VBA将文件上传到FTP

Question

我正在使用https://analystcave.com/vba-downloading-files-from-ftp-using-vba/中的以下代码将文件从本地驱动器传输到FTP：

Sub TestDownload
  FtpDownload "//Download/text file.txt", "C:\text file.txt", _
              "192.168.0.100", 21, "username", "password"
End Sub

Private Const FTP_TRANSFER_TYPE_UNKNOWN     As Long = 0
Private Const INTERNET_FLAG_RELOAD          As Long = &H80000000

Private Declare Function InternetOpenA Lib "wininet.dll" ( _
    ByVal sAgent As String, _
    ByVal lAccessType As Long, _
    ByVal sProxyName As String, _
    ByVal sProxyBypass As String, _
    ByVal lFlags As Long) As Long

Private Declare Function InternetConnectA Lib "wininet.dll" ( _
    ByVal hInternetSession As Long, _
    ByVal sServerName As String, _
    ByVal nServerPort As Long, _
    ByVal sUsername As String, _
    ByVal sPassword As String, _
    ByVal lService As Long, _
    ByVal lFlags As Long, _
    ByVal lcontext As Long) As Long

Private Declare Function FtpPutFileA _
   Lib "wininet.dll" _
 _
       (ByVal hFtpSession As Long, _
        ByVal lpszLocalFile As String, _
        ByVal lpszRemoteFile As String, _
        ByVal dwFlags As Long, _
        ByVal dwContext As Long) As Boolean

Private Declare Function InternetCloseHandle Lib "wininet" ( _
    ByVal hInet As Long) As Long

Sub FtpUpload(ByVal strLocalFile As String, ByVal strRemoteFile As String, ByVal strHost As String, ByVal lngPort As Long, ByVal strUser As String, ByVal strPass As String)
    Dim hOpen   As Long
    Dim hConn   As Long

    hOpen = InternetOpenA("FTPGET", 1, vbNullString, vbNullString, 1)
    hConn = InternetConnectA(hOpen, strHost, lngPort, strUser, strPass, 1, 0, 2)

    If FtpPutFileA(hConn, strLocalFile, strRemoteFile, FTP_TRANSFER_TYPE_UNKNOWN Or INTERNET_FLAG_RELOAD, 0) Then
        Debug.Print "Success"
    Else
        Debug.Print "Fail"
    End If

    'Close connections
    InternetCloseHandle hConn
    InternetCloseHandle hOpen

End Sub

宏卡在FtpPutFileA上，它处理了很长时间，最后以没有消息和文件传输的方式结束执行。

您是否知道为什么它不起作用或如何正确配置？

我使用与示例中相同的路径符号。
