Add Item To ListView While Continuing Other Code?
Jan 22, 2011
I have coded a low-level mouse hook. Each time the user clicks (let's say) the left mouse button, a custom event gets fired which is then handled by a form in my application. On the form is a ListView control with the following columns: Time - Application - Button.
I want that ListView to contain the last 1000 mouseclicks made, so each time the CustomMouseClickEvent gets fired, I check for the itemcount of the ListView, I add an item to the ListView and I resize all three columns. Problem is however that this extremely delays the processing of the mouseclick messages.
I'm wondering if it's possible to raise the CustomMouseClickEvent and then handle it in my application while at the same time the mouseclick message is passed on to the next hook to get processed by the systen?

Out of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

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?

Purpose: The user enters the item name and amount of the item purchased. The program calculates the tax for the item and the final total, and then displays these values. Tax on all items will be 7.75%.
And so far i've this code but it's not working:
' Program: Cash Register

' Purpose: The Cash Register Window application will
' computer the tax and the final cost of a

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")

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*

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 have a listview in my program that lists a couple of items (that the user adds).
How can i access the names of the items in the listview?
Say i have 5 items, in a listview with 3 columns.
When the user clicks a button a loop starts which displays a msgbox with the name of the items (column1) , one after one.
How would i succeed doing that?
