Saving HttpResponse / Request To File System

Mar 15, 2010

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.

Why Does Custom HttpResponse Throw Exception On HttpResponse.End()

Jul 27, 2010

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.

DataSource Controls :: Uploading Multiple Files To File System And Saving Paths To Database With One Button Click

Jan 20, 2010

I creating a page where our clients can view advertising images and then able to download the images in different file formats. So I need the images and the different download types all saved into the same row in the database so that when I go to display them on the page when they select a picture the right download links will be there. So here where my problem comes in, I don't know how to code it so that I can insert mulitiple file paths into the database at once. The images are saved in a table called images. The downloads are saved in a table called Image Downloads.

Here is the code for the page I have it coded to submit the images to the database but not sure how to add the rest. I have got three different sql datasources for each table not sure if that's the way to go.

Feb 19, 2011

I 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();

Web Forms :: Accessing HttpResponse Page.Response From A Class Instead Of Cs File?

Oct 18, 2010

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:

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

Saving A File From MemoryStream?

I have a function that downloads an image from a DB, saves it to a Temp directory and passes the string back to an app that opens it. Ran fine with .NET 2.0, but throws a variety of exceptions in .NET 4.0. (like System.AccessViolationException was unhandled).It somehow seems to relate to the saved file still being locked.

Avoid Saving New File On The Disk?

Mar 8, 2010

I am using ASP.NET 3.5 with iTextSharp and I have the following code:

var templatePath = Server.MapPath(@"~/Templates/template1.pdf");
var newFilePath = Server.MapPath(@"~/TempFiles/new.pdf");
PdfReader pdfReader = new PdfReader(templatePath);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(newFilePath, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
pdfFormFields.SetField("Box1", "007");
pdfFormFields.SetField("Box2", "123456");
pdfStamper.FormFlattening = false;
pdfStamper.Close();
Response.ClearContent();
Response.Buffer = true;
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment;filename=new.pdf"));
Response.WriteFile(newFilePath);
Response.End();

The above code fills out a pdf file and saves the new file to the TempFiles folder. It then prompts the user to either save or open the file. Can I achieve the same functionality without saving the file to the TempFiles location?

How To Replace Request To PDF File To Redirect To Same File In Different Location

Dec 7, 2010

I have a virtual web folder that has large number of PDF Files (Leave Forms) submitted over the past 5 years.

The users and other applications have direct references to such files and on some cases, the PDF is referenced as embedded object.

Here is a snapshot of where the PDFs are stored:

So, the direct link to the PDF will look like the following:

[URL]

Becuase the PDFs are stored under a folder under the ASP.NET Web Application, it was a bad idea.

Now, I have to move them all to another location which is simply a virtual folder outside the Web Application.

All Leave PDF Forms have Unique URLs which is:

"SessionID" + "/" + "Leave-userid-start-date.pdf"

So, I need to replace the above link with the following after I move the PDF Files. I want the replacement to happen at the time it is requested from the Client Browser. The new URL will look like the following:

[URL]

So, whether it is requester from IE from any other Object Tag or similar, then the input URL should be replaced with the new URL as shown above.

Use HttpResponse.End() For A Fast Webapp?

May 30, 2010

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.
