The image is associated with the user, right ? So, just write a http handler that takes the id of the image or the user on the query string, looks up the data and returns it. Make this the URL for your image.

I'm not sure why you're asking me for advice, as you appear to, in every step, doing the opposite of what I've suggested. Filling your session with all this data is going to affect performance.

Why would you want to ? What is it that you're trying to do ? If you'd answer this question it might help me make a recommendation.

i want to display the uploaded image once i browse through fileupload control.. but before it is saved in database to check the image uploaded correctly or not..

You can't do that, because until it exists somewhere on your system, you can't send it back to the client. To send it back as a byte stream requires a seperate page or HTTP handler. It's just not possible.

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:

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:
wxyz$6789 or a1b2#c3d4

Please help and Suggestions are welcomed.

Thanks in advance.

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 />
   System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) +1038<br />

   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1746<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 ?
