Checking if a file exist

[batels]

Hey All,
I'm a bit new at this,and i tryed seraching google about it but i
didn't quite got a solution.
I'm writing an HTML page that needs to check if another html file exist
(in the same folder) and if not,to call to a C file and create that
html file.
I tryed to do that with JavaScript but i understood there is no such
option.
Can u advice?
and once i know that file doesn't exist,can i call to a C file from a
simple html page?

Thanks a lot!

[We didn't do anything yet, so why the thanks.]

If you are talking javascript in a browser on a page from a server on
internet, the js has no security clearance for files on the client.

Javascript on a local .hta file or in wscript is a different matter.

The same goes for serverside javascrpt [on an ASP platform]

Which of the 4 is your Q about?

I'm writing an HTML page that needs to check if another html file exist

HTML is a data format, it can't "do" anything.

(in the same folder) and if not,to call to a C file and create that
html file.

Call to a C file? Do you mean "execute a binary created by compiling
source C source code"?

I tryed to do that with JavaScript but i understood there is no such
option.

Client side JavaScript runs with very low permissions. Its almost
certainly the wrong tool for what you are doing.

Can u advice?

It sounds like you need to set up your webserver so that when a file is
requested, it checks to see if it exists, and if it doesn't, create the
file and then returns the result.

Apache is the industry standard webserver and certainly has this
capability. I'd get a copy of the Eagle book if I were you, it goes
over how to do this sort of thing. (It should be a fairly simple
content handler).

Thanks for the quick response.
by calling to a C file , i did mean to execute a compiled source code.
i'm writing a program that generates these html pages,do i still need
to look at the Apache? I meen,i'm not creating a website or anything
like that...

Compiled sourcecode is not sourcecode anymore. You mean executable?

Please first answer my Q on what platform.

All local. JavaScript on a local html page

 

[batels]

It all depends on what news-reader you use
[xnews. agent, outlook]
or perhaps a web-news form, like Google groups.

You can easily educate yourself by looking at
other usenet postings and reading about usenet-netiquette.

Is it Ok now? i just wasn't enrolled to the group

Compiled sourcecode is not sourcecode anymore. You mean executable? Yes,i meant executable.
Please first answer my Q on what platform.

Everything i use is local. I need to write an Html file (call it #1)
that
searches for a different html file (call it #2) that exist at them same
directory. if it exist it creates a link to in,and if not i should
execute a C file that will generate the #2 file.

My probem is - i don;'t know how to search for a file (tryed
JavaScript,didn't work) and how to execute a file from Html.

Thanks ! i hope i post it correctly this time.

Yes,i meant an executable file.

Please first answer my Q on what platform.

Everything i use is local. I need to search for html file #2
which is at the same library as html file #1.
if the html file #2 doesn;t exist,the html file #1 should excute a C
file
to create it.
Thanks,i hope i post is wright.

Basically, I don't think Javascript is the right tool for solving your
problem. Unless there are other reasons why this *has* to be done in
Javascript, your best bet is to use a script running on the server written
in PHP or Perl or some such thing.

Thanks! it doesn't have to be JavaScript. I'll try to investigate
PHP,since
i'm not familiar with that.
Just one last thing,can i write a script in PHP that searches and
execute files
that are on my local pc and not saved on a server?

Before posting to a group, you should look round. There is a FAQ
posting three times a week, in two parts. Read both parts.

<FAQENTRY> To reply in Google, use Show Options then its Reply.

No, you can't --- PHP scripts run on the server.

Rubbish. PHP is but a programming language, it can run both
client-side and server-side. And so is and does J(ava)Script.

From someone with a (here discouraged) PGP signature one would expect such
basic knowledge. The signature itself is broken, though; it has to be
start with a line containing only "-- " to comply to Internet standards,
and it is recommended to keep it short (4 lines or less is quasi-standard).

Evertjan. I am startled by how rude you are.

Obviously this person is a newbie and is 1) appropriately asking for
advice 2) stating what he/she has already done to look into the problem
3) thanking the group for any assistance they may provide. Your response
on the phrasing of the "Q" was neither helpful nor friendly.

Why would you respond in such a nasty manner?

You stated: "This is not sms, please use only usenet abbreviations. " If
you persist in thinking that this newsgroup is only available through
old-school programs or quasi-usenet through Google that provide a proper
quoting method, then you are denying the repurposing of information on
the Internet. I am currently replying through a textbox at
http://www.developersdex.com. There is no quoting, just a textbox.
(technically, a textarea, since you seem to be hung up on
technicalities) You're right, this is not sms, but it's not really
usenet either anymore, when I'm getting the information from http and
replying through http.

Likewise, your "replace all crosses…" statement is useless, because this
web page does not show your email address at all. Should I consider you
as stupid for your ill-advised tagline instruction?

The phrase is: "If you can't say something productive, keep your
friggin' mouth shut."
With that in mind, I will productively tell you to please refrain from
bashing someone when they are simply looking for help. You are not
helping.

Thanks in advance, <-- certainly in advance, since your first post
snidely said, "[We didn't do anything yet, so why the thanks.]"
Apparently "common courtesy" is not in your usenet vocabulary.
