Hallo Ion,

thanks a lot for your help! Your suggestion works brillant. but is a 
littel problem:

By start my application throw the visual studio 2 exceptions:

First-chance exception at 0x7c812afb in WindowsDataCollector.exe: 
Microsoft C++ exception: boost::interprocess::interprocess_exception at 
memory location 0x00efe5d8..
First-chance exception at 0x7c812afb in WindowsDataCollector.exe: 
Microsoft C++ exception: boost::interprocess::interprocess_exception at 
memory location 0x00efe58c..

but the application works without any problem. is that normally?

Thanks again
Best regards
Ming
