VS 2010 - How To Get Values (Not Text) From ListBox
Dec 16, 2011
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?
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 For Each item As Object In listarrays.Items If item.ToString = Me.TextBox1.Text Then
[code].....
use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?
I have this code so that when you check a checkbox it drops the item value into the textbox. What I would ultimately like is for the items to be inline and followed by a coma. Atleast on the same line.[code]
How would I go about reading a textfile, finding values and using the values in the program?Now I want the program to read the text file, find [1], use the first line after [1] as value for a variable, and the second line as value for another variable. After that I will run some code with the values and then do the same thing again for [2] etc.
I've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
Private Sub saveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles saveButton.Click 'save the new vote choices to a file Dim votes As IO.StreamWriter votes = IO.File.AppendText("votes.txt") Dim voteSelected As String = CStr(commercialListBox.SelectedIndex) [Code] .....
I am using VS 2010 and I want to read the Text File values and place them into variables. This is my code Me.OpenFileDialog1.FileName = Nothing If Me.OpenFileDialog1.ShowDialog = System.Windows.Forms.DialogResult.OK Then Me.TextBox2.Text = Me.OpenFileDialog1.FileName filename = Me.TextBox2.Text End If [Code] ..... I am unable to move pointer to next line.
I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
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 have bound a listbox with a dataTable Now i want to move the values from the listbox to another listbox.i have changed the selectionMode of the listbox to multiple.So they choose multiple items and they get moved over to the other listbox.
for each item in listbox1.selecteditems listbox2.items.add(item) next
i get system.data.datarowview in the listbox2 how could i replace that with the actual value ?
I am starting to learn reading and writing to textfiles. One quick problem. My code here
'Read is the variable that will read the kp.txt file" Dim read As IO.StreamReader read = IO.File.OpenText("C:2/kp.txt"[code].....
however when it is read into the listbox those 3 words appear on one line in listbox How can i make it so that each line of the textfile is placed in each line on the listbox?
1.In my program I have 2 textboxes.In first textbox user need to put some number.Let's say he put number 10, then in other textbox program need to write numbers from 1 - 10, like this:
1,2,3,4,5,6,7,8,9,10 If he put 20 in first textbox, in second textbox it should be:
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 have a ListBox which is retriving mathematical data form a Texbox. I would like to know how to get the ListBox to automatically calculate all the mathematical data (finding the sum of all the data )
The following is the code that i used to store all the values in the listbox ito the access database.but it is not working.I didn't get any error.but the values in the listbox is not being stored in the database.The field in sample table that stores the value from listbox is a multivalue field.[code]...
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)
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 list box which gets populated on the first run of the program by the user. On the next run it needs to be completely cleared so new values can be displayed.
