Duplicate entried in array

How do i compare a 9 digit number with all the rest of the elements in an array.


I used a for...next loop to extract the .Substring(0,8)elements....now i want to produce an msg box if one is duplicated

Hi Kyle

Use sorting and then doing loop :
for idx = lbound(MyArr) + 1 to MyArr.length
if MyArr(idx) = MyArr(Idx-1) then
msgBox bla...bla...bla...
end if
next

regards...

vb Code:

For index = LBound(Array) + 1 To Array.Length
            If Array(index) = (Array(index - 1)) Then
                MsgBox("Error")
                End
            End If

that was my code......

vb Code:

81908608    66
88884648    24
395880576   59
945064256   62
551614528   0
755506560   88
132684352   38

and that is the array it is searching....why does it give me an rror every time....i want code to compare the array.substring(0,8) *the first 9 numbers in each line* and if = TextBox1.Text....i want TextBox2.Text to equal array.substring(9,2) *the last two digits*
