Well, you've asked a rather broad question that cannot possibly be answered fully in 1 post. There is huge amounts of information online about the Hypertext Transfer Protocol (HTTP) which is what you are after.
In brief, a web browser works along these lines:
1) User types a URI in the address line, or perhaps clicks on a URI.
2) The browser sends a request to that URI for the content.
3) The content is returned to the browser
4) The browser attempts to parse and display the returned data.
It is this request-response mechanism that makes the web work.
One of my favourite websites for this sort of thing is www.howstuffworks.com

This page is displayed as a popup window on the click of a link, and there is also a print button on the popup window. I want to show a print dialog which should inturn print the page but not th button.
I have placed all the thinks in two different Div Tags (Forst div for buttons and second div for Content).
A peice of code snipped will definately help more to achive it.
Thanks in advance.

script.js
function getPrint(print_area)
{
//Creating new page
var pp = window.open();
//Adding HTML opening tag with … portion
pp.document.writeln('<title>Print Preview')
pp.document.writeln('<base target="_self" />')
//Adding Body Tag
pp.document.writeln('');
//Adding form Tag
pp.document.writeln('');
//Creating two buttons Print and Close within a table
pp.document.writeln('');
//Writing print area of the calling page
pp.document.writeln(document.getElementById(print_area).innerHTML);
//Ending Tag of , and
pp.document.writeln('');
}
*****************************************************************************
NOTE:
I was facing problem during print. Print was not working when 1st time clicked. I solved that problem by reload
location.reload(true);
getPrint(print_area)Function take DIV Id which section you want
to print. Then, it creates a new page object and it writes necessary HTML tags
and add print and close button and finally it writes print_area
content and closing tag.
And call the following way from the aspx page. Here,
getPrint('print_area') has been added for printing print_area
DIV section. print_area is the DIV id of DataGrid and rest
of two will work for others DIVs.So, whatever areas that you want to print must
be defined inside of DIV tags.
And include Script.js
file in the aspx page.
'calling getPrint() function in the button onclick event
btnPrint.Attributes.Add("Onclick", "getPrint('print_area');")

Hi all,
I have a web application written in c# and I am trying to export an HTML formatted message to Lotus Notes. Here's is the code I am using
SendEMail sendEmail = new SendEMail();
sendEmail.From = "EMailSender@whatever.com";
sendEmail.To = "EMailReceiver@whatever.com";
sendEmail.Subject = "Completed and Scheduled Changes";
sendEmail.Body = sMessage;
sendEmail.Send(sMessage);
The sMessage is in HTML, however that doesn't work.
Any help will be much appreciated
Thanks
Tony

How do you mean with "that doesn't work"? You get an error? The layout isn't what you want in lotus notes? Lotus notes translates the html to text? ...
|
|
|
|
|
I dont get an error but lotus notes does not translate my html. It returns the HTML as it was typed. Like ....etc. What I want is the content of it.
Thanks
Tony

What are the advantages of moving from the traditional table layout style of a web page to the new CSS layout?
Any disadvantages or reasons not to move to CSS?

:: You can make pages with half the code (or less), which gives faster downloads.
:: You can separate the markup from the layout, which simplifies construction and maintanence.
:: Correct usage of html tags makes search engines index your pages better, and makes it possible for disabled persons to access your site. It also makes your page usable with any browser, ancient or future, even if they don't display it correctly.

Table layouts works better with browsers that partially, and inaccurately, support css, like Netscape 4 and contemporaries.

Thanks.
I will take a closer look at CSS. Is Visual Studio 2005 Web Edition editor a good place to start? Or, are there any other editors you would suggest?
|

Visual Studio 2005 works fine to make CSS layouts.
I suggest that you use Firefox to test the designs while working. Visual Studio uses the same rendering engine as Internet Explorer for previews, and IE 6 has some rendering bugs.

Always one to look for an argument, me:
Guffa wrote: :: You can make pages with half the code (or less), which gives faster downloads.
Oh yeah? You can markup a basic header / 3-coloumn / footer page layout using HTML tables in a dozen lines of code. Try doing that in CSS! Au contraire, you can find whole websites devoted to this one signle topic. Or problem, to be more accurate. And the solutions they come up with involve a lot of code.
Guffa wrote: :: You can separate the markup from the layout, which simplifies construction and maintanence.
Oh yeah? How easy is td bgcolor=#cccccc compared to td class=fred now then where is my definition of fred, oh yeas it's in xyz.css which is in abc folder right got that now then where the hell is my fred class... somewhere down at line 533 I think...

OK, I'll give you that - but emphasize the words "Correct usage" - otherwise your page will look a right mess. And don't forget to write half a dozen CSS pages for all the different browsers out there....
But - and it's a big butt (no that's not a typo) - fact is CSS is the way it's going so you - and I - are just going to have to get used to it. And yes, of course I am being a bit disingenuous, because a site laid out with CSS will be much easier to make global changes to; eg, once your client decides they want to re-brand themselves and use orange throughout instead of blue, you'll be glad you used CSS. Site maintenance is easier if you've used CSS, but you need to be organised, and one trouble with CSS is it's inherent lack of internal order. USE COMMENTS EXTENSIVELY in your CSS. The very fact that your markup and your CSS are seperated means you have to keep track of what relates to what in some other way.
Like all web-technologies CSS suffers from the fact that every browser does things differently and while the guardians at W3C like to think they're the arbiters of standards (did I ever vote for them?) fact is we already had a standard - it was called HTML.
Nevermind - hey, I LOVE CSS/XHTML XXXX (Is there an arse-lick emoticon anywhere?) I use it all the time now. (Really, I do.)
Good luck
