Question

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

    clsRequest.KeepAlive = False

    ' read in file...
    Dim bFile() As Byte = System.IO.File.ReadAllBytes(fullfilepath)

    ' upload file...
    Dim clsStream As System.IO.Stream = _
        clsRequest.GetRequestStream()
    clsStream.Write(bFile, 0, bFile.Length)
    clsStream.Close()
    clsStream.Dispose()
End Sub

When calling the sub, I do it like this:

UploadFTPFile("192.168.1.3/Temp", selectedSoundFileLong, OpenFileDialog.SafeFileName, "", "")

In other words, in the Sub, this string:

DirectCast(System.Net.WebRequest.Create("ftp://" & ftpservername & "/" & filename), System.Net.FtpWebRequest)

, creates the following:

    DirectCast(System.Net.WebRequest.Create("ftp://192.168.1.3/Temp/test.mp3"), System.Net.FtpWebRequest)

And at this line in the sub:

        Dim clsStream As System.IO.Stream = _
        clsRequest.GetRequestStream()

This error occurs:

The remote server returned an error: (550) File unavailable

What could be the cause of this?
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.

Answer 1

are you sure there is no extra white space in the webRequest string? I believe you would get this error if the string happened to be like “ftp://192.168.1.3/ Temp/test.mp3″ Also, check to make sure you have the correct privileges to write to that server. Additionally, make sure you file is test.mp3 and not test.MP3.
