newbie qestion

Here is an example of some code that I am working on, it is a very basic example:

Dim test1(8) As Integer
Dim test2(8) As Integer
Dim a As Integer
dim j As Integer

test1(1) = 1
test1(2) = 2
test1(3) = 1
test1(4) = 3
test1(5) = 8
test1(6) = 2
test1(7) = 8
test1(8) = 3

For j = 1 To 8
a = test1(j)
test2(j) = a
Next j
End Sub

This is my dillema
How can I add to the second array the values in the first array, here is the tricky part. I do not want duplicates.
so at the end the second array will have the values: 1, 2, 8 and 3. (I know I will have empty slots in the array, but I just want see all the values withough duplicates) Can this be done, thanks

You can do something like this:

Code:

---

Private Function HasDuplicates(pArr() As Integer, pValue As Integer) As Boolean
    Dim i As Integer
   
    On Error GoTo ErrHnd
   
    For i = LBound(pArr) To UBound(pArr)
        If pArr(i) = pValue Then
            HasDuplicates = True
            Exit Function
        End If
    Next
   
    Exit Function
   
ErrHnd:
    'Don't do anything here, the function will return False
End Function


Private Sub Command1_Click()
    Dim arrOne(1 To 8) As Integer
    Dim arrTwo() As Integer
    Dim i As Integer
    Dim intIndex As Integer
   
    arrOne(1) = 1
    arrOne(2) = 2
    arrOne(3) = 1
    arrOne(4) = 3
    arrOne(5) = 8
    arrOne(6) = 2
    arrOne(7) = 8
    arrOne(8) = 3

    On Error Resume Next
   
    For i = LBound(arrOne) To UBound(arrOne)
        If Not HasDuplicates(arrTwo, arrOne(i)) Then
            ReDim Preserve arrTwo(intIndex)
            arrTwo(intIndex) = arrOne(i)
            intIndex = intIndex + 1
        End If
    Next
End Sub

---

Also, pay attention how I declared the array (arrOne(1 To 8)). This way you can use the way you did.

Dim test1(8) As Integer
Dim test2(8) As Integer
Dim a As Integer
dim j As Integer, i as Integer
Dim bolFound as Boolean
Dim intTest2Counter as Integer

test1(1) = 1
test1(2) = 2
test1(3) = 1
test1(4) = 3
test1(5) = 8
test1(6) = 2
test1(7) = 8
test1(8) = 3

intTest2Counter = 0
For j = 1 To 8
bolFound = False
for i = 1 to 8
if test2(i) = test1(j) then
bolFound = True
exit for
end if
next i
if not found then
test2(intTest2Counter) = test1(j)
intTest2Counter = intTest2Counter + 1
end if
Next j
End Sub

He he he.....Steel has my signature.....that is so funny...lol

You can add the code I put in the For loop. This will create a stringand search the string for the exsistence of your previous number. You still need to follow Serge's suggestions about your Dim. Also you could run into limitations of the text string if you are using a large array.

Code:

---

    Dim test1(8) As Integer
    Dim test2(8) As Integer
    Dim A As Integer
    Dim j As Integer

    Dim strTemp As String

    test1(1) = 1
    test1(2) = 2
    test1(3) = 1
    test1(4) = 3
    test1(5) = 8
    test1(6) = 2
    test1(7) = 8
    test1(8) = 3

    For j = 1 To 8
        If InStr(1, strTemp, "'" & test1(j) & "',", vbBinaryCompare) = 0 Then
            strTemp = strTemp & "'" & test1(j) & "',"
            test2(j) = test1(j)
        End If
    Next j

    MsgBox strTemp
