Hi Sean
The story so far...

Do individual menu items really have individual handles?
Maybe Win.SendMessage(zButtonHandle,240,0,0)
only works for checkboxes in dialogs, not for checkable menu items?
I tested all your suggestions,
in various apps which have checked menu items.
For all child handles, and for all child indexes,
Win.SendMessage(zButtonHandle,240,0,0) always returns 0
and the Child text never equals any menu item's label.
here are my test scripts:
;;--------- Test All Child Handles ---------------
local i zButtonHandle zChildText
local zParentHandle = win.handle("winzip")
local zButtonList = Win.Childhandlelist(zParentHandle)
;; I also tried:
;; local zButtonList = Win.Childhandlelist(zParentHandle,"c=button")
local zListSize = word(zButtonList,0)
win.debug(zListSize," :: ",zButtonList)
for (i=1;i<=zListSize;i=i+1)
zButtonHandle = word(zButtonList,i)
zChecked = Win.SendMessage(zButtonHandle,240,0,0)
zChildText = win.childtextbyindex(zParentHandle,i)
win.debug(i," ",zChecked," ",zButtonHandle," ",zChildText)
endfor
quit
;;----------- Test All Indexes --------
local zParentHandle = win.handle("calculator")
local i zChecked zChildText zButtonHandle
for (i=1;i<300;i=i+1)
local zChildText = win.childtextbyindex(zParentHandle,i)
if(_EOF_ == 1)do
;; after all indexes are processed, _EOF_ == 1
break
endif
zButtonHandle = win.handlefromindex(zParentHandle, i)
zChecked = Win.SendMessage(zButtonHandle,240,0,0)
win.debug(i," ",zChecked," ",zButtonHandle," ",zChildText)
endfor
quit
;;------------------------------------------------
I also tried win.childtextbyid() instead of win.childtextbyindex()
in a similar script
;;-----------------------------------------------
I also tried things like this, with various apps,
using the labels of menu items which use checkmarks,
but they always returned blank lines (no handle):
win.debug(Win.Handle("winzip","Reuse WinZip Windows"))
win.debug(Win.Handle("winzip","&Reuse WinZip Windows"))
Maybe there is no way to test whether a menu item is checked.
