Hi:
Ok, I'm trying to use boost::asio::io_service::run as follows.
At the top of a .hpp file I have:
typedef boost::asio::io_service FolderMonitoringService;
I can pass this to a constructor requiring an io_service as follows:
boost::asio::dir_monitor dm(FolderMonitoringService);
however when I try to do:
               FolderMonitoringService.run();
I get 2 c2143 errors.
     1>d:\work\access for everyone\sibelius access\sibeliusaccessserver\utility.cpp(127): error C2143: syntax error : missing ';' before '.'
     1>d:\work\access for everyone\sibelius access\sibeliusaccessserver\utility.cpp(127): error C2143: syntax error : missing ';' before '.'
If I remove the typedef previously shown, this line:
               FolderMonitoringService.run();
Compiles fine, but the line:
boost::asio::dir_monitor dm(FolderMonitoringService);
will not compile giving c2061, solved with the typedef-thanks igor!
I've tried boost.ref, with know success.
The function signature of the dir_monitor's constructor is:
    explicit basic_dir_monitor(boost::asio::io_service &io_service)
Dir_Monitor is typedef'd to be basic_dir_monitor.
Can anybody please tell me why the run function is causing an issue and how to fix this issue.
Regards
Sean.
