I have create a shopping cart in vb.net, so far i can add items to cart but cant empty or remove items from cart. this is the code I have so far:-
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
<div id="mycart">
<br />
[code]....
Note: This code actually codes from a tutorial book I'm reading at the moment, so you can imagine this is frustrating me greatly! I'm building a basic shopping cart, using VB.NET 4, Visual Studio 2010 and MS SQL Server R2 2008. The code below is supposed to remove items from the cart, by reading a session variable, editing it to remove the appropriate ProductID and return the amending string to the session variable. It is then supposed to rebind the data to the gridview (gvCart) to refresh the data...but it seems here there is an error.
Every time I build the site in Visual Studio, it validates fine. But every time I run the site, and attempt to use the remove button it gives me the error:Incorrect syntax near ')'.ith the IDE pointing me toward the final parenthesis
Protected Sub gvCart_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles gvCart.SelectedIndexChanged
'This method is hooked to the Remove button & is removing items from the cart
[code].....
i am developing an online shopping site..so when the user adds any item to the cart i store it in a table...now what i want is to count the number of items in the cart as well as update the number of items in cart every time the user adds a new item....
Public Function AddToCart(ByVal itemID As String, ByVal itemName As String, ByVal itemPrice As Integer, _
ByVal offer As String, ByVal buyNo As String, ByVal userID As String) As String
Dim sqlStatement As String = "INSERT INTO shoppingCart" & _
[code].....
How can I get the items in my code from my listbox which is called "selectListBox" to a shopping cart called "cartlistbox", when the add button is clicked?
Public Class MainForm
Private Sub MainForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

i have a listview box full of items, image below:
when i click a button i would like a msgbox to pop up displaying how many are alive.
How would i do this ?
Also how would i remove all items that status is "Dead"
Imports System.Collections.GenericI
mports System.Net
Imports System.IO
Public Class Form2
'Dim filename As String
Public ftpSettings As FtpClient
[Code]...
I don't know what's wrong, i can only move the 1st item but the second and so on doesn't make any changes. It remains in a listbox.
So I want it to remove any text in the list box that has a "Job" in it and just replace it with a blank nothing.
Like if the listbox looked like this
Yardjob
jobsong
redjob
then it would change it to this
Yard
song
red
I also would like a way of removing any blank items from the listbox.

View 10 RepliesI have a serious problem, I have 3 listboxes, and all three of them will get items that contain no text. My problem is that I have the same code for all three listboxes to remove "" from the listboxes except one listbox will not remove the items. I've tried countless times to remove the empty items and failed. So how do you see if a listbox's item contains no text?
