I wrote an ASP.Net web page that will take a QueryString and stream a file to the client. The file is stored in a SQL Server database. Everything works great when I'm running the web site locally during development. When I run it in production from the server I can get a file through Firefox, but not Chrome. In Chrome I get Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error.See some other posts that mention this could be related to Content-Length, however, I can't understand why this would work in development and not production. For that reason I think there must be something else going on here.Here is my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Data_ID As String = Request.QueryString("Data_ID")
Using dt As New Enterprise_Error_Log.Field_FileDataTable
When user requests to download a document, I'm writing out a PDF file to HttpResponse using HttpResponse.OutputStream.Write method. It works in every browser except Firefox(3.5.8). In Firefox it sometimes displays the file and sometimes it displays the actual byte stream. When it displays a byte stream, http response is never finished. I see 'transferring data' status and the byte stream ends with EOF. After some time, I get 'connection was reset' window.
Here is response header:
HTTP/1.1 200 OK Cache-Control: no-cache Pragma: no-cache Content-Length: 103185 Content-Type: application/pdf Expires: -1 Server: Microsoft-IIS/7.0 X-AspNet-Version: 2.0.50727 Content-Description: stuff.pdf Content-Disposition: inline;filename="stuff.pdf" X-Powered-By: ASP.NET Date: Mon, 22 Feb 2010 16:15:38 GMT
I'm struggling with ASP .NET Validators JavaScript issue. Following function (part of framework generated code) tries to access validatioGroup attribute value using control.Field syntax. It works fine in IE, however in FF that value is always undefined. Consequently, validation always passes and my validation scenario is broken... Is there a way to get round it?
function IsValidationGroupMatch(control, validationGroup) { if ((typeof(validationGroup) == "undefined") || (validationGroup == null)) { return true; } var controlGroup = ""; if (typeof(control.validationGroup) == "string") { controlGroup = control.validationGroup; } return (controlGroup == validationGroup); }
If Not IsDBNull(ext) Then ext = LCase(ext) End If Select Case ext 'Case ".htm", ".html" ' type = "text/HTML" 'Case ".txt" ' type = "text/plain" 'Case ".doc", ".rtf" ' type = "Application/msword" 'Case ".csv", ".xls" ' type = "Application/x-msexcel"........................
I have an excel file in my Response Output stream. I can Open the stream as a file after a prompt, but it doesn't seem I can save it directly to a specified folder on my client.
I need to to export a file to the user. It takes 1-2 min to generate the file so I'd like to have the page go into a kind-of modal mode with a layover on the page and a 'Working' spinner showing. The problem is I can't make the modal stuff go away after Save File dialog is closed.
How can I remove the layover after the dialog is done?
i am using treeview controls... but its showing broken lines and also line not well aligned.. on expanding and also on loading...
i did replaced...

I created a one Java script calender. Its working fine in ie6 but its not working in firefox. I'm new to this java script so kindly give your suggestion as soon as possible.
After the implementation of ajax drag and drop, we have observed that which is working fine in IE and Firefox and not in chrome and safari, In Google chrome and Safari when we try to drag a module, the page getting scrolling to the top of the page.
On our site, I use the category (in Russian) in the querystring. E.g.: [URL] (I notice the link is not clickable here, you need to copy the entire link to view the result) If you paste this link in IE8, it is translated to cat=???? and it does not work If I paste it in FireFox, it works. It gets even more weird: the same URL is reachable from the homepage, and if I click the same URL in IE8 from the homepage it works fine (unless I click open in a new tab, that it is back to ????). I am using ASP.NET 3.5(C#)
I'm trying to get my site to play a flash video the first time, and only the first time, a user visits the site. Currently, I'm using ASP session tags to install a sessionid cookie into the users browsers.
<% Session("name")="blah" Session.Timeout=7 %>
This method works fine in FF and Chrome, but IE8 doesn't seem to want to accept the cookie. I've tested it with IE's lowest security settings possible ("Accept all cookies"), but it still does not create any cookie. Is there any other way to make it so that all browsers will take the cookie?
Assume we have the access to sth.avi on [URL] with a direct link.
e.g : [URL] Also we have a website => www.dl2.com.
Now, we wanna let some users to download sth.avi from [URL], but we don't have enough space on [URL] to save sth.avi. Is it possible in ASP.NET for us to read sth.avi from www.dl.com as streaming file and share it without saving the file on our domain.
P.S: I don't wanna share this link [URL], actually I wanna share something like this link [URL]
I have made a WCF web service that streams a 200 mb zip file. how i can read this stream at my client and then give option to the user to download that
I am trying to filestream to my hosting Companies sever.I have tried the below expecting it would not work. How can I find the correct path.Could not find a part of the path 'C:ERAPDFERA202.60.64.136.1.pdf'.
Exception Details: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:ERAPDFERA202.60.64.136.1.pdf'.
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:
[Code]....
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
[Code]....
in the header. That way I can open other pop-ups such as warnings and database error messages from a prvious pop-up.
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.
I have a wcf service that is used to download files. Its working alright (finally), but i can see that when it downloads the CPU usage goes around 75%.Client Code
FileTransferServiceClient obj = new FileTransferServiceClient(); Byte[] buffer = new Byte[16 * 1024]; CoverScanZipRequest req = new CoverScanZipRequest(
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?
The Div can be visible or invisible in IE, but not in FireFox, the main purpose is: when user typing text in a password textbox, if the CAP LOCK is one, show the div:
