And now, you have not written to my hard drive. Try again :)

Nobody ever doubted this. In fact, this has been mentioned at least by me
several times before. However, the script needs the privileges, and it
can only get the privileges if it is signed, or, if it is not signed, the
security settings of the client are reduced, which opens a security leak
for all other Web sites.

Hi Folks
This is probably starring me in the face but how do I read the contents
of a hard drive directory? I've been playing around with the
opendir($dir) sample from php.net and can read from the server without
problem but how can I read a list of files from the hard drive of the PC
(win98 (spit!)) I'm using? Basically what I want to do is read the file
names of a certain directory on the hard drive into an array and then
upload them...

I have a web app that needs to parse through a file that is located on the

It is working fine on my development box but when I put it out on the test

I am essentially taking the query string & using a stream reader to read the
file.

My problem is that I don't know what to do now! I tried declaring an object of my...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
