let's i'm working on static library foo.a , makes use of function in bar.so . how build library in such way uses foo.a in project doesn't have explicitly link against bar.so ? what can in libfoo.a make call dlopen dynamically link libbar.so . then, use dlsym locate function want use. typedef void (*barfunctiontype) (const char *); functiontype barfunction; void initialize_foo_lib () { void *h = dlopen("libbar.so", rtld_lazy); barfunctiontype barfunction = (barfunctiontype) dlsym(h, "barfunction"); // note scary looking cast function pointer. //... rest of code can call barfunction } libbar.so should c library, or function should extern "c" if c++ library, find function name properly. otherwise need mangle name find function dlsym . can use objdump -t on library check if names in library mangled. realize there still dependency on libbar.so , baked static library. user of libfoo.a not have add -lbar link line when link in -lfoo ...

in intent.action_view intent? class or method , here action_view ? variable , type of it's ? please explain in details. thank you. intent in android abstract public class . action_view action on intent. public static final string action_view since: api level 1 activity action: display data user. common action performed on data -- generic action can use on piece of data reasonable thing occur. example, when used on contacts entry view entry; when used on mailto: uri bring compose window filled information supplied uri; when used tel: uri invoke dialer. input: getdata() uri retrieve data. output: nothing. constant value: "android.intent.action.view" you need read developers guide android. better understanding here .

all, i have ajax function, calls php url through html data type. cannot use other datatypes ajax requests due server constraints. trying print message , handle scenarios based on return code. following code doesn't seem work. can advise? here's simple ajax call: $.ajax({ type: "post", url: "validateuser.php", datatype: html, success: function(msg, errorcode){ if(errorcode == 10) { callafunction(); } else if(errorcode == 20) { callsomething(); } else { dosomethingelse(); } } }); php code: --------- <?php function validateuser() { $username = 'xyz'; if (!empty($username) && strlen($username)>5) { echo 'user validated'; return 10; } else if (empty($username)) { echo 'improper username'; return 20; } else if (strlen($username)<5) { echo 'username length should atleast 5 characters'; return 30; } exit; } ?> thanks your php function. not being called. also, not sending data php file.

i'm trying make program @ each previous number in list, , determine if number bigger it. if is, should record how many times bigger, , return @ end. i.e. count (i'm using num variable) starts @ 0. 10 bigger 7 num becomes 1. 7 isn't bigger 20 count stays same. 20 bigger 15 count (num) 2. , 15 bigger 4 (count 3). 4 not bigger 6 (count not change) , 6 not bigger next number because there no next number. have now. i'm thinking lst[i] , lst[i+1] need used reference index maybe? can walk me through this? thanks. def count(lst): num = 0 sort of division here? add num variable? #main prog ( count([10, 7, 20, 15, 4, 6]) ) import numpy np def count(lst): return sum(np.diff(lst)>0) diff gives difference between successive elements, sum returns number of positive differences.

i looking @ http://wso2.org/forum/thread/10508 explains how httpservletrequest. explains if have "org.wso2.carbon.core.transports.http.*" request can httpservletrequest object. described did change axis2.xml change transports , worked. since "org.apache.synapse.transport.nhttp." (nio) trnasport fast loosing performance if that. is there way of keeping nio transport handlers ("org.apache.synapse.transport.nhttp.") , httpservletrequest object? i thankful if can answer. authentication done through cookies in existing data services , company not want change that. thanks abhijit this not possible. nio transport not servlet , not support http sessions , all. new wso2 server version have upgraded tomcat version normal http transport uses nio underline. i think need performance comparison , see latest release.

i using jad (no longer update?) decompiling .class file, on aix or linux, jdk 5 class not supported jad, (replied @thilo , in thread ). i know decompiling tools based on jad, there such tool both provides commandline interface(i know dj has gui don't want it) can call java , supports jdk5 .class? thanks. yes, there one, french project hosted on free.fr. luckily you, archive.org´s wayback machine has indexed,including download binaries. it decompiles java 1.5 , 1.6 too. here link http://web.archive.org/web/20110416091052/http://java.decompiler.free.fr/

i using java 7 watchservice watch directories. change directories watching. run exception: java.io.ioexception: network bios command limit has been reached. after 50 directories. call close() on each watchservice create before creating new one. does know proper way release watchservice not run limit? thanks, dave i think all need close() service. know said think already, suspect missing some. instance, failing close service instances in case of exception. should treat watchservice instance other io resources , close in block; e.g. watchservice ws = ... try { // use ... } { ws.close(); } or using java 7 "try resource" syntax. try (watchservice ws = ...) { // use ... } when watchservice closed, should free o/s level resources holds. the other possibility have run java bug in watchservice implementation.

what best strategy simpleaudioengine effects preload ? preload sound effects @ game startup ? or in each screen's creation preload effects used in screen ? loaded effects released @ point ? you preload if playing sound effect first time causes noticeable lag. action games want preload gameplay effects. turn-based or otherwise "slower paced" games may ok not preload sound effects. when , preload depends on needs. typically @ start of gameplay scene (ie during init or onenter). a preloaded effect not released unless call unloadeffect on it. internally audio engine caches sound effects, not exclusive preloading. playing sound effect load , keep in memory well.
