I get "double clutching" but not double dereferencing. :-) The other issue that came to mind is some code that allowed me to retrieve data from SAP using web services, converting the XML to JSON, and then using OB Get and OB get property names to assign the data to the dynamic variables on the form. All of the assignments are done using one For loop. Blindingly fast and very easy to maintain because everything is based on the object name/dynamic variable name. > > Lastly, working with c-obj just feels fast.

The takeaway for me was that they're both incredibly fast but C_Object is faster than an array and C_Object gets progressively quicker as the data set grows. C_Object is missing data manipulation routines that OT provides - find in array, update a particular element in an array, etc. I've created methods to perform those functions with C_Object and have come up with elapsed times that are the same that you're hitting. -- Douglas von Roeder 949-336-2902 ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
