Flashing A Listview Item?
Jul 4, 2009
Problem: 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*

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

Alright, So i have two forms open. One in a listview and i have another window with a browser control in it. The browser is adding data to the listview but i made it so it hides while doing this using Me.Hide(). I can make it appear if i click the menu item "Show browser" i made.when im on Form1 (the listview) and its doing its thing with the browser window hidden. It keeps making form1 flash. Well not flash but like the browser window is poping to the front (while hidden) causing me not to be able to click on anything on Form1.This happen everytime the web browser navigates somewhere.Making Form1 always on top fixes it, but it also gets on top of other programs like my web browser . I want it to be on top only to the web browser.

I have a datagrid with planned orders for loading (like the flight schedules at airports). If the status is "ready for loading" I would like that value to flash based on a timer. I managed to do it with text on a button, but because this is a datagrid it is more difficult for me and I am a bit confused.
Here is what I have for code;
Private Sub OrderOverviewDataGrid_CellFormatting(ByVal sender As Object, ByVal e As DataGridViewCellFormattingEventArgs) Handles OrderOverviewDataGrid.CellFormatting
If Me.OrderOverviewDataGrid.Columns(e.ColumnIndex).Name = "Status" Then
[code]....
Everything works fine. The column "Dock1" has the right color and the statuses have the right colors to, but; I want the "Ready for loading" status to blink based on Timer_2 which I have put on the same form.

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.

My 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")

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}

I'm writing an application to help manage an employee database. It displays the current entries in a ListView control using the SELECT FROM sql string and allows entry into the database using the INSERT INTO sql string. What I want to do is have the user select an item from the listview and be able to delete it from the database. How I'm trying to go about it is by detecting when the user presses 'Delete'. When they do, the program gets the string value of the item, hands it off to a variable, and the variable goes into a DELETE FROM sql string and deletes the row in the database.
I have multiselect disabled in the control so only 1 selection is possible at a time. I don't know how to detect the Delete key or how to get the string value of a listview item into a variable. If I know how to do these two things, I can work out the rest of the application. I'm still kinda new at this kind of stuff, so any responses will have to be dumbed down a little.

I have a bit of code where you can add a new field using an add button, which enable the asp:EditItemTemplate, but the thing is that this adds the field at the bottom of the list, making the user have to scroll down if there is enough items already in the ListView. How can I make the new item appear on top of the list?
ASP.NET CODE
<asp:ListView ID="[...]" runat="server" DataSource=<% [...] %> >
<LayoutTemplate>
[...]
</LayoutTemplate>
<ItemTemplate>
