Web Forms :: Client Download .csv File From Server Using Response.TransmitFile?

Sep 3, 2010

I am using the code below to enable clients to download a .csv file from my server.

The problem I am having is that when the file is saved to the client computer the file name is prefixed and suffixed with an underscore which leads to a file type of .csv_ which is obviously not a recognised file type.

How can I strip the underscores from the file name at the transmit stage?

Dim FileName As String = LstBox1.SelectedItem.ToString
Dim FilePath As String = "~/temp" & FileName
Response.Clear()
Response.ContentType = "text/csv"
Response.AddHeader("Content-Disposition", "attachment; filename=" & FileName & "")
Response.TransmitFile(FilePath)
Response.End()

C# - Download .xlsx File Using Response.TransmitFile()?

Feb 16, 2010

I'm working on some code that generates an Excel spreadsheet server-side and then downloads it to the user. I'm using ExcelPackage to generate the file.

The generation is working just fine. I can open the generated files using Excel 2007 with no issues. But, I'm having trouble downloading the file with Response.TransmitFile().

Right now, I have the following code:

//Generate the file using ExcelPackage
string fileName = generateExcelFile(dataList, "MyReportData");
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.ContentType = "application/vnd.xls"
Response.Charset = "";
Response.TransmitFile(fileName);

When Excel 2007 opens the file downloaded as above, it gives the "file format doesn't match extension" warning. After clicking past the warning, Excel displays the raw xml contents of the file. If I change the file extension, like so Response.AddHeader("content-disposition", "attachment;filename=FileName.xlsx");
Excel 2007 gives an "Excel found unreadable content in the file" error, followed by a dialog that offers to locate a converter on the web. If I click "no" on this dialog, Excel is able to load the data.

I've also experimented with different MIME types, like application/vnd.ms-excel and application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, combined with file extensions of .xls and .xlsx. All combinations result in one of the two behaviors mentioned above. What is the correct combination of file extension and MIME type to use in this scenario? What else could cause this failure, other than an improper MIME type or extension? FYI, this is occurring with Visual Studio's built-in development web server. I haven't yet tried this with IIS.

Web Forms :: How To Use Httpcontext.response.transmitfile Or Other Method To Download A File From A Network Drive

Feb 25, 2010

Does anyone know how to use httpcontext.response.transmitfile or any other httpcontext function to download a file from a network drive instead of local drive?

When I tried to use context.Response.TransmitFile(DownloadPath) to download files, the DownloadPath has to be local drive. If it's a network drive, the download failed.

C# - Response.TransmitFile Failing On First Download?

Oct 19, 2010

I have some code on an aspx page then when users loads the page it starts downloading a zip. Looks like this:

Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileSaveName);
Response.TransmitFile(zipPath);
Response.End();

The problem is the FIRST time this is hit I get the following error:

The zip file exists and is not in my wwwroot. If I refresh the page the file will download fine.

If I wrap the code in a Try Catch I get a System.Threading.Threadabort exception with the message:

Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.

NOTE: I actually get that exception every time. I guess its just to do with the Response.End

Web Forms :: Response.TransmitFile --- Open A File From DataBase And Send It To Browser?

There are bunch of files stored in a DataBase as varbinary/image data. I am writing a program to extract these file data and send them to the browser so file can be opened or saved. My method is,

[code]....

BUT this method creates a file in the Server and then transmit to the browser. Means 100s of files will be created in the server when I open 100s of files with this process, naturally I want to avoid that.

Is it possible to do this without creating a copy of the file in the server ?

C# - Using Response.TransmitFile For Physical File Not Working?

Sep 27, 2010

I am trying to user the Response.TransmitFile() to prompt a download.

I have read a number of posts on the issue and based my method off Rick Strahl's blog [URL]

The only difference (that I can tell) is that I am targeting a physical file outside of the virtual directory.

This code is called in an ajaxified radgrid... I wonder if the response.transmitfile doesn't work with ajax calls?

