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 two tasks to accomplish. There are several pdf files (invoices) sitting in web server. My tasks are 1) enabling Olga to download multiple invoices into her local computer WITHOUT prompting any dialog box. 2) printing these files then automatically by default local printer from her desktop computer. How is possible this? She has birthday soon. No gift could be better than this solution as she has to open each pdf separately and hit print button about 40 times a day.

View 5 RepliesI am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL. Is there a way to secure files to have access by just the owner and no body else "may be website administrator also will have access"
View 3 RepliesFor a church website I'm managing, there is a need to place audio files (sermons) on the website. There will be two categories of audio files; one will be a sample size of the audio file, around 5 minutes in length. The other will be the full-length of the sermon (30-50 +/- minutes).
I have decided the best setup would be to place the audio files on the server. I would then store the audio information, as well as the path to the audio file, in a database. I had thought about placing the audio files in the database as a BLOB, but it seemed inefficient. My concern, is with tools like Mozillza plug-in "Download Helper" , it is so easy to simply grab the media files off the server. This would not be a big deal, except we want to sell the full-length audio files. I am running ASP.NET 3.5 on IIS 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 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 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.

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.

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 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

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.

<div align="center" style="margin-top: 13px;">
<asp:Image runat ="server" ID="imgDownload" src="Images/ajax-loader.gif" alt="" /> <br />

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:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<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.

Is there something I need to do just for IE?
Also, it works fine in Opera and Firefox. So just IE...
My customer wants me to display a button on a dynamically generated web page that will allow the user to print the page in pdf format. Is there a good way to do this? I looked briefly at iTextSharp, but it seems I would have create an html version of the page to give it as a string. Is there any way to convet the existing page? I know there are third party tools that will do this, but like most everyone else, we're somewhat cash strapped. Are there any good tools that are free or inexpensive? Or better yet a native way to do it?

I want to know two things about ASP.NET MVC2 that I've researched from Google but still confusing. Hope I can find clear and clean answer here.
First, how to upload a file to server with custom file path. (Eg. to /Content/Files)
Second, how to download that file, since the url has applied URL Rounting, how to map to them?
In my ASP.Net page, I allow users to download files from the server. If the file is of even a moderate size (does it with a 40 meg file, for example), when downloading, it fails with the error message:
"Insufficient system resources exist to complete the requested service".
I've checked out the server, and it's quiet (CPU, RAM, Hard Drive, Task Manager Processes, etc all very low in their numbers).
I've run the code from several client machines and I'm getting this error message no matter where I run it from.
