Thread: checking if number in listbox

I have a listbox with phone numbers extracted from a website. but the list is populated with different characters that the program thinks that are potential phone numbers. the phone numbers in the list are in this format: "1231231234" how doI remove all the other items that dont have numberes in them?

Hi,

No idea if this helps, this will totally remove any items that do not evaluate to numbers.

dim lindex as integer

For lindex = (ListBox1.Items.Count -1) to 0 step -1
If Not IsNumeric(ListBox1.Items.Item(lindex)) Then

ListBox1.Items.RemoveAt(lindex)

End If
