excel - Using a class object to make different shapes -


my excel sheet creates map various layers, showing network made of lines, squares, dots, , triangles. have functions each creation take arguments such as

celllocation range  '(takes given cell location) shapetype string    '(oval, triangle, rectangle) color                  '(red, black, whatever) sizefactor double   '(factors shape size function of cell's width)

i learning classes now, wondering if classes useful in case, , how use them simplify code, rather having functions 6 different arguments , such.

originally had functions this:

function createwell(cellrng range, wellname string) 'creates square of particular color, size, etc in cellrng , names wellname  function createcompressor(cellrng range, compname string) 'creates oval of particular color, size , etc. similar other func.

then, because had 5 of these variations color, size, shape, etc. tried making overall function:

 function createshape(cellrng range, shpname string, _             shpcolor string, shpsize double, shptype string)

but seems messy (too many arguments). how can employing classes clean type of code?

you right. need use object oriented concepts of language. vba not complete object oriented language has nice features. cant write example because there more 1 way this. i wanted comment , not write answer low rating preventing me. read object oriented concepts , working classes, crating instances classes overloading function different stamps , enums. if want more modern language (like visual basic.net example) read inheritance , polimorphizem - important concepts implement tasks mentioned.

authentication - Mongodb revoke acccess to connect test database -

i have ec2 instance mongodb 3.2.0 installed. have user admin access. can connect user , perform operation remotely. 1 can connect database test remote if knows ip mongo 11.11.11.11. although not able make operations, want restrict access user credentials can connect server. first need create users , grant roles users, example: use admin db.createuser( { user: "myuseradmin", pwd: "abc123", roles: [ { role: "useradminanydatabase", db: "admin" } ] } ) then need start server --auth parameter mongod --auth more information here

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
