i have c++ application needs communicate c# application (a windows service) running on same machine. want c++ application able write many messages wants, without knowing or caring when/if c# app reading them, or if it's running. c# app able should wake every , , request latest messages, if c++ app has been shut down. what simplest way achieve this? think kind of thing msmq for, haven't found way in c++. i'm using named pipes right now, that's not working out way i'm doing requires connection between 2 apps, , c++ call writeline blocks until read takes place. currently best solution can think of writing messages file timestamp on each message c# application checks periodically against last update timestamp. seems little crude, though. what simplest way achieve sort of messaging? well, simplest way is using file store messages. suggest using embedded database sqlite, though: advantage better performance , nice way query changes (i.e. select * messa...

i have dll written in visual c++ , application written in c#. application written in c# uses ipc between multiple instances of ever runs 1 instance (it attempts start ipc server, , if can't assumes there's 1 running, in case sends command line arguments on ipc existing application). now want send commands visual c++, however, when create type definition in visual c++ matches 1 in c# (on implementation level), rejects connection because fundamentally still 2 different types (from 2 different assemblies). i thought using reflection in visual c++ fetch type c# assembly, can't because i'd have ship assembly along side dll (which defeats purpose of dll being api application). i'm not sure of other way it, other store class in yet dll , make both application , api dll reference class in that, not ideal solution i'd single api dll distribute. are there suggestions how can connect on ipc (other forms of communication tcp not permitted) send requests applica...

i have script: var a="thu oct 07 16:50:0 cest 2010"; var b=a.split("cest"); var d = new date(b[0]); alert(d);​​​​​​​​​​​ but doesn't work how want. in fact date result differs original in string. the input thu oct 07 16:50:0 cest 2010 result different sat oct 07 2000 16:50:00 gmt+0200 (cest). wrong? you're losing information year. split splits string array @ 'cest' of parse first element (the part of string left of 'cest'). either need add right part of string again or use better suited method replace : var a="thu oct 07 16:50:0 cest 2010"; var b=a.split("cest"); var d = new date(b[0]+b[1]); alert(d);​​​​​​​​​​​ var a="thu oct 07 16:50:0 cest 2010"; var b= a.replace('cest',''); var d = new date(b); alert(d);​​​​​​​​​​​

i'm building silverlight app want hosted in azure , use azure table storage. i have class represents main data entity, expenseinfo . has many data annotations ria validation, such [required] . i following tutorial set rest service access sl. wants there class in web role data serialization. class contain same data expenseinfo . so, want expenseinfo be? want separate classes in each project? put in 1 project, , instantiate in both? weird have class data annotations in server side web role? thanks, i'm new sl , azure. the pattern you're looking here data transfer object (dto) pattern . here's good article on pros , cons of pattern. personally, don't mind additional classes dto and/or , adapter pattern brings (you see adapter type patterns used on place, mvvm hot 1 right now). have strong dislike sharing business logic in assemblies across trust boundary, use dto/adapter in architectures.

i've been working way through tutorial . got stuck when asked me make class inherits tablestoragedataservicecontext . can't seem find .dll or namespace or whatever. dataservicecontext works fine. tutorial bit old. has class been moved or no longer exists or something? the tutorial you're following when azure in ctp, of class names changed when came out of ctp (they've been stable since then). class think meant refer tableservicecontext . it in microsoft.windowsazure.storageclient.dll installed in c:\program files\windows azure sdk\v1.2\ref if didn't change of settings while installing sdk . it might worth finding more date tutorial though, i'm not sure other minor differences there might be.

i'm working on oracle , perl. have 3 fields in table (a, b, c), , form, every row in table, string a_b_c using "join". c refers date. can take null values. in case , "join" return warning "use of uninitialized values in join". know have select nvl(c,something) a_b_something when c null. can suggest me "something" can be, if want distinguish between these rows , other rows. in short, can store other valid date or null value in date field? i know have select nvl(c,something) a_b_something when c null selecting isn't storing value in column, , oracle passes datetimes clients strings, it's entirely possible can use nvl(col, '') without confusing dbi @ all. if doesn't work out, can build whole thing in sql: select a || '_' || b || '_' || (case when c null '' else to_char(c) end) as 1 of columns.

i'd perform fulltext search against column, looking partial word match (ie: against('fra*' in boolean mode) ). receive results assign higher relevancy shorter words match. so, example, if perform search 'fra' , results 'frank', 'fran' , 'frankfurter', them ordered in terms of relevancy this: 'fran', 'frank', 'frankfurter'. is there someway can achieved? select token tokentable token '%fra' order char_length(token) asc to fullfill example, fast due btree indexing. can do: select document documents document '%frankfurter%' , document '%würstel%' order char_length(document) asc but nonsense of relevancy calculation. simple answer: if autosuggestion based on prefix, method above fine. theres no need use match against. if want search fulltext search cant such criteria, should @ lucene/ solr

from australian voting problem: a bot keep putting information , can reach 1000 lines. example of he'll enter: "1 2 3 2 1 3 2 3 1 1 2 3 3 1 2 " how know when has finished entering information? there \n @ end , that's guess on go. cin doesn't seem detect \n, getchar() apparently does. \n after first line of course, , getting work has become rather difficult. how accomplish this? std::string line; while( std::getline(std::cin,line) && !line.empty() ) { std::istringstream iss(line); int i1, i2, i3; iss >> i1 >> i2 >> i3 if( !is ) throw "dammit!" process_numbers(i1,i2,i3); } if( !std::cin.good() && !std::cin.eof() ) throw "dammit!";

i have used appdomain.currentdomain.getassemblies() list assemblies, how list built-in attributes in .net 2.0 using c#? note appdomain.getassemblies() list loaded assemblies... it's easy: var attributes = assembly in assemblies type in assembly.gettypes() typeof(attribute).isassignablefrom(type) select type; .net 2.0 (non-linq) version: list<type> attributes = new list<type>(); foreach (assembly assembly in appdomain.currentdomain.getassemblies()) { foreach (type type in assembly.gettypes()) { if (typeof(attribute).isassignablefrom(type)) { attributes.add(type); } } }

java noob here, i have iterator<typea> want convert iterator<typeb> . typea , typeb cannot directly cast each other can write rule how cast them. how can accomplish this? should extend , override iterator<typea> 's next, hasnext , remove methods? thanks. you don't need write yourself. guava (formerly google-collections) has covered in iterators.transform(...) you provide iterator , function converts typea typeb , you're done. iterator<typea> itera = ....; iterator<typeb> iterb = iterators.transform(itera, new function<typea, typeb>() { @override public typeb apply(typea input) { typeb output = ...;// rules create typeb typea return output; } });

in winforms application have myform.cs starts quite large. solve have created new file(myform.leftpanel.cs) using partial class of myform class subset of gui functionality. however once in while, not always, when go designer event handlers have moved myform.leftpanel.cs gets regenerated in myform.cs empty functions. causes compiler error until manually remove them in myform.cs. how can prevent these functions being regenerated? i saw question placing these kind of files under main.cs in project , solution tell visual-studio find existing functions? using method in winform partial classes placed myform.leftpanel.cs below myform.cs. so far seem have solved problem.
