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 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 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 want to download file from other website to on my location and i used code below
Dim wc As New System.Net.WebClient
wc.DownloadFile(pathUrl, fileName)
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?

}

View 13 RepliesI have an off-line project. User uses a laptop to input data off line into local SQL server express. Once connected to domain (on line), local data will sync with remote SQL server using sync framework. (It is done, works fine)
One job left:
Since another user used another program to update some tables in remote SQL server, such as CUSTOMER, SHIPINFO, my off-line program need to update these new data once connect to domain.
Here is what I design in Pseudo code: (take CUSTOMER as example)
1) In remote SQL server, create a store procedure (sp_customer) to select all CUSTOMERS
2) In application, create a dataset (dst_customer) based on sp_customer
3) Insert all customers data which is in remote SQL server but not in local SQL server based on CUSTOMER_ID
I do not think this a smart way to do it.
We need to download multiple files from remote servers. It is a process that would take few hours to complete, since we are talking about images ~50kb each and more than 250.000 in total. Each images will downloaded, resized and then imported to SQL.DB, so we do not need to write files to the disk. Also the applications need to use network credentials, since it is behind ISA.
From your experience, what is the best method to implement this? Should we use WebClient or HttpSockets? Should we use Async methods or Threads ? How can we implement for example 5 simultaneously download to achieve better speed, since we may getting files from many different servers at once?
Can we upload and download files from remote servers through code without using FTP?

View 2 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?

After 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?

Response.Redirect(fullpath)
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.End();

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 RepliesI 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 have a full working web site that i ported to a new hosting company. In some pages i have links to PDF on the server (they do exist!) On the old server no problem. On the new one when user clicks on the link : error 404 file does not exist.. Should i look in the web.config ? i don't know where to start
