Why the value inside array becomes empty? [Resolved]

[albertlse]

This is the code i work out:

Private Function funSplitText(ByVal strRinggit As String) As String()
        Dim strSplitted() As String = System.Text.RegularExpressions.Regex.Split(strRinggit, " ")

        Dim strConcatenatted() As String
        Dim strConcatenattedSize As Integer = 0
        ReDim strConcatenatted(strConcatenattedSize)

        Dim strTemp1 As String
        Dim strTemp2 As String

        Dim intCounter As Integer
        For intCounter = 0 To strSplitted.GetUpperBound(0)
            strTemp1 = strTemp1 & String.Concat(" ", strSplitted(intCounter), " ")
            strTemp1 = strTemp1.TrimStart(" ")
            strTemp1 = strTemp1.TrimEnd(" ")

            strTemp2 = strSplitted(intCounter)

            If strTemp1.Length > 39 Then
                strConcatenattedSize += 1
                ReDim strConcatenatted(strConcatenattedSize)
                strConcatenatted(strConcatenattedSize) = strTemp2
                strTemp1 = strTemp2
            Else
                strConcatenatted(strConcatenattedSize) = strTemp1
            End If
            'MessageBox.Show(strConcatenattedSize & ": " & strConcatenatted(strConcatenattedSize))
        Next

        Dim x As Integer
        For x = 0 To strConcatenatted.GetUpperBound(0)
            MessageBox.Show(x & ": " & strConcatenatted(x))
        Next

        Return strConcatenatted
    End Function

When i use the last MessageBox to display all value inside the array (strConcatenatted), i found that the array are all empty except the last array, which has value on it.
For example, strConcatenatted's length is 3
the value on:
strConcatenatted(0) is ""
strConcatenatted(1) is ""
strConcatenatted(2) is "abcde"
actually all of them should has string value.

why is this so weird? pls guide me, thank you.

Not sure but doesn´t the Redim empty the whole array?
Try and set it to 3 and run it 3 times?

Yes, if ReDim isn't accompanied by the Preserve keyword, the array will empty
