How to create an Excel Groups and Subtotals

Hi all,

From within:
With wkbApp
End with

I am trying to create an Excel report using the Tools, Subtotal options to create subtotals in three columns, grouping on one column using the following code. The code was recorded in the Excel macros and copied to VB.net -

.Selection.Subtotal GroupBy:=6, Function:=xlSum, TotalList:=Array(7, 8, 9, 10), Replace:=True, PageBreaks:=False, SummaryBelowData:=True
By itself, the code fails because the array is not defined.  

I then tried :
Dim myArray As Array = Array.CreateInstance(GetType(Excel.XlRowCol), 1)
.Selection.Subtotal(GroupBy:=6, Function:=10, TotalList:=myArray(7), _
            Replace:=True, PageBreaks:=False, SummaryBelowData:=True)
The error for this is System.IndexOutOfRangeException:  Index was outside the bounds of the array.

AND

Dim myArray As Array = Array.CreateInstance(GetType(Excel.XlRowCol), 4)
.Selection.Subtotal(GroupBy:=6, Function:=10, TotalList:=myArray(7, 8, 9, 10), _
            Replace:=True, PageBreaks:=False, SummaryBelowData:=True)
Each time I receive
System.RankException: Attempted to operate on an array with the incorrect number of dimensions.

Can anyone help with the correct code to perform this task?

Thanks

How many dimensions does MyArray have?  

What type of array are you trying to pass?  I think that you meant to create an array like this:

Dim myArray As Integer() = {7, 8, 9, 10)

.Selection.Subtotal(GroupBy:=6, Function:=10, TotalList:=myArray, _
            Replace:=True, PageBreaks:=False, SummaryBelowData:=True)
