C# - Upload File Via FTP - Server Returned Error (550) File Is Unavailable, Cannot Find File?

Oct 31, 2009

I'm trying to upload a file via FTP from my local computer to an FTP server, which is also on my local computer at the moment. I've got this sub I'm calling:

Public Sub UploadFTPFile(ByVal ftpservername, ByVal fullfilepath, ByVal filename, ByVal username, ByVal password)Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential(username, password)
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

[Code]...

I'm running an FTP Server using Golder FTP Server, which is freeware. I think it's setup correctly because connecting to the FTP Server using the exact same string as above using Windows Explorer works great.

VS 2010 Getting A 505 File Unavailable Error?

Nov 16, 2011

so here's my code. I'm testing to see if a user exists on the server before I let them log in.

'Creates test file
Dim write As New StreamWriter("c:/test.ping")
write.Write("This is a test string used to log in a user.")
write.Close()

[Code]...

Dim mStream As Stream = mReq.GetRequestStream()Another strange thing: the streamwriter won't write to C:/test.ping. I changed it to E:/test.ping and it wrote (E is my Ext HDD) but I still got the same answer.I'm using Windows 7 Home Professional. On my old XP PC I got it to work but that was a while ago.

Error When Opening Text File - FileNotFoundException Was Unhandled - Could Not Find File At Xxx

Feb 15, 2012

I have a program that can save user's input into a text file and load it back, but whenever I try to open the file and exit without selecting the file I get an error.(if i select the file and open it i don't get any errors).

This is the code that handles text file loading:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
OpenFileDialog1.InitialDirectory = "C:"
OpenFileDialog1.Filter = "Text Files ONLY (*.txt) | *.txt"
OpenFileDialog1.ShowDialog()

[CODE]...

The error is :"FileNotFoundException was unhandled. Could not find file at xxx". also I would like to know how to make it so that the initial file name for file saving is today's date. I do not get any errors when I try to save the file.

.net - How Does File Upload Work On A Server

May 10, 2011

I have the following problem: I have a client who will upload an Excel file online. This Excel file will need to be imported to a database table, which I can do using the openrowset command. Once it has been imported, I can display the data using a GridView.

Now, I have referred [URL], but in both of them, the upload folder (destination) is hardcoded. How can I change this to reflect the file's destination to be on the server? And, once this is done, how can I then use openrowset to extract the contents of the Excel fie?

Additionally, how can I emulate the entire process on my machine before it is deployed?

XSD File To Upload Data To SQL Server Via DataAdapter?

Jun 2, 2009

I am wanting to use the TableAdapers and/or DataAdapters that are stored in an XSD file ("A DataSet for using data in your application") to

1) delete data from SQL Server

2) insert data from a dataset to SQL Server.

the XSD is to be stored as a file outside of the application so that the same code (this code i am having difficulty with) can be used to upload data from different excel files.

I created the XSD file in VS 2005 and "Configured" each table adapter to generate: Select statement, Update statement, Delete statement, table mapping, Fill method, Get method, and update method.

I am searching for some generic code that will execute the update statement and populate the database with the data in the data set.

How do i retrieve the TableAdapter and DataAdapter information from dsXSD (or the file dsLoadData.xsd)?

And then use the data, especially if relationships exist between tables defining a specific order for the tables to be loaded...

Do the SQL Statement need to be dynamically (at run time) written?[code]...

Creating A Web Application Which Is Going To Allow The User To Upload A Video File To The Server

Jun 7, 2010

I'm working on creating a web application which is going to allow the user to upload a video file to the server. Once the file is uploaded to the server, it's going to be converted to .flv and copied to another folder in the same directory. Since I'm doing this from a web app, I don't want to tie up the app with the conversion process. That is when I figured this might be a good time to try threading the conversion process... what do you think?

Currently, my process logic is this:

1) User presses the upload button.

2) A dummy record is created in the database for the file being uploaded.

3) Folders are created on the server to house the original video file and the converted video file.

4) The original is copied to the server.

5) Once the original is finished being copied, the app converts the original to .flv and saves it in another folder.

6) Information about the conversion process is stored in a .xml file

7) The dummy record is updated with real data

8) There is a redirect to a page that lets the user view the .flv file on the web
