I am writing an ASP.NET web application.
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?

how to upload/Download maximum file size
View 4 RepliesI've always been required show download size next to the file hyperlink. Only the file in question is rebuilt everyday and the file size can change often. So needless to say the size has been wrong for months. I'm not going to update our site daily to display needless info.
instead of
<a href="file.xxx">click here to download (20mb)</a>
I'd prefer
<a href="file.xxx">click here to download [sizeof('file.xxx')]</a>
The best solution would be javascript based or similar.
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?

View 2 RepliesWith the ajax file uploader, would it be possible to check the size of the image before uploading?Currently, it uploads the file to the server and then lets me know that it's bigger than the limit size.
Is this possible to get the details like size, creationdate, modification date of a file hosted at some ftp server? I can download/upload files to ftp directory using ASP.Net but my requirment is to download the last modified file. So can we sort files of a ftp directory by modified date using ASP.Net code?

View 3 RepliesI have a text file with tab as delimiter. There are about 20 fields in the text file and the file size is about 150MB-200MB.
I need to filter out each row in the textfile based on its field criteria, For Eg: the i should ignore the particular row if the Field A is empty.
I know that by reading out the text file row by row it will be certainly slow.
how to read out the text file fast and also how to do the file processing for the read out text file?
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'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:
