Dependent Visa work related query

Hi,

Me and my wife are Indians. She will be going to Brussels,Belgium for a project from her current company in India to her client location in Brussels. She would be getting a Work Permit B. Also we would be applying for dependent visa too for me. I am a software developer in India. I wanted to know 1) If I would be eligible to work in Belgium on my dependent visa by default ?
2) If not , what do i need to do to so that I can also work in Belgium ?

Regards,
Guru
