I've put a FileUpload control onto my form. When client browses for a file and selects one I want to use that file as an attachment to my mail message. For this purpose I write:
Attachment attachment = new Attachment(fileUpload1.FileName);
mail.Attachments.Add(attachment);
I get an error that says:"Could not find file 'C:\Windows\SysWOW64\inetsrv\Water lilies.jpg'." The thing is the path to the file is different from the path in the client. How can I attach a file that is on the client's machine to a mail message?
Have a look at this http://imar.spaanjaars.com/412/sending-attachments-directly-from-a-fileupload-control
Server.MapPath should fix your problem.
Attachment attachment = new Attachment(Server.MapPath(fileUpload1.FileName));
The FileName property gives you just that - the name of the file, no path included. You're seeing inetsrv in the path because that's IIS' working directory. You will probably want to utilize the PostedFile property, which will handle saving for you:

I have a web page that is displaying a PDF file with the following code:
Response.Clear();
strFilePath = Server.HtmlDecode(Request.QueryString["filename"]);
Response.ContentType = "application/pdf";
Response.WriteFile(strFilePath);
The filename got from Server.HtmlDecode() is "\FileServer\shared\faxqueue\fax.pdf"
However an exception is thrown for directory not found and it says that it cant find the file. It also says in the exception that it is looking for: "C:[Website Root Folder]\FileServer\shared\faxqueue\fax.pdf"
This means that it has appended the filename given to the folder where the website code is located.
How can I stop it from using the website root?
Thanks
That is true because you ask it to do so.
It is a bad idea to pass in the direct file name using the query parameters.
You can of course create a direct path to the file you are using instead of this relative path:
string absolutePath = Path.Combine(#"C:\yourRootFolder", strFilePath);
Response.WriteFile(absolutePath);
But as said, I warn you for the security risks! You have to grant the IIS application pool user access to the folder you specify here. Your files can be easily hijacked by passing in something like:
..\..\..\Windows\anysecurefile.txt
I am developing a .NET intranet site which will enable the user to see a list of files (file details stored in DB) and link to the actual PDF/XML/XLS and open it... kind of like a table of contents for the network.
During data entry, the user enters various data about a document, then browses to the file on the network and selects it using the asp:FileUpload. The codebehind then saves the network path to the DB. There is alot of overhead here because i'm sending the file to the server but never use it.
Everything has been working fine until someone tries to use a large PDF file then I get the dreaded MAXIMUM REQUEST LENGTH EXCEEDED error... So I'm trying to find a solution here... I do not need the actual file.. just the path and filename.
I know not all browsers send the full path but our systems have older browsers so everything is working fine now, but will probably break soon.. which is another reason to find a different solution.
I've looked into Javascript to pull the path but that won't work...
Any other ideas? Other ways to just grab the path and filename? (besides manually typing it in to a Text field)
Thanks,
Todd.
This may help too
How to get the full path of a file from asp: file upload?
string filename = Path.GetFileName(FileUpload1.FileName);//file name
string path= Server.MapPath(filename);//path
I have a ASP.net page which writes a file to the local disk.
I want to present the user a Save File dialog box and allow him to set the path to the folder.
I know code like below can be used;
Response.Clear();
Response.ContentType = "text/csv";
Response.AddHeader( "Content-Disposition", "attachment;filename=\"report.csv\"" );
// write your CSV data to Response.OutputStream here
Response.End();
But it fixes filepath.
I need to capture the filepath that the user selects.
Is that possible in ASP.net?
Thanks.
it does not work like that from a web page, you have to initiate the download suggestiong a target file name then the user can override your suggested file name and select any folder or filename he likes and your content will be saved in that location.
you do nothing with a local path which only makes sense on the client machine on the server side of ASP.NET application.
I need to capture the filepath that the user selects. Is that possible
No. Your web server presents a file to the client, where the client has the option to save this file.
In what way would the path the client saves this file be interesting to the server?
I am using Fileupload control to upload file. I am displaying the selected file icon(with achor tag) with file name. if click the icon i want to open the selected file in a new window.
How to take the selected file path from the fileupload control.
Nathiya,
Do you want to open the file BEFORE it is uploaded to the server?
If the file was already uploaded to the server, then you know the file's path since you passed it to the FileUpload1.SaveAs() method.
If you want it before (e.g. someone clicked on the browse button and choose a file but did not upload it to the server) - Then this is not possible as the file is still on the user's local computer (you can't show files that are on the user's computer, only files that are on your server).
What i came to know from the search is it is not possible
As it leads to privacy breach and security breach
Please check this Get Full File path
FileUpload1.FileName will give you the name of a file on a client.
EDIT : As per the comment. You should first upload the file to your server. Then use the path (the url to the file) to set as the href value of an achor tag.
I need to give an option to user in jsp to choose a folder where he can save/download a file. Please help me on the same.
the text input="file" will give the file chooser but i need the directory chooser
HTTP doesn't allow you to specify (server side) where a file is downloaded to - this is not a jsp specific thing.
If you need to this then you'd need to provide an embedable application (javascript, java, flash, vbscript...) which is allowed to operate outside the browser sandbox and implements its own network client for retrieving the file. Which is far from an ideal solution.
You can force the download to use a specific name via the content disposition header.
the text input="file" will give the file chooser
..but that's for uploads - not downloads.
You can't set folder location at client machine of downloaded file using JSP/Servlet. If you want to add folder chooser feature then you have to develop an applet. You may use JFileChooser to allow user to select a folder and java.net.URL and java.net.URLConnection to download a file.
Most browsers will automatically download a file that the browser doesn't render, so it's just a link...! For example, if it's a zip file, just add it as any old "a link" in your code. When the user clicks , the download/save dialog will be launched ....
The "save/download" feature is a client issue -remember the web developers job is to provide content- it's the browser that decides how to deal with the content.
The key is the Content-Disposition header. Its value has to be set to attachment to force a Save As dialogue. You can do this job in a servlet. Just let your link URL point to a file servlet like so
download filename.ext
Then, in the file servlet, which is for the above example to be mapped on an URL pattern of /fileservlet/*, do the following:
String filename = URLDecoder.decode(request.getPathInfo().substring(1), "UTF-8");
response.setHeader("Content-Type", getServletContext().getMimeType(filename));
response.setHeader("Content-Disposition", "attachment;filename=\"" + filename + "\"");
// Now get an InputStream of the file and write it to OutputStream of response.
