Placing Selected/unselected Items In Checked List Box Into List Boxes?

Mar 16, 2011

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"

Multi Column List Box Array Resets Before Adding Next Values

Mar 13, 2010

When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]

Adding Items From List Box

Jan 28, 2010

I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.

It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

Adding Items To A List (of Object)?

Mar 28, 2010

I have some code that adds items to a List(of Object).

Here's my original code

Dim BeaconStoryList as New List(Of My.StoryType)
Dim BeaconStory as New My.StoryType
Dim NewStories() as New Foriegn.StoryType = GetStories

[Code]....

But as soon as the code assigned "Chicken" to BeaconStory.Title, then BeaconStoryList(0).Title would also change to "Chicken".

With my second version of the code this did not happen.

It's as though it was placing pointers into the elements of the array rather than values. If that is the case, however, then why does my second version of the code work - I'm still passing in the same thing - aren't I?

Adding Items To List Boxes?

Oct 19, 2010

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?

Adding List Of Items To Array?

Apr 14, 2010

I'm still learning VB.net and there is a bit of code I have added which is an array and I want to add a list of items to the array. If that makes sense. I have 6 classes two have arrays.

Here is the code from one of the classes
Public Function getItems() As Array
Return _LevelItems
End Function

How would I add the item list to this? Where do I put it? Like underneath it or in the items class? That code is in the Level class.

Forms :: Scroll To Selected Items In Checked List Box?

Apr 29, 2011

I've got a Checked List Box full of PC names that the user can check. I've also got a Combo Box that lists the location of the PCs - if the user chooses one of the locations in the Combo Box, it automatically selects all of the PCs in the Checked List Box that are at that location.

However, if that group of PCs are way down the list in the Checked List Box, you can't immediately see that they were checked.I'd like to know if there was a way to have the application automatically scroll/jump down to the area of the Checked List Box containing the PC's that were just checked.

VS 2010 Custom Type Array / List With Adding Items And Specifying Custom Type Variable

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]

Adding A List Of Items To A Listbox From A String?

Aug 18, 2011

I have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim start As Integer = 1

Adding Items To List Results In Duplicates?

Jul 29, 2009

I have this code to return a list of fund sources for our organization.

Dim FundSourceList As New List(Of FundSource)
Dim fs As New FundSource
If results.Count > 0 Then[code].....

The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.

For Each FundSource In FundSources
Debug.Print(FundSource.FundDescription)
Next

So I change the code to this. I moved the creation of the fs variable inside the loop.

Dim results = From result In dsResult.Tables(0) Select result
Dim FundSourceList As New List(Of FundSource)
If results.Count > 0 Then[code]....

This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again?

.net - LINQ Query For Filter By Selected Items In Checkbox List?

Jun 30, 2011

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?

I feel like I am missing a really obvious answer, but cannot get it.

For argument sake... here is the what I have for sample data:

In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3

Selected Types 2 and 3 in CheckboxList: filteredColors

Asp.net - List Box Selected Index - Various Items Inserted Depending On The User Selection

Jan 18, 2012

I seem to be having issues with the selected index on a list box.

The list box is having various items inserted depending on the user selection. An example would be:

LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")

LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")

[CODE]......................

This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex

I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.

VS 2008 Multi-threding - Adding Multi-threading Facilities - Cross-thread Operation Not Valid

Feb 10, 2010

I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.

When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.

It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

VB 2010 List Box Multi Select Loop

Jan 24, 2012

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.

VS 2010 PictureBox To Determine Items In Game?

Jan 21, 2012

[PictureBox] [PictureBox] [PictureBox] [PictureBox] [PictureBox].

All of them have no images. Now. I want to make an item editor for the game I'm playing. To edit the items, You have to place an ini file in the game's directory with the template below:

Quote:

[ItemSet1]
SetName=Set1
RecItem1=1028

[Code]...

And untill 6 - what after the = is the item ID. Each item has a unique ID for it (I have a list containg each item name and their ID).

Now what I want to do is: I have a listview on the left with each character in the game Image and Text. I also have a listview on the bottom with all the imgaes of each item and each text for the item.

I want to make it so when the user double clicks an item from the listview, It will automatically add it to the first picturebox (If it's empty). He can choose any item to add to one of the 6 picturebox's, When it fills one after one. When all the picturebox's are full, nothing will happen.

Now what I want is: How can I determine which "item" the user chose and according to that assign the item's picture to the picturebox, and then make a new ini file to set picturebox1's image's ID to RecItem1, picturebox2's image's ID to RecItem2 - and so on.
