i need assign dynamic attributes (like entity types) custom content type created. entity types have name , 2 additional attributes. i've not seen way assign additional attributes taxonomy term, think shoud use cck field , make reference in main cck, true? thought typical use-case taxonomy if cannot add attributes not useful me. you use node auto term module (or 1 of several alternatives, nat looks developed), (effectively) turns taxonomy terms nodes, , vocabs content types. means can add fields content type using cck, , add attributes terms. note module (and others perform same function) enforces relationships between vocab , content type, , terms vocab , nodes of type. you can achieve same thing without module if don't need automation or enforcement - create 1 node per term, tagged term, , pull node views access fields.

i have noticed uitableview comes couple of bind() methods. looks that's alternative implementing uitableviewsource on , on again, or wrong? have samples? other samples of binding interesting, binding textfield model using monotouch. rené the method you're looking @ is: http://developer.apple.com/library/mac/#documentation/cocoa/reference/applicationkit/protocols/nskeyvaluebindingcreation_protocol/reference/reference.html this has nothing uitableview or uitableviewsource data binding.

i'm supposed implement web application user log's in , registers sort of events (in case, alarms). when alarm happens, server needs push alarm of clients. at moment i'm using gwt on client side jetty on server side is implementing server push using jetty continuations idea? requirements are: the number of clients quite small (<20) increase in future alarms must not lost (i.e. if client down, must not miss alarms) if client goes down, other clients need informed (or @ least admin should receive sort of notification, e.g. mail). the main reason using comet (e.g. jetty continuations) is, allows reduce polling frequency. in other words: can achieve same thing without comet, using frequent polling client side. alternative choose depends on characteristics of application - depending on that, each alternative can more or less efficent other! in case, since need notifications when client goes down, makes sense use frequent polling. comet (long polli...

trying catch keyinput in silverlight application gives me problems because of focus of controls. page consists of multiple controls every time diffent control has focus , keydownevent fails. 1 possibility assing keydown event controls , method processes them. there better way? you catch keydown in page contains controls overriding onkeydown. protected override void onkeydown(keyeventargs e) { // distribute listeners here } this works since controls on page bubbles event upwards if control (like textbox/button etc) doesn't handle keypress parent control gets chance.

is there kind of encryption , decryption functions in c# , oracle pl/sql? mean can encrypt string in 1 , decrypt in other? help, i'm not in security algorithm! cheers in oracle, can use dbms_obfuscation_toolkit. if want encrypt , decrypt, might try des encryption. oracle, dbms_obfuscation_toolkit.desencrypt , , c# descryptoserviceprovider (in system.security.cryptography). you'll need use same key of course if encrypting/decrypting between two. also, dbms_crypto intended replace dbms_obfuscation_toolkit believe, , should have various encryption algorithms oracle.

i want compare 2 strings , 1 of them may null string, using stringcomparison.invariantcultureignorecase feature of c#. throws exception in runtime when null string encountered. shall able compare null strings? as options given you, can consider using stringcomparer.invariantcultureignorecase instead. stringcomparer handles nulls without throwing exceptions: using system; class test { static void main() { stringcomparer comparer = stringcomparer.invariantcultureignorecase; console.writeline(comparer.compare("a", "a")); console.writeline(comparer.compare("a", null)); console.writeline(comparer.compare(null, "a")); } }

so have 2 column layout, structured this: html structure: #container #content #side-a .janitor css: #container{ width: 501px; } #content { float: left; width: 300px; border-right: 1px solid black; } #side-a{ float: right; width: 200px; } .janitor {clear: both; } when there no border fine, when add it, layout collapses on zooming out. that's because border width added content width specified. #content 300px, #side-a 200px - that's 500px altogether. #container 501px. without border's, you've 1px still left, but... adding border, 1px, makes #content 300px + 2px wide, #side-a 200px + 2px wide. i'm surprised doesn't collapse when zoomed in. you can fix using: box-sizing: border-box; (with appropriate vendor prefixes).

possible duplicate: is there effective tool convert c# java? i'm not experienced java , have lot of c# translate java syntax become compilable. reason: android , google cloud i know api/platforms have different structures, lets dont need 100% compability, "core functionalitet" translated. gui 1 story of own, i've learned. instead of rewriting every switch-case, rebuild every class etc. nice "map" objects java equals , recompile on android/google platform. i sure there cant translated "c# thing" - every language possible generate .net/mono thought there might java -> .net available , therefore decompiler kinda thing? so there easy ways overcome translation frameworks, sdk or other similar methods take 80-95% of task automatically? have here: jsc . but beside, there c# concepts don't easyli translate java.

in our delphi application, use tstringlist store strings , corresponding objects. project, need similar in c#, not sure effective way of doing is. far i've thought of using array list, list, or dictionary. 1 of these effective @ want do? if not, way go? it depends features of tstringlist need. there's not direct replacement. a dictionary<string,object> unordered, , cannot have duplicate strings. there's no text property set strings @ once, etc. if ok you, i'd go that. otherwise, might consider defining little class like: public class item { public string string {get;set;} public object object {get;set;} } and use list<item> . gives ordered list of (string,object) tuples.

if have 2 classes a , b , such b inehrits a . in other words, a base class, , b derived class. now, suppose class a has private members. since class b inherited class a , private data members became part of class b . as know, private members said not accessed derived classes, but, in derived class. value of privacy in case? thanks. they aren't usable in way member functions of b , useful member functions of a , b in turn rely on. it's level of encapsulation ( b shouldn't care how functionality of a implemented).

vb.net 2010, .net 4 hello all, my question is, imagine have 2 list(of t) objects , subroutine in multithreaded environment modifies both of these objects. don't understand locks well, i'm unsure whether can do: synclock ctype(list1, ilist).syncroot list1.clear() list2.clear() end synclock or must i: synclock ctype(list1, ilist).syncroot synclock ctype(list2, ilist).syncroot list1.clear() list2.clear() end synclock end synclock ? insight? on right track? comments appreciated. thanks lot in advance, brian first, bad practice lock on non-private object, else might lock on it, , things go downhill there, instead lock on private member object, like class class1 private lockobject new object public sub clear() synclock lockobject ... end synclock end sub end class now, actual question: unless every operation modifies both lists (doubtful), should have 1 lock per list. while possible use 1 l...

let's have function f() takes list , returns mutation of list. if want apply function 5 member variables in class instance (i), can this: for x in [i.a, i.b, i.c, i.d, i.e]: x[:] = f(x) 1) there more elegant way? don't want f() modify passed list. 2) if variables hold simple integer (which won't work slice notation), there way? (f() take & return integer in case) another solution, though it's not elegant: for x in ['a', 'b', 'c', 'd', 'e']: setattr(i, x, f(getattr(i, x)))

here scenario researching solution @ work. have table in postgres stores events happening on network. way works is, rows inserted network events come , @ same time older records match specific timestamp deleted in order keep table size limited 10,000 records. basically, similar idea log rotation. network events come in burst of thousands @ time, hence rate of transaction high causes performance degradation, after sometime either server crashes or becomes slow, on top of that, customer asking keep table size million records going accelerate performance degradation (since have keep deleting record matching specific timestamp) , cause space management issue. using simple jdbc read/write on table. can tech community out there suggest better performing way handle inserts , deletes in table? i think use partitioned tables, perhaps 10 x total desired size, inserting newest, , dropping oldest partition. http://www.postgresql.org/docs/9.0/static/ddl-partitioning.html this mak...
