Help needed - Visual Basic .NET

Hi again, I have another problem that needs to be solved.
How do you loop through a ListView and check if strName is the text of one item?

Dim i As Integer
For i = 0 To ListView1.Items.Count
   If ListView1.Items(i).Text = strName Then
      MsgBox "Matches"
   End If
Next i

Please help, I am getting mad about this.

Have you tried: (untested)

ListView1.Item(i).Value = strName
or
ListView1.Items(i) = strName

Viewer.Items(i).ToString

The thing is:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll

Additional information: Specified argument was out of the range of valid values.

When running this code:

For i = 0 To ListView1.Items.Count
   If ListView1.Items(i).ToString = splNick(0) Then
       ListView1.Items.RemoveAt(i)
    End If
Next i

That problem haunts me, whatever I do it's there.

Thansk, it actually worked

lol! Try this:

For i = 0 To (ListView1.Items.Count -1)

I really can't believe I didn't pick this up the first time around.. I guess I was looking for something a little more complex.

Wouldn't this have been easier, to avoid using an index in the first place:

For Each itm as ListItem In ListView1.Items
   If itm.Text = strName Then
      MsgBox "Matches"
   End If
Next itm

Also, assuming you only want to get the first, and possibly only, match, you can insert in an:
  Exit For
after the MsgBox.

 Thanks, It works without any problemems.

I edited the code so if it finds strName it should delete it because the application-program reads from a text file and adds the the names listed there, but the in the text file the name is referred plenty of times so there's a whole list of the same name, but it won't work, I don't know if it's because there is also included SubItems:


Name            Phone          Email

Christoffer    Nokia        christoffer@something.com

^ that name and with the same subitems is added more than ones because of the text file and I need to delete them but my code won't work:

For i = 0 To (ListView1.Items.Count - 1)
   If ListView1.Items(i).ToString = strName Then
      ListView1.Items.RemoveAt(i)
   End If
Next i

Even simpler still:

I like using the .IndexOf() method.

Dim myItem As New ListViewItem("matchstring")

ListView1.Items.RemoveAt(ListView1.Items.IndexOf(myItem))

I guess I should mention that it isn't good policy to do the above in-line like that, instead get the IndexOf value and check for <> -1 then remove.
