BOOL GetFile( LPCTSTR pstrRemoteFile**, LPCTSTR** pstrLocalFile**, BOOL** bFailIfExists = TRUE, DWORD dwAttributes = FILE_ATTRIBUTE_NORMAL, DWORD dwFlags = FTP_TRANSFER_TYPE_BINARY, DWORD dwContext = 1 );
Return Value
Nonzero if successful; otherwise 0. If the call fails, the Win32 function may be called to determine the cause of the error.
Parameters
pstrRemoteFile
A pointer to a null-terminated string containing the name of a file to retrieve from the FTP server.
pstrLocalFile
A pointer to a null-terminated string containing the name of the file to create on the local system.
bFailIfExists
Indicates whether the file name may already be used by an existing file. If the local file name already exists, and this parameter is TRUE, GetFile fails. Otherwise, GetFile will erase the existing copy of the file.
dwAttributes
Indicates the attributes of the file. This can be any combination of the following FILE_ATTRIBUTE_* flags.
FILE_ATTRIBUTE_ARCHIVE The file is an archive file. Applications use this attribute to mark files for backup or removal.
FILE_ATTRIBUTE_COMPRESSED The file or directory is compressed. For a file, compression means that all of the data in the file is compressed. For a directory, compression is the default for newly created files and subdirectories.
FILE_ATTRIBUTE_DIRECTORY The file is a directory.
FILE_ATTRIBUTE_NORMAL The file has no other attributes set. This attribute is valid only if used alone. All other file attributes override FILE_ATTRIBUTE_NORMAL:
FILE_ATTRIBUTE_HIDDEN The file is hidden. It is not to be included in an ordinary directory listing.
FILE_ATTRIBUTE_READONLY The file is read only. Applications can read the file but cannot write to it or delete it.
FILE_ATTRIBUTE_SYSTEM The file is part of or is used exclusively by the operating system.
FILE_ATTRIBUTE_TEMPORARY The file is being used for temporary storage. Applications should write to the file only if absolutely necessary. Most of the file’s data remains in memory without being flushed to the media because the file will soon be deleted.
dwFlags
Specifies the conditions under which the transfer occurs. This parameter can be any of the dwFlags values described in in the Platform SDK.
dwContext
The context identifier for the file retrieval. See Remarks for more information about dwContext.
Remarks
Call this member function to get a file from an FTP server and store it on the local machine.
GetFile is a high-level routine that handles all of the overhead associated with reading a file from an FTP server and storing it locally. Applications that only retrieve file data, or that require close control over the file transfer, should use OpenFile and CInternetFile::Read instead.
If dwFlags is FILE_TRANSFER_TYPE_ASCII, translation of file data also converts control and formatting characters to Windows equivalents. The default transfer is binary mode, where the file is downloaded in the same format as it is stored on the server.
Both pstrRemoteFile and pstrLocalFile can be either partially qualified filenames relative to the current directory or fully qualified. A backslash (\) or forward slash (/) can be used as the directory separator for either name. GetFile translates the directory name separators to the appropriate characters before they are used.
Override the dwContext default to set the context identifier to a value of your choosing. The context identifier is associated with this specific operation of the CFtpConnection object created by its CInternetSession object. The value is returned to CInternetSession::OnStatusCallback to provide status on the operation with which it is identified. See the article for more information about the context identifier.
