Lock And Unlock multiple Directories

[danecook21]

Honestly I don't really know what this "locking" is but I can see the problem. Only one is unlocked because you are Closing the handle to hDir. hDir is set to the last CreateFile return value that you got from clicking the mnuBlock. So it's only applying to the very last one. You will need to save all these handles so you can close them all.

Edit: It looks like you are "locking" the files by literally having the OS lock access to them because there is an open file handle. If you are doing this for security, that is a very poor way to handle it. File security should be handled by either encrypting the file, or by higher level user access control.
