Which version are you on?

There’s a general-purpose HTTP client that’s been available since about 11.5.1

Where is the file coming from? Web site? Secure FTP site? Something else?

Actually that code can be used by character, gui, or webspeed. Give it a try. The authorization might need to go or be revised, but that code will do it. If you have that version of Progress.

Else, there is this really old C code I wrote (from 1999!) that will download anything. www.oehive.org/.../gethtml.c

Else you can write one using sockets. www.w3.org/.../rfc2616.html I've done it.

The DataDigger automatically downloads a file from GitHub to verify the version nr and to alert the user that a new version is available. It uses some windows functions to retrieve the file.

You can find the source here. It is easy to modify to get another file.

Better readable here

If you are windows there are plenty of 3rd party .net controls. We use WinSCP and it is very reliable.

So many answers!

Thank you all

We use OE 11.6.3 32bits, client-server, and no .Net

[mention:9e4ee96fac634b8f91b580e1fb4f7e71:e9ed411860ed4f2ba0265705b8793d05], I did't know about that http client.

So I just found this knowledgebase.progress.com/.../Is-there-an-HTTP-client-for-OpenEdge

I downloaded your example and when trying to execiute it receive this message and others.

Could not find class or interface OpenEdge.Net.HTTP.ClientBuilder. (12886)

So I guess we haven't some necessary licenses.

Brian K. Maher (maher),

the source is a website, specifically this url www.sunat.gob.pe/.../AgenRet_TXT.zip

It’s not a license thing :)

You need to add $DLC/gui/netlib/OpenEdge.Net.pl or $DLC/tty/netlib/OpenEdge.Net.pl to PROPATH (depending on what platfom you’re running on).

Thank you, Peter, I'll give a try now.

That did it really smoothly, [mention:9e4ee96fac634b8f91b580e1fb4f7e71:e9ed411860ed4f2ba0265705b8793d05] , thanks again!

[mention:05d4bf1e47934b44bc8ab65b8f317551:e9ed411860ed4f2ba0265705b8793d05], [mention:e666fffb14004b29b4bad87b731999a8:e9ed411860ed4f2ba0265705b8793d05] , I didn't try your solutions but probably later will do.

[mention:011caad85a5545659f1a1aaf22be3887:e9ed411860ed4f2ba0265705b8793d05] , here we use a commercial software called NetDrive2 but my guess is that maybe we can gradually replace it with WinSCP, if my tests go good.

Thank you all!

A while ago I used WinSCP for a project and it worked great - until it didn't. W/out support I couldn't figure out what the issue was.I don't remember the specifics beyond that you need to keep an eye on it and have a commercial, supported product lined up as a potential replacement "just in case"

Interesting...we have been using WinSCP for about 5 years with no issues at all. We send some pretty large files as well.

Posted by ezequielmontoya on 13-Feb-2018 06:28

Anyway WinSCP can't assign a Windows local drive letter to a remote SFTP one, and that's a "must" (unless I rewrite the connection part of a group of programs that are working fine).

That's why we chose NetDrive2, I remember now.
