i'm new php , i'm using slim framework develop simple rest api. according docs, slim uses fastroute . i have route optional params (vendor , quantity) that: path/items/{id}/{name}/{price}[/{vendor}[/{quantity}]] the problem if leave vendor blank value of quantity goes vendor , quantity not filled. understand fast routes can't achieve that. but, how can it? can fast routes? can slim? is there framework can achieve want? should use query strings? (i think answer, need more knowledge). thank you. if going have optional parameters, of same types , can sent in order, either use query strings, or have fixed format add 0 instead of omitting it. example "vendor" isn't set: /10/somename/15/0/12 then parameters aren't optional in url/route can handle in controller instead, ignoring them if param zero.

my professor gave our first assignment (cs315), involves dealing huge (odd) integers , determining if prime. started in c++ until realized long long ints not hold numbers needed, left choices of making class of vectors in c++, or learning python in few days. simple piece of python code supposed spit out odd 256 bit random number. spits out random numbers, both , odd, , don't know why, guess is simple syntactical error not seeing. import random x = random.getrandbits(256) if x % 2 == 0: x + 1 print x you need assign x + 1 x . can either this: x = x+1 or this: x += 1

since app big try simplify below: tagcomponent : @component({ selector: "tag", template: `<div *ngfor="let of arr">{{a}}</div>` }) export class tagcomponent{ @input() arr: string[]; add(){ this.arr.push("abc"); } } appcomponent : @component({ template: `<p><tag [arr]="data"></tag></p>` }) export class appcomponent{ data: string[]; //some other code } so, when add() called, first time app scrolls top automatically , occurs in outlook desktop running modified version of ie 11. bit difficult understand problem , give solution hints might cause count answer.

i´m trying install package opencl in r on windows. installed opencl , have header files (i.e. cl\opencl.h). it's in c:\program files (x86)\intel\opencl sdk\6.1\include . however, when try install opencl via: install.packages("opencl", type = "source", # tried many variations on without luck install_opts = "c:/program files (x86)/intel/opencl sdk/6.1/include") then following error: ocl.c:6:23: fatal error: cl/opencl.h: no such file or directory #include <cl/opencl.h> ^ to me means r not know cl/... folder is. how can tell install.packages is? similarly, how install package via command prompt? in advance!

i wrote sql query , used textfield getting data. when textfield empty, gives data. how can stop that? here code: string sql = "select * boek naam '%" + txtnaam.gettext() + "%' or auteur '%" + txtauteur.gettext() + "%' or categorie '%" + txtcategorie.gettext() + "%' or opleiding '%" + txtopleiding.gettext() + "%' not opleiding '%" + txtopleiding.gettext() + "%' "; i guess looking query text field(s) has value , ignore rest empty. my suggestion be: 1) write java logics determine inputs program first. e.g. author, category selected fields , not empty. 2) run dedicated sql queries facilitate search inputs selected. e.g. in case, select using author , category so, there few sql queries there. not 1 handles everything. less confusing in opinion. hope helps :)

edit: question not answered linked reply. i'm still stuck on this... i've got table use chat messages. each message variably-sized box including text. want row height in table dynamically change depending on size of message box. if tick 'automatic' size style in ib, makes of rows have tiny heights. looks ios have uitableviewautomaticdimension automatically scales table, can't find nstableview. i know there's option create following function: func tableview(_ tableview: nstableview, heightofrow row: int) -> cgfloat { return 50 // ???? } and able set row height using (the above sets of rows height 50), don't know how make dependent on size of text in box. how can efficiently? here's 1 solution first set nstextfield in code. "virtual" field in never drawn var fakefield = nstextfield() // set fontsize etc use in table then in heightofrow function func tableview(tableview: nstableview, heightofrow row:

i have pasted text in cell a1 may this: "vanguard - total market - composite" or "vanguard - total market - commingled" i want cut off " - composite" or " - commingled" , return rest in cell b1. i'm using formula in b1: =left(a1,find(" - composite",a1)-1) however, can't figure out how multiple terms (i.e. composite or commingled). there formula accomplish this? if not, how in vba? thanks help! if understand correctly, you're looking strip past second occurrence of - , i.e. returning trimmed (extra whitespace removed) text left of first - character. adapting this solution locate last word in string, it: =trim(substitute(left(a1,len(a1)-len(mid(a1,find(char(1),substitute(a1,"-",char(1),len(a1)-len(substitute(a1,"-",""))))+1,len(a1)))),"-","",2)) this formula work or without spaces around - , , regardless of follows: if spacing important, can w
