Hi All,
I am a newbie to DHTML.
Is there any way to communicate from C to DHTML and vice-versa?. Like Swig which will communicate from C to PHP and vice-versa.
Awaiting for the replies.

Malar

I don’t know what you need that for, but I think you would have to make an AJAX call to a script, where you can run C in.
Hi Dormilich,
I am using a web server where the DHTML pages will be placed and on demand the pages will be rendered dynamically. The functionality is coded in C. I want to communicate the result from the C to the DHTML pages.
Is it possible with ajax call ???

Malar

could you explain that a little more? if it only is server to client communication, the matter could simplify a lot.
Hi Dormilich,
I have to place my DHTML pages and the C code in the embedded linux. When ever a request is made from the client, C code will get the necessary details and have to give the details to the DHTML pages.
Also the details from the client i.e., from the DHTML pages have to reach the C code and necessary changes have to happen.

Malar
I'm not sure what you mean by dhtml pages having to reach the c code except, perhaps, you mean you need to interface some language like php or python to some c code elsewhere. Most scripting languages like those have a c interface but you'd have to look at the documentation for your language.
If, otoh, you are trying to create dynamic (dhtml) web pages using C then, yes, I do it all the time.
What MalarN wants is, the Target device is some embedded device running on Wind river OS. The device functionality is written in C. Now they want to provide the web interface for that device. So they were hoping to do that using PHP. But to serve the pages PHP(Parser) need to be in that device along with some web server, to achieve this cross compiling the PHP source is necessary, So to avoid it they are thinking of achieving it using dynamic HTML.... @drhowarddrfine
Interesting.... How you do that...I want to learn.....?

Dynamic HTML means the page are created on the fly as they are being served so some programming language will be required no matter what. As far as servers go, you wouldn't need Apache but he could use something lighter like lighttpd or even lighter ones like thttpd and others.
Or avoid server software altogether and program straight to sockets.
Creating web pages using C is not significantly different than any other language. The compiled executable is placed in the bin directory of the server and it gets called like any scripted program. I've even done it in assembly before.

Thanks Doc :)
I was thinking about a hypothetical device that would service webpages that report the status of the device (along with other self diagnostics details) and also lets users change the status of the device (and do some other basic, low-level functions)....p retty much develop a "thin-client" for the device.
I was curious to see what types of embedded HTTP servers were out there to help with the task.
Although I'm not sure if this is going to be the best approach for my system requirements... I'm going to look into your recommendations .

Hello,
I am finishing up creating a fairly complex page that is very rich in
DHTML. In addition to updating it self every couple of seconds,
various components on it support sync and async communication with
various web services.
The problem is that if a user tries to click on any JS driven content
before the page is fully loaded, it will not work properly since it
relies on many onLoad scripts that initiate webservices etc.

hi there,
i would like a book that will explain concepts of javascript and dhtml
instead of, for example, ten tutorials on how to do specific things in
js or dhtml.
ideally a book thats can explain from the basics of javascript, to
more complex things such as dhtml and dom onto things like creating
javascript objects (if that is possible, but u get the idea). rather
than this is how you make a drop down menu tutorial; this is how you

Hi;
I have heard about a few very good books on DHTML, but the most modern
ones seem to have been published in 2002.
Have any _significant_ changes in DHTML or the standard DOM happened
since then or will those "best of the dhtml books" still do the job?
If not, is there a place on the web that documents DHTML, well, in its
latest greatest form?
