Multi Forms And List Boxes?
Apr 12, 2011
Ok, Im having trouble passing a value from one form back to another using a listbox... The user clicks a button in the main form to bring up an instance of another form (form2.show). In that form, the user then then selects a number 1-5 and then presses done:
Code:
Private Sub frmPlayer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
If lboNumber.Items.Count = 0 Then 'list box is empty
For x = 1 To 5
[Code]...
How do I pass that value back to the main form as a value when the user clicks done?

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..

The first list box contains the project name. Based on whatever is selected in the Projects list box, the 2nd list box is generated with Custodian names associated with that project. I am having problems generating the 3rd list box. This holds the data sources associated with whatever is selected in the 2nd list box (Custodians)

I am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.

In VB.Net 2010, is there any way to do multi-select in a drop-down/combobox, preferably with check boxes in the drop down? I've seen various discussions on the 'net about this but no such beast appears to exist within the tool.?

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

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'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

I have a list box on a form and it works fine for what I want to do.I am wanting to edit items on the form, this means populating the listbox and then selecting the relevant items.
My listbox contains a list of item sizes, i want to select the sizes which belong to the item being edited.
can someone give me some pointers.I tried me.lstItemSizes.SetSelected(i,true) but this only works for a single item.

The ListBox or the ListView
The Grid (I think it is the DataGridView)
Or anyother simple way of doing the stuff. All I want is simplicity.

I'm using VB.NET. I want to build a large List (Of MyClassOrStructure) that becomes static after its initial population.I'm going to have multiple threads that need to iterate through this list to read data (no writing, inserting, or deleting)
Are there any very bad things that I need to keep an eye out for?

i have having a annoying problem to do with loops.
[Code]...
When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.

I am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.

I have two list boxes created. One is Quantity and other is Price. When i enter price and quantity i want it to multiply and add one by one and give me the total in a label below...The problem is when I have two or more items in each list box I'm unable to come up with the total. I figured out that it will need a loop. So my question is that how should i use the loop. I haven't learn't how to make loops..

Background: ok I have an app that hides in the system tray. During its operations in the background it can try to invoke an outside app several times.. and I need to track when the call errors out.. I was using messagebox's but for some reason if the app hidden the messagebox's dont come up and goto the forefront. So in reading about this I read I should just use a form to do it.. so I did.. works fine.. well works fine for one error.. but if the user tries to do 3 of the same operation.. and lets say first errors.. second works and third fails.. using one error form wont work.. since I diaplay the error one.. then need to display error 2.. I need 2 error forms so they can click OK on both.[code]...

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?

If I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:
name = "Joe Smith"
listbox1.Items.Add("Name: ", name) [or something like this]
[Output] Name: Joe Smith
