Confused about ColdFusion syntax (quotes and pound signs) -


i'm confused 2 different styles of syntax , want know 1 considered programming practise coldfusion.

in first example, returnvariable not using double quotes. nor cfset variable:

<cfinvoke component="#userobj#" method="mymethod"         username="#myusername#"         returnvariable= returnvar><!--- no double quotes --->  <!--- no double quotes & no pound signs ---> <cfset session.userright = returnvar>

in second example, code is using double quotes returnvariable , cfset. first 1 set returnvar while other 1 using double quotes , pound signs "#retunsvar#"

<cfinvoke component="#userobj#" method="mymethod"         username="#myusername#"         returnvariable= "returnvar"><!--- using double quotes  --->  <!--- using double quotes & pound signs ---> <cfset session.userright = "#returnvar#">

it looks can use both styles , either work?

if you're looking programming practice should start not using cfinvoke

if you're on coldfusion 9 or higher can use follow syntax. 

<cfset userobj = new userobj()> <cfset returnvar = userobj.mymethod(myusername)> <cfset session.userright = returnvar>

or can simplify more eliminating setting of variable

<cfset userobj = new userobj()> <cfset session.userright = userobj.mymethod(myusername)>

there no need use " or # when setting variable. recommend not using type of variable named retvar or returnvar or somethingthatdoesn'texplainwhatitis

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
