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?

For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?

My problem though is that the file has one field at the end that I don't want to display. I'm not sure though how to not to add it as a DataRow or what to do so that it won't be displayed. Do you know what I might do. This is my

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.

How do I remove an item from an array at a specified index? This code copy's the index and then adds the indexes until it gets to the one you want to remove, skip it, and try to continue. But I get so many errors. From being out of the bounds of the array, to just being null for some odd reason. [Code]
