Topic: deleting files via lisp

[vinnyg]

Is it possible to delete a file from any directory using lisp?

If so, how can this be accomplished?

I'm new at lisp, so any info regarding a procedure like this would
be helpful!

Thanks

[Craig]

Yep, you sure can
(vl-file-delete filename)
There will be many more post coming soon and I would really love to start something for you but I am in the middle of a project of my own so just hang in there.

How about this

Code: [Select]

(vl-load-com)
(if (setq fn (getfiled "Select File To Delete" "" "" 8))
    (if (vl-file-delete fn)
      (alert (strcat fn " Deleted..."))
      )
   (princ)
    )

Vinny,
What version of Autocad are you running? The routine Mark posted will only run in 2000+.

[Craig]

Mark, if this runs on its own merit when pasting it on the command line, why in some situations you have to have (vl-load-com) at the start of the program to make it work

[Mark]

If you have loaded a program that has (vl-load-com) in it, that will work for the whole ACAD session.

Looks like I'm in violation of the Daron Act.
let me go edit that post real quick before Daron see's it

[Craig]

So what you're telling me is I could possibly have Autocad load the (vl-load-com) automatically at the start of a new session

[Mark]

sure, do you a custom menu, put (vl-load-com) in your .mnl file. Or any other lisp that runs when ACAD opens.

[Craig]

So, have you figured out a way to make mutliple selections in a DCL file list box like such

Code: [Select]

: list_box {
            key = "box_list";
            fixed_width = true;
            allow_accept=true;
            alignment = centered;
            width = 40;

I know how to get single selections but not multiple. Any ideas?

[Craig]

Or, is there a vl- comparible to getfiled that will let you select multiple files?

[Mark]

multiple_select = true-false;

Specifies whether multiple items in the list_box can be selected (highlighted) at the same time. Possible values are true or false (default: false). If true, multiple items can be selected at a time.

that should work in your DCL.

[Craig]

Damn, where the hell did you run across that. I have been looking and found nothing. You got a book or something?  

Thats exactly what I was after. You are my hero!