MVC :: Response.TransmitFile Zeroing Out Part Of The Result File?

Apr 8, 2010

I have an MVC controller that returns a file via the Response.TransmitFile

I works splendidly with small files. I noticed with larger files that after the client app receives the file, everything in the file from offset 10000 (hex) to the end of the file is zeroes. The resulting file is the correct length, its just that everything from 1000 on is zeroed out. BTW, WriteFile does the same exact thing.

Download XML File To The IIS Server Not To The Client?

Oct 5, 2010

I'm trying to do the following in ASP.NET (with c#):

1. On page Load, download an XML file from a different website to the IIS server, in a subdirectory of the application directory called "downloadedFiles"

I know that WebClient.DownloadFile() can download a file, but this only seems to download the file to the client's machine. I am interested in downloading it to the actual IIS server (so that it can be utilized throughout the lifetime of more than one session). Does anyone know how this could be performed?

Specifically, I'm trying to download an XML file from a website (as an example: [URL]) . How could I download that XML file onto my actual IIS server?

AJAX :: How To Upload A File From Server To Client Without Attaching It To The Response

Mar 22, 2011

Basically I have to generate a rather large XPS document serverside and send this back to the client.

The issue I have whilst trying to do this is because the XPS document needs to be created on a STA thread, so either the response is sent back before the async operation is complete (in which case I can't attach the file using the transferfile method) OR I have to wait until the Async thread has completed and then I can send the file using the transferfile method (but this leaves the current page locked out for quite a while).

Web Forms :: Response.TransmitFile Virtual Directory?

Sep 21, 2010

I can use Response.TransmitFile on my p.c. using VS2008 fine. But when I moved my code over to the server it won't work. Does the path have to be a virtual directory?

Lets assume you have 1 serverA with dir D:ExcelReports and another serverB thats the webserver. So to transfer a file you would need something like Response.TransmitFile(D:ExcelReports) ?

Web Forms :: Calling Response.TransmitFile From Window Dialog?

Feb 11, 2010

I create a window dialog by calling window.showModalDialog;

In that dialog I want to execute a Response.TransmitFile like the code below. The code works fine from a non dialog window. However it just hangs if I call it from the modal dialog page. No error messages. I just doesn't do anything. Is there something else I need to do to get this to function in a dialog window?

string thePath = "c:\temp\New Text Document.txt";
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + "New Text Document.txt");
Response.TransmitFile(thePath);

C# - Using Response.Filter With Response.TransmitFile?

Aug 10, 2010

I'm using Response.Filter in order to implement stream compression in accordance with HTTP Request Header Accept-Encoding

Here's the important stuff:

if (AcceptEncoding.Contains("deflate") || AcceptEncoding == "*")
{
HttpApp.Response.Filter = new DeflateStream(PreviousOutputStream, CompressionMode.Compress);
HttpApp.Response.AppendHeader("Content-Encoding", "deflate");
}


By and large this works as intended. However, I'm in a situation where I'm using an ActionResult on an MVC Controller to serve up files to the user agent:

Response.Clear();
Response.Headers["Content-Type"] = contentType;
Response.Headers["Content-Length"] = contentLength;
if (Request.QueryString["dl"] == "1")
{
Response.Headers["Content-Disposition"] = "attachment; filename=" + fileInfo.Name;
}
Response.Flush();
Response.TransmitFile(fileInfo.FullName);

To be more exact, the action method returns new EmptyResult() after the Response.TransmitFile() call. This works exactly as intended without the Response.Filter modification.

In this situation, the response entity reaches the user agent garbled and unintelligible. FireFox's Poster addon shows empty entities or jumbled entities coming back.

