Now find the control string from the object, inspect renderedoutput.

Why not just pass it on the URL ?

Where do you store them ?

What are you writing this for ? Is it for your own study ? Will it ever be used by anyone ?

im storing in sql server.
this is used for my project...

OK, so you're writing it for yourself, or for someone to use ?
Why not just pass the id of the image back to the main page then and load it from there ?

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.
madhukk wrote: passed id to imageurl of image using session...
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.

can we display the thumbnail of image before inserting into database....
|
|

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: 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,
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,
