I’m using below code snippet to connect to a server using
wininet.dll in VBA but not able to connect to that. But when I try to connect to the server using WinSCP 5.15.1, it’s able to connect. And when I try to use 22.214.171.124 version of WinSCP, it shows error “Couldn’t agree a key exchange algorithm”.
It also shows login error when I try to connect it using
ftp command in
I’m wondering is it possible to connect to the server using
wininet.dll in VBA by fixing any thing.
Public Function checkFTPpath(ByVal ServerName, ByVal Username, ByVal password, ByVal remote_path) As Boolean Dim hostFile As String Dim INet As Long Dim INetConn As Long Dim RetVal As Long Dim Success As Boolean Success = False RetVal = False INet = InternetOpen("MyFTP Control", 1&, vbNullString, vbNullString, 0&) If INet > 0 Then INetConn = InternetConnect(INet, ServerName, 21, Username, password, 1&, 0&, 0&) If INetConn > 0 Then Success = FtpSetCurrentDirectory(INetConn, "/") Success = FtpSetCurrentDirectory(INetConn, remote_path) RetVal = InternetCloseHandle(INetConn) End If RetVal = InternetCloseHandle(INet) End If checkFTPpath = Success End Function
If you get “Couldn’t agree a key exchange algorithm” in WinSCP, it means that you are using SFTP protocol, not FTP. Wininet speaks FTP only, not SFTP.
You will have to use SFTP library. See SFTP upload in VBA.
