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))
Next
MsgBox Sum
End sub
0

Its always a good idea when calculating sums (or products) to zero the sum before the 'for...next' loop, because the subroutine might be called more than once.

sum=0
before
For i = 0 To List1.ListCount - 1
0

But In Vb If We declare as

Dim Sum

It Defaultly Contain the Value Zero
