Is it possible to update ad hoc data via Real-time events, by detecting a change of a parameter table inside by using the IGQIUpdater Interface?
or what would be a better way to go about doing so?
Hi Frans,
Yes, that’s definitely possible. DataMiner emits events whenever changes occur in the parameter table, and there are multiple ways to subscribe to those events. Once you detect a change, you can interpret it and propagate it through GQI as needed.
Also note that a “Parameter table by ID” data source already supports native real-time events, so if you’re targeting a specific table, there’s no need to create an ad hoc data source.
A simple solution might be to always wrap tags with the delimiter, even if they're at the beginning or end. This way, you can reliably use contains with the delimiter as both prefix and suffix. For subscribing, you can use low-level IConnection subscriptions, or a higher-level interface like IDMS.
Thank you Sebastiaan, do you have an example on how to subscribe these events?
unfortunately the parameter table by ID cannot filter out what I require.
I have a column that contains tags that are ; delimitted. (eg tag1;tag2;tag3) the adhoc does this filtering and only shows the instance where the tag is selected.
filtering the table and using contains might work but does not cover the edge case where "tag1" is selected and anything from tag10-tag19 showing up
