Putting a datatable into the session seems wasteful to me.
KhandelwalA wrote: For i As Integer = 0 To DataList1.Items.Count - 1
Does this work ? In C# it would miss the last item.
KhandelwalA wrote: Session("Cart") = dt
Every time ? Why on earth are you doing this inside the loop ?
KhandelwalA wrote: DataList1.DataSource = dt
DataList1.DataBind()
Wow - again, this is very wasteful.
KhandelwalA wrote: is there any other way to do it.........
There's much better ways to do this. How about storing an id in the session and storing the cart in the database ? Then you could modify the cart with SQL, for a start.
KhandelwalA wrote: Dim txt As Integer = CType(DataList1.Items(i).FindControl("txtQty"), TextBox).Text
KhandelwalA wrote: Dim val As Integer = Convert.ToInt32(txt)
What are you writing this for ? Is it actually going to be used for anything ? By whom ?

Hi,
Need a regular expression for Password Policy Validation...
The Password Policy should allow the contents mentioned below.
1. Password should be minimum of 9 characters in length
2. It should contain four characters [choose from a-z, A-Z]
3. It should contain four digits [choose from 0-9]
4. It should contain exactly one special character
[choose from #, @, $, !, underscore( _ ), hyphen (-), dot(.)]
Examples of correct passwords:

hi,
I need to implement search query in asp web form using c-sharp. I have taken a textbox control "txtSearch" and want to have search query through Google search engine.
|
|
|
|
|
|
no..its not like that i wanted
in web form , i've taken one textbox "txtSearch" and one button "btnSearch"..
When anyone searches some text by writing text to be searched in the txtSearch , then by clicking on the btnSearch ,it must automatically directs to google search.
|
|
|
|
|
What have you tried ? Just doing a couple of google searches should tell you the syntax to redirect to google with a search query. What is the problem ?

Hello all,
I have an asp.net page uploading a file to D driver. It works well with ASP.NET server.
<br />
protected void Button6_Click(object sender, EventArgs e)<br />
{<br />
FileUpload1.SaveAs("D:\\a.txt");<br />
}<br />
when I published (to IIS) and ran it from IE, it caused an error: Access to the path 'D:\a.txt' is denied as following.
<br />
[UnauthorizedAccessException: Access to the path 'D:\a.txt' is denied.]<br />
System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) +651<br />

<br />
Best regards,
P/S:
The code for this problem is here:
I have an ASP.NET and this is the code in default.aspx:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button6" runat="server" önclick="Button6_Click" Text="Button" />
<br />
<br />
</form>
</body>
</html>
And here is the code into default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs("D:\\a.txt");
}
After compiling the project, I published it as following:
clicked right mouse on it and selected "Publish Website". Then I copy published files to a folder example (a subfolder of C:\Inetpub\wwwroot). Finally, I ran IE and fill in the address: http://localhost/example/default.aspx, clicked button_6, and got the error.
I installed IIS on my local computer with version v5.1
Thanks,

Does D: Drive exist on your server? Is it writeable, or is it a CD Drive? Do you have permissions to write to the root of D: Drive? Does your IIS process user have permissions to write to the root of D: Drive?
|
|
|
|
|
Yes, D: Local Drive exists on my computer.
I do not know whether I have permissions to write or not, but when I run the page using ASP.NET Server, It works well. After I published and then used IIS Server, It threw the error.
I do not know how to check permissions both the root of D: Drive and IIS process, and I need your help.
Thanks,

Your computer is the server ?

A website should not have permission to read or write above the application root, so even if you have a D drive on your server, I'd expect this not to work.

No, D: is my Local Drive and my computer is not a server. I have that project on my personal computer.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button6" runat="server" onclick="Button6_Click" Text="Button" />
<br />
<br />
</form>
</body>
</html>
And then I have an event to fileUpload1 Control:
protected void Button6_Click(object sender, EventArgs e)
{
FileUpload1.SaveAs("D:\\a.txt");
}
I ran the project from virtual server of ASP.NET, it worked well.
But when I published it to IIS server, it threw that error.
Thanks,

So your computer IS where IIS is running, and therefore is the server, right ?

Published it how ? Is IIS running on your local machine ?

Yes, I installed IIS into Windows XP on my personal computer.

Yes, IIS is running on my local machine. After creating a ASP.NET project in Visual Studio 2008 and writing code as I mentioned above, then I compiled the project, clicked right mouse on it and selected "Publish Website". Then I copy published files to a folder example (a subfolder of C:\Inetpub\wwwroot). Finally, I ran IE and fill in the address: http://localhost/example/default.aspx, clicked button_6, and got the error.
