Yes, I am using HTTP and I'd like to get that 404 response if the file does not exist. My question was how to make this request and how to read the response inside asp.net. In college I learnt application layer protocols and I'd just send the requests to remote server such as SMTP, HTTP and send me responses like 404, 500 or whatever. I just want to do the same thing in ASP.NET.

Use the WebRequest object.
Here is an example, this example though uses POST to send some XML and gets the response as string.
play around with this and see what you get.
HttpWebRequest wrWebRequest = WebRequest.Create(theUrl) as HttpWebRequest;<br />
wrWebRequest.Method = "POST";<br />
wrWebRequest.ContentLength = theXml.Length;<br />
wrWebRequest.ContentType = "text/xml";<br />
<br />
StreamWriter swRequestWriter = new StreamWriter(wrWebRequest.GetRequestStream());<br />
swRequestWriter.Write(theXml);<br />
swRequestWriter.Close();<br />
<br />
HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();<br />
<br />
StreamReader srResponseReader = new StreamReader(hwrWebResponse.GetResponseStream());<br />
responseResult = srResponseReader.ReadToEnd();<br />
srResponseReader.Close();
Hope this helps.

Dear All,
I am working on WSE 2.0 and come around a situation where i need to develop a non WSE client which consumes a WSE 2.0 enabled web service.
My client is a normal aspx page where i am trying to consume the web service through javascript code(xmlhttprequest).
I have developed a SOAP message for the non wse client.
For this i extracted a "request SOAP message" to the same web service from a client which makes use of WSE 2.0.
i copied all this SOAP message as it is in to a client side variable and built the SOAP message for the non wse client.
When i send the request it gives the error that invalid username token.
Can anybody help me regarding this.
Eagerly awaiting

I have a webservice which is uses WSE X.509 standard & is built using .net. Is there any toolkit that enables us to access the web service from C++ client on LINUX?
Thanks a lot!

All of those <Item href...> take up a lot of space, is there a way instruct .net not generate it?
This is the declaration over the webservice C# class file;
[WebService(Namespace=Constants.NAMESPACE), ToolboxItem(false), SoapRpcService]
The web method just has plain, [WebMethod] attribute and that's it.
Thanks,

On our webpage, we have this button:
<asp:Button ID="btnRefresh" runat="server" OnClick="btnRefresh_Click" Text="Refresh" UseSubmitBehavior="False"/>
Here's the code-behind (C#):
protected void btnRefresh_Click(object sender, EventArgs e)
{
Response.Write("<script language=\"javascript\">var confirmResponse = window.confirm('Refreshing. Continue?');</script>");
}
I want to display a confirm dialog (javascript) and have the website do something different based on whether the user clicked OK or Cancel in the confirm dialog box. How do I determine which button the user clicked in the code-behind?

But, this means your page does a postback, THEN generates the confirm dialog.
Wouldn't it be better to have the script already on the page, and confirm before postback ?
The first parameter passed to the event handler is an object, it's called sender. It's the button that was pushed, just cast it to a Control to check it's Id, etc.

F***, I don't know - I'm a c++ programmer - I usually get to deal with REAL user interfaces instead of this 10-pounds-of-crap-stuffed-int-a-five-pound-sack-pseudo-interaction kinda idiocy...

Create an AtiveX control in c++ and use that in your html page.;P

LOL - g'day, John. I didn't spot that it was you.
The easiest way to handle this sort of thing is to add a validator on the page, you can create a custom validator that runs your jscript, and then if the page is not valid, the validator will show, instead of the page posting back.
Oh, to answer your original question, you can't. You'll need to write javascript to show the dialog, and to respond to it. If you're just redirecting to a different page based on the response, you can do that entirely in javascript, and just use an HTML input button, set it's click event to call your method.

With a "real" user interface, you mean a simple client program? I can understand that it's hard to get the hang of how things work when you move on to the more complex client-server model.
The user interface of a client program is so easy. Everything has state, is always available, and everything handles itself. You don't even have to think to program...

