Is there a way to open file for writing so that the opening
fails if the file already exist? This needs to be atomic
operation so that it is possible to use the file as a
semaphore. As a result, the following coding does not do:
if (!file.exist()) {
// open the file for writing
...
A similar function definitely exists for accessing files in

could someone give me some advise on a problem I have. At present i have a
web application which displays pdf files in a web browser using javascript
and the window.open method and pointing to a web address like
window.open(http://.........).
I have been asked to find out if it is possible to do something similar but

Hi all,
I want to put a button on a page, and when the user clicks it, the standard
Windows "Open File" dialogue box opens, and the user can browse/select a
file on their PC. Having selected a file, the user clicks Open, and I then
want to capture the file path and name in a string variable. Finally, I
want to upload the file to the server.
BUT: I don't want to use an <input type="file"> control.

Hi
I have my home directory on my departments server. Somehow I am not
able to write to a file using a php code,
$myFile = "trial3.txt";
$fh = fopen($myFile, "a+") or die("can't open file");
Instead of a+ if i use r or w or anything, it does not work. Could this
be a permission thing? The entire directory had a 777 permission and
even i after i created a file and chmod'ed 777 to it, the code couldnt
open it. What could be the matter?...

Hi. I'm writing an archival system which I'd like to be portable
to Windows.
The system relies on the property of Unix which allows a
process to keep a file open even if another process renames
it while it is open. Neither process sees any anomaly or
error.
Do the NT file systems support this feature (which I think is
standard for POSIX systems)?

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.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
