[RESOLVED] [2008] Changing ListView items on one form from another form

Ok, basically, what I tried to do is:
I have two forms, the app's main form and a second form.
When a particular event happens on the second form, I want to change an item in a ListView on the main form.
Since events cannot be raised from another class, I created a Public Sub in the main form with all the necessary code to change the ListViewItem in the ListView. I then call the sub from a background worker thread of the second form, with all the neccessary Invokes and stuff.

Now, to the problem:
The sub accesses the ListView in its own class, but refuses to view any of its items or the Items.Count property, and is therefore useless.

Why is this happening and how do I solve it? Also, if there is another, better way of doing this, please tell me. Thx:wave:

its probably because of the different thread.
use a delegate sub:

vb Code:

Private Delegate Sub change_listview_Callback()
 
Private Sub change_listview()
    If listview1.InvokeRequired Then
        listview1.Invoke(New change_listview_Callback(AddressOf change_listview))
    Else
        ''put your code from your sub here
    End If
End Sub

I am already using a delegate sub, so that's not the answer. Here's the actual code, if that's any help:

vb.net Code:

Private Delegate Function ItemFoundInListInvoker(ByVal oldname As String, _
                                                     ByVal name As String, _
                                                     ByVal changes As Boolean) As Boolean
 
Private Function ItemFoundInList(ByVal oldname As String, _
                                     ByVal name As String, _
                                     ByVal changes As Boolean) As Boolean
        If Me.ListView1.InvokeRequired Then
            Me.ListView1.Invoke(New ItemFoundInListInvoker(AddressOf ItemFoundInList), oldname, name, changes)
        Else
            Dim index, itemsCnt As Integer
            index = -1
            itemsCnt = Me.ListView1.Items.Count - 1
            For i As Integer = 0 To itemsCnt
                If Me.ListView1.Items.Item(i).SubItems(3).Text = oldname Then
                    index = i
                    Exit For
                End If
            Next
            If index = -1 Then
                Return False
            Else
                If changes Then
                    Me.ImageList1.Images.Add(Icon.ExtractAssociatedIcon(name))
                    Me.ListView1.Items.Item(index).ImageIndex = ImageList1.Images.Count - 1
                    Me.ListView1.Items.Item(index).Text = name
                    Me.ListView1.Items.Item(index).SubItems.Item(1).Text = GetFileType(name)
                    Me.ListView1.Items.Item(index).SubItems.Item(3).Text = name
                End If
                Return True
            End If
        End If
    End Function

Oh come on! Somebody please HELP! I'm getting desperate ;)

Never mind, problem SOLVED!
