Web Forms :: Data Getting Corrupted While Uploading Using FtpWebRequest?
Dec 25, 2010I am using :
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader("testfile.txt");
byte [] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();

Sharepoint - Downloaded Files Corrupted?
Aug 5, 2010I have written the following code to download a file from sharepoint. The downloded file works fine in only some machines. For others, it says that the file is corrupted. The issue is for MS Office and image files, however the PDF is not having any issues. We have identified the issue of corruption as due to the addition of a hexadecimal number at the top of the file contents. When it is removed, the file gets opened correctly. The hexadecimal character has been traced out to be representing the file size in bytes. Why this is happening only in some machines and how can we fix it?
private void DownloadFile()
{
SPListItem item = GetFileFromSharepoint();

Httpresponse - Why Are .docx Files Being Corrupted When Downloading From A Webpage
Mar 19, 2010I have this following code for bringing page attachments to the user:
[code]...
The problem is that all supported files works properly (jpg, gif, png, pdf, doc, etc), but .docx files, when downloaded, are corrupted and they need to be fixed by Office in order to be opened.
At first I didn't know if the problem was at uncompressing the zip file that contained the .docx, so instead of putting the output file only in the response, I saved it first, and the file opened successfully, so I know the problem should be at response writing.
Web Forms :: Uploading Multiple Files In 1.1?
Sep 23, 2010I am trying to make a web application which copies the existing functionality of a windows forms application using Visual Studio 2003. This windows application takes multiple (I am talking at least 30) text files and joins them together into one text file which can then be feed into a Mainframe system in the correct format. I have written web applications before that uploads images and pdfs but the key thing is it was always only one or two files at a time, so this was easy to do with the HTML fileupload control.
What I want to do is to be able to open a directory on the local computer and either automatically, or give the user the chance to multi select (I dont think this is possible) all of the 30 or so files they wish to upload. Once its been uploaded I can do the processing to join the files and create my new one etc. All the examples I have seen on the web, you have to select the files one by one to add to a list box and then they can all be uploaded but this wont be acceptable to my users...
Web Forms :: Uploading Files From One Site To Another?
Aug 24, 2010I need to upload files from one site to another and I thought about using the WebClient class and FileUpload method from the System.Net namespace. I read the MSDN documentation and it seems an easy task to achieve but something is going on wrong. For now, I am only testing with the following simple code to upload a file to a test web server in our office which uses HTTP port 8080 instead of 80:
[Code]....
The code above issues the following exception: "The remote server returned an error: (404) No Found." I have made sure that both paths are correct.
Also, does the UploadFile method saves the file physically in the hard disk (I suppose so) or does it load it into the server's memory?

Web Forms :: Uploading Files And Editing Them On One Page?
Jan 23, 2010I have one page that has a FileUpload control with a "Upload Photo" button and underneath that is a ListView control. I would like for the user to be able to browse for a photo and when they click the "Upload Photo" button, that photo displays, along with text boxes that are linked to my database (title, description, photodate) in the listview. The user can then repeat the uploading so that the user can upload as many photos as they want and they show up in the listview (all of them). After the user has uploaded all the photos he wants and has filled out all the information into the boxes of the corresponding photo, the user will then click a button ("Publish") the will publish all the photos that are in the listview.
How would I go about doing this?
