Question

I Declared my Array like this:

Dim invoice_discountitems(100, 1) As String

Now i set values into the array:

invoice_discountitems(0,0) = "test1"
invoice_discountitems(0,1) = "test2"
invoice_discountitems(1,0) = "test3"
invoice_discountitems(1,1) = "test4"

Now I tried to count the elements:

MsgBox(invoice_discountitems.GetLength(0) - 1)

But it display the array size (100,1) I want to display (2) elements

Answer 1

You are displaying the length of the first dimension of the array not the second

MsgBox( invoice_discountitems.GetLength(1) ) '  displays 2 '
