I 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'm creating a custom module and I need to be able to read the html output that's written to the HttpResponse object. Can anyone provide direction on this?
I'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. at System.Web.HttpResponse.End() at ConsoleApplication1.Module1.Main() in C:Documents and Settingsjoe.userLocal SettingsApplication DataTemporary ProjectsConsoleApplication1Module1.vb:line 10
How do I just get the first line of a multiline textbox? Either that or delete everything after "<br/>"? I tried something like this but it doesn't work:
HttpResponse.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.
I 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.
User fills out this large page which is dynamically created based off DB values. Those values can change. When the user fills out the page and hits submit we want to save a copy of the page as html on the server, this way if the text or wording changes, when they go back to view their posted information, it is historically accurate.
So I basically need to do this
protected void buttonSave_Click(object sender, EventArgs e) { //collect information into an object to save it in the db bool result = BusinessLogic.Save(myBusinessObject); if (result) //!!! Here is where I need to save this page as an html file on my servers IFS!!!! else //whatever Response.Redirect("~/SomeOtherPage.aspx"); }
Also I CANNOT just request the data from the url because query string parameters are a big no no in this case. The key to pull the database info up (at its highest level) is all in session so I cant just request a url and save it.
I have this following code for bringing page attachments to the user:

The problem is that all supported files works properly (jpg, gif, png, pdf, doc, etc), but .docx files, when downloaded, are corrupted and they need to be fixed by Office in order to be opened.
At first I didn't know if the problem was at uncompressing the zip file that contained the .docx, so instead of putting the output file only in the response, I saved it first, and the file opened successfully, so I know the problem should be at response writing.
I'm working on a functionality in my asp.net web site that enables the user to download some files as a zip file. I'm using the DotNetZip library to generate the zip file.
Now, if anything goes wrong, say the Utils.ExportToZip method fails, I want to present an error message to the user and not the download dialog. Do I have to remove some data from the Response object in order to cancel the download operation?
An user posts this article about how to use HttpResponse.Filter to compress large amounts of data. But what will happen if I try to transfer a 4G file? will it load the whole file in memory in order to compress it? or otherwise it will compress it chunk by chunk?
So at the same time I'm reading, I'm compressing and sending it. Then I wanna know if HttpResponse.Filter do the same thing, or otherwise it will load the whole file in memory in order to compress it. Also, I'm a little bit insecure about this... maybe is needed to load the whole file in memory to compress it... is it?
I have an issue with trying to create a Pdf file from my webpage. Basically, everythig involving creating the Pdf (using iTextSharp) is done, and I'm doing this as a File Stream (i.e, I'm saving the Pdf on local machine). Now what I'm trying to do is create it as a Memory Stream (i.e, open the Pdf from the browser). I was able to do this earlier when I wa still at the 1st version of the application, and all of the code behind was incluced in my .aspx.cs file. But now, I've kept the code in the .aspx.cs at a minimum and put the cude in classes and I'm creating onjects of thoses classes from the .aspx.cs
The problem is that the code from creating the Memory Stream is in a class as follows:
[Code]....
As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs
I have an action for which the output is fairly static, until another action is used to update the datasource for the first action. I use HttpResponse.RemoveOutputCacheItem to remove that action's cached output so that it is refreshed next time the user loads it.Basically I have an action like this:
[OutputCache(Duration=86400, Location=OutputCacheLocation.Server)] public ActionResult Index() { return ... }
I am trying to create an instance of System.Web.HttpResponse to send the uers to another website.I am doing some other stuff in my vb.net that does not let me use the regular Response.Redirect.when I do Dim myRsp As System.Web.HttpResponse = New System.Web.HttpResponseit complains about a textwriter.
This is my Controller Action which takes a Page entity from database and shows it in the Show.aspx view using the "Site.Master" master page:
[Code]....
This is the "Show" view rendering "Page.Title" in the "MainContent" content placeholder:
[Code]....
And this is the "Site.Master"
[Code]....
Using this approach i can show "Page.Title" in Show.aspx using any master page that has a "MainContent" placeholder, but my real goal is if i can when i choose the MasterPage for that particular Page to also see a list of available ContentPlaceHolders and when i choose one to then render "Page.Title" in that particular ContentPlaceHolder.
My application for "Members subscriptions registration" working online and different users using it.
Database type is Mssql Server 2008 R2, Size is around 1 Gb
What happen exactly there is specific record delete from table "Members" in random times, For example I add 100 new subscriptions with around 800 records and make confirm and checking next day find it loss 3 records find it deleted.
I checked all the applications no any delete query, I removed all delete query from application to make sure no any delete also I save any delete query happen in system inside table for log.
My Company registered in certain services on the Web and are relying on the company's Ip to use these services, Director asked me to allow some staff to enter these sites from outside the company,after authorized staff enter to comany's site, How could they use the company's Ip to allow them to browse services sites ? Do I need to use a method such as proxy sites like youtube proxy? or there is another way?How do I do this in asp.net?

I am unsure how to quickly check a set of returned values for a specific value. Given the following:
[Code]....
I then want to check all the returns values in locs for a specific value. I know I could build a foreach loop that would walk through every return data value in locs to see if it matched, but I was hoping to use something simpler.

I tried to search for this already as I am sure it has been asked before, but I apparently lack the proper search keywords.
