node.js addon - how to pass a string parameter to (nan) C++ -

-

my node.js code :

var mymq = require( './build/release/mqconn' ) ; var myqmgrname = 'qm_cnt' ; // req.params.qmgrname ;  mymq.connect ( myqmgrname, function ( err, result ) {

and c++ code (uning nan) wants receive first string parameter :

nan_method( mq_connect ) {      nanscope();     local<value> szqmn( args[ 0 ] );     printf( "(cc)>>>> qmn [%s].\n", szqmn ) ;

... garbage.

any clue on doing wrong ? sebastian.

first should validate arguments. can string calling tostring() on argument. example:

nan_method(mq_connect) {   nanscope();    if (args.length() > 0) {     if (args[0]->isstring()) {       string::utf8value str(args[0]->tostring());       printf("(cc)>>>> qmn [%s].\n", (const char*)(*str));     }   }

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens ...
