I am happy that it works now And thanks for the offer.

Please download QuickOPC 5.34.274.1 (or later) from www.opclabs.com/products/quickopc/downloads .

Then re-install it, rebuild your project with new assemblies, and re-test.

As indicated by email, I have reproduced the problem. First diagnostic results show that the server's SetFilter(...) function is returning E_NOTIMPL, which is not really allowed for a compliant server, but we can try some workaround.

I have changed the client code so that when you do not specify a filter (i.e. there is no filtering - a "pass-through"), we will not even call the SetFilter(...) in the server.

This works well in the sense that the event with "Not implemented" is no longer generated. I cannot tell whether the final goal - i.e. receiving proper events from the server - is achieved, because the server does not appear to be generating events right now (I think this is because it is not actually configured to do anything at the moment). The are not coming to Matrikon OPC Explorer either.

The issue right now is the delivery. I have started the automated build process, which, however, takes quite a long time (hours). If that succeeds, I will post a new build as the public download, and inform you here. If this is not finished in time, I will send you a ZIP file of updated assemblies only, and notify you by email. I will then complete the full build after July 10.

Best regards

I have emailed the FTP info to you now.

This would be tough in terms of time available for it, but I will try to do my best.
