File locking

[Jean-Luc Arnaud]

Hi all,

Is there a way, with a Xojo, Shell or MBS command, to lock a file in
order to make it not writable, read-only?

I know some Shell commands on Mac modifying authorizations, but I'm
loocking for a kind of "Lock" in Macintosh File Info or "Read Only" in
Win file properties.

Thanks for your help.

Hello Jean-Luc,

Are you not simply looking for the Locked property of a folderitem?

Hi Arnaud,

Yes ... and no!

I not only need to know if a file is locked, I need to be able to
lock/unlock it.

On my first coffee but, assuming folderitem.locked is a read-only property
(I'm not 100% sure about that): couldn't you use a shell/path to 'chmod'
(or equivalent) the file permissions?

Yes, sure. I was hoping not to have to code this way. No matter...
For Windows, 'attrib' does the job.

Hello Jean-Luc,

What’s wrong with setting the locked property?

It's Read-Only, unless I'm wrong or we don't talk about the same property.

It’s definitively working on my side.

Does this code compile for you?
dim f As FolderItem

f=SpecialFolder.UserHome.Child("SomeFile")

f.Locked=not f.Locked
Return True

I mean, except the “return true”, of course.
If it compiles, then it’s not read-only on your side either.

And you're right, of course, Locked is not a read-only property, but
actually a R/W one.

Ok, Arnaud, we don't talk about the same property, I was thinking to
'IsWriteable'.

I didn't know 'Locked' and looked for 'IsLocked'! What a stupid guy!

Thanks for your code sample, I have to test that because a file may be
locked by itself or located on a locked volume.

Thanks again.
