So use a global variable.

You are the boss of the code, aren't you?

===

var oFLTimeout;

HControl.protot ype.setFLTimeou t = function() {
oFLTimeout = setTimeout("hCt rl.mkView.reloa dFL();", iFLTimeout);

No, I'm not!

Perhaps I wasn't clear enough, I said "online webpage" in other words I'm
downloading the page and its scripts and I want to inhibit/change the page
refresh timer.

Thanks

Indeed you were not very clear.

So open the page,
go to view source,
change the code and save the local file,
then execute this local file,
if necessary after adding:
<base href="http://the original url here"> in the <head> section.

Stop trying to cheat on whatever timed test it is
that you're trying to hack.

Well I'm still not being very clear:)

I want to download the web page into my browser control.
I want to then execute a "function" within my MFC program through the
script interface which will allow me to "automatica lly" adjust the refresh
rate by altering the script function dynamically.

If the timerID is a global variable I can do it.

However as it is a local variable I can't.

"Manually" changing the page scripts isn't an option.

Thanks Lee, very useful. Of course, I'm not "cheating" anything.

Have you any constructive comments to make which might actually help me out?

What is a "browser control"?

Changing the page by script should be possible.

I suppose you want to do some data mining.

Like this?

function getUrl(url) {
var http = new ActiveXObject(" microsoft.xmlht tp");
http.open("GET" ,url,false);
http.send();
return http.responseTe xt;
}

When the content of the file is in a local variable as a string,
you can replace parts of that string with multiple regex replace.

t = getUrl('http://yourTargettedWE Bsource.com/')

t = t.replace(/;HControl.proto type/,
'var oFLTimeout\n;HC ontrol.prototyp e')
t = t.replace(/var oFLTimeout/,'oFLTimeout')

After that you can execute the string as if it were a http file.

[How? I have to think about that ;-) ]

You're welcome.

It's not your page. Somebody put a timer there for a
reason. You're trying to change it. That fits my
definition of cheating.

If it happens not to be a test, posting a solution (if
one existed) would allow others to cheat on such tests.

So you're posting smart-arse comments from baseless assumptions when you
have no idea at all why I want to do what I'm asking.

That fits my definition of a ******* ******.

Have a nice day.

Microsofts WebBrowser Control.
By downloading a page into that I can get "programati c" access to the
documents properties and objects, scripts etc and do some "bespoke"
operations on them (hopefully) such as altering the refresh rate. It also
allows you to execute javascript functions - "standard" such as
ClearTimeout() and user defined, but as the timerID is only defined locally
in the prototype settimer function I gave in my initial post I can't find
it.

Here's a refrence if you're interested:

Sort of.
But really I don't want unecessary refreshes clogging up bandwidth. Also any
solution might help me learn a nice way into the scripts.[color=blue]

Maybe. With a webbrowser control its possible build that text as a function
and execute it as javascript. I'm sure you can in other languages but I'm
familiar with MFC (not an expert with the WBC or javascript though).

For instance I've managed to alter the timer rate and set up a new timer for
the page.
However, all this does is add a new timer in addition to the old so I end up
with both timers refreshing the page.

OK. Whatever ideas you may come up with I will obviously have to convert to
run in the WBC but thats my problem ;) - I just need a way forward.

Will the timer be prevented from running by changing the text, given that
the script may have been executed and the timer set up before the text is
altered?

I'm not sure how I can change any script after it is downloaded but before
it runs in a WBC. If its possible then I could just change the timer delay
variable to be whatever rate I want - although this would then be fixed for
the life of the WBC.

An ideal solution would be to delete the existing timer so that I can set up
a new timer to refresh at any rate I wish.

But any ideas appreciated.

I recommend changing the content of the page by intercepting the download
of the page, and then change the page before giving it to the control (if
intercepting is possible). You can then change the page to make the local
variable global, or something else.

Correct.
[color=blue]
> "Manually" changing the page scripts isn't an option.[/color]

Are you sure? It could be easier.

Also, getting the id of the timeout won't help you a lot anyway. All
you can do is cancel that one timeout. A better way would be to
replace the "setTimeout " with your own version, that calls the
original. Something like executing this script:

---
var oldSetTimeout = setTimeout;
var myOverrideTime;
var myLatestTimeout ;
setTimeout = new function(arg,ti me) {
return (myLatestTimeou t = oldSetTimeout(a rg, myOverrideTime || time);
};
---

Good luck

What part of my comments qualify as "smart-arse"?

No, you don't seem to read well. I do have a base for my
assumptions. You're trying to change the functionality of
somebody else's web page. That a pretty substantial base.
If you've got some justification, it's up to you to present
it, if you expect help.

I've also said that completely regardless of why you want to
do what you're asking for, it would be irresponsible to post
a solution (if one existed).

Hello Lasse.

I've been investigating this for some time but haven't found out how to do
it through a WebBrowser Control - of course doesn't mean it can't easily be
done ;)

Well, depends on what one means by "manually". I want to run the program
automatically without having to be present.

Again, this is dependent on me being able to change the scripts before
execution which I'm trying to work out how to do.
