I’m having some trouble with my array list. I’m using my array list to store numbers in it. Adding stuff to it works fine. But searching the array list to see if it already contains a number is proving more difficult. Here’s what I’ve got: Code: Public Sub TestNum() Dim p As String Dim q As String = frm_EnterInfo.TextBox1.Text For Each p In c_TestArrayClass.NumArray If p = q Then frm_enterInfo.Label3.Text = "Found in Array" Exit For Else frm_enterInfo.Label3.Text = "Not Found" End If Next End Sub I get this error when I run it "Conversion from type 'EnterInfoClass' to type 'String' is not valid" and it points to this part: Code: For Each p In c_TestArrayClass.NumArray Could anyone help me?
