after selecting cell having formula, select part of formula in excel formula bar , calculate (by pressing f9). need reproduce evaluation of sub-formulas javascript api. for example, let's assume values of cell a1 , b1 , c1 respectively 1 , 2 , 3 , , cell d1 contains formula =a1+b1+c1 . able evaluate sub-formula such a1+b1 , b1+c1 , , result 3 , 5 . in vba, under manual calculation mode, store initial formula of d1 in variable, , assign sub-formula (eg, =a1+b1 ) d1 result 3 , , restore initial formula d1 nothing happened; evaluation not raise calculation of other cells descendants of d1 (thanks manual mode). however, javascript api, re-calculation works under automatic mode. if assign sub-formula (eg, =a1+b1 ) d1 , cells descendants of d1 re-calculated ctx.sync , may costly. so there way or workaround optimise that? one possible workaround find isolated cell in workbook no cell depends on (eg, cell outside usedrange of worksheet, still need make sure no cel...

in following screenshot can see disassembly of cstring function getlength() lead crash. taken dumpfile, post mortem. crash caused sudden change of register eax 0. how can 6a6a4547 6a6a4549 register eax changed. in 6a6a4547 should have been set 0x6a8e7054 (0x38324964 {0x6a8e7054}). can see in watch window. in 6a6a4549 eax "0". why , how? can find out cause? side information: call stack looks normal no problems in variables or threads its compiled vs2012 compiler target platform x86 its on virtual machine program runs many threads getlength called millions of times per hour it of wrote - a race condition . in more upper part of software object not locked sufficiently. therefore eax became 0 in first assembly line. after thread "corrected" memory , looks eax register has been changed. so of crashes homemade. thanks of you!
