I am using the code below which I have found on one of the forums to download a file in remote server. it seems it is working. However, the downloaded file is corrupted and I cannot unzip.

I'm trying to force a large (200+ MB) file to download that's on a remote server. The problem is that I can't use the "WriteFile()" function, since I'm not using a virtual path. Then, when I try:
Response.AppendHeader("content-disposition",
I have a remote xml file like [URL]
I would like to write a program to download it to local with progress bar.
I'm trying to download remote file using C# (ASP.NET). The problem is when I browse to the file download URL - it downloads perfectly. When I try the WebClient.DownloadData(url) I get "no data to show" response.
If I browse using the built-in VS2010 browser I still get this "error" message.
The file link is: [URL](CSV file)
i want to download file from other website to on my location and i used code below
Dim wc As New System.Net.WebClient

PathUrl,fileName both are correct m 100% sure.
after execution of these 2 line my browser progress-bar goes in to wait state like something is retrieving.but file not download any where.what should i do next?

long sz = fi.Length;
Response.ClearContent();
Response.ContentType = MimeType(Path.GetExtension(fName));
Response.AddHeader("Content-Disposition", string.Format("attachment; filename = {0}", System.IO.Path.GetFileName(fName)));
Response.AddHeader("Content-Length", sz.ToString("F0"));
Response.TransmitFile(fName);
Response.End();
}
public static string MimeType(string Extension)
{
string mime = "application/octetstream";
if (string.IsNullOrEmpty(Extension))
return mime;
string ext = Extension.ToLower();
Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);

mime = rk.GetValue("Content Type").ToString();

View 1 RepliesI 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 have used this example when exporting data to PowerPoint:
I have modified the GenerateSlidesFromDB() method:
public void GenerateSlidesFromDB()
{
string slideName = @"C:UsersxDesktopoutput.pptx";
File.Copy(@"C:UsersxDesktopTest.pptx", slideName, true);[code]....
As you can see I overwrite the placeholder with "Test User", and it works like a charm.I need to add an image (as a placeholder) to this pptx-file. When I do that (and run the code again) I get a corrupted pptx-file?
Error message: PowerPoint removed unreadable content in output.pptx. You should review this presentation to determine whether any content was unexpectedly changed or removed.
Edit: If I try the original code (which is slightly modified since I dont have Adventureworks), I get some other kind of error message:
This file may have become corrupt or damaged for the following reasons: Third-party XML editors sometimes create files that are not compatible with Microsoft Office XML specifications.
The file has been purposely corrupted with the intent to harm your computer or your data. Be cautious when opening a file from an unknown source.
PowerPoint can attempt to recover data from the file, but some presentation data, such as shapes, text,and formatting, may be lost.
Do one of the following:If you want to recover data from the file, click Yes.If you do not want to recoverdata from the file, click No.
In our application, we allow user to upload documents which can be PDF, Doc, XLS, TXT. Uploaded documents will be saved on web server. We need to display link for each document user uploaded and when user click on that link, it should open relevant document. it is expected to have required software to open relevant documents.
To upload document, we use saveAs method of FileUpload control and it works absolutely fine.Now, how to view it?I believe, i need to copy/download file to local user machine and need to open it using Process.Start.For that i need to find user local temp directory. if i put path.GetTempPath(), it gives me web server directory and copy file there.
File.Copy(
sPath + dataReader["url"].ToString(),
Path.GetTempPath() + dataReader["url"].ToString(),
true);
This below code i have used in my aspx page for file download.
Response.AppendHeader("content-disposition", "attachment; filename="" + emailAttachment.FileName + "";");
Response.ContentType = "application/octet-stream";
Response.OutputStream.Write(emailAttachment.Data, 0, emailAttachment.Data.Length);
Response.End();
This block of code display Download file Dialog for Open or Save the attached file.It's working fine in Mozila Firefox and IE8 but doesn't display Download file Dialog box in IE 7
I have made an application where I am displaying the .pdf , .doc , .docx files. These files are uploading from an Admin Panel.When user place a mouse pointer on download icon provided in front of every file, it shows the complete path where it’s get saved.I want to avoid this path visibility even when user place mouse on download icon and even if it Inspect an element (as most modern browser will have this functionality).
View 1 RepliesAfter upload a pdf file (order.pdf) to remote server in UNC format, I used code below to open order.pdf file.Code is working in IE9 but not Chrome.Is there another way to open pdf file in remote server?
Dim fullpath As String = [String].Format("file:///{0}", "webserverorderorder.pdf")
Response.Redirect(fullpath)
I have a simple 'file download' generic handler which sets the response contenttype and headers before sending the file through the same response.
I also have Response.Cache.SetCacheability(HttpCacheability.server) set in the global.asax.
As I have noticed from various sources, Internet Explorer doesn't like this no-cache setting and gives an error when trying to download the file (requested site unavailable or cannot be found).
I thought maybe I could override this setting in the .ashx page, so I alter the response's cacheability setting to public. This did not solve the issue. removing the line from global.asax does solve the problem but obviously affects the whole site.
Is there a way of setting the cachability just for my generic handler?
In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Disposition", "attachment;filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.End();
This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:
HttpResponse response = HttpContext.Current.Response;
response.ClearHeaders();
// Setting cache to NoCache was recommended, but doing so results in a security
// warning in IE6
//response.Cache.SetCacheability(HttpCacheability.NoCache);
response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.Flush();
response.End();
However, I don't believe that any of the changes made will fix the issue.

I calculate the total size of my PDF file which is mentioned below. What does this return? When I download a 2KB file, it returns a size of 2KB, which is correct. But when I download 2 files each of size 2KB, then the total size it returns is 2.16KB. Is that correct? Should it return 4KB?
