I would like to ftp a file from inside a vb.net program. I've looked on the web but have seen mostly reccommendations for third party components. I've sent e-mails from vb.net (in an asp.net applicaitons) so I figure there should be something similar (an ftp object for istance) that is already part of vb.net.

  Does anyone have any suggestions/code.

We had the same problem some months ago, but we chose to buy a component instead (the dart ftp.net component). Saved us a lot of time and frustration. Can handle asynchronous and synchronous ftp transfer. Didn't found some code to use and the lack of time and knowledge made us buy it.

Hello,

Here is a link to a complete guide on how to implement FTP within VB.NET. It's a tad complicated...but worth the effort.

cheers!

Sorry, forgot to post the link (duh)...

I thought someone might be interested in a REALLY simple solution I got this one off another message board:
   It got me going in minutes. I am curious as to why complicated solutions seem to be more popular than simpleones.

Just wondering if anyone has managed to get the really simple solution that fig000 posted working. I too am trying to implement ftp inside a VB.Net program, and had found those lines of code on the web too.

The InternetOpen and InternetConnect calls seem to be working (ie it doesn't return 0), but the FtpGetFile always returns False - its not getting the file. I have no idea why. Anyone else had any luck with this?

Hello,
you could also try several free ftp libraries found at www.codeproject.com. You could also try Rebex FTP.net component - it comes with a lot of samples (both vb.net and c#). It even includes WinForm ftp client similar to Windows Commander (aka Total Commander) with complete vb.net source code...

http://www.rebex.net/ftp.net/

The above method for FTPing files works like a charm. I created a nice little program that ftps to all my machines and pulls some files. I agree you should not use a brick to kill a fly if you don't need to.

To answer the problem about not getting the ftp file.. you should try using the command line ftp program in windows to debug.. try to replicate the same steps as you are doing in your program. Then at least can narrow down your problem.

Ok guys, I am also trying to use the code fig000 is using and i have the same problem as jazzart, did any one solve this, the ftp file isnot transferred for some reason ....

Can you send a code snippet.
