Hi,
Checking for the existence of a directory (or, indeed, a file).
I know the client gets a 30018 error and that this goes to the 'Done' event, but what _actually_ recieves this error? What can I query, in my IF statement, to determine that the result was a null directory? A code example would be nice, since I cannot seem to find one.

Hi Daniel,
I assume you are using Blocking mode. In that case, you can simply ignore exceptions in your code, and check LastError immediately after the method executes.
I.e:
[code]On Error Resume Next
wodSftp1.RealPath( / )
if wodSftp1.LastError = 0 then
'Do something
else
'do something else
End if[/code]
Can you try something like that?

Nice work, thanks. I'll give it a shot. LastError = 0 equates to success, I take it?

Daniel,
Yes. When 0 is indicated for error, that means that there was none, and method executed correctly.

Okay. great. In fact, since it's a utility method I can just return the result from wodSftp1.LastError = 0 ... except Visual Studio is now complaining that operator '=' is not defined for system exceptions.

Daniel,
You're using wodSFTP.Net or wodSFTP?
If you're using .Net, why don't you simply try using try...catch statements to catch exception on certain method?

Ah, right. Something like:
Try
wodSFTP.RemotePath = strDirectory
Return True
Catch
Return False
End Try
I suppose it's just that deliberately testing for failure, and then working forwards from an assumption as to why it failed, seems a bit counter-intuitive, but I guess there's only so much information that can be gained from looking down a secure pipe, and trying to interpret the messages that come back.

Daniel,
Please note that setting RemotePath will never cause an exception. RemotePath doesn't send anything to server, but only sets property.
You need to actually call a method in order to send something to server.
As for errors/exception handling, any of these should work:
[code] Try
sftp1.ListDir( /home/weonlydo/ )
Catch ex As Exception
'An error occured, do something
End Try
Or:
On Error Resume Next
sftp1.ListDir( /home/weonlydo )
If sftp1.LastError.Message <> Nothing Then
'...
End If[/code]
Hope I helped.

Damba
...with WOD's excellent support I was able to bypass Winsock and focus on the task at hand...
Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.
...your service has been phenomenal. It's always quick and you are there when I need you.
Just thought you'd like to know that my gateway app with your SMTP Server component held the line against a DDOS attack today...
You have been great as far as offering support is concerned and has been extremely responsive to both support requests and suggestions for product enhancements.
May I say how nice it is to work with components so complete and self-explanatory that using them in my application is as instinctive as though I wrote them myself?
...I'm extremely impressed with the product, it represents excellent value for money...
The SFTP ocx is one of the finest pieces of programming I have seen. It worked out of the box...
