Check if ftp file exists

[Giordano Bruno]

I have this code from MrExcel which used to work well until the http site closed.

<font face=Courier New><SPAN style="color:#00007F">Function</SPAN> FileExistsURL(<SPAN style="color:#00007F">ByVal</SPAN> URL <SPAN style="color:#00007F">As</SPAN> <SPAN style="color:#00007F">String</SPAN>) <SPAN style="color:#00007F">As</SPAN> <SPAN style="color:#00007F">Boolean</SPAN><br><SPAN style="color:#007F00">'> Supplied by Juan Pablo Gonzalez</SPAN><br><SPAN style="color:#00007F">Dim</SPAN> objXmlftp <SPAN style="color:#00007F">As</SPAN> <SPAN style="color:#00007F">Object</SPAN><br><br><SPAN style="color:#00007F">Set</SPAN> objXmlftp = CreateObject("MSXML2.XMLftp")<br><br>objXmlftp.Open "HEAD", URL, <SPAN style="color:#00007F">False</SPAN><br><SPAN style="color:#00007F">On</SPAN> <SPAN style="color:#00007F">Error</SPAN> <SPAN style="color:#00007F">GoTo</SPAN> ErrChk:<br>objXmlftp.send ""<br>FileExistsURL = objXmlftp.Status = 200<br><br><SPAN style="color:#00007F">Set</SPAN> objXmlftp = <SPAN style="color:#00007F">Nothing</SPAN><br><SPAN style="color:#00007F">Exit</SPAN> <SPAN style="color:#00007F">Function</SPAN><br>ErrChk:<br>FileExistsURL = <SPAN style="color:#00007F">False</SPAN><br><SPAN style="color:#00007F">Set</SPAN> objXmlftp = <SPAN style="color:#00007F">Nothing</SPAN><br><SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">Function</SPAN></FONT>

I'm trying to make it work with files kept in an ftp environment. The address is something like "ftp://ftp.acme.com/XYZ/acme.xls"

I would be grateful if someone could point me in the right direction.

Set objXmlftp = CreateObject("MSXML2.XMLftp")

So, is the MSXML2.XMLftp object a real object or did you make that up yourself ... ? Is your intention to find out if the file exists or to actually get it?

Thanks zenou,

Ultimately I want to open the file, but first I want to check if it exists.

I'm not sure what the MSXML stuff does, I was just trying to adapt it from the previous code.

Just try to get it. Failure will mean it doesn't exist or that it does but you can't get it. Either way, you don't have the file.

Here's a recent thread on FTP. My advice is to always do your transfer first "live" from the command line to be sure that you have the right commands, then to script it. Actually, my advice is to use a secure protocol (FTP is not secure and your password is sent plain text for all to see). But that's up to you.

Edit: Oops. Forget "MSXML2ftp". It doesn't exist, as far as I know. You can't access the services of a non-existent class. Nice try, though.

Hi Xenou,

I can get it manually, it requires a user name and a password. Dont know how to go about this via VBA though.

Thanks for that Xenou. Looks very helpful. I'll give it a try.
