VS 2008 Determine How Many ListView Items Are Selected
Oct 15, 2010
I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

Using VB.net 2010 i am trying to figure out if an item was selected or not. Reason being is that if the user clicks on an item and pushes a button then everything works just fine. However, if the user selects an item and then clicks on a blank spot on the bottom of the listview and then clicks the button then it crashes.
My code is this:
If (lstMaster.SelectedItems(0).SubItems(1).Text) Is Nothing Then
MsgBox("test")
End If

I have a Listview that will display all System Services on the local machine. I also have settings to change states of the services as a group as well as single selected item. My question is, Is there any way when the user selects which option to change, to highlight all the services that were changed in the listview, making it easier to see what the user has changed .

I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

I know that the "SelectedItems" in a ListView are a collection of items and therefore can not be converted staight away for instance into a string. How does one go about selecting just one of the items in the list view?My list view contains 3 columns/items: First, Last and EMPID. When the user selects a row in the listview, I need to pull out the EMPID item as a string variable.

I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.
For i As Integer = 0 To ListView1.Items.Count - 1
Dim ftp As New FTPclient(host.Text, username.Text, password.Text)
ftp.FtpDelete(ListView1.SelectedItems(i).Text)
Next
Some info:
The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.

I have a multiline textbox in which i add values to.A button is pressed to put these values in a listview in the first column.I then have 5 or 6 other comboboxes and textboxes that will send information as subitems to the listview, only if the original item in the listview has a checked box. The code i currently have is just adding the subitems to however many checkboxes are checked.I am trying to get the subitems to add to all of the items that have checked boxes rather than creating there own rown underneath the checked boxes.[code]

I have a Form with listview of customer name. e.g. AAA, BBB, CCC, DDD, EEE. etc And 3 textboxes.
I want to be able to populate the textboxes when the user selects a customer. For example: If User selects AAA, textbox1.text = AAA, then if User selects CCC, textbox2.text = CCC etc.
I tired: (in a button on click event)
TextBox1.Text = Listview1.SelectedItems(0).Text
TextBox2.Text = Listview1.SelectedItems(1).Text
TextBox3.Text = Listview1.SelectedItems(2).Text
But this only works if the user selects 'all' 3 customers at once. I want to allow the User to populate each textboxes depending on how many they select eg. 'Upto' 3 customers .

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?

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.

I've been working with a listview. I just need to know how to get the index of the selectedindex otherwise I can't work anything out, if the application doesn't know what is selected... I tried these codes but none tells me the index, I am just lost with it, thought shouldn't be that hard...
Dim index As Integer
Dim item As ListViewItem
lsvOrderDetails.SelectedItems.IndexOf
item = lsvOrderDetails.SelectedItems.Item()
