View 2 RepliesWeb Forms :: Accessing HttpResponse Page.Response From A Class Instead Of Cs File?
Oct 18, 2010I 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:

As you can imagine, the compiler cannot recognise "Response" as it's in a seperate class instead of in .aspx.cs
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.

Cannot Create The Object Of Abstract Class
Apr 22, 2010We all know that, we cannot create the object of Abstract class.
But why it is so?
I mean, can anyone explain it with real time example?
Why Use Reference Of Abstract Class To Create Object
Jul 22, 2010Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.
TextWriter writer = new StreamWriter();
why can't we simply use :
StreamWriter writer = new StreamWriter();
Create Slim Version Of Large Object / Class
Jan 1, 2010I have a product class which contains 11 public fields.
ProductId
ShortTitle
LongTitle
Description
Price
Length
Width
Depth
Material
Img
Colors
Pattern
The number of fields may grow with attributes for more specific product tyes. The description may contain a large amount of data. I want to create a slim version of this product class that only contains the data needed. I'm only displaying 4 of the 12 fields when listing products on a category page. It seems like a waste to retrieve all of the data when most of it isn't being used. I created a parent class of ProductListing that contains the 4 fields I need for the category page
ProductId
ShortTitle
Price
Img
Then created a class of Product that inherits from ProductListing containing all product data. It seems backwards as "ProductListing" is not a kind of "Product" but I just started reading about inheritance a few months ago so it's stil a little new to me. Is there a better way to get a slim object so I'm not pulling data I don't need? Is the solution I have in place fine how it is?

View 1 RepliesHttpresponse - How To Handle Errors When Using C# To Create A Zipfile For Download
Oct 29, 2010I'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.
My code looks like this:
protected void OkbtnZipExport_OnClickEvent(object sender, EventArgs e)
{
var selectedDocumentIds = GetSelectedDocIds();
string archiveName = String.Format("archive-{0}.zip", DateTime.Now.ToString("yyyy-MMM-dd-HHmmss"));
AddResponseDataForZipFile(Response, archiveName);
try
{
string errorMessage = Utils.ExportToZip(selectedDocumentIds, arkivdelSearchControl.GetbraArkivConnection(), Response.OutputStream);
if (!string.IsNullOrEmpty(errorMessage)).......
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?
ADO.NET :: Unable To Create Object Variable For Linq Data Class?
Sep 23, 2010For some unknown reason I suddenly am unable to create an object variable for a Linq Data Class. If I create a new project and try the process again with the same database everything works as advertized.The code I am using is Dim db As New RoggDataContext which gives me an error on the object variable "db": Overload resolution failed because no accessibility 'NEW' accepts this number of arguments.I have looked inside every file in the Web Project like the web config to check the connection string, gobal, and designer.vb looking for any errors whit no JOY. I also tried to create a new form and code behind with a button and received the same error.This is mind blowing because as I already stated, I can create a new Web Site and the problem goes away.

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???
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.
