How to read/write GIANT text file with no line breaks


I have to process giant XML files that are 6GB+ in size.  The problem is that there are no line breaks in the file, and the XML is improperly formatted (no root element).  Therefore I can't use the XML class to read the file, and I can't open the file in any text editor or even "Type" it in a command window because the 1 line in the file is over 6GB.

The file contains UTF8 characters.  What I want to do is first write a program just to read and display 100 characters at a time so I can look at the contents.  Next I want to be able to create a new file, write a root element, read/write the contents of the file and then write the closing root element.

Can anyone provide a code snippet of how to read and display the file contents 100 characters at a time.  I can then figure out the rest.

Using response.outputstream.write to stream large file fails in firefox



I have some code to stream files (for security of the files), the code works for all files in IE, and small files in firefox. but If the file is large (eg 750Mb) firefox hangs before it shows the open/save dialog box. 

However if i take out response.clearheaders and the response.flush in the code it does download but all the files downloaded by firefox are corrupt because the file size is too large.   Filenames are guids but I took the "-" out incase that was an issue.

If any one can shed some light on this I would be very grateful.

Function is Below. 


Private Sub StreamFile(ByRef response As HttpResponse, ByVal sFile As String)
            Dim fs As FileStream = Nothing
            Dim sFileName As String = Path.GetFileName(sFile)

            Dim oFile As New FileInfo(sFile)

                fs = New FileStream(sFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)

            Catch ex As Exception

            End Try


            'response.ClearHeaders() 'makes file size wrong in firefox
            response.AddHeader("Content-Length", oFile.Length)
            'To forcefully download, even for Excel, PDF files, reg

passing a response.write to a label


I'm trying to pass a calculation from a response.write to a label.

    Public Sub StartTimeDif()
        Dim dt As DateTime = Convert.ToDateTime(starttimeInput.Text)

        Dim ts As TimeSpan = dt1.Subtract(dt)
    End Sub

I want to pass (ts.minutes) to durationLabel

Response.Write(string.Format("", url));


Hello all,

Any suggestions are greatly appreciated...

Here is the website situation:

Webpage A: look & feel alignments are in the central of the screen.  It has a submit button.  The last code in the submit command() is this message subject:

Response.Write(string.Format("<script>window.open('{0}', '_blank');</script>", url));

where url = another webpage B.

The outcome is fine.  Webpage B is populated properly.  However, Webpage A postback as aligment to the left, it is no longer the center. 

I could not find a way to debug the issue.

Once again, thanks in advance.

_AppStart.cshtml: can't get response/request to write/read cookie?


currently, I'm setting up an HttpCookie in a "master" page (layout) and check wiehter I need to send the user back to some specific page depending on the value, if it has expired, etc.
Because the master layout page is not the 1st "page" code to process, I can sometime get runtime error because the cookie is already expired.

I thought I would move this part to the _AppStart.cshtml file but I can't get to read/write (Response/Request) the cookie there?

Should I do this in a _PageStart.cshtml in all my folders rather?

Response.BinaryWrite help needed


Hi all

Im new to .NET and stuck now, so i hope anyone can help my with my problem.

I have a MS SQL database where i have stored some documents as Binary data. I cant figure out how to retrieve them and show/download them in my browser.

I found some guides online and have try to put something together.


private void Write()
 int id = 0;
 string strID = Request.QueryString["id"];
 int.TryParse(strID, out id);

 var db = new ModelDataContext();
 var doc = db.DocumentDatas.Where(x => x.ID == id).FirstOrDefault();

 byte[] byteArray = File.ReadAllBytes(doc);


How do i fill the byteArray with the data?

Thanks in advance :)


Response.Redirect slow


I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:


takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";
Response.AddHeader("Location", url);

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

New off line application working with sdf file. Need advice


Hey Folks

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's
