Hi Friend,

Try Out This Code,

Private Sub command1_click()
    Dim Sum, i As Integer
    For i = 0 To List1.ListCount - 1
        Sum = Sum + CInt(List1.List(i))
    MsgBox Sum
End sub
Its always a good idea when calculating sums (or products) to zero the sum before the '' loop, because the subroutine might be called more than once.
Therefore, add
For i = 0 To List1.ListCount - 1
Yes, Absolutelu tsugani is Correct.

But In Vb If We declare as

Dim Sum

It Defaultly Contain the Value Zero
