IC Tore already put you on the right trail ;-)

I was isolated mostly from that particular change by my desire to minimize calls across COM boundries in the spirit of "chunky, not chatty" from RPC method calling ;-))

if you look closely at the typical lines from Ricks script

oButton = o.document.getElementById('btnSubmit')
? oButton
oButton.Click(.F.)

marshalling is done 4 times, as COM oButton is returned to vfp an a method is called there. I have a standard JS object, which has methods to call which in turn get the Element and call the method in pure JS runtime, eliminating half the marshalling at the cost of some duplicated code on JS side to minimize JS method calls and in a few times additional string comparison. Pattern for signature:

oHelper.click("ButtonName")
oHelper.setstr("ControlName", "NewValue")

and so on. More than 2 decades ago this was markedly faster, probably today still is, even if CPU speeds,RAM access caching and so on changed quite a bit.

A pattern to consider ;-))

>>Yes, nearly identical, as IE is activeX. Did a lot of that last century when IE was dominant, but today more and more devs want to escape IE problems. Also I found newer versions of IE to be less stable as activeX components than in IE4-IE6 times, but that might be a misperception as back then I spent much more time roboting WebBrowser and InternetExplorer.Application.