Web Forms :: File Download Using Response.BinaryWrite() - Odd Behavior

Jan 8, 2010

I am using a gridview to display (open or save) files that have been uploaded into a SQL 2005 server. I have a templatefield within the gridview that contains a linkbutton that does a postback to GetUploadedFile.aspx that then fires the response.binarywrite() code. The code seems to work fine and opens/saves the files correctly. But once this has completed and I try and click on another button on the page, instead of doing the appropriate action it re-fires the getuploadedfile.aspx binarywrite code and opens up the "Open/Save/Cancel" dialog again.

Web Forms :: Load File From Database And Write A Response To Let User Download?

Mar 10, 2010

I am a newbie of asp.net.

The environment is .net 3.5 and C#.

There are files stored in sql server (datatype of column is varbinary in the database).

each record is in one record in that table (FILE_TABLE).

And there is another table (PATH_TABLE) to store the files paths.

for example,

when the user download the folder A (select an item on the tree and click a button on the client side),

there is one sub-folder B and two files A-1 and A-2.

in folder B, there is two files B-1 and B-2.

then, at the code behind (server), the server will get the files from the database and convert them (including the files and subfolders) to a .zip file (or other compressed files)

and then write a response (using the method HttpResponse.BinaryWrite(Byte[] xxx) )

to client side and let the user download.

after the download, the user can extract the compressed file and the structure of the folders and files keep unchanged.

Response.TransmitFile() Doesn't Appear To Be Working?

Sep 7, 2010

I am calling a [WebMethod] with a piece of JQuery. The aim of the following code it to sent a recently zipped file to the user's browser. When the user clicks the 'Download' button, an AJAX request is sent to the ASP.NET page with is supposed to send the zip file. Here is the code.

[WebMethod]
public static void DownloadAlbum(string folderToDownload)
{
string archiveDir = "";

some code...

HttpContext.Current.Response.ContentType = "application/zip";
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + path);
HttpContext.Current.Response.TransmitFile(path);
HttpContext.Current.Response.End();
}

When this runs, nothing is sent to the browser, but no exceptions are thrown either. I'm unsure as to what is going on and why the file is not downloading. The 'path' DEFINATELY has the correct address, and when the address of the file is hard-code the same happens.

Export To Excel Using Response.TransmitFile()?

Oct 5, 2010

using asp.net 3.5 I am trying to generate a formatted excel spreadsheet and the way i am doing it is:1.Format the excel sheet with data 2.Save it as an xml spreadhseet 3.View it in notepad/textpad and remove the "data" from the xml and have a content holder
such as "DYNAMICDATA" 4.Build dynamic xml for data and replace the "DYNAMICDATA" place holder with this fresh data.5.have all this in a stringbuilderI m stuck here, I want to be able to Response.Write(stringbuilder)but it does not work, I have used the appropriate MIME types etc.However Response.TransmitFile() works when i just transmit an xml spreadsheet to browser.but Response.TransmitFile() takes a file as an argument, I can create a temp file write the created xml and then transmit but that just seems like a heavy overhead.Is there a way i can without creating a file, just transmitXml() using the stringbuilder contents and let the user save the spreadsheet.

C# - Calling Response.TransmitFile() From Static Method

Feb 16, 2010

I have a number of pages which need to support exporting data to an Excel spreadsheet. I can generate the Excel files just fine, but I'm trying to work out how to abstract this behavior so it's easily reusable from all of the pages where I need it. My current idea is to use a static utility method, as follows:

[Code]....

The click handler where I'm calling SendExcelFile looks like this:

protected void lnkExport_Click(object sender, EventArgs e)
{
List<List<string>> dataList = GatherDataForSpreadsheet();
Utility.SendExcelFile(this, "fileNameForDownload.xlsx", dataList, "MyReports");
}

This code works just fine as an instance method of the calling page. As a static method, though, it doesn't work at all. When I click the button that invokes this, the browser shows the loading animations indefinitely, but never prompts for a file download.

EDIT: If I remove the call to File.Delete() at the end, the method works as expected. Does Response.TransmitFile() do the transfer asynchronously?

EDIT 2: I just needed to call Response.Flush() before I deleted the file.
