I can't find a proper answer on how to update the ListView after I inserted another item. When I add ListView1.Clear() and DatabaseSelect() in Button1 there was nothing to view.
How do I refresh my ListView everytime I insert new items?
Here is the code of filling the ListView:
Function DatabaseSelect()
Try
myDA.SelectCommand = conn.CreateCommand()

I had a form here with 3 texboxes, 1 combox and 2 dtpicker. When I tried to update my database with this code:
Dim cn As ADODB.Connection
Dim rst As ADODB.Recordset
Dim Con, sql As String
Dim i As Integer
Con = "Provider=Microsoft.jet.OLEDB.4.0;Data Source=C:NOSDE\_MDBNOSDatabase.mdb"
[Code] .....
All of my records has change. for example I have a 5 records of different people, I've pick the first record and update it, then after I've save it, the remaining 4 records change with the same name as I pick the first record.
I load a bunch of files into a wpf listview and want to update the content of the listviewitems after loading the files, eg:
1. load the files from a directory into the listview - that's okay
2. Start a background worker and replace the full filename with only the filename and extension on each listviewitem. How could i achieve this using dispatcher or background worker?

View 6 Repliesi have 2 queries in vb.net with an if clause -
if x=0 then
insert into table1
else
update table1
both queries have 5 fields. now what i want to do is after this insert or update takes place, i need to look at this inserted/updated record and compare it with another table (table2). Especially for update, i have 5 fields in both tables. if any of the 5 fields dont match with table2, then i insert a new record in table 2 which is the updated record in table 1.
If i try
ListView1.Sorting = SortOrder.None
ListView1.ListViewItemSorter = Nothing
ListView1.Items.Insert(0, "0")
ListView1.Items.Insert(1, "1")
ListView1.Items.Insert(0, "2")
ListView1.Items.Insert(1, "3")
If ListView1.View is SmallIcon , LargeIcon or Tile it dont work (Display 0 1 2 3). If it's in List it works (Display desired 2 3 0 1).
Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
[Code]....
I am using VB.net (FormView and ObjectDataSource) and Sql Server 2005.

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

Do I really have to go through all this just to find out what item has been selected in a ListView?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?

View 1 RepliesI have a listview with 4 colunms
Private Sub process()

I've currently picked up a small project and they one who assigned me to it wants me to upgrade the app using .NET.Is there any way I could add an item to a listview when I'm not on the form containing it? In VB6, something like this would work.
'Code on Form2
Form1.ListView.ListItems.Add "Item Name"
but in VB .NET, the code below doesn't add anything to the listview. It doesn't return any errors too.
Form1.ListView.Items.Add "Item Name"
And another thing, why is it that when I close the Login form to launch the Main form, the Main form closes automatically? The code in sub main is
' shared sub main
Application.Run(New frmLogin())
Then when correct credentials are given to the form, I'll do this.
'login form
Dim frmMain as frmMain = new frmMain
frmMain.Show()
Me.Close()
I assume things are done a lot differently than VB6.
I have a ListView with two columns, first column contains a list of urls and I want the second column to display the google pr for each url. I already have the code to get the pr but I am not sure how to add that value to the ListView sub item(second column)

View 4 RepliesMy overall goal is to add fake/unbound items to a listview control (for final HTML Table output reasons). This is a code behind solution. Users will not be adding items as it will be outputted in a rigid table.
I have looked at several examples and while this is easy for a dropdown it is not for listview.
The code below works without error, but my item is not shown on runtime. I think the class is not setting the item fieldname correctly, but I can't figure out the right syntax to fix it.
ColumnNameAList.DataSource = PeriodDataView
ColumnNameAList.DataBind()
Dim test As New Example1("ColumnNameA")

View 6 RepliesProblem: I have a listview control that gets populated with devices that are offline and after so many failed attempts, it will begin to flash, alerting the user.The code I use currently works, but seems almost random. The first time an item is added, it flashes just fine. Once a second device gets added, both items will stop blinking. A third item being added causes only the 3rd item to blink (first 2 still not blinking).
Here is the code I am using.Question 1: Why is this behavior like this?Question 2: is there a better way to have a list item "flash"?*After so many failed attempts, it triggers a timer to start, and in the tick event is this code*

This is probably easy as well. But I have this listview which contains exe files I've listed up. Now, I want to execute these exe files in turn from which items are checked or not. So, I've tried this:
For each item in listView1.CheckedItems
Msgbox item.ToString
Next
Cause I noticed that the item in checkedItems doesn't contain much. And if I convert it to a string, it ends up in the msgbox looking like this: ListViewItem: {Filename.exe}
In fact i can loop through items of listview and determine items(i) is selected state or not. But i want to ask you is there method similar listview1.currentitem.text for instance.
