Notes:
hConnect (in) A handle returned from a call to InternetConnect.
fExpectResponse (in) A Boolean value that indicates whether the application expects a data connection to be established by the FTP server. This must be set to TRUE if a data connection is expected, or FALSE otherwise.
dwFlags(in) A parameter that can be set to one of the following values.
| Value | Meaning |
| FTP_TRANSFER_TYPE_ASCII | Transfers the file using the FTP ASCII (Type A) transfer method. Control and formatting data is converted to local equivalents. |
| FTP_TRANSFER_TYPE_BINARY | Transfers the file using the FTP Image (Type I) transfer method. The file is transferred exactly with no changes. This is the default transfer method. |
lpszCommand (in) A pointer to a string that contains the command to send to the FTP server.
dwContext (in) A pointer to a variable that contains an application-defined value used to identify the application context in callback operations.
phFtpCommand (out) A pointer to a handle that is created if a valid data socket is opened. The fExpectResponse parameter must be set to TRUE for phFtpCommand to be filled.
Return Values : Returns TRUE if successful, or FALSE otherwise. To get a specific error message, call GetLastError.
