Sir, I want to know that how folder locks program works....e.g. they lock the folder in such a way that a password is attach to them and no one can access them from command prompt, Mycomputer or address bar or RUN box or any.... Plz tell me i want to develop a simple software in VB.net of such kind as a requirement for my own Institute... and dont want to download ready made one. Plz tell me their way of functionalities and flow then finally give me a simple touch for programming in VB.net. I really appreciate ur responce!! Thanks in advance!! Syed Fahad Hussain

It's a pain. First, it cannot be a "real" directory, as there's no way to password protect a folder. Second, you need to employ encryption so people can't just bypass your program to get at the data. Finally, you need to make drivers so they'll appear as real folders to the GUI. It's not something you can whip up with VB during lunch.
