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.

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()

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.

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();
Response.Flush();

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

We have two production server, both having Windows 2008. now one server acting as the storage server and other server will work as web server which having the IIS (here IIS7). Now, I have to deploy the application on the storage server and in web server I have to configure the application in IIS with the path of network drive (here network drive means path of the folder at storage server). At here I had provide the full path like \ servernamedrivename$foldername, and also provide the credential at "connect at" button.Now when I open the page it will display the page but with the following error.
Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

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.

I have inherited a project which has many .ddl file's, I just need to get access one of them. I have managed to amend the .ddl file by using Reflector which outputted all the files into a specific folder on my C: drive. So now I have a bunch of files outside of my project. How can i recompile these files to create the new .ddl file so that i can overwrite the old one in my project? I have tried adding the new files as a new class project and building the site again, but no luck.

I have the following code that creates a new Excel file in my C# code behind. When I attempt to save the file I would like the user to select the location of the save.
In Method #1, I can save the file my using the workbook SaveCopyAs without prompting the user for a location. This saves one file to the C:Temp directory.
Method #2 will save the file in my UsersDocuments folder, then prompt the user to select the location and save a second copy. How can I eliminate the first copy from saving in the UsersDocuments folder?
Excel.Application oXL;

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?

I have two buttons ... one is insert btn another one is fileupload btn.
In the fileupload btn i creat a code in blow. I can upload the file successfully.
I need to insert a file in sql by using insert btn. For that I can create a insert query every thing but I cannot access the string filename value in the insert btn. So how I get the string value for insert btn. I mentioned the insert query also.
protected void UploadButton_Click(object sender, EventArgs e) {
string filePath = FileUploadControl.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string ext = Path.GetExtension(filename);
string contenttype = String.Empty;
[Code] ....
Insert Btn:
protected void btnInsert_Click(object sender, EventArgs e) {
cmd = new SqlCommand("insert into emp(FileName,ContanType, Data)values(@FileName, @ContanType, @Data)", con);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("@FileName", filename);
cmd.Parameters.AddWithValue("@ContanType", contenttype); cmd.Parameters.AddWithValue("@Data",bytes);
con.Open(); cmd.ExecuteNonQuery();
con.Close(); Response.Redirect("Default.aspx");

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.

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 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???

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'm new to asp.net and C# really, mostly just done windows apps in VB.net.
Also, trying to move from Crystal Reports to SSRS.
I found some code to render a SSRS report as a pdf. But this is saving the pdf locally. I have code that opens the report after it's saved, in the browser.
Rather than save the "results" locally, how to I go about just opening file in the browser.
Code:
results = rsExec.Render(format, deviceInfo,
out extension, out encoding,
out mimeType, out warnings, out streamIDs);
