Can someone help me with this code? I just need to make it so there is no limitation on how much data is loaded in the columns or rows, it populates very nicely for smaller comma delimited files , but if I try to load something that goes for example over to AV column, it errors out.I don't care about VIEWING this data, I am just trying to get it into a LISTVIEW so I can access the data for other methods in my code.Index was outside the bounds of the array. [code]
I am trying to populate listview with the code below:
Public constr As String = "Data Source=adesina-pc;Initial Catalog=AdventureWorks;Integrated Security=True" Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
I have started the familiarize myself with WPF and have gotten stuck with the ListView I've read a lot of documentation about binding and I can't seem to find how to populate a ListView programmatically. It seems like a lot of work to create the binding and classes, etc, just to fill a ListView.
1. If you want to populate a ListView with data that a user has inputted, is the correct way in WPF to populate the ListView with binded data?
2. How do you add items and subitems to a ListView in code? (There doesn't seem to be a subitems in WPF.)
I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade. When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows Dim lvi As New ListViewItem(dr("StudentKey").ToString) For i As Integer = 1 To 4 lvi.SubItems.Add("") [Code] .....
But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.

Im desperately trying to populate my Listview called "Listview1" with my stored procedure that I have create on my SQL Server 2005. Ive got quite far as seen below but I still dont know to to effectively populate the Listview1 with the data retrieved from my Stored Procedure. The below connection does work but I dont know how to use it now with my Listview.
Imports System.Data.SqlClient Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I'm playing with an Access database file. And I want to populate a ListView control with Access data. I'm not going to use the DataGridView control. The following is my Access file, which has a table labeled Employ1 with three fields (Usernames, FNames, LNames) as you see below.
I googled, searched and tried houres but I can not find a simple code/class that does the following: I have a SQL database and I want to show some colums of a table in a listview... Not so difficult I thought, in VB6 it was fixed in 2 minutes but now I'm struggeling for houres... I found Imports System.Data.SqlClient but further then this, I fail...
I have a tab control in my form and inside it I put a listview. What I wanted to do is populate the listview everytime I clicked on each tab. But I don't know how to do it.
Here is the bit of my code
Public Class Form2 Private Sub PopulateRecords() Dim TSR As New ADODB.Recordset Dim STRSQL As String = ""
I want to show a list of files and folders (names + their icons) inside a given directory with a ListView control or equivalent. I understand that ExtractAssociatedIcon gives you the icon of a file, not a folder. So what are my options for this objective? I don't really have a problem if I have to separate folders and files like the following.
Dim fi As New IO.DirectoryInfo(f) 'f is the path of a given directory For Each subfolder As IO.DirectoryInfo In fi.GetDirectories() ImageList1.Images.Add(My.Resources.FolderIcon)
if this question has already been answered many times, but I am new to VB and I don't really understand any of the examples I have found by trying to research this topic. I am using VB 2008 Express Edition. My List View is called listView.
What I want to do is gather the data that displays in my listview (called 'lstData') when selected and populate my textfields with it's information.[code]
Here is the code I am playing around I am getting error populating the table cells into my listview. In my codes it is always add only in one cloumn in my lv.

I am writting a vb.net program that I want to read in data from Excel and then populate a multidim array with it.I have been able to import the Excel data into a DataGridView (haven't been able to go directly to an array). Now I am trying to loop through the DataGridView to populate the array.This is were I am having troubles.[code]
I have to convert what i put into an input box, and somehow convert that into an array.
My project is to put in some random numbers from an inputbox into a listbox, then somehow converting those numbers into an array and find the median of those numbers. I'm able to do the math, and I'm sure its probably 2 or 3 lines of code
I am trying to design a little application that allows user to enter daily attendances for 4 weeks.exercise 11, Murachs beginning vb.net) The form consists of a combo box that list the number of weeks, text boxes to enter daily attendances fro mon - fri, a button to save the entries, a button that calculates the average weekly attendance and a button to close the form.
The issue I am having is saving the user entries. I use a 2 dimensional array with 4 rows and 5 columns. Within the click event of the save button I user a for loop to loop through the array and populate each dimension depending on the week selected. Once they are saved I clear the text boxes, set the combo box index to the next position , I.E selecting the next week unless it is week 4 hence the limit has been reached. Finally move the focus to the monday text box.
When I run the code I keep end up with 2 errors depending on how i change the code. The first is that i exceeded the index of the array and the second is that "" cannot be cast to an integer. My code thus far is shown below. I have edited the data so much that I am now just confused.
I'm sick today and cannot think straight but I have to get this done. I have an array: newarray() I need to populate this array if a condition applies as such:
Currently I'm trying to fill a 3x3 square with random x's and o's to make a tic tac toegame. Unfortunately the game doesn't seem to output all the x's and o's. Logically, from what I can see, it should be able to but it's not.
Shared Sub twodimension() Dim tic(2, 2) As String Dim min As Integer
how to go about getting data populated from a data grid view to an array of structures? I have a data grid view with 6 fields and 10 records that match elements in my array. I declared a list of songs based off of my structure Song.
I made a quick search but couldn't find any help I need to put the values of a checklist box into an array. I've found several solutions on the internet but all of these don't seem to work for integer arrays. This is what I've got so far
" Dim RemoveValues(checklistRemoveBrew.CheckedItems.Count - 1) As Integer Dim C As Integer For C = 0 To checklistRemoveBrew.CheckedItems.Count - 1 RemoveValues(C) = checklistRemoveBrew.CheckedItems(C) Next "
