Ftp uploading with progress dialog or callback function
#1
This is for older QM versions. In QM 2.3.2.7 and later, use functions SetProgressDialog and/or SetProgressCallback.

Note 1. The first two must be member functions (use menu File -> New -> New Member Function).
Note 2. Don't click http://Ftp.FilePutWithProgress. It is not a link. It was added by the forum software because begins with ftp.

07/04/2007
1. Fixed bug that prevented uploading multiple files on single connection.
2. ftpfile now is optional.
3. ifexists and ascii arguments joined into single flags argument.

function# $localfile [$ftpfile] [flags]

;Uploads localfile to ftp server. The same as Ftp.FilePutWithCallback, but shows progress dialog.
;Returns 1 on success, -1 on Cancel. On failure returns 0.


;See also: <Ftp.FilePutWithCallback>

;EXAMPLE
;Ftp f.Connect("ftp.mysite.com" "user" "password")
;f.DirSet("public_html")
;if(!f.FilePutWithProgress("$desktop$\test.exe" "" 3)) mes- "failed"

function# $localfile [$ftpfile] [flags] [fa] [fparam] ;;flags: 1 fail if exists, 2 don't check if exists, 3 msgbox if exists, 4 ascii

;Uploads localfile to ftp server. Similar to Ftp.FilePut, but here you can use a callback function.
;Returns 1 on success, -1 on cancel (if callback function returns 1). On failure returns 0.


;localfile - file to upload.
;ftpfile - destination file. If "", gets filename from localfile.
;flags:
;;;0-3 - what to do if the file already exists: 0 delete, 1 fail, 2 don't check (faster), 3 message box.
;;;4 - use ASCII mode. By default, uses binary mode.
;fa - address of callback function that will be called repeatedly while uploading. Can be used to show progress.
;;;function# nbAll nbRead fparam
;;;Arguments:
;;;;;nbAll - file size.
;;;;;nbRead - the number of bytes uploaded so far.
;;;Return value: 0 continue, 1 cancel.
;fparam - some value to pass to the callback function.
