      (Unicode C++) ConnectFailReasonSee more FTP ExamplesThe ConnectFailReason property can be examined to determine the reason why the Connect method failed. The possible values are listed in the source code below:
 #include <CkFtp2W.h> void ChilkatSample(void) { // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkFtp2W ftp; ftp.put_Hostname(L"ftp.example.com"); ftp.put_Username(L"login"); ftp.put_Password(L"password"); // Connect and login to the FTP server. bool success = ftp.Connect(); if (success != true) { // The possible failure reasons are: // 0 = success // // Normal (non-TLS) sockets: // 1 = empty hostname // 2 = DNS lookup failed // 3 = DNS timeout // 4 = Aborted by application. // 5 = Internal failure. // 6 = Connect Timed Out // 7 = Connect Rejected (or failed for some other reason) // // SSL/TLS: // 100 = TLS internal error. // 101 = Failed to send client hello. // 102 = Unexpected handshake message. // 103 = Failed to read server hello. // 104 = No server certificate. // 105 = Unexpected TLS protocol version. // 106 = Server certificate verify failed (the server certificate is expired or the cert's signature verification failed). // 107 = Unacceptable TLS protocol version. // 109 = Failed to read handshake messages. // 110 = Failed to send client certificate handshake message. // 111 = Failed to send client key exchange handshake message. // 112 = Client certificate's private key not accessible. // 113 = Failed to send client cert verify handshake message. // 114 = Failed to send change cipher spec handshake message. // 115 = Failed to send finished handshake message. // 116 = Server's Finished message is invalid. // // FTP: // 200 = Connected, but failed to receive greeting from FTP server. // 201 = Failed to do AUTH TLS or AUTH SSL. // Protocol/Component: // 300 = asynch op in progress // 301 = login failure. int failReason = ftp.get_ConnectFailReason(); wprintf(L"connect fail reason = %d\n",failReason); wprintf(L"%s\n",ftp.lastErrorText()); return; } // .. }  |
