Hi,

Downloaded files from one of our operators are always empty. I have tried active/passive modes, GET/MGET, ascii or binary to no avail. What is curios is that I can download the files from command prompt!

Currently I use ChilkatAx-9.5.0-win32.dll version 9.5.0.64.

Has anybody else had the same problem?

Thanks,

Dan

Here is a part of the dump file created (older dll):

Yes, this release works, thank you.

Try this new build:

32-bit Download: http://chilkatdownload.com/prerelease/chilkatax-9.5.0-win32.zip
64-bit Download: http://chilkatdownload.com/prerelease/chilkatax-9.5.0-x64.zip

Also, set the ftp.AutoGetSizeForProgress property = 1 to force the Ftp2 object to get the file size prior to downloading.

This FTP server seems to be a liar. ;) It's responding with this message:

RETR_reply: 150 ASCII data connection for testi-0398 (10.231.32.220,63602) (0 bytes).

Chilkat sees the "(0 bytes)" in the reply and believes it. Setting the AutoGetSizeForProgress, in conjunction with using the new build, should make Chilkat ignore the "(0 bytes)" response.

Didn't work :( MGetFiles brings all the files (zero length) and GetFile catches the error. As before, using active or passive connection didn't help. GetSizeByName does return the correct file size!
