I have a strucutre in vb.net whose each element is a numeric variable, for example:
dim strTotals as structure
   dim total1 as decimal
   dim total2 as decimal
   dim total3 as decimal
  .....
end Structure

dim vtotals as strTotals

I want to assign 0 to each element in one single instruction. Is any way to do that or Do I have to assign 0 in this way: vtotal.total1=0: vtotal.total2=0: ....?

thanks in advance

I can't think of any way other than perhaps using reflection to loop through structure elements which could be more work.

First, your structure declaration looks like VB-Sharp. VB syntax should be
    Private Structure strTotals
        Dim total1 As Decimal
        Dim total2 As Decimal
        Dim total3 As Decimal
    End Structure

Open in new window

Second, in VB you don't need initialize integers (as well as double, float, decimal and other numerics) with 0 - they are zero by default:
  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim vtotals As strTotals
        MsgBox(vtotals.total1) 'show 0
    End Sub

Open in new window

If you need init structure with values other then 0, you can either use New method:
    Private Structure strTotals
        Dim total1 As Decimal
        Dim total2 As Decimal
        Dim total3 As Decimal
        Public Sub New(ByVal t1 As Decimal, ByVal t2 As Decimal, ByVal t3 As Decimal)
            total1 = t1 : total2 = t2 : total3 = t3
        End Sub
    End Structure
'.....
Dim vtotals As New strTotals(1, 2, 3)

Open in new window

or with VS2010 use With keyword:
Dim vtotals As New strTotals With {.total1 = 1, .total2 = 2, .total3 = 3}

Open in new window
