Folder Permissions

[Graham]

Is there a way to change folder permissions programatically. I need
to grant full access to two folders (which are subfolders of my
program directory) as shown below

c:\My Program File\tempzio
and
c:\My Program File\Move

Currently I delete files in these two folders on program exit, which
is fine on XP but both Vista and 7 require explicit permissions.

Are the files temporary files? Create cursors instead of .dbf
files, etc., or create the files in a temp directory.

exit.

So what I should do then is reference the windows temp folder and
unzip the file to there?

"lctempfolder=sys(2023)
lcfiletounzip=addbs(lctempfolder)+file to unzip"

Do Vista and Windows 7 allow you to delete from the temp folder or is
that something that the OS looks after for you.

Thanks for your help.

I have not had to deal with it myself, but later versions of
Windows are sticky about where you can write. "\Program Files" is one
of these.

That is one possibility. Another is to create a temp directory
elsewhere.

I do not know. I do not see why you should be prevented.

...or maybe call the old DOS "attrib" command as in "attrib -r" to
remove read-only.
That's all I got, but maybe someone can make it more complete?

Thanks Gene but the program directory is actually off of the root
drive

i.e. c:\ProgramName
and the two other directories are subdirectories of the above.

I think the idea of using the GetTempPath a great idea.

But I am intrigued by John3's idea, if indeed permissions is based on
the attrib
flag of a file.

Pardon me. I misread.

That is just a simple and early permission that dates back to
MS-DOS.

While I have not looked into it, you should probably try
searching on "Windows ACL" or "Windows Access Control List". An ACL
is one way of implementing permissions. For example, you can say to
allow user foo to read a file but not write it and give user bar read
and write permission.

I'll look into the Windows ACL

Thanks Gene
