My web application is opening up a word document using Response -
Code:
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + CreateObjectiveDocumentName(strLetter) + ".doc");
Response.ContentType = "application/vnd.ms-word";
Response.Charset = "";
Response.ContentEncoding = System.Text.Encoding.Default;
Response.WriteFile(strFinalDocName);
Which works fine.
However, is there anyway to open the word document in the background?

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?
Here is my code snippet:

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.

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.

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.

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()

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 ?

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.

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.

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.

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

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.

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) ?

I'm trying to create an ASPX page that displays both an HTML message ("Please wait, your file transfer will begin momentarily") and also commence transmitting a file. I'm trying to avoid making the user open the page, and then clicking a Download buttonIt seems like this may be possible with a "Multipart/mixed" MIME type. Elsewhere I think I read that ASP.NET won't support this.

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);
Response.End();

i am trying to have a download on my page. I have implemented the code below but code execution stops after the download message pops up, even if i press save or cancel, nothing happens after that.
[Code]....
I have tried it a few times without Response.Clear() and Response.End() but it didn't make any difference to take these off. Is there anyway I can achieve this without having to using an IFrame?

I'm using Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.HtmlEncode(FileName)); to pop a 'open/save file' dialog for the users, so that they can download an file on to their local machines.
This is working good normally in IE7,But on IE6 the file is not opening when user click on the open button in 'open/save file' dialog. I gone through the net and found that Response.AddHeader("Content-Disposition", "inline; filename="+Server.HtmlEncode(FileName)); should be provide to work that in IE6,and its works fine..
But the issue is most of the files that can open in browser opens on the page itself.. ie user on a mail page and click download an image file it opens there,, i need it to open in another window as in case of IE7 what can i do... other files that cannot open in bowser open with current application in system ie(word,excel etc)..
The Code i used is here....
Response.AddHeader("Content-Disposition", "attachment; filename=" +FileName);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = ReturnExtension(file.Extension.ToLower());
Response.TransmitFile(file.FullName);
Response.End();
private string ReturnExtension(string fileExtension)
{
switch (fileExtension)
{
case ".txt":
return "text/plain";
case ".doc":
return "application/ms-word";
case ".xls":
return "application/vnd.ms-excel";
case ".gif":
return "image/gif";
case ".jpg":
case "jpeg":
return "image/jpeg";
case ".bmp":
return "image/bmp";
case ".wav":
return "audio/wav";
case ".ppt":
return "application/mspowerpoint";
case ".dwg":
return "image/vnd.dwg";
default:
return "application/octet-stream";
}

I have uploaded all my pages in httpdocs, and created a data bese ... I have also chaned the connection string acordingly but still i am geting following error on opening the page....:-
Server Error in '/' Application.
Runtime Error
Description:
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
[Code].....
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

I'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
