Device (PORT) Locking using C/C++

[santoshthankach]

Hi All ,

I have a requirement of developing an application which can control the hardware devices like floppy drive, CD-ROM, Printer, USB port, COM Port etc.

This Application depending upon some access privilieges of the user logged into the system, will lock or disable the devices which that particular user is not authorised to use.

I need some kind of sample code which can demonstrate doing something like this, or Some web links that I can surf to get more ideas or some articles which can route me to proper direction for developing this application.

Please do provide me your suggestions as to how shall I go about this at the earliest ?

Thanks in advance
