I thought the daemon would create the pid file. but however i get this  
strange error.  
require “Daemons”  
options = {  
:app\_name =\> “my\_app”,  
:ARGV =\> [‘start’, ‘-f’],

# :dir\_mode =\> :script,

```
:dir => 'pids',
:multiple => true,
:ontop => true,
:mode => :exec,
:backtrace => true,
:monitor => true,
:script => "E:\\TradingTools\\Development\\app\\helpers\\"

```

}  
filename=“E:\TradingTools\Development\app\helpers\twsMonitor.rb”  
Daemons.run(filename, options)
