Let's say I paste this text in textbox1
"firstname" : john, "lastname" : smith, "country" : usa, "firstname" : billy, "lastname" : brown, "country" : canada, "firstname" : richard, "lastname" : wong, "country" : usa
How could I split up each "firstname, lastname, and country" up? And like add them to 3 listboxes?
I'm pretty much self taught visual basic, using a lot of forums and all, andwas wondering if this is possible. I normally google too but i really have no idea what query I would search (the term). Atm, I'm having troubles making a find replace replaceall thing, so I really can't see myself making something like find '"firstname" : ' and get the text after that till the coma.

I'm having trouble parsing some text. Here's an example of the text:
201 BBQ 0.000 9.000 0.099 0.891 9.000 0.000 0.000 0.000
705 W 1 PC 0.000 135.000 0.295 39.825 0.000 0.000 135.000 0.000
2106 ONL 9.99 41.141 3.000 4.110 12.330 3.000 0.000 0.000 29.970
Here's the latest incarnation of the code I've been trying:
objInfo = System.Text.RegularExpressions.Regex.Split(
newLine,"(d{3,5})|([0-9]+[.]+[0-9]+)|(w*)")
I'm having trouble because I'm avoiding getting many blank spaces in the array after splitting. I'm trying to avoid using the optional | character but I get no results when I set it up without it!
I've spent much of the evening reviewing regular expressions and I've downloaded the following programs:
RegEx Designer.NET
Antix RegEx Tester
Expresso
I'm having trouble because the description contains a decimal point SOMETIMES and sometimes it doesn't. The description sometimes contains a whole number sometimes it doesn't.My friend recommended I use awk to divide it into columns. The thing is...I teach a Community Education class with Visual Basic .Net and I need to improve my RegEx skills.

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

want to know if anyone knows how to seperate sentences in a dialog box? what I mean is this.I have a rather long warning attached to my closing dialog box that really needs to be there. The problem is that it appears all in one long string and I would like it to in a seperate string.Are you sure you want to exit without saving changes? If you close this window, you will close the program and lose all unsaved data!this is all coming out in one long sentence..what I would like it to look like is this:Are you sure you want to exit without saving changes?If you exit this Window the program will close any unsaved data will be lost!

I'm trying to wrap my head around creating dll, and since I've been using a variation of the code below, i was wondering if someone could comment on if it would be possible to separate the code from the form and create a dll with it, I've been using this in my application successfully and since I'm familiar with it, I thought it would be a good project to learn on.
This is the code for the form docViewerForm.vb

What I am trying to figure out is a simple dice rolling program (I'm assuming it's simple anyway) that lets the user specify how many dice they want to roll and then after they click the roll button it separates the dice by what was rolled so they can see how many 1's was rolled, or how many 2's were rolled, so on and so forth for 6 sided dice.
Say the user wants to roll 6 dice, when the user clicks the roll button the results are 4,3,3,5,1,6. Obviously meaning they rolled two 4's two 3's one 5 and one 6. Now from that result I want to have separate labels that show how many of each number was rolled, so it would look something like this on the form (Except it would be horizontal instead of vertical, but it doesn't work on the forums)
1's: 1
2's: 0
3's: 2
4's: 1
5's: 1
6's: 1
That's just a basic example, of course if the user added more dice there would possibly be up to say 7 4's and 10 5's or whatever. There isn't really a limit to the results you can get.Now I found some code to do let the user specify how many dice to roll and have it roll that amount of dice, but I don't know how to separate the results like I want them above. Right now it just displays the results all in one line on a label.Here is the code that I am using
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim diceCount As Integer = TextBox1.Text
If diceCount = 0 Then MessageBox.Show("Please insert number of dice needed")[code]....
It works perfectly but how would I go about separating the results like how I was explaining? I'm sorta guessing I would use case statements or something of the sort but I'm not sure how to check the results of dices to be able to separate it.

I have a solution in VS 2010: a WCF Service Library project ("NotifyService") and two Windows Forms projects, one for a server ("NotifyServer")and one for a client ("NotifyClient"). My goal is to have a duplex WCF service that will notify any number of connected clients when the server pushes out a notification. The clients do not need to communicate to the server except to subscribe and unsubscribe from the server's updates. However I seem to be running into problems nailing down the InstanceContext.
Here's the code for the WCF service:
<ServiceContract(
CallbackContract:=GetType(INotifyCallback),
SessionMode:=SessionMode.Required)>
[Code].....
Since I'm setting everything up through code, there are no app.config files. The problem I'm having is that my Subscribe method is never called. When debugging, I get an error after stepping through that line (not an exception) that says "Unable to automatically step into the server. The debugger failed to stop in the server process." When I go back to my server form and click the button designed to raise an event on the callback clients, it steps into the NotifyService class but the _callbacks list is empty, meaning the Subscribe method either never ran, or it never ran on that instance.
I have fought with this for almost a week. This is nearly an identical copy, at least on the service-side, to what was described here, and I've compiled that and it works.

I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

I long variable in vb.net which contains the following information,
Dim g As String = "$C:Program FilesCavaj Java Decompilercavaj.exe$C:UsersYoosufAppDataLocalGoogleChromeApplicationchrome.exe$C:Program FilesDVD Makerdvdmaker.exe$C:Program FilesAdobeAdobe Photoshop CS2ImageReady.exe$C:Program FilesJavajre6injavaws.exe$"
The $ symbol is used as a delimiter to separate each item from the other. I need to add the exe file name at the end of each path to a listbox. However the initial process of retrieving the variable to individual array elements is not working properly.
Dim strArr() As String = g.Split("$") 'This variable is empty
For count = 0 To strArr.Length - 1
Dim arr As String = strArr(count).Split("")

Im working on this webbrowser and i have fully integrated a working Proxy (it will use a proxy such as 100.00.00:0000)It will only change the proxy ip if you do the code:RefreshIESettings("100.00.00:0000")(That is a code i made, declared i mean)Anyway so heres what i wanna do:I want to have a richtextbox or something, with lines of proxy ips, such as this:
100.00.01:0000
100.00.02:0002
100.00.03:0003
[code]....
So i thought maybe if you convert that richtextbox text into a string, it might be easier?

I'm working on a project. Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.

Currently I am using .NET to break apart multi-page tiffs into separate jpeg/pngs. The process on its own is perfectly fine. But after few weeks, I notice one big flaw in the page sizes. Each page I separate is the same (width/height NOT FILE SIZE) as the whole TIFF document combined. When the TIFF is displayed,this creates a massive black spot on the right/bottom of the image. This is a very big flaw as I can't determine the physical dimensions of each page as I am separating them. If I know ahead of time, I can at least write up some kind of cropping mechanism.
