Ok this is what I'm stuck on:I have 2 ListBoxes and 2 Lists, let's call them ListBox1, ListBox2, List1 and List2.List1 needs to be associated with ListBox 1, and List2 with ListBox2 I loop through a bunch of accounts, add them to LixBox1 at run-time.During that loop I add each account number to List1 so now the account number is associated with the ListBox index number which is right.Now when I double click one of the accounts in ListBox1 it is added to ListBox2 (but it still remains in ListBox1), and the same index of List1 added to List 2, now the account in ListBox2 is associated with the account number at the same index in List2 you see where I'm going with this?The issue wtarts here.When I double click an account (let's say the account at the first index) in ListBox2 it should be removed from the list, so now I remove the index from List2 since it's no longer needed, but now you know what's happened right? ListBox2's List indexes have all decremented by 1 because I just removed an item from the beginning of the list, but List2's indexes have stayed the same (at least that's how it appeared when I tested it).
So basically whats the best method for keeping things in reference? I was told about list boxes in another thread of mine, but is it really the best way to go about this, I can't seem to keep everything linked together reliably.

I am trying to draw textboxes when the user enters the amount of textboxes to be drawn on one form and the textboxes get displayed on the another form. I have found these codes online but it works with inbuilt codes I guess. That is, the number is already hard coded in the form.

I have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times
Public Class Form1
Dim sex As String
Function randomfirstname()
Dim infile As IO.StreamReader

I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?

How would i go about automating creating a new internet email account in outlook (2003/2007 or express) ? We currently have an application developed in miniPHPstudio (in PHP obviously) which we distribute to clients, and that sets up their email app with their account details and our servers details for them.

I'm wondering how I would go about generating a random number in VB.Net. As I am developing an ATM system for a bank, a randomly generated 4 digit PIN code would have to be assigned to each person.

Dim x As Integer = 0

I am trying to make a number be generated as this Windows Form loads, then the user guesses by entering a number and clicking a button to check whether it is correct or incorrect.
I have the code complete, I'm just confused on how to declare the random variable outside the button sub procedure so it only generates one time.
Here is my code.[code...]

I'm using VB.NET 2008 Express Edition and I'm trying to create a simple program that will roll a number of dice I choose. It does this by generating a random number within a specified range (I'm rolling 3-sided dice in this case so I'm generating numbers between 1 and 3) and adding each number to a textbox to create a total of all the dice rolled so far.
This is my
Private Sub butRoll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles butRoll.Click
Dim RandNum, i As Integer
Dim RandomClass As New Random()
'if at least one dice is rolled
If txtD3.Text > 0 Then
[Code] ......
Now the problem I am having is that although my random number generator is generating the right numbers (confirmed by checking the txtLastRoll textbox), when I add it to txtTotal, it seems to be getting another number from somewhere and adding that to my random number then adding it to the total and I have no idea how this is possible! txtTotal always starts as 0 but txt1 is not showing that. Normally I would just set txtTotal to 0 there but if I do that, I won't be able to add the numbers together. I've tried finding a pattern in the mystery numbers appearing in txtTotal but they just seem to be random.

I'm working with a random number that generates a price for a house between 1 and 100 dollars (obviously very realistic).
Dim Housecost As Integer = (Int((100 * Rnd()) + 1))
My problem is that I put that number in the public class which does generate the number but only once. But I need the number to be re-generated every time a button is clicked. Now I would put this code snippet in the buttons Sub but there are 3 other subs in the code that call for that randomly generated number and the only way that I know of that allows all the subs to read this random number is to put it in the public class. So how do I put the number in a place where all Subs can read it and can be called to re-generate when needed?

i'm importing a text file into a access table like this:
vb.net
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & frmMain.FolderName & ";HDR=NO].[" & frmMain.TextBoxFileName.Text & "]"
sql.ExecuteNonQuery()
my question is what is the best way to add an autonumber to the table? i currently do it like this:
vb.net
sql.CommandText = "ALTER TABLE [tblMailList] ADD COLUMN [ID] AUTOINCREMENT;"
sql.ExecuteNonQuery()
but when the file is too large i get this error: "File sharing lock count exceeded. Increase MaxLocksPerFile registry entry."
and yes, i have tried to change the registry entry and it didn't work:
vb.net
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesJet 4.0", "MaxLocksPerFile", "9000000")

I have 4 Columns in a ListView. The first one is called Serial No. Every time I populate it, the serial number increases automatically. After populating the ListView couple of times, I select any row(s) and remove it. When I remove one or more row(s) from the listview, serial numbers stays same. I want the serial numbers to be fixed automatically when I remove any number of row(s). How can I do that ??? Here is my code -
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.

I am trying to figure out how to capture the autonumber PK from the database when I add a new row to the table so that I can then load that value into a variable. I am currently using the IDE tools for my database queries (dataset designer), so if this is not something that can be done through that, I would need to know how to code my database query.
