windows - Program management, according to whether it was started directly or with another file by dragging its icon. (batch) -


when start batch file double-click, in variable %1 echo off. when start batch file, file (drag&drop) batch file icon, in variable %1 contains path file started with.

i need thing: program start when in %1 echo off. goto when in %1 else, goto b

i tried many potetial solutions problem, of thin doesn´t work. tried find , findstr , 1 of combination of for. have feeling impossible in batch.

you don't echo off inside %1. when double click batch file there not arguments, %1 empty , echo %1 parsed , converted echo (no arguments, no value echo) , when executed without parameters echo shows current echo status.

for start point can use like

@echo off     setlocal enableextensions disabledelayedexpansion     if "%~1"=="" goto :eof

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()...

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...
