Dim myTable As DataTable = myDs.Tables(0)
Dim myRow As DataRow
' check myTable first
If myTable.Rows.Count >= Index Then
 myRow = myTable.Rows(Index)
End If
Dim row As DataRow = myTable.NewRow()

If myTable.Rows.Count >= Index Then
 myRow = myTable.Rows(Index)
End If
Why does this happen?

I don't know what is Index variable values. Can you show me entire your code (declare Index and assign it value).

I need to check the index of row because maybe your table have number of row less than the value of Index

Here it is.
Private dbManager As Database = DatabaseFactory.CreateDatabase("DevConfigServer")

        Public Function IncrementDate(ByVal DtPeriod As String, ByVal IncrementAmount As Integer) As String
            Dim strResults As String
            Dim intYear As Integer
            Dim intMonth As Integer
            intYear = Int32.Parse(DtPeriod.Substring(0, 4))
            intMonth = Int32.Parse(DtPeriod.Substring(4, 2))
            intMonth += IncrementAmount
            If intMonth > 12 Then
                intYear += 1
                intMonth -= 12
            End If
            strResults = intYear.ToString & intMonth.ToString().PadLeft(2, "0")
            'strResults = intYear.ToString & intMonth.ToString
            Return strResults
        End Function




Public Function GetBusinessCalendarPeriod(ByVal dbName As String, ByVal DatePeriod As String, ByVal txtMaxPeriod As String) As DataTable

Dim retVal As New DataTable("BusinessCalendars")

Dim DtPeriod As String = DatePeriod

Dim MaxPeriod As Integer = Int32.Parse(txtMaxPeriod)

Dim cmd As DbCommand

Dim tmpds As DataSet = New DataSet()

Dim StoredProcName As String = String.Empty

Dim DateIndex As Integer

'We get the divisions

For Index As Integer = 0 To MaxPeriod - 1

' Get date period

StoredProcName = dbName & ".dbo.usp_GetDatePeriodFromTo"

cmd = dbManager.GetStoredProcCommand(StoredProcName)

dbManager.AddInParameter(cmd, "@YEARMONTH", DbType.String, DtPeriod)

DtPeriod = IncrementDate(DtPeriod, DateIndex)

DateIndex = Index + 1

' Put the yearmonth, start date ,and end date in a dataset

Dim myDs As DataSet = dbManager.ExecuteDataSet(cmd)

Dim myTable As DataTable = myDs.Tables(0)

Dim myRow As DataRow = myTable.Rows(Index)  <===========

Dim row As DataRow = myTable.NewRow()

row.ItemArray = myRow.ItemArray

Next

Return retVal

End Function
