Best and easiest way to FTP files giving a progress status

I've read that one can't display a progress status using the Inet1 control.  If that's true, what's the best and easiest way to FTP files (put/get) and be able to display a status?  Some of the files I need to transfer can will be very large.

Sample code would be appreciated.

Thanks.

Thanks, but I've looked at both samples.  The first one doesn't provide an upload way and the second is quite complicated.

Any other suggestions?

Yes, you are right, it only shows download part.

You can always get down and dirty and use the Winsock Control.  You will need one for the control connection and one for the data connection.  Then you can manage EVERY aspect of your FTP session and upload/downloads with full resume capability and progress bars.

No, it is not a trivial matter. =)

...but there are tons of examples out there.

IDle_Mind:  Thanks, but I would like something simple.
Mike TomlinsonHigh School Computer Science, Computer Applications, and Mathematics TeachersCommented:
I wrote a generic ftp upload/download utility designed to be called from within other applications, with the ability to resume transfers and grab multiple files based upon a file mask.  It had active/passive modes and all the bells and whistles.

It ended up being over 3000 lines of code.

We were dealing with very large files (medical imaging files and database files) where status and resume capability was very important.

There are many examples of how to download a file with very few lines of code but they don't have error correction, status bars, or resume capability.

In short, if you want nice features, your going to have invest some time and use complicated code.

Good Luck,

Well, simply things have simple features...

Take a look at this excelent tutorial (not control but wininet API):
http://www.vbip.com/protocols/ftp/vb-ftp-client-library/tutorials/tutorial-01.asp
and subsequents chapters

The majority of the time, the files will be small and therefore, I don't think I need the resume capability.

I do need someway to communicate to the user that a download or upload is taking place.

I've search EE and read every article re:inet progress bar ftp.

Any additional suggestions/sample code would be greatly appreciated!

Thanks.

Then, If you don't need to show progress, a simple text in the caption (showing start/stop of both actions) in the main form would be enought.

Is it advisable to use Inet1 or should I consider connecting/FTPing a different way via VB?
halfondjAuthor Commented:
If I can, I would like to show a progress bar.

You can use the Inet control for ftp uploading, The way to do it

 download
       Inet1.URL = "ftp://ftp.private.com"
        Inet1.UserName = "George Washington"
        Inet1.Password = "no_lies"
        Inet1.Execute , "GET source.txt C:\target.txt"

upload
         Inet1.URL = "ftp://ftp.private.com"
        Inet1.UserName = "George Washington"
        Inet1.Password = "no_lies"
        Inet1.Execute , "CD gifs\thegifs"
        Inet1.Execute , "PUT C:\source.txt target.txt"
        Inet.Execute ,"CLOSE"

store the results in byte array

Regarding displaying progress, when you start to upload you know the file size, get the connectiong speed, and make your own calculation to display the progress bar.

halfondj,  Basker is showing an example code using inet control...!!
Also, it appears that you are opened to other ways to achieve that but as sonn as we post some diferent, you refuse them!

Basker,

"Regarding displaying progress, when you start to upload you know the file size, get the connectiong speed, and make your own calculation to display the progress bar."

Hate to bust your bubble Basker, but connection speeds can vary greatly from the time you start your transfer.  The internet is a wild place.  If the connection is terminated (gasp...that could never happen!), then you will happily go along updating progress while nothing is actually being sent/received.

Richie_Simonetti:  I asked which is a better way.  That was the key question.  Also, my original question re:adding a progress bar or similiar was not completely answered.  As you see, Idle_Mind pointed out a problem w/Basker's answer.

Since I don't have experience and it seems like you and others do, I'll ask again -- which is a better and more efficient way for performing FTP uploads/downloads, Inet1 or the more complicated way?

As soon as a solid answer is provided, I'll be more than happy to accept an answer.

Thanks again for your time!!

Alrighty halfondj,

I have searched high and low for ways to give a progress bar using the INET control while downloading AND uploading and haven't found anything.

There is a thread here which deals with the same topic:
http://www.experts-exchange.com/Programming/Programming_Languages/Visual_Basic/Q_20408606.html

So in my opinion, IF YOU MUST have progress bars then the INET control is NOT the way to go.
The code will be infinitely more complex, but use the Winsock Control.  Complexity is the price you pay for robustness.

However, you state:
"...which is a better and more efficient way for performing FTP uploads/downloads..."

INET is more efficient in the respect that the code is smaller.
Winsock is more efficient in that you have more control over the transfer.

As I said before:

"In short, if you want nice features, your going to have invest some time and use complicated code."

Thank you all for responding.  I just wanted to know from VB programmers more experienced than I am re:the more efficient way of performing FTP functions.

I had also researched the Internet re:this topic and couldn't come up w/anything re:Inet w/a progress bar, but I wanted to get other opinions re:other FTP implementations.

Thanks again!
