Edit Items In Multiple List Boxes Simultaneously?
Jul 14, 2011
Using Visual Basic in Visual Studio 2008, I have created a Windows form with multiple tabs and questions. Each question has an associated drop-down listbox that the user will eventually click on to enter his or her response. My client has now informed me that she wants to change the standard responses in each response box. There are well over 100 drop-down listboxes, all with the same items, and they all must be changed.
I originally inputted the items using design view. Would someone please tell me if it's possible to edit all of these boxes in the design view simultaneously? When I control + click on more than one box, the Edit Items option that is normally available disappears. Is there a way to do it in code in a manner that would save back into design view?

I'd like to allow the user to select up to an entire column of cells and type and/or paste a single value that would then change the value of all the selected cells in the DataGridView to the value that was typed or pasted. I understand this is probably two separate answers, but perhaps if there is a way to set the contents of the clipboard with the value typed, I was thinking it may work well to identify both things I want to do.

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)
Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

I am surely a new self-learner programmer using VB 2010 Express edition and I have a problem on writing my first code. I have designed my form and I only want to add code as events. The IDE already adds the methods when I double-clicked the button which I want to add the code on.
This question may be good on the IDE forum, but I just thought to ask it here because there may be more experts here on VB language functions. I have added the MenuSctripItems such as File, Edit and so on. How do I write the code for New, Open, Save, etc under file menu? It may sound boring or even silly, but I am here to learn and your contribution is both for me, you and the MSDN.

I'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.
So, how should I be thinking about this?

I need to move items between two list boxes, I've never used list boxes before so this is totally new to me and I don't know where to begin, all I know is they work kinda like arrays.
So what I need is to move one or more items, from ListBox1, and move them to ListBox2 and vice versa
p.s. sorry to the mods just realised I havent been selecting a category to make my posts in, won't happen again.

In my project, I want to use Coordinates of a place (eg; London) which is selected from a list of several thousands of coordinates of places.
I thought of using comboBox / ListBox to display the list of the coordinates of places.
I want to know how to make this "editable"; ie: anyone using this program should be able to Edit / Add / Delete a coordinates of a place. And the newly added Place should be saved so that he/she can use it whenever it is needed.

My screen tends to seize for a few seconds while the list boxes are populated.I moved the call to the List Populate procedure to the form's shown event.This improved the performance slightly but not enough.Is there a method whereby I can ensure the form is fully loaded and displayed before the lists are populated?

I am trying to assign integer values to the items in 2 different list boxes called lstWorkshop and lstLocation. I then want the equation, intCost = intDays * intLodgingFee + intRegistrationFee, to be executed and the result to be displayed in a third listbox named lstCost. This is what I have so far, but whenever I run the program the value that always gets displayed is 0, which is obviously not correct.
Public Class frmWorkshopSelector
Dim intCost As Integer
Dim strTotalCost As String

If I have 3 times selected and when I click "submit" for example I want all my selected items to be removed, but when I try to do this only my first selected item is removed.
ListBox.Items.Remove(ListBox.SelectedItems)
How do I remove all 3 items from the list box at the same time?

On my form I have 3 textboxes. They get their data from a database query. The trick is the database may return 1 result or up to 3. If the query returns only 1 result, I want the first textbox populated, 2 results, 1st and 2nd textbox populated, etc... I also want to be able to track CurrentItemChanged Event for updating purposes. My initial thought was to use a list object as the binding source but how would I cycle through the list if it returns more than one so that I can assign the values to the 2nd and 3rd textboxes or if data is entered in to a blank textbox I want the currentitemchanged

I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String
strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith"
If strNames.ToString.Contains("Mike Brown") Then[code]....

I used different backgroundworkers to instantiate some 'heavy' forms thinking that it will reduce the time to instantiate them if I did them at once but it looks like I am wrong since it is still taking about 43 seconds to load all of them. Am I missing something or do you have a tip on how I can speed up their instantiation?

Not wanting to hijack 45minutes thread, I thought I might spawn a thread of my own based on his question.
PlausiblyDamp was kind enough to provide some generic code, which I have modified and attached.
I have made a few alterations mostly around removing random objects, as the game in question (Space Invaders) has a set amount of aliens and set starting positions.
As a start I have limited the UpdatedPostion to horizontal movement as the aliens only go side to side unless they hit an edge.[code]...

Problem is to run this application (WoW Private Server) I need 3 running applications. Is there a way to shell and wait 3 applications all at once. OR if i was to create a separate console application who's only job was to start the three applications at once how would I pass the application variable?

We are looking to design a security application that does the following on laptops:If the ethernet adapter is used (cable plugged in) disable/block all other network connections (wireless WIFI, mobile broadband (PPP), virtual VPN adapters etc)When ethernet adapter is not being used again, all connections allowed.We have looked in the WMI a lot but there are no good ways of doing this. Only disabling the network connection is not secure enough because most mobile broadband applications try to re-establish the connection. This should be an application that works on all laptop vendors without any user interaction (such as choosing interfaces etc..).

I want to play multiple sounds simultaneously from My.Resources in Visual Basic 2010. I have tried:My.Computer.Audio.Play(My.Resources.SoundName, AudioPlayMode.Background)
I have also tried using multiple Windows Media Player controls, but that also didn't work.The first sound is cut off when the next sound plays.When searching around the internet I found people suggesting using 'DirectSound', but there are only tutorials for DirectSound in VB 6.0.

I'm writing a program which gets the time and date from forums which only show "x hours ago" on the main thread list.What I do is get a list of threads, open their print version and fetch the info.I'm currently using a single webbrowser, because there's no control array anymore. This makes the proccess very slow.Is there a way to open all the threads' print versions simultaneously?(BTW, I'm using DOM functions like GetElementsByTag, so I'll need to get the page's "Document" object.)

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!
