Listbox Item Exist Validation......ignore Case?

Feb 14, 2009

I have written the code below to check and see if the text the user entered into the txtbox already exists as an item in a listbox before adding the new item. This works well; however, if say "Fish" exists in the listbox but the user entered "fish" in the textbox, the item is added to the listbox. I do not want this because the item already exists. How can I modify my code so that the comparison is not case sensitive?

'Check to make sure the active medication does not already exists in the list
If lstActiveMeds.Items.Contains(strActiveMeds) = True Then
MessageBox.Show("The active medication you entered has already been added to the list.",

[code].....

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?

VS 2010 Remove From Listbox If It Doesn't Exist?

Mar 7, 2011

What i need is, if a item in a listbox Doesn't exist, it needs to remove it from the other.

In the pic i have attached. Basically If it doesn't exist in Listbox2 then it needs to be removed from Listbox1 and tell the user which one has been removed.

i.e Test 02 doesn't exist. So messagebox would show "test02 has been removed" then remove it from listbox 1

It probably something simple thats sitting in the back of my mind, but for the life of me can't figure it out lol
