Hi, I'm messing around with a listview in VB.NET and I'm having a problem with declaring an array of ListViewItems.
Here is what I have so far:
'Test function for populating information in a listview
Private Sub LoadList(ByVal ListView1 As ListView, ByVal dsRecord As ADODB.Recordset)
Dim listitem1() As ListViewItem
Dim ctri As Integer
ListView1.BeginUpdate()
ListView1.Clear()
ListView1.Columns.Insert(0, "String", 100, HorizontalAlignment.Left)
ListView1.Columns.Add("Test", 100, HorizontalAlignment.Left)
ListView1.Columns.Add("Test2", 100, HorizontalAlignment.Left)
ListView1.Columns.Add("Test3", 100, HorizontalAlignment.Left)
ListView1.Columns.Add("Test4", 100, HorizontalAlignment.Left)
For ctri = 0 To 9
listitem1(ctri) = New ListViewItem() 'This line generates the error
listitem1(ctri).SubItems.Add("subitem" & ctri)
listitem1(ctri).SubItems.Add("subitem" & ctri)
listitem1(ctri).SubItems.Add("subitem" & ctri)
ListView1.Items.Add(listitem1(ctri))
Next ctri
ListView1.EndUpdate()
End Sub
This is the error it generates:
An unhandled exception of type 'System.NullReferenceException' occurred in WindowsApplication6.exe
Additional information: Object reference not set to an instance of an object.
Can anyone here show me the correct way of coding an array of an unknown size and using it to populate my listview?
Thanks
