Methods and Timer in C# -


when debug small program step step f10 button, program rational until reaches level timer.elapsed +=. after supposed go call method check(myconn) doesn't! goes myconn.close(); , bounces between these two, closes program of sudden!

i wondering issue comes ... line: timer.elapsed += (timersender, timerevent) => timer_elapsed(timersender, timerevent, myconn);? solution posted on forum in case wanted give in argument myconn timer_elapsed ...

thanks in advance help!

static void main(string[] args) {     // create connection     string connstr = "provider=microsoft.ace.oledb.12.0;data source=c:\\users\\mike\\documents\\database1.mdb;";      oledbconnection myconn = new oledbconnection(connstr);     myconn.open();      inittimer(myconn);      myconn.close(); }  static void inittimer(oledbconnection myconn) {     //set timer     timer timer = new timer();     timer.interval = 2000; // check every 2s (2000ms) if values in database changed     timer.enabled = true; //enable timer, when timer elapses after 2s, performs calculations      timer.elapsed += (timersender, timerevent) => timer_elapsed(timersender, timerevent, myconn); }  static void timer_elapsed(object sender, elapsedeventargs e, oledbconnection myconn) {     check(myconn); // check method have in program takes argument "myconn" }

after set timer, code continue running. leave inittimer method , close connection. after that, main function exit causing application close. timer terminate then.

in case program not being terminated, timer counting down 2000. when reaches zero, fire event. happens on thread , happens parallel main theat. check connection, obiously closed.

if want main threat wait till event fired, why use timer @ all? why not this?

static void main(string[] args) {     // create connection     string connstr = "provider=microsoft.ace.oledb.12.0;data source=c:\\users\\mike\\documents\\database1.mdb;";      using(oledbconnection myconn = new oledbconnection(connstr))     {         myconn.open();                 {             thread.sleep(2000);              check(myconn);           }         while(somevaluetoindicatetheapplicationcanterminate);     } }

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

java - Are there any classes that implement javax.persistence.Parameter<T>? -

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
