Getting Values From Listbox?
Jan 14, 2009
I am very new to vb.net. I have been using vb6 for a while and I am making the leap.I have a list box that receives entries from another text box, there will be multiple entries, and only some will be applicable per record(its a report writing app).e.g. The user says ok I need this and that signer for this record.
lstSigners.Items.Add(strSigner + strSigner)
The entries that are needed are then selected via checkbox in the listbox. I now need to be able to capture which items the user selected.

I am using asp.net with vb.net. I have created 2 listboxes; lstselect and lstroles. List boxes lstselect contains all of the available roles that can be added into lstroles. How do I take the roles that have been added into lstroles and make them into a parameter to pulled into my database when the stored procedure runs?
Here is the code for how my list boxes share the roles:
Protected Sub btnRight_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnRight.Click
If lstselect.SelectedIndex <> -1 Then

I have five listboxes that are populated from five different datasources basically I have connected to an MS Access database and I am running SQL queries effectively so the five listboxes are populated via datatables for example dtInterests, dtHobbies, dtMovies, DtTV and dtMusic my question is how would I compare the values that are being stored in each listbox I want the application to check each of the five listboxes and if the value is the same (in my case the valuemember is the customer id) then store the result somewhere (in a textbox)

So i have some HTML like this[code]...
My problem is, i want to also get div id="2" value at the same time and add it to my listbox, since the Persons ID is in div 1 and the Name of the person is in Div2.
I was thinking i could do another for each loop, and just add the username behind the id i pull.
Question is, how do i add to a value or position in a listbox, after its been filled?

I'm trying to create a calculator that does this formula : Amount=Principal*(1+InterestRate) The point of it is to Calculate the compound interest earned over however many years the user selects between 1-15 from a listbox. The user also inputs the investment & interest rate. When calculate is clicked the results show in another listbox below.
year 1 $$$$$$
year 2 $$$$$$
etc
[Code]....
I stopped the code at Year 2 as it repeats the ElseIf to EndIf unitl selectedIndex = 15 & intYear 16.
it works for Year 1 but the problem comes with Year 2-15. it needs to take the value from the previous result in lstOutput and use it in the formula for principle.

I have a listbox that prints 2 different values each line. The first one is String and the second one is an Integer, (although I've converted it to String). How do I extract the first String value? One is suposed to be able to mark one line, and remove the selected lines values from 2 different arrays, and for that I need the String value.

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.

We have a listbox in our MVC View and the user has the ability to highlight multiple values. I'd like to be able to save those selected values(if possible?) as a comma delimited cell value in our '08 SQL Database.
The image below shows what I am attempting to explain. Note the selection in the LISTBOX
This is where we save the passed in values from the Positionnumber DDL (Listbox w/ mulitple highlights).
> <HttpPost()>
> Function Edit(wsmonitor As WSMonitor, ByVal vbpositionnumberDDL As Integer, ByVal PassedCounty As Integer, ByVal
> MonitorTypeDDL As String) As ActionResult

I'm building some lists of selected values from listboxes; it's easy to retrieve the text like so:
For Each item In Listbox1.SelectedItems
ParameterList.Add(Listbox1.GetItemText(item))
Next item
What is the corresponding way to return the value rather than the text, in the event that they're different?

I am working with a future value application and I am trying to display the calculated future values in a listbox. For instance, I input the monthly investment, the yearly interest rate and the number of years into textboxes and I want the application to list out the future value for each year until the number of years in which I entered is reached. I cannot figure out how to get the code to display the value after each year. I am trying to use the "mod" operator to display the value each time the 12th month comes around.[code]...

i am having trouble displaying the values i get from an IList(Of T) and displaying that in a listbox found on another form. I have used a for loop to get the values from the IList, then i can display that in a msgbox. for eg:
Dim j As Integer
Dim path As String = ""
For j = 0 To best_tour.Count - 1
[code]....
best_tour is ot type IList() path keeps the name found in the list everything works fine inside the loop..but it does not populate the lst_output listbox.I have tried using files, but in vain. It just get the values from the list but does not display that on the listbox.If that can help, then listbox is found in a panel on the form2, but taking it out of the panel does not affect anything.

Is there a way to to combine line's 1 and 2? I only want to loop through a list of the selected items in this listbox. This works just fine, I just wondered if there was a collection of selected values returned that I could use to avoid having to do it this way.
For Loop1 = 0 To MyListBox.Items.Count - 1
If MyListBox.Items(Loop1).Selected = True Then
