this question has answer here: why use in c#? 13 answers i'm teaching myself c# , studying try, catch , finally. book i'm using discussing how block runs regardless of whether or not try block successful. but, wouldn't code written outside of catch block run anyway if wasn't in finally? if so, what's point of finally? example program book providing: class myappclass { public static void main() { int[] myarray = new int[5]; try { (int ctr = 0; ctr <10; ctr++) { myarray[ctr] = ctr; } } catch { console.writeline("exception caught"); } { console.writeline("done exception handling"); } console.writeline("end of program"); console.readline()

i'm handling multiple events through event subscriber instead making separated events/listeners. enqueue several of these events didn't find way accomplish that. i've followed official documentation ( https://laravel.com/docs/5.2/events#event-subscribers ), there no clue of how choose events want enqueue(neither subscriber). any suggestions? (no individual event/listener, please) thanks in advance! if interested in, i've found solution looking deeper in event dispatcher. implementing contract shouldqueue on eventsubscriber works same separated event/listener , enqueue events on database. should documented in official site. regards.

i have camera , want camera follow player. player can walk around cube camera must keep radius player. i'm doing player's z x rotation of camera (with equation), problem is, x rotation of camera goes 0 90, @ 90 goes again 0 changes y , z rotation 180. gives me problems because should keep increasing x rotation 180 goes 90 0 again because y axis rotated automatically. how can dissable automatication? camerascene.transform.rotation = quaternion.euler(( 180 * (transform.position.z - boxmin.z) / width), 0, 0); newpos = new vector3(0, mathf.sin(camerascene.transform.eulerangles.x * mathf.deg2rad) * 35 + 25, mathf.sin((camerascene.transform.eulerangles.x-90)* mathf.deg2rad) * 35); camerascene.transform.position = newpos;

we have weblogic server running several apps. of apps use activemq instance configured use weblogic xa transaction manager. now after 3 minutes after startup, jvm triggers outofmemoryerror. heap dump shows 85% of memory occupied linkedlist contains org.apache.activemq.command.xatransactionid instances. list root object , not sure needs it. what cause this? we had same issue on weblogic 12c , activemq-ra. xatransactionid object instances created continuously causing server overload. after more 2 weeks of debugging, found problem caused weblogic transaction manager trying recover pending activemq transactions calling method recover() returns ids of transaction seems not completed , have recovered. call method weblogic returned not null number n (always same) , causes creation of n instance of xatransactionid object. after investigations, found weblogic stores default transaction logs tlog in filesystem , can changed persisted in db. thought there problem in tlogs bei

first off i'm not totally sure if "texture masks" correct term use here if knows please let me know. so real question. want have object in gamemaker: studio moves around it's texture changes depending on position pulling larger static image behind it. i've made quick gif of might like. it can found here another image might explain "source-in" section of image. this reply same question posted on steam gml forum mrdave: the feature looking draw_set_blend_mode(bm_subtract) basically have draw onto surface , using code above switch draw mode bm_subtract. rather drawing images screen remove them. draw blocks on background , remove area. can draw put on surface onto screen. (remember reset draw mode , surface target after. ) its hard head around first time, isn’t complex once used it.

i don't understand str.format_map(mapping) method. know similar str.format(*args, **kwargs) method , can pass dictionary argument (please see example). example: print ("test: argument1={arg1} , argument2={arg2}".format_map({'arg1':"hello",'arg2':123})) can explain me difference between str.format_map(mapping) , str.format(*args, **kwargs) methods , why need str.format_map(mapping) method? str.format(**kwargs) makes new dictionary in process of calling. str.format_map(kwargs) not. in addition being faster, str.format_map() allows use dict subclass (or other object implements mapping) special behavior, such gracefully handling missing keys. special behavior lost otherwise when items copied new dictionary. see: https://docs.python.org/3/library/stdtypes.html#str.format_map

i have following code: class cevent { public: cevent(std::string const&) {} }; std::unordered_map<std::string, cevent> m_messagelist; cevent& getmessageevent(std::string const& name) { auto = m_messagelist.find(name); if (it == m_messagelist.end()) { auto pair = m_messagelist.emplace(std::piecewise_construct, std::forward_as_tuple(name), // copy-construct 'name' key std::forward_as_tuple(name)); // construct cevent in-place name return pair.first->second; } return it->second; } ( live sample ) i think code pretty clean, don't have find separate emplace . there way better? or "good enough"? know call emplace instead of find first, accomplish both tasks, means creating cevent every time, if no real insert happens. once c++17 released (or if compiler supports prerelease versions), return m_messagelist.try_emplace(name, name).first; should trick.

when designing rest-ful api, need handle client connectivity status? for example: in android, user wants send billing details email. clicks "send" button, app goes call api endpoint. @ point before api returns response, app loses network connectivity. meanwhile, transaction on server-side (sending bill details user's email) done. user doesn't know , clicks "send" button again. later when checks email, there 2 emails billing details. now understand transactions such shopping basket, client needs include transaction id in request body make idempotent. but, need use method other api calls?

utilizing following adwords script export bigquery, bigquery.jobs.insert causing script terminate due "empty response". reason call not getting response? var accounts = ['xxx','xxx']; var config = { bigquery_project_id: 'xxx', bigquery_dataset_id: 'xxx', // truncate existing data, otherwise append. truncate_existing_dataset: true, truncate_existing_tables: true, // reports google drive. write_data_to_drive: false, // folder put intermediate files. drive_folder: 'adwords big query test', // default date range on statistics fields retrieved. default_date_range: '20140101,20140105', // lists of reports , fields retrieve adwords. reports: [{name: 'keywords_performance_report', conditions: 'where impressions>0', fields: {'accountdescriptivename' : 'string', 'date&

i'm trying return float x, y , z angle values body object ode (open dynamics engine) simulation. float* creature::eulerangles(const float &q0, const float &q1, const float &q2, const float &q3){ float angles[3] = {atan2(2 * (q0*q1 + q2*q3), 1 - 2 * (q1*q1 + q2*q2)), asin( 2 * (q0*q2 - q3*q1)), atan2(2 * (q0*q3 + q1*q2), 1 - 2 * (q2*q2 + q3*q3))}; return angles; } because dbodygetquaternion returns 4 const float quaternions need rotations , i've had immense difficulty trying compile. compile i'm getting warning. could explain me why , means please? float angles[3] = { ... }; defines local array. the statement return angles; returns pointer first element of array. however, array destructed function returns. hence, returned pointer dangling pointer. that's compiler warning about. if dereference returned pointer in calling function, invoke undefined behavior. in order retu
