How could I lock any file in my PC from others access?

[sayeedbd]

Hello All,
I am trying to lock some my video, picture, Excel and Word file in my PC by using Visual Basic. I am using Visual Studio 2008 to develop this application but I am unable to do this job.
It'll be something like security utility application. Actually without me, some other people also using my computer and I am trying to lock their access in my personal file.
Can anyone here help me by providing me the Particular code for it? And I wish to know the tools which I can use for this job. I am just a Beginner on this development field. Please help me. I wish to lock individual files in a PC.

Thanks

Doing it in VB.NET is going to be really hard.

You can use this good tool instead of making your own:
