    Directory Working directory on the server.
    FileStructure File structure to be used for subsequent file transfers.
    Listing Object containing results from the last use of the List method or the NameList method.
    LocalAddress When the State property is tcpConnected, LocalAddress returns the address of the local host in dot notation (for example, nnn.nnn.nnn.nnn). When not connected, it returns an empty string.
    LocalDataPort Gets or sets a string used to restrict the local data port to a value or range compatible with your firewall.
    LocalPort When the State property is tcpConnected, LocalPort returns the port number that the socket is bound to. When not connected, it returns 0.
    Passive Indicates how the data connection is formed.
    Protocol Specifies the security protocol used.
    ProxyHost Specifies the name or address of the proxy server that requests are to be routed through.
    ProxyPassword Password to be sent on all requests through a proxy server that requires authentication.
    ProxyPort Specifies the port used by proxy server that requests are to be routed through.

    Code Example

    How easy is the FTP ActiveX component to use? Check out the following VB example below, which demonstrates a simple file transfer.

     

    Private Sub DoSecureLogin()
    ' The FTP server in this example is using Explicit SSL
    Ftp1.Authentication = atExplicitNormal ' Perform all checks in the Authenticate event.
    Ftp1.Protocol = secureAuto ' Login to the server. Security will be negotiated first.
    Ftp1.Login "server", "test", "password", , 21 ' Success! SSL connection established. Get help on the STOR
    ' command (just to test the SSL connection)
    Dim Response As String
    Ftp1.Help Response, "STOR" ' Print the response.
    Debug.Print (Response) ' Logout
    Ftp1.Logout
    End Sub

    Private Sub Ftp1_Authenticate(ByVal RemoteCertificate As DartFtpCtl.ICertificate, ByVal TrustedRoot As Boolean,
    ByVal ValidDate As Boolean, ByVal ValidSignature As Boolean, Valid As Boolean)
    Dim Msg As String
    ' Check various parts of the certificate to give the user a chance
    ' cancel if desired.
    If Not Valid Then
    If Not ValidDate And IgnoreDate = False Then Msg = Msg + "- Certificate date is invalid" + vbCrLf
    If Not TrustedRoot And IgnoreRoot = False Then Msg = Msg + "- Certificate Authority is not trusted" + vbCrLf
    If Not ValidSignature Then Msg = Msg + "- Certificate does not contain a valid signature" + vbCrLf
    End If

    If DoHostNameCheck And IgnoreHost = False Then
    If RemoteCertificate.IssuedTo <> Host Then
    Valid = False
    Msg = Msg + "- The name on the security certificate does not match the name of the site" + vbCrLf
    End If
    End If

    If Msg <> "" Then
    Msg = "The following conditions are true:" + vbCrLf + vbCrLf + Msg + vbCrLf + vbCrLf
    Msg = Msg + "Do you still wish to authenticate?"
    If MsgBox(Msg, vbYesNo + vbExclamation, "Security Alert") = vbYes Then
    DoHostNameCheck = False
