What is the meaning of isWriteable?

[Beatrix_Willius]

I have a user who is trying to open a file and the IsWriteable check is failing:

if theFolderitem <> nil and not theFolderitem.IsWriteable then globals.theErrorLog.DialogErrorProceed Replace(kReadOnly, "<<name>>", theFolderitem.Name) Return nil end if

He says he checked the permissions and everything looks okay.

When checking the documentation for isWriteable I’m not sure if it tells me anything:

Even if IsWriteable is True, an attempt to write may fail for other reasons, such as coding errors or insufficient disk space for the information to be written. For example, a write may fail because disk space runs out midway through the write operation. IsWriteable is not intended to check for that condition. If your intention is to write to a file, you should simply attempt to do so.

Is IsWriteable something meaningful or not?

Then I wanted to add a permissions check with PermissionsMBS but this fails completely.

Sounds like your application doesn’t have permission to access this file. Is your application Sandboxed? How are you receiving the file?

[Beatrix_Willius]

The application is not sandboxed. The file is created by my app. I’m not sure if I can trust the user with the permissions.

Hi Beatrix,

You want to open the file to write in it ?

I also had trouble to understand the if line in the code (Not Nil And Not Writeable ?).

Too early in the morning (for me) ?
