_FTP_FileRead :: Number of bytes to read?

6 posts in this topic

#1 ·  Posted (edited)

Hi,

I was wondering how to use _FTP_FileRead, I need just one file to be read which has just one number in it on the first line. But I have no idea about what I should use for "number of bytes to read". The number in the file can vary, obviously.

Also, here's a quote from the helpfile:

Reads data from a handle opened by _FTP_FileOpen()

#Include <FTPEx.au3>
_FTP_FileRead($h_File, $dwNumberOfBytesToRead)

Parameters

$h_File Handle returned by _FTP_FileOpen() to the ftp file.

$dwNumberOfBytesToRead Number of bytes to read.

Any help would be appreciated :mellow:.

  • Estimate the maximum number of characters you are ever going to encounter in that first line.
  • Double it.
  • Use that as the number of bytes to be read.
  • Open/read your file in binary mode, and search for the first @CR character which should be your first line end delimiter.
  • All that you have read in before this is your string you are looking for.
  • If you need to convert the string to a number, that facility is also available.
Post some more code of what you have attempted, and the contents of the first two lines of the FTP source file, and we'll offer suggestions.

What do you mean by binary mode? Should I specify this when opening the file? I'm currently using the default.

$FTP_TRANSFER_TYPE_BINARY - Transfers the file using FTP's Image (Type I) transfer method. The file is transferred exactly as it exists with no changes. This is the default transfer method.

$FTP_TRANSFER_TYPE_UNKNOWN - Defaults to $FTP_TRANSFER_TYPE_BINARY.

$INTERNET_FLAG_TRANSFER_ASCII - Transfers the file as ASCII.

$INTERNET_FLAG_TRANSFER_BINARY - Transfers the file as binary.

And if the number I need is the only thing in the file, why would I search for @CR? Wouldn't _FTP_FileRead just give me that number?

Variables used in that piece of my code are kind of scattered, sorry :mellow:.

Hmm my script still seems to be unable to read the file... it can be opened without any errors though.

This script is supposed to upload the file of which you have the path on the clipboard when Ctrl + Y is pressed.

It takes the FTP info from FTP.conf in the scriptdir, or from FTPsecure.conf, which is basically an encrypted version of FTP.conf.

Please also see "Help" from the tray icon for a more detailed explanation.

However, when checking the maximum allowed file size to transfer, which is written down in FTuP.size in the same directory the files get uploaded to, I encounter errors:

(1) MaxSize is always zero.

$MaxSize = Number(_FTP_FileRead($FtpFileOpen, _FTP_FileGetSize($FtpConnect,$FTPDir & "FTuP.size")))

(2) Even when changing If $FileSize > $MaxSize Then to If $FileSize < $MaxSize Then

I still get the "Couldn't put the file on the server, despite a succesful connection." error :mellow:.
