As far as I know you can't.
So you must register the user somehow, either by logged in session or have some ID as the first question which is then checked against the database before continuing.
Checking the IP-address is not a good solution as there might be several users behind the same NAT-gateway

As Jörgen said, you could use sessions which would do nicely, although it means extra server-side code and processing. You could also use JavaScript cookies, but of course the user can turn these off/delete them which also isn't completely failsafe. If it is really that important, I'd go with the sessions suggestion.

Hi All,
I'm trying to show a PDF document in my webpage hosted in plumtree portal.
The code is executing perfectly but the page is not showing as a PDF rather its showing it as the encoded pdf source.
Following is what is shwon in the webpage "%PDF-1.4 %âãÏÓ 4 0 obj ....."
The code im using is as follows:
MemoryStream ms = new MemoryStream();
//...
ms object will be populated with the pdf data created dynamically.
.....//
Response.ContentType = "application/pdf"; //when i try "text/html" im getting the encoded pdf file in the page like %pdf- ....
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
Response.OutputStream.Flush();
Response.End();
Im using vs2003 C#
Please help me in this issue. This is an urgent requirement.

It's always urgent.
Your chance of getting an answer is increasing if you don't use the word "urgent".
Howabout:
Response.ClearContent()
Response.ClearHeaders()
Response.Buffer = True
Response.ContentType = "application/pdf"
Response.HeaderEncoding = System.Text.Encoding.Default
Response.BinaryWrite(MemoryStream.ToArray)
Response.End()
MemoryStream.Dispose()

Why don't you want the URL to change? This is a fundamental feature of web sites.
|
|
|
|

for my current requirement i should not change the url...
any ideas please...
siri

I would seriously consider changing that requirement - hiding the URL will do nothing other than annoy people using your site and prevent them from bookmarking anything other than the front page. From a personal point of view if I came across a site that tried to do such a thing I'd just not use it.
As someone else has mentioned you can 'fake' it by using frames. Alternatively you could use Flash or some other similar technology. Both would make poor websites with zero advantage.

Its a while since I used them, but I think this can be done with frames (NOT iFrames).

A "dirty" but working solution is to save all html documents with the aspx suffix and exchange all links with linkbuttons having server.transfer(url) in the codebehind
|
|
|
|
|
i mentioned that i' m using html pages not aspx pages.

Hi,
I am connecting via a web service. The response object returns XML data in a string value. How do I get the element values of this string?
Ideally I would like to load it into a dataset but it is not a physical file that I can just read from.
Thanks
Brendan

Hi use this
string message = "<?xml version='1.0' encoding='utf-8'?><Test><Parent><Child1>100354050</Child1><Child2>Jaffer</Child2></Parent></Test>";
DataSet ds = new DataSet();
StringReader sr = new System.IO.StringReader(message);
ds.ReadXml(sr);

Hi everyone, I just built a website by using VB2005 and ASP.NET. I published it and tested the publish version by using VB as back suppourt. The web running well. But when I set to the local server. Login successful, but the button Add / Edit user are always failed, and I changed one user's password, the message shown to it's successful. But when Login again, I still need to use the old password. It seems like the whole database not updated by itself. But once I using VB to view in browser, it can works well. Does anybody can help me to solve this problems??
Thanks a lot

I can run an external java script through browser addressbar to third-party's certain webpage, how can I run script when a page open with no toolbar and addressbar.

FireBug (or FireBug Lite). Google it.
---- You're right.
These facts that you've laid out totally contradict the wild ramblings that I pulled off the back of cornflakes packets .

Hi,
I have a huge product feed, it's about 28MB big. When I try to open it with a web browser then my whole pc hangs. Even with Notepad. Does anyone know of a decent program that I can use to open the large XML file without lettingm y whole PC hang?
And secondly, what is the best way (via C# code) to read this file and to get the values extracted?
Thanks
Brendan

Try a HexEditor, like HexEdit - they are very good at opening large files for reading/writing, although of course you get the hex output on the left side of the page. Might still be worth a try though.
For your second question you might want to try the ASP.NET forum, assuming you are writing your program for this.

You seem to be creating a HTML table, pretending it's a PDF file, and then hoping the browser can handle all the minor complications of converting it to a real PDF file?

please give me the solution.

Try this [^], it should give you all the information you need.

You cannot convert HTML to PDF by simply saying that it's a PDF file. I'd suggest taking some time to investigate exactly what HTML and PDF are, why they are different, and how you would use a server-based solution to convert from one to the other. As someone else has suggested, Google will undoubtedly be your friend here.
