TNMFTP  white lines in textfile

Hi guys (girls),
I'm working with the TNMFTP component with which I download TXT and JPG files.
This works.

Problem :
If I load a TXT file and read it right after I downloaded it
x : 'filename.txt';
ftp : tnmftp;
list : tstringlist;

ftp.connect;
ftp.download (x,x);
list.loadfromfile(x);
ftp.disconnect;

the text file contains
1 line of text,
1 white line
1 line of text
1 white line
etc...

however, if I load the textfile in notepad afterwards, it seems to be fine, and i can use it in any program without any problem.

Basically the same happens for JPG, only this results in a picture that is totally f*cked, pardon my frech :-)

Why is this happening, and how can I prevent it from happening ?

Tom,

Hello,
I think this may be a unix to win problem
conversion.
Try to use the function AdjustLineBreaks(const S: string): string;
on each of the lines you get.

Or maybe it's a problem of ftp mode ?
are you working in binary or in ascii ?
if you are using one, try the other.

Just a wild stab in the dark but have you tried using the mode method of the NMFTP component to be something other than MODE_ASCII?

Neil is 99% correct (%1 chance of error, recount needed) all you do is this....

nmftp1.Mode(MODE_IMAGE);

Put that JUST before u download / upload.....

hi guys,

tnx for all the info,
jeurk's answer lead me to a correct solution,
apparently there are 3 modes to choose from in TNMFTP
MODE_ASCII
MODE_BYTE
MODE_IMAGE

first i tried BYTE, which apparently was not supported by the server (unrecognised type error), then I tried the MODE_IMAGE which worked fine for my text files, as well as for my images,so, i'm accepting jeurk's comment as an answer.

Once more tnx for the help,

Tom,
