C# - Read Specific Div From HttpResponse?
Feb 22, 2011I am sending 1 httpWebRequest and reading the response. I am getting full page in the response. I want to get 1 div which is names ad Rate from the response. So how can I match that pattern?
My code is like:
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create("http://www.domain.com/");
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
Stream response = WebResp.GetResponseStream();
StreamReader data = new StreamReader(response);
string result = data.ReadToEnd();
I am getting response like:
<HTML><BODY><div id="rate">Todays rate 55 Rs.</div></BODY></HTML>
I want to read data of div rate. i.e. I should get Content "Todays rate 55 Rs." So how can I make regex for this???

Why Does Custom HttpResponse Throw Exception On HttpResponse.End()
Jul 27, 2010I'm writing some code in which I need to use my own HttpResponse object to capture the output from a method on another object that takes an HttpResponse as a parameter. The problem is, this other object (which I cannot modify) calls HttpResponse.End(), which causes an "Object reference not set to an instance of an object" exception to be thrown. What can I do about this?
Dim myStringbuilder As New StringBuilder
Dim myStringWriter As New IO.StringWriter(myStringbuilder)
Dim myResponse As New Web.HttpResponse(myStringWriter)
someObject.doStuffWithHttpResponse(myResponse) ' calls myResponse.End() and crashes
Here's some more complete information about the error, thrown from the following code in a console application:
Dim myStringbuilder As New StringBuilder
Dim myStringWriter As New IO.StringWriter(myStringbuilder)
Dim myResponse As New Web.HttpResponse(myStringWriter)
Try
myResponse.End()
Catch ex As Exception
Console.WriteLine(ex.ToString)
End Try
Here's the text of the exception:
System.NullReferenceException: Object reference not set to an instance of an object.

Web Forms :: Unable To Read Web.config File/Object Reference Not Set To An Instance Of An Object
Nov 2, 2010I have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:
Object reference not set to an instance of an object.
[Code]....
It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.
My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?
Can An HTML Object Tag Be Placed Inside An HTML Form Tag
Oct 13, 2010I have a simple ASP.NET page that uses the VLC media player to play a video in IE. I also have four buttons to control the playback:
Play, Pause, Stop, and Mute
The four buttons call JavaScript functions that access the ActiveX control. When I click on any of the buttons, I get the following error in the JavaScript function:
"Microsoft JScript runtime error: 'vlc' is undefined".
However, if move the object tag for the vlc player outside the form tag, then the JavaScript works correctly, and I can control the video playback.
My question is why must the object tag be outside the form tag for this code to work correctly?

Read A Value From Html?
Dec 20, 2010I am new to asp.net. I need to send a value from send.html to get.aspx.cs
In send.html, I have
<a href="<%=var%>">The Link</a>
where the value of var is anotherPage.html
how do I get the value of var from send.html when send.html calls get.aspx?
Many hours spent still can't figure out. I probably could make the url like get.aspx?link=<%=var%>.... and then use Request.QueryString["link"] in get.aspx.cs to retrieve it, but shouldn't there be an easier way to look up the variable in send.html?

C# - Read Value From Code Behind On Html Page?
Mar 3, 2011Solution: I end up creatting a WCF that accepts a get/post request, then place JQuery within the html page that retrieves the value and hands it off to the web service
I have a html page like below where I will be doing posting to a web site for registrations and my credentials are not suppose to show on the client side.
My question is how/what is the best way of reading the values from code behind or web service or any other way ?

Use HttpResponse.End() For A Fast Webapp?
May 30, 2010HttpResponse.End() seems to throw an exception according to msdn.Right now i have the choice of returning a value to say end thread(it only goes 2 functions deep) or i can call end().
I know that throwing exceptions is significantly slower (read the comment for a C#/.NET test) so if i want a fast webapp should i consider not calling it when it is trivially easy to not call it?
-edit- I do have a function call in certain functions and in the constructor in classes to ensure the user is logged in.So i call HttpResponse.End() in enough places although hopefully in regular site usage it doesn't occur too often.

View 4 RepliesHow To Read Web.config App Key Settings In HTML Markup
Oct 30, 2010I have an ASP.NET site which uses a 3rd party activeX control. I have to pass a few parameters to the OBJECT tag in the HTML page. If i hardcode these parameters into the HTML everything works.
I would like to place the parameters in my web.config with app settings "key/value" pairs.
My problem is i cannot read the app key setting in the HTML markup to succesfully pass them in as parameters. I can read them fine from server side code behind.
What's the correct way to read these settings in the client side HTML markup ?

Web Forms :: Can Use HttpResponse From An Ascx File
Feb 19, 2011I am looking to render excel from an web control. I have code that works from a web page, but when I run it in an ascx.cs file it doesn't do anything.
Is there something about being in an ascx that makes a difference?
Here is my code:
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=file.xls");
Response.ContentType = "application/vnd.ms-excel";
Response.BinaryWrite(result);
Response.End();
Response.Flush();
Intercept What's Being Written To HttpResponse.OutputStream
Feb 17, 2010I am working on a tool which audits access to existing web application. Existing app does not have any hooks in place, but my plan is to inject an IHttpModule by modifying web.config and log whatever I need to log during EndRequest event.
What I'm struggling with right now is: I cannot intercept what is application writing to an output stream. I need to know what output does the application send to the client. Originally, I hoped I could run a code in BeginRequest to replace HttpContext.Response.OutputStream with a stream of my own, which would be flushed to original stream during EndRequest, but the stream only has a get accessor, so I cannot replace it.
I could of course use reflection to assign to private member of HttpContext.
C# - How To Read HTML Content Of Ajax Based Website
Mar 7, 2011I would like to know how the HTML source of ajax based sites can be read using HttpWebRequest / HttpWebResponse (That is reading the contents of a website at server side). The problem that I'm facing is that I'm unable to read parts of the webpage which uses Ajax or stuffs like UpdatePanel.
My application is in ASP.NET / C#, so can't think of using stuffs like Browser control or mshtml.dll since I would not be able to serve multiple requests.
