How To Edit Line Values Within ListBox
Jan 16, 2012
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'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.

I have a program that reads a text file tab delimted using OLEDb I need to be able to allow the user to insert a user created record into the file which I can do. The problem is I need to be able to let the user edit that record. From my understanding you can not edit or delete with OLEDB only insert So I thought I would read the file using stream reader, find the line I want to edit and just delete it, rewrite the file, then let the user insert a new record?
Dim strDelimiter As String = vbTab
OpenFileDialog1.InitialDirectory = "C:\"
OpenFileDialog1.Filter = "Text Files (*.txt)|*.txt"

I am trying to speed up the process of changing flags within an INI file used for a program. Ideally i want a simple form with ON/OFF radio buttons which are specific to different options within the ini file. For example, if i wanted to turn Printing off in the ini file, i could select OFF for which this will edit the ini file and change the setting "Printer=0"
Code:
Dim file As System.IO.File
Dim reader As System.IO.StreamReader
Dim line As String
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged

Ok so i have a uni assignment to delete lines of text out of a text file, so far i have figured out how to search the text file for specific bits of text, i,e name of user, ive also used a loop to find out what line in the text file the specific line exists as...my
code so far is
Dim line As String
Dim Input As StreamReader
[code]....
the selected policy is what im tryin to use to write over the line of texts that already exists however i think that maybe instead of deleteting what exists it will just move it down a line and make a blank line

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?

So, 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??

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)?

I programmatically edit my datagridview cell values. I use the vertical scrollbar to find the row I want to edit, select the row then click an edit button that takes me to another form where changes to the record are made. I then click a button which saves the changes and returns me to the datagridview form. No problems here.
When I return to the grid, the records are displayed with the first record at the top of the grid. That is, the vertical scroll bar has repositioned itself to the very top.
Is it possible for the datagridview to "remember" the position of the vertical scroll bar so that when I am returned to the grid, the rows displayed are the same as when I left?

I have written some code to get the data from a number of text boxes all named in the style txb_[column name]
I want to write this data to a datatable.
The text boxes were initially filled using a row 'aIndex' from the datatable, then the user can edit the data.
When this code runs, the text boxes all revert to their initial values, regardless of any changes made to their contents during runtime.[code]...
