I need to provide a way for the user to specify a path to a file on his machine on my intranet web application, and the ASP:FileUpload control provides a nice dialog to do that, however it also transfers the contents of the file over. Since I only need the file path and not the contents, is there another way to achieve this?
View 2 RepliesCan I upload files without having a fileupload control? I was looking at the HttpFileCollection class, but I believe that only works with the fileupload control.

I'm testing a very simple aspx page on Visual Studio's own ASP.NET Development Server(the local server). On the webpage there is a FileUpload control which can upload jpg file up to 2MB without problems. On uploading bigger files, the browser immidiately show "The web page cannot be displayed". It does not show any exception which really puzzles me. "The web page cannot be displayed" is normally caused by network problem, but in this case it's a local server and it can handle smaller jpg file fine. Whta's the problem here?
View 3 RepliesWe have a problem with some people working from home where when uploading 30-40mb (max upload is 50mb) they are timing out. Naturally when these people are on site they have no problems because of the network speed with have.

View 3 RepliesWe need to upload multiple files using ASP.Net in one go. One option is to use the ASP.Net FileUpload control but it seems that it can't upload multiple files in one go. Any other option or ASP.Net FileUpload control can do multiple uploads in one go with some tuning?
View 2 RepliesI'm trying to use an asp:FileUpload Control to allow users to upload files (.doc, .gif, .xls, .jpg) to a server that is outside of our DMZ and not the Web Server. We want to have the ability to look at these files for viruses, structure, etc prior to saving them into another directory that would allow access to outside users. From what I have read about this control is that it will allow for files to be uploaded to the web server. Can this control be used to upload files to a server other than the web server? If it can be done where should I look for this type of functionality or how do I force it to go to https:servernamefolder name (Where server name is not the web server)? Would I have to read the file then write it to the other server?
View 2 RepliesI'm building an ASP.NET UserControl where users of the website can upload several pictures at once. I'm doing it the old fashioned way by letting the user enter the amount of FileUpload controls wanted and then add them dynamically from C# to a asp:Panel control.
While this works, the values/files from the FileUpload isn't stored for when the user clicks the "Save" button. How exactly do I go about this problem?

In continuation to my previous research at this link : Security Risks or concerns with the use of FileUpload control of asp.net - how to Scan files during upload, also how to intimate user if file is virus affected and abort the operation.

View 1 RepliesIn my website,I have a home page in which by clicking on an image button,I get redirected to a different .apsx page .This page consists of a FileUpload control and 2 buttons(ATTACH,CANCEL).When a user selects/browses a file from his local machine and click ATTACH button,I display that file in a GRIDVIEW and also push the details of that file like Filename into a DATATABLE. The user in this way can browse multiple files and all of them are added to GridView and also pushed to DATATABLE.Now when the user clickes CANCEL button,I am sending the whole DATATABLE in a session object to the HOME page.Upon clicking SAVE button in the home page,the files in the DATATABLE must get stored in a physical location that I mention in the code. The problem that I am facing is that when I write
FileUpload fl=new FileUpload;
fl.SaveAs(dt["fileName"]);
The files are not at all getting saved in the location. However If I pass the FileUpload control using Session from the second page,
FileUpload fl=(FileUpload)Session["FileUpload"]
The files are getting saved with the correct filenames but the content of all the files consists of the content of the latest uploaded file.I know what the problem is but unable to get a solution. My Requirement is to save the files in a physical path only after clicking the Save button in the home page.

* If you are unable to load any pages, check your computer's network connection.
