excel - How to tell macro to perform Match, Index formula using another cell with Match, Index data? -


i have excel workbook 2 master sheets , 1 data entry sheet.

project master:

|project no  |asset no    | |------------|------------| |p01         |a01         |

asset master:

|asset no   |description   | |-----------|--------------| |a01        |testing       |

for data entry sheet, want use project no reference , use index/match formula in vba search other 2 fields. in case:

|project no  |asset no   |description  | |------------|-----------|-------------| |p01         |a01        |testing      |

i want data entry sheet change selected row instead of refreshing entire sheet whenever change single cell. in vba data entry sheet used code:

private sub worksheet_change(byval target range)  if not intersect(target, range("a9:a9999")) nothing '---------------------------------------------------------------  target.offset(0, 1)     .formular1c1 = "=if(isna(index(projectentry,match(rc1,projectentry[project no],false),2)),"""",index(projectentry,match(rc1,projectentry[project no],false),2))"     .value = .value  end   target.offset(0, 2)     .formular1c1 = "=if(isna(index(assetmaster,match(rc1,assetmaster[asset no],false),2)),"""",index(assetmaster,match(rc1,assetmaster[asset no],false),2))"     .value = .value  end  end if  end sub

when used code, asset no appears while description remains empty. code should supposedly perform change in row whenever cell in range selected (a9:a9999) has value changed.

is due code limitation having refer 2 master sheets refers project master while asset master ignored? there way solve issue?

you have bug in second formula. should read:

 target.offset(0, 2)     .formular1c1 = "=if(isna(index(assetmaster,match(rc2,assetmaster[asset no],false),2)),"""",index(assetmaster,match(rc2,assetmaster[asset no],false),2))"     .value = .value  end

the rc1 have should rc2 (or rc[-1]).

edit:

a better formula use (thanks excelinefendisi) can seen in following code:

private sub worksheet_change(byval target range)    if intersect(target, range("a9:a9999")) nothing exit sub   '---------------------------------------------------------------    target.offset(0, 1)     .formular1c1 = "=iferror(index(projectentry[asset no],match(rc[-1],projectentry[project no],0)),"""")"     .value = .value   end   target.offset(0, 2)     .formular1c1 = "=iferror(index(assetmaster[description],match(rc[-1],assetmaster[asset no],0)),"""")"     .value = .value   end  end sub

but, lot of comments suggest, best way refresh edited row calculations in vba , write results sheet.

the following code using tables' listobject objects:

private sub worksheet_change(byval target range)    if intersect(target, range("a9:a9999")) nothing exit sub   '---------------------------------------------------------------    dim Ä excel.application: set Ä = excel.application   dim varvalue variant    varvalue = Ä.index(Ä.range("projectentry[asset no]"), Ä.match(target.value2, Ä.range("projectentry[project no]"), 0))   target.offset(0, 1).value = iif(iserror(varvalue), vbnullstring, varvalue)   varvalue = Ä.index(Ä.range("assetmaster[description]"), Ä.match(varvalue, Ä.range("assetmaster[asset no]"), 0))   target.offset(0, 2).value = iif(iserror(varvalue), vbnullstring, varvalue)  end sub

note usage of application. instead of worksheetfunction. access worksheet functions. this, coupled use of variant type variable, allows trap error occurs if match fails.

hi i'm using ngfor create set of 3 slides while starting in middle i'm guaranteed able slide left or right on start. when slide right can simple listen reachedend , push slide array i'm looping. but have problem adding slide beginning. if same above , use e.g. array.unshift() or spread add item beginning, view think it's on position 0 , snaps view new slide. the code below work animates slide change index 1. slide = [0,1,2] //example loop slidechanged(event) { if(this.slides.isbeginning()){ this.slide = [this.slide[0]-1, ...this.slide]; this.slides.update(); this.slides.slideto(1) } } <ion-slides [initialslide]="1" (ionslidedidchange)="slidechanged($event)"> <ion-slide *ngfor="let item of slide"> <h1>slide {{item}}</h1> </ion-slide> </ion-slides> any appreciated! you can using ionslidenextend , ionslideprevend events slides . please

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
