vba - Clearing cell contents prevent next button to be added -


i want replace cell values buttons, clearing value prevents next button added. here's script:

private sub workbook_open()     dim sh worksheet     dim btn button     dim cell range     each sh in activeworkbook.worksheets         each cell in sh.usedrange.cells             if cell.value = "{magic_value}"                 set btn = sh.buttons.add(cell.left, cell.top, cell.width, cell.height)                 btn                     .onaction = "buttonclickhandler"                     .caption = "btn_" & cell.left & "_" & cell.top                     .name = "btn_" & cell.left & "_" & cell.top                 end                 cell.clearcontents ' works without line             end if         next     next end sub

when open workbook, first button added next buttons not, , runtime error '1004' occurs: unable property add of class buttons (my translation). , debugger points line set btn = sh.buttons.add ...

from research, reason line cell.clearcontents. can't imagine how error related cell clearing.

i'm sorry, problem in code didn't show you:

private sub workbook_sheetchange(byval sh object, byval target range)     sh.unprotect pwd     target.locked = false     sh.protect pwd end sub

updating cell's value raised sheetchange event. solution temporarily disable events:

application.enableevents = false  each sh in activeworkbook.worksheets ...  application.enableevents = true

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
