Assign A Value To Each Of The Items In The List Box?
Nov 19, 2009
I am creating a program with a few listboxes. And I want to assign a value to each of the items in the list box. Here are what my listboxes consist of and the values i want assigned to them.
Listbox1
Playstation Value is 100
Xbox Value is 90
WII Value is 80
[Code]....
I then want to take the values add them together and display them in a text box. So for example someone chooses playstation and call of duty that will be 130 and I want this to display in a textbox.

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

So, I'm working with Betfair API and I'm trying to use a listbox to display some data, for those who are familiar with it, it's the markets names.
I'm using this code and it's working great so far:
Sub Markets()
Dim oMarketsReq As New BFUK.GetAllMarketsReq
Dim oMarketsResp As BFUK.GetAllMarketsResp
With oMarketsReq

I'm building a virtual blackjack game and I'm having difficulty assigning values to the cards. I've set up picture boxes for the dealer's cards and the player's cards, and i've linked those picture boxes to an ImageList that contains all of the cards (+ the picture of the back of the card, since you only see one of the dealer's cards to start out with). When you hit the "Deal" button, I have the following code so far:
Private Sub btnDeal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeal.Click
Me.btnHit.Visible = True
Me.btnHit.Enabled = True
I have a section at the top that has labels saying: "Dealer's Showing ______", "You're Showing ________"how to assign values to the indexes/items of the imagelist? For example, items 0-3 have a value of "2", items 4-7 has a value of "3", and so forth...

So I am able to get the comboBox populated with the proper list of "clientLocations".
However they all have a valueMember of 0; thus the issue at hand is properly assigning the value of the comboBox items to the database column (which is returned in the dataset) rather than just the name.
Private Sub updateClientLocationComboBox()
'clear list
comboBox_clientLocations_deviceList.Items.Clear()

I wish to create a drop-down list box with items in it. Easy to do and done that. What I also wish to to is assign a numerical value to each list item. I believe under VB6 is was done using the list's `Value` property to set and get the item. It's so I can write a one byte value to a file but display a text value on the form. Don't wish to mess wish classes and arrays, but if I have to I guess it'll be have to be done.Was looking at some examples of making in-memory arrays/datasets for a list-box but just sees like a programming overkill for the simple thing I wish to do.Put it another way....
List box item 1 = "First option". List box value 1 = 35
List box item 1 = "Second option". List box value 1 = 44
List box item 1 = "Third option". List box value 1 = 3
If the user selects "Second item" from the drop down list box then that property do I use to retrieve that list item's value `44`. Also, when I pprogramatically populate the drop-down list, how to I set each lite item's `Value` property accordingly. As in the example 35, 44 and 3 Tried using `SelectedItem` and `SelectedValue`?

I am trying to develop a recipe manager that allows a user to create a shopping list. I've already determined that I want to use a list view for this job. I want to be able to group the items in the shopping list by the appropriate grocery aisle (i.e. Dairy, Bread, Canned Goods, etc.) I'm not sure how to assign the items to the appropriate group as the user selects each item.
I haven't started actually building the application yet as i'm still in the development stage, but i have been testing the list view out to figure out how it works. i've figured out how to add items. i just don't know how to specify the group that each item should belong to.

I have a user defined structure in a list that I am trying to change the value for in an individual element within the list of structures. Accessing the element is not a problem. However, the compiler complains
"Expression is a value and therefore cannot be the target of the assignment"when I try to update the value.For example:
Public Structure Person
Dim first as String
Dim last as String
Dim age as Integer

I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

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"

Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?

I have two generic lists, named ListA and ListB. Both ListA and ListB could potentially have duplicate items. What I would like to do is use LINQ to grab the items in ListB that are not in ListA, but I'm unsure how to do so.

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want.

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

i am writing a program that reads a excel report from accounting software with our weeks orders on... so basically the program reads a list of around 100 items which all works fine.I also have a database that holds info on each item, when the excel sheet is parsed the software checks to see if any new items have been added to the list that are not on the softwares database. this is where i am having the issue.I have two lists: ItemsOrdered & ExistsingItems.
All the items ordered this week are in ItemsOrdered and all the items not in the items in the database are in the ExistsingItems list. using these two lists how can i find items that are in ItemsOrdered but not in ExistsingItems.
