When I'm trying to download a 50 MB file from a database (it is not an issue with a smaller file size), it stops in the middle sometimes and resumes again after a long time.
[Code].....
We have a very simple ASP.Net page for uploading a file to our webserver. The page has no controls - a client uses it to automatically send us a file each night.
On occasion, the file seems to not get to us, but the client reports that they have sent it.
We added some logging statements to the page, and discovered something quite odd. The page ceases to execute right in the middle of a log statement. No exceptions, just up and dies.
Here is the code-behind:
[code]....
I assume if there was a error in the transmission of the file that either an exception would be thrown from the reader.ReadToEnd() line. And if not an exception, I would expect the page processing to continue but that I may only receive part of the file (in which case it should log something).
The logging statement is only accessing a string variable, and it's inside a try-catch. NLog is the logging component we use, and we access that through the facade provided by the Simple Logging Facade project on Codeplex. So, we trust the logging component to be more or less bulletproof - we certainly don't see anything in our usage of it here that should be causing problems.
Why on earth could this page just up and stop processing like this?
The fact that we get a half-finished logging statement seems to point towards an error being swallowed in the logging system - but that just seems so unlikely - and we have NLog's internal logging on and it is not reporting any problems.
I am downloading a file from a remote location to my local machine. The paths I am using are saved in web.config and are in following format:
<add key="FileFolder" value="Files/"/>
<add key="LocalFileFolder" value="D:REAL" />
the code I am using to download is:
CreateDirectoryIfDoesNotExist();
WebClient webClient = new WebClient(); [code]...
When i deploy it on the server; and run my program, i get a message saying that download has completed successfully. But the problem is that the file is downloaded on the server machine in the filefolder (LocalFileFolder). I want it to be downloaded on the local machine. What is it that I am doing wrong?
I am currently developing an ASP.net application, where I generate a word document in server and I want to save it in client machine who access that feature with out user interactions. How can I download it and save it in client machine, using javascript?

I've looked all over the web for something that would show me how to do this but can't find it. I have a page that uploads information about an individual including a resume in the form of a doc docx or pdf. I can upload the file okay but I do not know how to, on another page, To download the file that was loaded to that person's row in the database. Here is the upload code

i have been trying to solve this for hours with no luck. i seem to be missing something fundamental.
i have a remote FTP server with a file called log.txt on it, i wish to allow web users to download this file to their local drive to a designated folder.
i have a function calling this sub i found on the web with the filename to download.when trying to run this code i get this error:
" Could not find a part of the path 'C: empFtpDownloadsFolderlog.txt'. "
[Code]....
if i replace this line:
[Code]....
i get no error but the file is not in the TempPath. (it shows it to be saved to "C:WindowsTEMPlog.txt" )
i have a feeling its being save on the server instead of my local drive.
I am downloading file from remote server in page load using content disposition. After downloading the file i am trying show some other controls in the page. But that controls are showing asp.net .

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 Replieswe are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.
Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?
We use this code to set the filename :
fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);
My requirement is client has to download files which were uploaded by employees. But if the file name contains a space, Mozilla Firefox use only the name up to the first white space and remaining name is truncated. Is it issue with mozilla firefox? if so how can i get rid of this. Important thing is in IE its working well.
View 2 RepliesI'm using the full-text feature on SQL Server 2008 RC2. Everything had been working well until today. I wanted to change the language for word breakers from Neutral to Slovakia. After I did that, I can't perform full-text search anymore. It simply give me no rows. I even deleted the old full-text catalog and created a new one and populated it, but it still gave no solutions. I tried to query dm_fts_index_keywords_by_document on my table and get only 1 row with a display term END OF FILE.
View 3 RepliesI am working on a http based (NOT Secure) Web Application. In this, I have provided a provision to add some appointment to the Client's outlook calendar. I am creating the .vcs file dynamically when clicked on a hyperlink. The code of generating .VCS file is:
string calendarFormat = GetVCSFormat();
Response.ContentType = "text/calendar";
Response.AppendHeader("content-disposition", "attachment; filename=MyCalendar.vcs");
Response.Write(calendarFormat);
Response.End();
It is working fine in all browsers except IE. It is giving me following error:Internet Explorer cannot download GenerateAppointment.aspx from server. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found.
I have a link button which the user clicks on it and will download a .PDF file into their PC.It is just a file for them to download.
Currently, I have the following code.
Response.Clear()
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=Savings Account eStatement.pdf")
Response.Charset = ""
Response.ContentType = "application/vnd.pdf"
Dim objSw As New StreamWriter("Savings Account eStatement.pdf")
objSw.Close()
lblMsg.Text = "Your file created successfully"
lblMsg.ForeColor = Color.Green
'Response.Output.Write(sw.ToString())
Response.Flush()
Response.End()
' Download the file
Response.Redirect("~/Savings Account eStatement.pdf")
Response.Flush()
Response.End()
Following on from my previous question...
The following code creates log files on a web server:
private void LogMessage(Message msg)
{
using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt"))
{
sw.WriteLine(msg.ToString());
}
}
The log files are linked to from an admin page on the web site:
foreach (FileInfo file in logDir.GetFiles())
{
Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>");
}
I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.
i am making a gridview in which textfield of password should match with the password stored in the database (table) .As soon as that happens, the file should be ready to download . now the problem is that the code is niether working nor showing any error, which is very sarcastic.
if (txtval.Text != null || txtval.Text !="")
{
if (txtval.Text == ds.Tables[0].Rows[0]["FilePassword"].ToString())
{
lblmessage.Text = "File has been downloaded successfully.";
WebClient fileReader = new WebClient();..........
I'm trying to write come code for users to download files, but the files are located above the webroot (e.g. c:downloads)
I've found some code online that allows me to download a file via a url parameter/argument which is perfect, but the files need to be located within the website structure.
<%@ Page language="vb" runat="server" explicit="true" strict="true" %><script language="vb" runat="server">Sub Page_Load(Sender As Object, E As EventArgs)Dim strRequest As String = Request.QueryString("file") '-- if something was passed to the file querystringIf strRequest <> "" Then 'get absolute path of the fileDim path As String = Server.MapPath(strRequest) 'get file object as FileInfoDim file As System.IO.FileInfo = New System.IO.FileInfo(path) '-- if the file exists on the serverIf file.Exists Then 'set appropriate headersResponse.Clear()Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)Response.AddHeader("Content-Length", file.Length.ToString())Response.ContentType = "application/octet-stream"Response.WriteFile(file.FullName)Response.End 'if file does not existElseResponse.Write("This file does not exist.")End If 'nothing in the URL as HTTP GETElseResponse.Write("Please provide a file to download.")End IfEnd Sub</script>

