You could use custom .NET control (table or listbox with embedded comboboxes, checkboxes,etc), but it's a bit tricky.

Thank you, good point. The main requirements are multi–level logging and ability to disable any module to be logged. I will try to implement observer, it’s going to be challenge to re invent well known pattern for LabView paradigm.

Hi guys, I am currently working on quite big project based on LVOOP, and I can’t decide on how to implement logging? At least I have hardware, protocol, and software logic layers. I was thinning to use singleton Log class, also Observer pattern can work. Can somebody advice how to organize logging approach? Any examples from your experience are appreciated. P.S. Sorry if my English is silly sometimes.
