an issue with the updating function to the database, this time round instead of hard codding the connection i used the connection/data source wizard, in microsoft visual studio 2008 and there fore most of the code has been auto generated for me, which includes the insert, delete and update funtions from what i can find and what i have read vb is ment to also auto generate this which it is not. the funny thing is that i can close the program down and reload it (as long as i haven't opened the database) and my changes are still there but if i go and open the database and it hasn't changed. also i can change the database through the use of the Dataset connections in the datasource tab but not int he program the code ive found and believe that is meant to update the database
This is running off a couple of buttons i also have a update query but have know way of accessing it

Make Picturebox1(function Already Assigned) Perform The Same Function As Picturebox2(no Function Assigned)
Aug 1, 2009i wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.

View 1 RepliesSetting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters
Feb 17, 2011I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished
Jan 25, 2010How 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, 2010I 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?

May 24, 2011To have a function that takes the average (which is calculated by a different function) say for example the average is 6, now the function is to take the number 6 and get the variance from six to another number lets say its 12 so this will return a calculation of 50% variance. now here comes the issue, i have it calculating the variance how ever lets say that there is a score that is 0, how can i make it calculate the variance without taking count for that 0? i guess you can say i need it to "skip" if its a 0.