how this can be modified so that it can access files outside the webroot?
I'd like it so that I can create an href like: <a href="download.aspx?file=test.pdf">Download File</a> and then the code will download the file from c:downloads est.pdf
I have VB code that parses XML data from a webpage. Up until 2 days ago the XML data could be viewed right on the page and I could just grab the HTML source code to get the information. Now they have changed the page to a link button to download the XML file.
The problem is that when I click on the XML link I get the 'File Download Prompt' which asks me to run or save the file. I figured I could just save the file to temp directory and then open it up to parse it in my VB app but I can't figure out how to grab the file from the browser in my application.
I am trying to find a way to prevent a PDF from being printed or downloaded when view from web. Also, it is prefered that user cannot Print screen.
According to the required futures, it will cose a lot to create a desktop application from scratch.
I am thinking about converting those PDF files to Flash.
I have 4 checkboxes named(Laptop, Car, Phone, TV) and a button. when user checks one Car checkbox and clicks a button, car specifications pdf should be downloaded. Similarly when phone or laptop checkbox checked, relevant pdf's should be downloaded. For this i have written following code
[Code]....
This code is working well in VS2008 but has issues when run in localhost.
Issue --> Check one checkbox like chkPhone and click on button, the Phone pdf gets downloaded and uncheck chkPhone checkbox and check other one like chkCar and when clicked on button to download, getting following errors.
1. xml parsing error not well-formed --> this error is getting only in mozilla.

I have googled the issues and find the following sites[URL] For second issue i added the following line
System.Net.ServicePointManager.Expect100Continue = false;
but still sometimes iam getting the same error. Sometimes these errors raise after downloading 2 files and when tried to download 3rd one.
I wrote download excel file in my code. If I click download button I need show ajax-load image (pnlPopup panel). But it is not displaying. I think because of Some "Response" statements (see below code). Download working fine, but simultaniously I want show loader panel too.
<asp:Panel ID="pnlPopup" runat="server" visible="false">
<div align="center" style="margin-top: 13px;">
<asp:Image runat ="server" ID="imgDownload" src="Images/ajax-loader.gif" alt="" /> <br />
<span class="updateProgressMessage">downloading ...</span>

I have an export to excel functionality on my web application. WHen the user clicks the "Export to Excel" button, the file is created and it will ask the user to open it or save it to their local machine.
Since the file creation process takes a long time, I added the ajax update progress control. SO now, as soon as the user clicks the "Export to Excel" button, the progress bar image shows up, but after the file is created, I get the following error.
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.
I know that, if we use Response.write in the code behind, we get this error. But I have to use Response.Write because I am presenting the user with a prompt to save or open the newly created file. Is there any other way to do this?
The following is the aspx code.

<asp:UpdateProgress ID="UpdateProgress1" runat="server">

I'm downloading a file from my intranet site and on Chrome, it works as expected. But when I try it on IE, it crashes.
ASP.NET Code:
<a href="../nbd.exe">TEST</a></h2>
Is there something I need to do just for IE?
Also, it works fine in Opera and Firefox. So just IE...
