excel - Clear Constants in a range without clearing references and formulas -


i trying clear number constants in range of cells without clearing formulas or cell references. clearing constants cells without formulas or cell references simple having trouble doing when present. below code have far.

range("b2:b11").select selection.specialcells(xlcelltypeconstants, 1).select selection.clearcontents

in range cells b5 , b7 have formulas cell references follows:

b5: =(g83*h1)+1181.05

b7: =e33+1292.76

the cell references @ times reference cells on other sheets in same workbook. need clear constants these formulas while leaving references intact.

this remove constants formulas in current workbook based on 2 patterns:

  • "=formula-[space]-plussign-[space]-constant" (space optional)

    • =(g83*h1)+1181.05 or =(g83*h1) +1181.05 or =(g83*h1)+ 1181.05 becomes =(g83*h1)
    • =e33+1292.76 or =e33 +1292.76 or =e33+ 1292.76 or =e33 + 1292.76 becomes =e33

  • "=formula-[space]-minussign-[space]-constant" (space optional)

public sub clearconstantsfromworkbookformulas()     const patterns string = "~+*|~+ *|~ +*| ~+ *|~-*|~- *|~ -*|~ - *"     dim pat variant      each pat in split(patterns, "|")         cells.replace what:=pat, _                       replacement:=vbnullstring, _                       lookat:=xlpart, _                       searchorder:=xlbyrows, _                       matchcase:=false     next  end sub

.

this more generic option using regex pattern matching , arrays:

public sub testclear()     dim ws worksheet      each ws in application.activeworkbook.worksheets         removeconstantsfromformulas ws.range("b2:b11"), getregex     next end sub  public sub removeconstantsfromformulas(byref rng range, byref regex object)     dim v variant, r long, c long, lr long, lc long      lr = rng.rows.count     lc = rng.columns.count      if lr > 0 , lc > 0          v = rng.formula         r = 1 lr            c = 1 lc               if left(v(r, c), 1) = "="                  if regex.test(v(r, c)) v(r, c) = regex.replace(v(r, c), vbnullstring)               end if            next         next         rng.formula = v      end if end sub  private function getregex() object     set getregex = createobject("vbscript.regexp")     getregex.pattern = "[^a-za-z][0-9]+(\.?[0-9]+)"     getregex.global = true     getregex.ignorecase = true end function

regex pattern: 1 or more digits, digit group not preceded letter, or without fraction part

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

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...
