i have assembly, mainlib.dll, resource retrieve with: string resourcepath = string.format("mainlib.{0}", "embeddedresource.txt"); var assembly = assembly.getexecutingassembly(); stream inputstream = assembly.getmanifestresourcestream(resourcepath); this works fine. need move embeddedresource.txt it's own lib, resourcelib.dll. how retrieve resourcelib.dll , use in mainlib.dll in separate dll? you need resourcelib assembly embedded resource - var assembly = assembly.getassembly(typeof(classnameinthatassembly)); or var assembly = assembly.loadfrom("resourcelib");

php novice here. goal to: a) display table of booking options (fitness classes) dynamically database records, allow user select multiple options checkboxes against each row - bit's working. b) pass checkbox selection table listing selected data on confirmation page. i'm getting error here: invalid argument supplied foreach(). c) update database when user hits second page's 'confirm' button. research far uncovered this advice on using $_get , $_post achieve array. my checkbox code on initial page: echo '<form action="makebooking.php" method="get">'; echo '<td><input type="checkbox" name="class_id[]" value=' . $row['class_id'] .

i dont know if makes sense or not here is there way can 2 words regex result each time? supose have text file contains string such following : alex fenix engineer works ford automotive company. personal id <123456>;etc.... basically if use \w list of : alex fenix engineer , etc they separated white space , punctuation marks asking , whether there way have list such : alex fenix engineer works ford automotive company personal id 123456 how can achieve such format? possible or should store first results in array , iterate through them , create second list? way please note item alex fenix abstraction of map or container that. reason asking trying see if there way can directly read file , apply regex on , second list without further processing overhead (i mean reading map or string , iterating through them , creating pairs of tokens , carry on ever needed ) try regex \w \w it match word followed space , word. although can achieve such fo

i can same thing 2 types of code snippet. first way: string makedate = integer.tostring(now.year) + integer.tostring(now.month) + integer.tostring(now.monthday); or second way: string makedate = now.year + "" + now.month + "" + now.monthday; my question is: which method preferable [first way or second way]? which code snippet execute faster? the 2 snippits show identical. a string in java immutable ; can't changed. when using concatenation operator ( + ) compiler generates code using stringbuilder for example second snippit becomes: string makedate = new stringbuilder() .append(now.year) .append("") .append(now.month) .append("") .append(now.monthday) .tostring(); you can @ generated bytecode see this. java comes program javap allows @ compiled .class . i created simple main() provide minim

i working on wav files, tring parse them. don't wanna use libraries . open wav file fstream , read data vector. want parse wav file header . example want filesize between 4th , 8th bytes. want assign integer . accomplish memcpy .but since c++ don't wanna use memcpy. solution end : std::vector<unsigned char>::iterator vectorite = soundfiledatavec.begin(); vawparams.totalfilesize = 0; //since little endian used reverse_copy std::reverse_copy(vectorite + 4, vectorite + 7, (unsigned char*)&vawparams.totalfilesize); i not happy (unsigned char*) cast integer pointer .i suspect there better way do. can please advice me better way? vectors use contiguous storage locations elements, elements can accessed using offsets on regular pointers elements. if don't want memcpy trivial solution is: int header = *reinterpret_cast<const int*>(&soundfiledatavec[4]); this reads 4 bytes (that may need convert 1 endianness another).

i working on project involves sending emails using java. using javamailx module( had imported). i know maximum number of recipients whom can send our email ( mime message consisting of message, subject , attachments ) in 1 go. limit on number of recipients can emailed together. have searched online , on stackoverflow , there no clear answers. using gmail smtp server send emails gmail accounts , yahoo smtp server send mails yahoo accounts. do maximum number of recipients depend upon these smtp servers ? if default limits on them ? personal experience can tell academic email allows sending mails multiple people in 1 go ( whole mailing lists consisting of 200-300 people). not sure how works in end, if go in small groups of recipients or in total. no limits specified in api documentation, limits inherent in implementation (i.e. memory). also, sending and/or receiving smtp server limits reached before limits imposed implementation.

i need add class 1 element when dragged on element. in html5 http://jsfiddle.net/neaut var draggeddiv = document.queryselector('.draggeddiv'); draggeddiv.draggable = true; var draggedover = document.queryselector('.draggedover'); draggedover.ondragover = function(){this.classname = 'red'} but don't know how work in ie8.

precision , recall metrics evaluation algorithms, , defined this: precision = true_positive / (true_positive + false_positive) recall = true_positive / (true_positive + false_negative) so, think every algorithm have 1 number precision , 1 number recall, see there diagram evaluating according precision , recall, want know how can draw diagram 1 point?(one precision , 1 recall every algorithm) you draw histogram precision , recall each algorithm. it's still bit difficult read because each algorithm there 2 values. need decide important characteristics: recall or precision? have considered using f-measure tries combine both measures? http://en.wikipedia.org/wiki/f1_score edit: my suggestion use histogram: but solution plot this: both done using libreoffice.

this question has answer here: unresolved external symbol on static class members 3 answers i want keep track of instance of myclass , have add private static variable std::map<int,myclass*> inside myclass. problem causes unresolved external symbol, don't know how debug. how can resolve this? note: i'm seasoned java programmer , novice c++ programmer, , i'll using jni dll , why need keep track instances of myclass . you haven't provided implementation: myclass.h: class myclass { private: static std::map<int, myclass *> m_instances; ... }; myclass.cpp: #include "myclass.h" // add std::map<int, myclass *> myclass::m_instances;
