Excel runs very slow (with VBA) -


i have userform several drop-down lists, populated via vba macro. happens right @ beginning, on opening workbook.

once load done, workbook becomes slow. scrolling 1 cell causes noticeable lag, despite not having running macro.

on opening workbook, load() function called preps userform.

the userform has ~25 dropdown lists, populated separate sheet ("menu") stores values each of these dropdowns in separate column. "menu" sheet filled via load() function calls 1 of 2 menuquery() routines.

one of these pick distinct values columns in dbf file, other lists down options based on list in question.

snippets load() subroutine :

sub load()  application.screenupdating = true   dim mysht, datasht worksheet    set mysht = sheets("dashboard") set datasht = sheets("menu")   mysht.visible = xlsheetvisible mysht.activate  datasht.visible = xlsheetvisible datasht.activate   activesheet.range("a1:iv2000").select selection.clearcontents   range("a1").select call menuquery("a", "type", "hh", "cmbbox1") call menuquery1("b", "flow", "flow", "cmbbox2")    . '25 similar calls .  datasht.visible = xlsheetveryhidden      . .'hide sheets . sheets("triggers").visible = xlveryhidden sheets("actions").visible = xlveryhidden   mysht.visible = xlsheetvisible mysht.activate   end sub

what i've tried:

  1. have tried commenting out menuquery() functions , problem persists. guess isnt problem here
  2. tried application.screenupdating=false in beginning of function, no change
  3. in fact, tried not calling load() function, doesn't seem either!

if have excel vba macro code runs slow, chances it's caused excel having recalculate @ each line of code. deleting rows 1 of many things can become painfully slow. can overcome switching excel manual calculation before code runs. aware if code bugs out, , have no error trap, workbook left in manual calculation , no designed spreadsheet should ever used calculation in manual. if ever advice switch excel manual calculation prevent slow saving, closing , data entry...run fast! band aid approach rather addressing underlying cause. if run excel workbook in manual calculation it's matter of time before non-calculated data read off!
