How to hide files with Autolisp

[Anonymous]

I used Autolisp to export block attributes to text files.

And I want to hide these files when creating them with Autolisp.

I can't find related code.

Any information is grateful.

Thanks.

Canaan.

You can use DOSlib for that.

(dos_attrib [filespec [bits]])

filespec

The desired file or files. filespec can contain wildcard characters ("*" and "?"). If filespec is not supplied, it is assumed to be *.*.

bits

A bit-coded integer identifying the desired file attributes to set. Specify more than one file attribute by adding the following bit values:

0 (bit 0) Normal

1 (bit 1) Read-Only

2 (bit 2) Hidden

4 (bit 3) System

8 (bit 4) Archive

I'm not aware of any other way

You don't need dos_lib for this. Just use the following function (don't forget to double backslashes in the file path):

(defun hidefile (fname / filobj fsobj)
 (setq filobj (vlax-invoke (setq fsobj (vlax-get-or-create-object "scripting.filesystemobject"))
                           'getfile
                           fname))
 (vlax-put filobj 'attributes (logior 2 (vlax-get filobj 'attributes)))
 (vlax-release-object filobj)
 (vlax-release-object fsobj)
 (princ)

Hiding files is generally a no-no in software design.  It makes clean up and management difficult and can lead to other problems.  Please google 'Sony DRM rootkit' before proceeding.

Although I almost didn't answer the question, from a ethical point of view (I can't think of any normal reason to hide a file with extracted attribute values, sounds fishy to me),

You however are taking it way over the top. I realy don't see how hiding a tekst file has ANYTHING to do with the stuff Sony pulled. If you do, would you please contact Microsoft about "AppData" and a ton of other hidden files & folders?

I'm going to ask the  same question as the others. Why hide it? 

Hiding the files means "no one else should be able to see" the files?  But still accessible only to your program?  

If a program is not prompting the user as to where the data would be exported, the program  can very well save the data to any folder and no one would know. No point of changing its file attributes to hidden or what not.

Can you clear this up for us if you dont mind @Anonymous
