C# - Is Normal To Push Data Into The Stream Before Click "Save"

Apr 2, 2010

I'm making tests with ASP.NET HttpHandler for download a file writting directly on the response stream, and I'm not pretty sure about the way I'm doing it. This is a example method, in the future the file could be stored in a BLOB in the database:

public void GetFile(HttpResponse response)
String fileName = "example.iso";
response.ContentType = "application/octet-stream";
response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);
using (FileStream fs = new FileStream(Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data"), fileName), FileMode.Open))
Byte[] buffer = new Byte[4096];
Int32 readed = 0;
while ((readed = fs.Read(buffer, 0, buffer.Length)) > 0)
response.OutputStream.Write(buffer, 0, readed);

When I open the url with the browser, appears the "Save File" dialog... but it seems like the server has started already to push data into the stream before I click "Save", is that normal? If I remove the line"response.Flush()", when I open the url with the browser, ... I see how the web server is pushing data but the "Save File" dialog doesn't come up, (or at least not in a reasonable time fashion) why?

When I open the url with a WebRequest object, I see that the HttpResponse.ContentLength is "-1", although I can read the stream and get the file. What is the meaning of -1? When is HttpResponse.ContentLength going to show the length of the response? For example, I have a method that retrieves a big xml compresed with deflate as a binary stream, but in that case... when I access it with a WebRequest, in the HttpResponse I can actually see the ContentLength with the length of the stream, why? What is the optimal length for the Byte[] array that I use as buffer for optimal performance in a web server? I've read that is between 4K and 8K... but which factors should I consider to make the correct decision. Does this method bloat the IIS or client memory usage? or is it actually buffering the transference correctly?

Why Does The Default Forms Authentication Cookie Have A Leading Period In It's Default Name

Mar 21, 2011

the default ASP.NET Forms Authentication cookie sets it's name as ".ASPXAUTH". Notice the first character is a period? Is there a particular reason for this? Like, does this have an impact on domain names or subdomains for the target domain.

Or is it purely some random thing an MS dev person came up with (maybe to help out the ordering of the cookies, when they were debugging or something .. as text with periods prolly get listed before other strings)?

Web Forms :: Cannot Stream File To Desktop From Pop Up Window

Sep 23, 2010

I changed an app so one of the edit screens opens as a pop-up window via showModalDialog. Previously everything was done in the same window and more back and forth navigation was required. The pop-up provides greater continuity. Unfortunately, as a pop-up, files will not stream to the desktop. If I bring up the page by entering a URL on the address line, so it is not a pop-up, files stream to the desktop OK.

Streaming a file to the desktop is done as follows:


This causes an open/save/cancel dialog to appear in the browser. Does anyone have an idea why a file cannot be streamed to a pop-up window? To get pop-ups to work I always include


in the header. That way I can open other pop-ups such as warnings and database error messages from a prvious pop-up.

Web Forms :: Stream A File And Update Page?

Jul 28, 2010

I don't think there is a way around this but figured I'd ask... We have an application where a user can generate PDF documents that are streamed to the browser. There is some additional functionality going on behind the scene and I would like to be able to display a message to the user (via updating a literal tag on the page). I don't get any errors when doing this but the page isn't updated and the message isn't displayed. My guess is that streaming the document blocks any other content from going down to the client. In particular, we're using CeTe Dynamic PDF and calling one of their methods but I think it's essentially just doing a Response.BinaryWrite to stream out the PDF.

Web Forms :: Open Save Dialoge From Button Click To Save Including CSS?

Feb 4, 2011

My page (which basically contains a pair of Repeaters) renders and is displayed to the user.I'd like to have a "Download" button on the page which, when clicked, will propmt the user to save the page locally as an html file without losing any of the CSS formatting.

My CSS files are linked to via a Master Page.Currently, I have the button linked to some javascript that open will the Save As dialog, but all of the CSS formatting is lost, and it saves the page .I'm assuming that the button will need to open a new page which will re-create the data for the Repeaters and then save using StreamWriter, but I'm not exactly sure if that's right or how best to do it.

Web Forms :: Reading A File Into Stream And Saving It To A Location?

Oct 8, 2010

I have a third party CMS system that can create forms but can't manage true File upload capabities. I am able to get users brows for thier file and have the value submited to my custom .net code behind page for processing. So I end up with like "C:somefilefoldersomefile.doc".

But on my processing page I want to read this file (like the file uploader) and save it to a location. I tried using the file uploader control (but have it not visible) but realized I can't preset it as I was planning to set it and do the normal processing from there. Is there another way to do this?

Forms Data Controls :: Deserialing Binary Stream And Loading To Chart?

Nov 1, 2010

I have a MS Chart Control and I'm trying to serialize the chart to view state. When teh page postbacks, I wnat to de-serialize the chart from ViewState, then load it back to the Chart's serializer. When the Chart1.Serializer.Load is called, I get an error message stating Data at the root level is invalid, line 1 position 1.

So here's what I have:

Chart1.Serializer.Format = System.Web.UI.DataVisualization.Charting.SerializationFormat.Binary;
Chart1.Serializer.Content = System.Web.UI.DataVisualization.Charting.SerializationContents.All;
ViewState["myStream"] = myStream.ToArray();
On postback, when the routine is called:
System.Byte [] byters;
System.IO.MemoryStream myStream = new System.IO.MemoryStream();
if (ViewState["myStream"] != null)
byters = (System.Byte[])ViewState["myStream"];
myStream.Position = 0;
Chart1.Serializer.Load(myStream); // this line throws a XmlException - data at the root level is invalid. line 1 , position 1.

The length of the stream was 15,518 and capacity was 16,384 when it made the save. On postback, both capacity and length became 15,518.
