I am using VS 2005, VB.Net.  I need to connect to an FTP server and get a
list of files.  I plundered the following code from MSDN to accomplish this
task. It was part of a class called clsFTP:

Public Function GetFileList(ByVal sMask As String) As String()
        Dim cSocket As Socket
        Dim bytes As Int32
        Dim seperator As Char = ControlChars.Lf
        Dim mess() As String

        m_sMes = ""
        'Check if you are logged on to the FTP server.
        If (Not (m_bLoggedIn)) Then
            Login()
        End If

        cSocket = CreateDataSocket()
        'Send an FTP command,
        SendCommand("NLST " & sMask)

        If (Not (m_iRetValue = 150 Or m_iRetValue = 125)) Then
            MessageString = m_sReply
            Throw New IOException(m_sReply.Substring(4))
        End If

        m_sMes = ""
        Do While (True)
            Array.Clear(m_aBuffer, 0, m_aBuffer.Length)
            bytes = cSocket.Receive(m_aBuffer, m_aBuffer.Length, 0)
            m_sMes += ASCII.GetString(m_aBuffer, 0, bytes)
            ' Console.WriteLine(m_sMes)
            If (bytes < m_aBuffer.Length) Then
                Exit Do
            End If
        Loop

        mess = m_sMes.Split(seperator)
        cSocket.Close()
        ReadReply()

        If (m_iRetValue <> 226) Then
            MessageString = m_sReply
            Throw New IOException(m_sReply.Substring(4))
        End If

        Return mess
    End Function

I connect to the FTP server perfectly. The rest of the functions in that
class work great, such as download, upload, etc..  Sadly, GetFileList only
returns the first file unless I step through, then it returns everything I
have. If I put a break point at the Do While line, then run again, it
executes perfectly.  If I let it run, it gives me just the first file. The
mask I am using is also correct.

Any clues???  It is driving me insane. Does the code look tight?  I have
tried everything I know how.

Thanks,
Mike

I cannot post questions as "new question".

I am installing IIS on my win xp professional. However,  there is no IIS
listed in the "add/remove windows components". Anybody can help?

Thanks

Use a newsreader like outlook express.

XP doesn't support IIS.

Get a copy of Apache/Tomcat.

Correction.

XP Home doesn't support IIS.

Get a copy of Apache/Tomcat.

(Are you sure you have XP pro? Do you have the CD?)

Show quote Hide quote No, it does not look correct to me:

This is not good criteria to leave loop as cSocket.Receive does not have to
return exact number of bytes that was requested. It can return less. It will
return number of bytes currently available (buffered by the OS). In case you
run it in debug mode and stop in breakpoint, you are giving network some
time to transfer more bytes then m_aBuffer can hold, so Receive will fill
whole buffer.

'Do While (True)

Array.Clear(m_aBuffer, 0, m_aBuffer.Length)

bytes = cSocket.Receive(m_aBuffer, m_aBuffer.Length, 0)

m_sMes += ASCII.GetString(m_aBuffer, 0, bytes)

' Console.WriteLine(m_sMes)

'If (bytes < m_aBuffer.Length) Then

'Exit Do

'End If

'Loop



Commenting out the loop returned a perfect value.
