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.
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 am currently trying to separate my text into groups of 5.For example.Original text is ABCDEFGHIJKI am trying to make the output to something like this ABCDE FGHIJ K
I have a database table that stores a datetime value.I want to display that value on my asp.net textboxes, except I need to show date value in TextBox A and Time in TextBox B.How can I split those values in VB.NET?
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 got a text file where each line is build like this:
00:00 - string time - a string simple right?
but now i want to seperate them so a timer checks the klock and load each line when the time is correct. i�ve got this
Dim objReader As New System.IO.StreamReader(FILE_NAME) Dim s As String For Each s In objReader.ReadToEnd
[Code]....
i know that the file extist. but the problem is i get error saying "length cant be less the 0" in the "dim s1 = s.substring(0,i) ( the code is in timer_tick)
im trying to get a name entry from an input box to show up in two separate places on my project, ie first and last name, but i either get nothing or the same text for both labels.[code]
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.
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 want to separate each text into their own Column in VB.net.How do I achieve this?
Each entree is seperated with "|" . My Code:
Private Sub MenuItem3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem3.Click Dim folder As String = Environment.GetFolderPath(Environment. SpecialFolder.Personal)Using sw As StreamWriter = File.AppendText("My Expenses.txt")[code].....

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?
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.
System.IO.Stream s = new System.IO.MemoryStream(imageData); System.Drawing.Image i =[code]......
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!

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
I have a program that tracks packages. Shipment and package entities are persisted in SQL database, and are displayed in a WPF view. Upon initial retrieval of the records, there is a noticeable pause before displaying the new shipments view, and I have not even implemented the code that counts shipments that are overdue/active yet (which will necessitate a tracking check via web service, and a lot of time).I have built this with the Ocean framework, and all appears to be doing well, except when I first started my foray into multi-threading. It broke, and it appeared to break something in Ocean... Here is what I did:
Private QueryThread As New System.Threading.Thread(AddressOf GetShipments) Public Sub New() ' Insert code required on object creation below this point.
I realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3 Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.

i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.

I am working on a project for school and I am encountering several errors in my code relating to the numeric up down boxes I have in the application. I have inserted my code and the error list below. I'm sure that it is probably something really simply but I am learning the language on my own and I am a little stumped here.
