FTP error from VB using WinInet API

Hello,

Tech: VB, IIS, WinInet API

I am implemeting FTP Asynchronously using WinInet dll. But sometimes I am receiving a error either sending files or retriving files.

The error number is 12031 (retrieved from Err.LastDLLError) and the Error documentation in the microsoft site says "The connection with the server has been reset".

Can you pls. tell me what does that error means? Is there a way to fix the above error?

Thanks.

Did you see these articles:

INFO: Using WinInet APIs Asynchronously Within Visual Basic (Q189850)
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q189850

Also:
Win32 Internet HTTP Functions in Visual Basic
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwebtool/html/msdn_vbhttp.asp

and I quote:
<quote>
The WinInet API also provides FTP and Gopher functions; however, the WinInet SDK documentation indicates that these functions are best suited to asynchronous use, and Visual Basic requires third-party tools to use asynchronous functions and callbacks. Therefore, this article focuses on HTTP functions, which can safely be called synchronously. (For a look at how you would use the FTP functions asynchronously using Visual C++®, please refer to Robert Coleridge's article, Advanced FTP: Teaching Fido to Phetch.

I did see the articles.

The problem now is, it runs for most of the times but sometime it gives errors. Any suggestions are welcomed

Thanks.

No idea.  I gave up attempting to write it asynchronously and instead came up with a synchronous solution.  In any case, there are far better commercial products that are more robust than anything you or I could devise.  In my case, I had some extra time on my hands and welcomed the challenge.  But I would never recommend it for anything "mission critical".

Good luck,
Anthony
