i want to make a winfx application.

mean to say that i have windows7.

i want to lock the specific folder using c#, WHEN user double click on folder icon then a pop up or dialog box should be displayed which ask from user wheather to make password or not?
if user say yes then ask the password and do it. when user try to re open it again then it should display a dialog box in which application asks the password from user , if user type it correct then unlock the folder otherwise not open and remain locking.

You would be better off in my view clicking the WindowsClient logo at the bottom right hand corner of tis page and asking your question in that forum.

 thanks
