Hi,

I've got a VB6 program that has been doing fine on a different server, but when I switch to another server (both internal to my company, in theory set up identically), I cannot upload. I can download and enumerate directory contents fine; it's just the upload that fails.

One thing I spotted in the .lasterrortext was this:

StatusResponse:
  Request: FXP_OPEN
  StatusCode: 5
  StatusMessage: Invalid file attributes specified

I don't see anything I can set that tells it to not request certain attributes to be set, or for that matter what attributes it might be asking for, so I'm not sure what it's trying to do. If I use WinSCP in GUI mode I can easily drag the same file across local -> remote and it doesn't complain so it doesn't seem to be permissions-related.

I appreciate any help!

Great, that (ForceV3) worked. It's a "newer" server so I suppose it was configured differently even though of course they swear it's identical...

Thanks so much for the responses and for a great product.

Please post the full contents of the LastErrorText. It is especially important to know if you are using an older version of the component, in which case it's best to first download and use the very latest version and then re-test.

The "DllDate" line within the LastErrorText shows:

DllDate: May 25 2011

Which indicates an old version. Try downloading and testing with the latest version.

Okay, downloaded the most current on the site, and here's the only difference between the above and the new log (new <!, old !>). Still same net failure.

Hi again,

Anything further I can try to determine what the module is complaining about? I've got verbose on but perhaps there's a "more verbose" mode that would explain more?

You're still using an older version. The latest version is from April 2012. Your LastErrorText shows this:

Bizarre. I installed that last Thursday and can't think where I would have downloaded from but your site. I note that the current one has the version number in the name of the .msi, which the one I installed last week didn't. No matter, I just installed this one and still having the same error result. Here's the whole log this time:

I see that the SSH client and server decided to use v4 of the SFTP protocol. Check to see if using v3 of the SFTP protocol solves the problem. Do this by setting the sftp.ForceV3 property = 1 (Given that you are using the ActiveX, boolean properties are actually integers having the value 1 or 0)

If that doesn't work, then for testing purposes, try calling the sftp.OpenFile method with the access argument equal to "readWrite", and the createDisposition argument equal to "createTruncate".
