containers take hashable objects (such dict keys or set items). such, dictionary can have 1 key value 1 , 1.0 or true etc. (note: simplified - hash collisions permitted, these values considered equal) my question is: parsing order well-defined , resulting object predictable across implementations? example, osx python 2.7.11 , 3.5.1 interprets dict so: >>> { true: 'a', 1: 'b', 1.0: 'c', (1+0j): 'd' } {true: 'd'} in case, appears first key , last value preserved. similar, in case of set : >>> { true, 1, 1.0, (1+0j) } set([(1+0j)]) here appears last item preserved. but (as mentioned in comments): >>> set([true, 1, 1.0]) set([true]) now first in iterable preserved. the documentation notes order of items (for example in dict.items ) undefined, question refers result of constructing dict or set objects. the bug fixed in recent versions of python explained in @jsf's answer d...

i'm trying have hashmap keyed circuitid class . circuitid class contains string clci member , class overrides hashcode()/equals() using clci member's hashcode()/equals() . i wanted can lookup map using simple string , away converting string circuitid object lookup map. doesn't work , think because hashmap uses evaluation form (key==null ? k==null : key.equals(k)) key input key , k key entry in map, key.equals(k) part. i'm wondering why hashmap didn't k.equals(key) instead? (at least way, think i'm trying have worked.) being that's not case, there trick this? if have overridden equals() check handle if key being passed string or actual circuitid object, don't understand why wouldn't have worked. whether container compares circuit string, or string circuit implementation-specific, , not guaranteed same in future releases of jre. generally, given 2 objects a , b , expected a.equals(b) when b.equals(a) , vice-versa. cal...

there weird problem application code facing. have wpf application (desktop) in .net 4.0. uses third party control devexpress. this application being supported wcf windows service, in .net 4.0 through our logs, noticed in wpf application, main gui thread has taken culture such datetime.now in thread gives time of 1 hour behind i.e. if system time 1.20 pm, gui thread (through datetime.now) gives 12.20 pm. however, other threads in application e.g. timer threads or background worker thread giving correct time. in wcf windows service also, noticed main thread running services or timers within service fine. however, have created new thread (using thread t = new thread()) , thread taking wrong culture i.e. datetime.now in thread return 12.20 pm instead of 1.20 pm. it mysterious us. can please help?

i have stored procedure 2 updates, want first update if parameter @active equals 'y' . alter procedure sp_updatethis @something varchar(5), @active char(1) begin -- check see if active , update update mytable set this=@something -- run 1 regardless update yourtable set that=@something try changing last line this: if (@active = 'y') begin update yourtable set that=@something end

i have input text field in webpage. need validate field field contain both text , numbers. ie input box if cost need validate if cost in format of '100 r' i have validated number, how can validate text , number var number = document.forms["myform"]["cost"].value; if (isnan(number)) { alert("cost must in number"); document.myform.cost.focus() return false; }

i want match right string regular expressions, can't. import re str = "<meta apple <meta" \ "we go<meta" \ "goto mac <meta td yiyang ziyou" \ "net<meta aaask zoie go?" \ "<meta " \ "buy mac" r = re.findall("<meta(?!.*<meta).*mac", str, re.s) i think there matched 2 strings, 1 <meta goto mac , <meta buy mac , got last. why? use pycharm 5.0.3, version of python 3.5.1. thank you. the problem have negative look-ahead operator (?!.*<meta) means match, there must not <meta later in string. for reason, last <meta string matched, because can satisfy criteria.

i created 2 dimensional array of strings , populated it. try bind datagrid control so: string[][] array = new string[100][]; datagridview.datasource = array; instead of seeing contents of array see following columns: length, longlenth, rank, syncroot, isreadonly, isfixedsize, issyncrhonized. so instead of displaying contents of array, displays properties of array. did wrong? when allow grid control auto-generate columns, enumerate through properties of object , create column each one. has no way know want display grid of array values. you'll need create new object (such enumerable list of class) out of array properties want bind columns. quick way use anonymous type, built using linq query. like: string[][] array = new string[100][]; for(int = 0; < 100; i++) // set values test array[i] = new string[2] { "value 1", "value 2" }; datagridview.datasource = (from arr in array select new { col1 = arr[0], col2 = arr[1] }); page.databi...
