Vb2010 Listbox question

[bheilig]

ok so i am using vb2010 and I have created two listboxes and a textbox and a button. the first list box has a my list in it like seen below:

U-Ad ($350)
Striker ($190)
New Ad ($250)
Samson ($530)

as you select one of these list items in the first box and click the button it adds that item to the second listbox. Then the textbox is being used to add the monetary value of the items to a total of the ones you have selected. textbox updates as you add more from the first listbox to the second. I cannot figure out what code to write to have the values add up in the textbox? any help?

Try this

Public Class Form1

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        ListBox1.Items.Add("U-Ad ($350)")
        ListBox1.Items.Add("Striker ($190)")
        ListBox1.Items.Add("New Ad ($250)")
        ListBox1.Items.Add("Samson ($530)")
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim v As Decimal

        ListBox2.Items.Add(ListBox1.SelectedItem)
        Decimal.TryParse(TextBox1.Text, v)

        v += GetMoney(ListBox1.SelectedItem)
        TextBox1.Text = v.ToString
    End Sub

    Private Function GetMoney(ByVal strValue As String) As Decimal
        Dim a As Integer = strValue.IndexOf("($")
        Dim b As Integer = strValue.IndexOf(")")
        Dim v As String = strValue.Substring(a + 2, b - a - 2)
        Dim r As Decimal

        Decimal.TryParse(v, r)

        Return r
    End Function
End Class
