In my listbox I get a collection of strings in this format:02406L101G0,967S or 12010C2100,978U. I should get this list on a regulated manner.haracters in the seventh,eighth and ninth place (from left side) always make the numbers eg: 101 or 210. Is there a possibility to edit the list of strings (in listbox or a listview) in accordance with the number obtained as a substring (7, 8 and 9 character)?
View 9 RepliesCurrently I'm doing a resistance calculator. If i got 3 combo boxes which let user to choose the color code of a resistor, how to make the resistance of the resistor(resistance after count according to the color code choose by the user) go into a listbox after click "Enter" button? And also initialise the color code choose by user just now and the resistance after count.
View 2 RepliesIf I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False

How to put an arraylist inside a listbox but that's already solved. [URL]. There is all my code, so I need to be able to edit the selected customer, clicking on customer>change from the Main GUI. Then the CustomerFrame GUI should open, and all the texboxes should show the information that is in the listbox. There I need to be able to edit the customer and save it again.
I know this is the Code to display the item selected from ListBox in a TextBox
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = ListBox1.SelectedItem
End Sub
But that's not all I need to do, the index of the listbox is divided into all the items of the arraylist. There is the complicated part. How to divide each item of the arraylist into individual textboxes?
I am just wondering how I can make a listbox count the number of selected items and display it in a text label. My listbox selection mode is on MultiExtended.

I am using vb 2005. I have items in a Listbox. I want to rename a highlighted(selected) item just like same way the Window Explorer. (clicking the highlighted item, then the highlight is gone and the item string is put into rectangle box and ready for type-in by user.)
View 2 RepliesSo, I need to be able to edit an item that has been selected in a listbox. I need to do so with a button click event. Theoretically, I know how to do this, because I know how to add an item, and how to remove one, and how to insert an item at a specific location.
'Dim strinput As String
'Dim Item As Object
'Dim index As Integer = lstList.Items.IndexOf(item)
'strinput = InputBox("Edit This Item")
'lstList.Items.RemoveAt(lstList.SelectedItem)
'lstList.Items.Insert(index, strinput)
however, this does not work at all. what am I doing wrong??
I have items in a listbox. I want to be able to modify a selected item in the listbox once it is highlighted, and the the modify button is clicked. A dialog box pops up with the selected listbox item in the listbox and is able to be edited.

I am loading a listbox with lines from a txt file. Now I would like to be able to edit values within that listbox by going there with the mouse cursor and type a new value..
E.g. the listbox displays:
7226218; Hemlock; 22.55; 4
0822722; Pine, Sugar; 11.55; 7
After editing it looks like:
7226218; Hemlock; 22.55; 2
0822722; Pine, Sugar; 11.55; 7
After pressing an "accept button" those values should then be written back to the txt file.
i got no clue how to edit ListBox items with an NumericUpDown Tool I need to change the selected item in the listbox example->
"7226218; Hemlock; 22.55; 0"
Into -> "7226218; Hemlock; 22.55; *numeric box value*"
After the Add to orderlist button is clicked. It has to replace the old ListBox item and it needs to be saved on a TextBox (the order editor) on form2.
- And order of 0 items may not be accepted
- When nothing is selected, and user presses the "Add to orderlist" button, the program must not be exited with a crash.
- The order (orders.txt) must not be made at start-up, but when the first order is placed.
- When a order has been made, the only way to correct the number is to edit the order.
- When an order is placed, it must directly be put in orders.txt.
- The order must exist after the program has quit.
- You cant order the same thing two times.
- When u type a number by hand, the button to order must be usable.
- The can only change the order amount in the edit program.
My uncompleted code:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")

I'm using a Datagridview to fetch information from an XML. Each row contains a separate entry. I can read from and append to the XML database, but I want to:
A) Be able to save any edits made in the database to an XML file.
B) Store and fetch a collection of possible variables to populate a list box.
A should be relatively easy, but I don't know if B is. The XML database will contain hex values that can be written to predefined offsets, and each could be any number of bytes long. So one entry in the XML/Datagridview database could read "00,0A,0B,0C", where commas separate available write values, with each possible value being another line in a listbox. When a value is picked from the listbox it will be written to the XML.
I don't want to have to make <ListBoxValue1>, <ListBoxValue1> in the XML for each possible entry, so I'm hoping there's a more efficient way.
If you're interested in what I'm making, it's a hex editor that loads descriptions of offsets from an XML, then loads the values for each offset from a file. Here's a screenshot.
im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox
textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text

View 6 RepliesI have an app where i have two list views
[Code]...
I clone the information to the empty listview2 from populated listview1 adding quantity via a numeric up/down. That works to a certain extent but problem is it adds another instance of the added item each time I press buy. I would like the items to appear in listview2 according to their index value in listview1. And when I press buy the app change only the quantity in column 2 if the item is already in listview2, if not just add the new item.
