Multiple Listboxes Not Working
Jan 30, 2012
I have four list boxes, side by side. I've got a huge list of files that the program scans through and if (file insides) = (this) then; else if and etc. I know that part is working. The problem is actually the list boxes themselves. The reason I know this is:
I have four listboxes side by side, only the first one shows data, but if I delete the first one from the form, only the second will show data, if I delete first and second, the third one displays data, and if I delete the first three, the last one shows data. The problem is they wont display data at the same time. I was talking with someone else and they said I needed to change the IDs and I should see that option somewhere near the "Name" section. I use Visual Studio 2010... I don't see any IDs option to change. on how I can change this ID or maybe something I have to do to get these listboxes working?

I am pretty sure that I understand what needs to be done here but I'm not 100% sure on how to go about this.I have a list box that contains a list of url's for websites. 100 to be exact.I have a web request defined in a private sub.What I need to do is to loop through the listbox1, grab one url, place it into the variable of the request and then save that entire web request (with link) to string.In the end I will have all 100 url's put into their own web requests and feed back into an array which I can then put into some sort of multi-threading method.

I'm writing an application in vb.net 2008. It's basically a randomised image quiz. I have saved questions, answers and time taken to answer questions into 3 listboxes: listboz1, listbox2 and listbox3. I'm trying to add the content of all into a csv file. This is my code below which only saves the contents of one listbox to a txt file. How do I get a combination of all listboxes in the file with format (L1,L2,L3)? I alos want to add the user name and the date the test/ quiz was taken.

I am compiling a quiz, so the question number, user response and time taken to answer questions are sent to 3 listboxes. I wanted to save the file name (from the login form, date and listbox contents to a text file. I have scoured numerous codws...none of them work..all with errors. I have tried to look at Streamwriting listboxes. But can not find a way to add multiple listboxes to one text box. Actually none of the codes (including the Sub SaveToKnownFileWithDelimiter (below) I have looked at work.
This is my quiz code so far....
Public Class Form1
Dim intPic As Integer
Dim pickedImg As New List(Of Integer)

I have three listboxes with vertical scroll bars. I'd like it so that when one is scrolled, so are the others. However, I can't seem to find a "scroll" event. I tried this:
vb.net
Public Scrolling As Boolean
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
If e.Button = MouseButtons.Left Then
[code]....
It works when you click and drag on the listbox area where the items are, but not when you click on the scroll bar!

I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]

I have a couple of questions regarding the use of multiple forms within a single project.I'm currently using a button to load a second form so that the user can select different options and then load those options from the first form.Basically, I have a check box on form2 and I want form1 to be able to know if it is checked. I thought I could just use:
if CheckBox1.Chcked = True Then
Etc.
End If
But, when I do, I get an error saying it can't identify the object I'm referencing.Also, when I open the second box and I click my "OK" or "Cancel" button, the page reloads and then I must press it a second time for it to actually close.This is the code I'm using on my first form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim frmDialogue As New frm2Toolest
frmDialogue.ShowDialog()
If frmDialogue.ShowDialog() = DialogResult.OK Then
[code]....
The second form that has the buttons:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
Me.DialogResult = DialogResult.OK
End Sub
[code]....

Im very new to programming all together, but Ive recently been messing around with Visual Basic 2008..
1. When using multiple forms, how do I make a form be the form that opens with the program (default form?)?
2. How do I assign a button to open a second form?
With what I'm trying to make, I have both forms ready, I just need form2 to be the one that is the first to open when running and I need the code for a button to open form1.

How would i reference a control or form from another project. I have a solution with multiple projects (Project1 & Project2 for example) and I want a button on Form1 of Project1 to open Form1 on Project2. I know if they were part of the same project it would simply be Form1.Show() and I thought something like Project2.Form1.Show() would work but unfortunately it doesn't seem that easy.

I trying to do a drag drop from a listview in one form to another instance of the same form (same application running twice).I have it working with single items selections, but I want to make it work with multiple selections. 289508(VS.71).aspxThis works if I drag/drop onto itself (the same form), which I don't want, but I need it to work across instances.During debugging it seems the code DragDrop code just quits at the line during the drop:Dim myItems() As ListViewItem = e.Data.GetData("System.Windows.Forms.ListViewItem()")Any ideas what is wrong or how to drag/drop multiple items in a listview between apps?
here's my code:
Private Sub ListView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles ListView1.DragDrop

so I have a generic list in a console application. Dim Channels as New List(Of Chatroom) Chatroom is a structure. But I have multiple classes, threads, and timers looping through this list, sometimes at the same time, but it always seems to raise errors because the number of items in the list gets changed while one of the other classes/threads/timers are looping through also. Is there any way to allow only one to manipulate it at a time?

First my prog scan a specific path "C:music" which contain Mp3. Then it takes the MD5# of all mp3 and put it in a listbox1. Also on the formload it does open a ".txt" which also contain MD5# that goes into listbox2.Now this is what i am looking to have :When i click my button it compare each line of my listbox1 to listbox2. If , for exemple , the first line of listbox1 is already in the listbox2 then it delete the first line of listbox1 (listbox1.items.removeat(0)). And Do until listbox1.items.count = "0".

I have a program I'm trying to put together to allow my employees to submit shift reports. I'm doing this simply to make my life a little easier as this way, they will all be formatted the same. Instead of spending a large chunk of my afternoon thumbing through a bunch of differently formatted reports.
One feature that I need to figure out requires that one listbox can see what another is doing. Here, let me try to explain..
I have one list box that keeps track of EVERY action the employee does on a customers account. (cancel, upgrade, downgrade) and then a hidden listbox that JUST tracks "cancel" actions..one for "upgrade" actions and one for "downgrade" actions.
The reason behind that is that in the shift report, the all need to be listed separately. This way, I can just add each list to it's own array and list them where I need to.
The problem I've run into... If an employee handles an "upgrade" action at the beginning of the day..and then later on the upgrade is canceled, I can easily remove it from the main listbox that shows everything, however, I can't figure out how to find it in it's own listbox. The "Upgrade" box.

So unfortunately, on the shift report, it's still there even though it's gone in the program as far as the employee can see.The item in the main listbox doesn't have the same index as the item in each individual list boxes so I can't just tell it to remove the item at the same index..

I've got my first ever program and it's working. Having tested it a bit it would be helpful for the user to be able to copy the results printed in a listbox into an email or text doc. Just somewhere where they can make a note of it really.Is there something I need to do to enable it? All the google results I found were referring more to doing this in code. I literally want to be able to support Ctrl+A, the Ctrl+C straight out of the program to wherever the user wants.

I am starting to feel completely dumb when it comes to VB.Net coding. I am using Visual Studio 2010 and am trying to compare the numbers in 2 listboxes. If an item from list A matches an item from list B, I want it to add that item to List C. Once it has added the item to List C, remove those searched items from list A & B. Continue until it runs out of numbers to check.
If you are wondering what I am trying to do, I want to make a Common Factor list. I already have the Factoring list done, but got stuck here.
So far, my code looks like
Private Sub CommonFactors(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_Common.Click
Dim BoolAdd As Boolean, i As Double, j As Double