After years of writing client software, I found it tough when I started on web apps. So many questions on these forums show that a lot of people ( and I'm not suggesting John is one ) have no idea of what a web app does, in terms of client and server.

Mate if you are a C++ programmer what are you doing with that ASP.net c***. With no offense intended to anyone using the language, it is stupid. PHP (or even a CGI script) means you can actually see what is going on. If you need a bit of help getting started I'll be happy to give you guidance, but within a few months (read days) you will be able to take full advantage of the language. Just email me if you need a hand.
(and now to cover my ass)
ASP.net is very useful if that is the language you have come into web development with. It is certainly unique and a clever way to implement a language  .

Add a client side onclick handler (server side attribute is OnClientClick, the forum changed it to 'removed'):
<asp:Button ID="btnRefresh" runat="server" removed="btnRefresh_Click" Text="Refresh" UseSubmitBehavior="False" OnClientClick="return confirm('Refreshing. Continue?');" />
If the user hits no the confirm function will return false and the button click will be cancelled client-side. Of course if your doing something important in // blah blah blah that might not work (no postback).
You might also want to look at the RegisterClientScriptBlock function rather than using Response.Write

Hi,
I wrote an article about this.
Check it out here..
Custom Javascript Dialog
http://michaelsync.net/2007/01/01/custom-javascript-dialog/
There is one button and a datagrid in that page. If you click "Delete" button then Javascript Popup will be shown. There are two buttons "Delete" and "Cancel" on that popup. If you click "Delete" btn on popup then the records from datagrid will be deleted. you can also cancel by clicking "Cancel" button..
Hope it would help.. Let me know if you have any problem with my article.

Hi,
I want to learn CGI programming. I just need some newbie guidance.
I am using Windows XP Professional, and have installed Apache
successfully.
Can someone please guide me regarding what else do I need to do
to get started with CGI? I've heard that any language can be used
for CGI programming. (C, C++ etc.)
I have downloaded Python and Perl. Can these be used for CGI
programming? and how can I integrate them with Apache for doing
CGI programming? I'm planning to use python, because almost everyone
has told me it's a simple language.
Some light on Apache, CGI, Python and integrating them would be
helpful.
Thanks in advance.

I believe that I'm not getting responses because we are supposed to discuss only Microsoft
Technologies here and not open source.
If that's the case, then I guess I'll have to ask elsewhere.

Mate PHP is a much better way to start of with web languages. If you need guidance in it just send me an email.
|
|

But I've been told that raw CGI with C (or python for that matter) can be
180% percent faster than PHP, and near about 350% faster than ASP.
Then why should I learn PHP just for the sake of programming simplicity?
I agree it's an easy way, but end clients wouldn't care whether it's PHP
or Ruby on Rails doing the work.
For them, it's about speed and reliability. And regarding the aspect of
difficulty: The term 'easy/better language' is bs, if you'll excuse the
expression.
Any language is easy as long as you are playing with ints and designing
nice games of tic-tac-toe. When you want full fledged concurrency control
techniques to handle a pool of persitent connections, or low level control
and deep operating system hooks, it will get complex in any language. Anyone
who argues with that is a moron.
So I might as well start with something which can scale up to millions of
documents and provide blazing fast performance, fast enough to leave ASP, PHP
JSP and the likes eating dust. 
Peace.

The stats you have seen are rubbish. As of PHP 5 it can run just as fast 95% of the time. An example of it in use is Google and YouTube and Flickr, The last two in particular are an excellent example of extremely high load applications in the language.
Not to mention I can code an application in PHP within 200 lines that would take over a thousand in CGI languages. PHP is optimized for power as a server side application, and it's customization allows you to write your own functions that are compiled into the core compiler with little more then 50 lines.
PHP is certainly a major player in the web and is widely accepted for it's incredibly speed and reliability.
