Find In List / Remove Item And Ignore Case Of Characters In String

May 20, 2012

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.

The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)

Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))

If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?

Remove A Context Menu Item?

May 21, 2009

how to delete a item from the context menu.. i can add a item with this code:

Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click
ContextMenuStrip4.Items.Add("delete file")
End Sub

no problem there. and to delete this item, i figured since it is the 4th item in the contextmenu (and i can't type the "delete file" either w/o error) it would delete it by index, with this code:

Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
ContextMenuStrip4.Items.Remove(3)
End Sub

the (3) is giving me a error "value of type 'interger' cannot be converted to 'system.windows.forms.toolstripmenu'".. i think that means that the context menu does not support indexing.
