There isn't a built-in function for a "token" split... so you'll have to write one!

Here is a good starting point... you might consider adding a bit of error checking, etc

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim i As Integer
        Dim parts() As String

        parts = TokenSplit("Part1:*-*:Part2", ":*-*:")
        For i = 0 To UBound(parts)
            Debug.WriteLine(i & ", " & parts(i))
    End Sub

    Function TokenSplit(ByVal str As String, ByVal token As String) As String()
        Dim ans(10) As String
        Dim ans_count, t_len, marker, prev As Integer

        t_len = token.Length

        ans_count = 0
        prev = 0
        marker = 0
        Do While marker >= 0
            ' find the index for the start of the token
            marker = str.IndexOf(token, marker)
            If marker > 0 Then
                ' copy the substring into our answer array
                ans(ans_count) = str.Substring(prev, marker - prev)
                ans_count += 1
                ' redim in chunks of 10
                If ans_count > UBound(ans) Then
                    ReDim Preserve ans(UBound(ans) + 10)
                End If
                prev = marker
                marker += t_len
            End If

        ' don't forget the stuff past the last token
        If prev + t_len < str.Length Then
            ans(ans_count) = str.Substring(prev + t_len)
            ans_count += 1
        End If

        ' special conditions (no token at all)
        If ans_count = 0 Then
            ans_count = 1
            ans(0) = str
        End If

        ReDim Preserve ans(ans_count - 1)
        Return ans
    End Function

grave, it looks like hailkle's suggestion does the trick just fine
Humph... you're right.   The documentation says "a single character" as the delimiter, but obviously a multi-character string works too
