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 want to create a .doc-file in my code behind and let the user download it somehow. How can this be done in the simplest way without saving the file at the server? I heard MemoryStream can be used but I'm not exactly sure how.
I'm currently trying to write data (client machine) into a xml file where the user can save. However, I want the users to be able to decide on where they want to save this written xml file. Is there any controls or codes that I can use to allow the users to save the file?.
I need to create a .XLS file and put it available for download in my .aspx page. this file is needed to have information from database. I'm using Linq to SQL. So I need a C# code for reading from DataBase using Linq and create a .XLS file for download.
We're getting this weird exception when trying to create a BitmapDecoder off an ASP.Net response stream. This is the line of code that throws the exception:
BitmapDecoder dec = BitmapDecoder.Create( Request.Files[0].InputStream, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad);
Here's some info on the file being uploaded: Filename: bank statement.jpg, Content length: 266041, Mime type: image/jpeg
This is the exception stack trace:
System.IO.IOException: Cannot read from the stream. ---> System.Runtime.InteropServices.COMException (0x88982F72): Exception from HRESULT: 0x88982F72 [code]...
I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?
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(
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 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
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?
i m creating asp.net Mobile website page to download symbian .sis file to mobile ,but its not geting download properly.its working perfectly on desktop.
I am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?
I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. Any solutions about it?? I want this in my app asp.net: Read DATA from Oracle Uncompress file using FileStream and BZip2 Read file uncompressed and send it to asp.net page for download. When I read file from disk, Fails !!! and get OutOfMemory. My Code is:

If so, we're done if (nextByte == -1)............................
I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.
