Hello,
that's fairly weird, and not only because there seems to be no reason for the error.

I have tested now with the current build from the Web site (5.50.405.1), and it worked for me.
This build is on our Web since 9/29/2017. The previous build (5.50.334.1) has been there since 8/10/2017. The only difference is a totally unrelated minor fix that has to do with special licensing code for our partner.

Which version of Delphi are you using, and have you re-built the Delphi units from the type libraries? If you have not done that, please do so.

Regards

MonitoringParameters.SamplingInterval was created by Dq-soft
Hello, i have the following code used with demo version of Quickopc UA which i have downloaded yesterday:


1. MonitoringParameters := CoUAMonitoringParameters.Create;
2. i:= MonitoringParameters.SamplingInterval;
3. MonitoringParameters.SamplingInterval := 100;

Line 1 and 2 are working correctly, line 2 sets i to 0

Line 3 brings the following error : "Der Objectverweis wurde nicht auf eine Objectinstanz festgelegt" or in english i Thing it is : "Object reference not set to an instance of an object"


In the old demo Version that i had downloaded a view weeks before everything worked fine.

Can anyone help here ?

Kind regards
Dina
