where is @ for the img_stream ? When your debugger showing the error , then click on the error, debugger redirect you to the correct line.

Hello........I m decveloping an application in which i hav to create data table dynamically......i hav written the code the but getting the error....plz help me...code is below:-
Dim objDT As New System.Data.DataTable
Dim objDR As System.Data.DataRow
Private Sub Page_Load(ByVal s As Object, ByVal e As EventArgs)
If Not IsPostBack Then
makeCart()
End If
End Sub
Function makeCart()
objDT = New System.Data.DataTable("Cart")
objDT.Columns.Add("ID", GetType(Integer))
objDT.Columns("ID").AutoIncrement = True
objDT.Columns("ID").AutoIncrementSeed = 1
objDT.Columns.Add("Quantity", GetType(Integer))
objDT.Columns.Add("Product", GetType(String))
objDT.Columns.Add("Cost", GetType(Decimal))
Session("Cart") = objDT
End Function
Sub Delete_Item(ByVal s As Object, ByVal e As DataGridCommandEventArgs)
objDT = Session("Cart")
objDT.Rows(e.Item.ItemIndex).Delete()
Session("Cart") = objDT
dg.DataSource = objDT
dg.DataBind()
lblTotal.Text = "$" & GetItemTotal()
End Sub
Sub AddToCart(ByVal s As Object, ByVal e As EventArgs)
objDT = Session("Cart")
Dim Product = ddlProducts.SelectedItem.Text
objDR = objDT.NewRow(GETTING ERROR IN THIS LINE)
'Error is same which is written in Subject line
objDR("Quantity") = txtQuantity.Text
objDR("Product") = ddlProducts.SelectedItem.Text
objDR("Cost") = Decimal.Parse(ddlProducts.SelectedItem.Value)
objDT.Rows.Add(objDR)
Session("Cart") = objDT
dg.DataSource = objDT
dg.DataBind()
Dim blnMatch As Boolean = False
For Each Me.objDR In objDT.Rows
If objDR("Product") = Product Then
objDR("Quantity") += txtQuantity.Text
blnMatch = True
Exit For
End If
Next
If Not blnMatch Then
objDR = objDT.NewRow
objDR("Quantity") = Int32.Parse(txtQuantity.Text)
objDR("Product") = ddlProducts.SelectedItem.Text
objDR("Cost") = Decimal.Parse(ddlProducts.SelectedItem.Value)
objDT.Rows.Add(objDR)
End If
lblTotal.Text = "$" & GetItemTotal()
End Sub
Function GetItemTotal() As Decimal
Dim intCounter As Integer
Dim decRunningTotal As Decimal
For intCounter = 0 To objDT.Rows.Count - -1
objDR = objDT.Rows(intCounter)
decRunningTotal += (objDR("Cost") * objDR("Quantity"))
Next
Return decRunningTotal
End Function
</script>

I suspect that objDT is null. Have you stepped through the code, to see if this is so ? How about writing code that checks for nulls and doesn't blow up ?

Why don't use "Session("Cart")" variable which already stored the data table. objDT is returning null. Typecast the session variable into a datatable object.
There is no foolish question, there is no final answer...

Did you check the Session variable for null ?
Where is the Type Cast ?

So that the reason that you are getting error here.

Hi Everybody
I need to fetch most visited articles from my News module...Please give me some idea
Thanks in advance

What have you tried ? What seems the obvious way to do that ? Do you store a counter for how often a page is visited ? If not, how do you expect to do this ? If so, it suddenly becomes trivial, right ?

How are you going to track that totally depends on your strategy and business requirement? But stating from the basic, you can probably create a column called "viewcount" on any of the table where you are storing all articles. In the page load and under if(!IsPostBack) just write down the code to update the "viewcount" flag by 1. Just a basic idea which may help you.

You could always use something like Google Analytics - It takes a few minutes to set up as it just requires that you add some javascript to your page.
Alternatively, you probably want to create a database table and each time you have to render a news article INSERT a row in the database to say what article was rendered and any other information you want to store with that (e.g. a date/time, the UrlReferrer, etc. etc.)
To get the most visited articles all you need to do is count each time an article appears in the database.

Hi all,
I want to redirect the page after alert box is clicked . but the page redirects before the alert was called Wat to do..
|
|
|
|
|
can you paste the code that is redirecting the page and displaying alert
|
|
|
|
|
You should use javascript,fire function name from your control.
function ShowAlert()
{
alert('You will redirect in another page');
window.open(' yoururladdress/pagename.aspx');
}
onclick="ShowAlert()"

This is wat i used but the page is redirected without waiting for alert box.
|
|
|
|
|
Which control you are using to redirect in another page?
If you are using button then use property
OnClientClick="ShowAlert(); return false;"

Your core problem is that you think we're mind readers. Your code is broken. We can't fix it without seeing it.

This is the code at client side
function changed() {
alert('Password changed successfully');
window.open("UserProfile.aspx");
return false;
}
I called it at the server side as
Page.RegisterStartupScript("Error", "<script>changed()</script>");
Response.Redirect("UserProfile.aspx");
inside the click event of the button.That button will cause validation also.
My problem is the page is redirected before alert is clicked.

According to me, the code should redirect to Default.aspx not UserProfile.aspx.
In server side code, you register the client script block and then you redirected it to Default.aspx. You comment the Response.Redirect, it will start redirecting to UserProfile Page
|
|
|
|
|
Yes, that's always going to be the case - why don't you put your redirection into the javascript function as well...

This injects script into the page.
anu_anu wrote: Response.Redirect("UserProfile.aspx");
This redirects, so that your page is never rendered.

Post the code which you are using. Code shared by Blue Boy should definitely work.

What makes you think that an assembly of that name exists ?
