Logic where there is Block Before or Block After with Select operations having corresponding controls on Form

In this case Select operations within Block Before/After are only parkable on Zoom action. This kind of logic is not in accordance to clean and clear development.

The conversion to event-driven mechanism is too complex, so it is not converted and a 'Too complex to convert' message is logged into conversion log.

You should change the logic before trying to convert it. Perhaps a logic where parking on controls within the Block Before/After is according to proper conditioning of the Allow Parking control property.
