This is the output after amended as per your suggestion. those zeros are coming from the variable inside the loop after reading the datagridview. second one is string that is why it is blank

i want to eliminate the zeros only the first 4 things should come. thanks

You do not need to declare your temporary variables as an array - replace:

VB

Dim qty(100) As Double
Dim price(100) As Double
Dim total(100) As Double

with

VB

Dim qty As Double
Dim price As Double
Dim total As Double

and assign the variables each time you go round the loop:-

VB

itemcode = DataGridView1.Rows(i).Cells(0).Value
price = DataGridView1.Rows(i).Cells(2).Value
qty = DataGridView1.Rows(i).Cells(1).Value                       
total = DataGridView1.Rows(i).Cells(3).Value

Also - don't use MsgBox for debugging - use System.Diagnostics.Debug.Print and breakpoint on that row.
