I was just being wilfully perverse. You both are right of course - it depends on your model.

Obviously a table is more HTML code than just a DIV but provides better layout flexibility.
Actually, there are problems with tables not to mention the hassle of using those 1x1 gifs to blank out cells. Long tables in IE render slowly unless your table contains fixed widths. I just do not know if similar problems exist if you use nested DIVS.

I used to in my earlier days. But after being told enough times that tables are for data not layout it finally started to soak in. DIVs can be a pain to display the same in all late model browsers since they do not seem to have the same rules applied per the CSS standard. But if you stay clear of padding and use more nested DIVs many of the problems clear up. It is nice not to have the need of the 1x1 gif anymore 
My biggest headache has been Mozilla. The browser follows the standard on a couple of issues but does not display the same as Opera or IE. So I always question what the standard should be but code around the issues
Also, as we move on to XHTML, this will become even a more serious point and I figure many will start to move away from tables.

In addition, the table tag is older and is supported properly by all browsers. Of course, now, the DIV is also supported but not fully and properly by older browsers.
That part does not matter in my work anymore. I figure if a person cannot upgrade to a useable browser, there will be more problems than just the browser. I currently code for IE 5.0 or later, Opera 7.0 or later, Netscape 7.0 or later (do not even get me going on thier old garbage) or Mozilla 1.4 or later. Anything ealier than that, people will need to upgrade.

I was not aware of that. But if it takes 1 second instead of 0.5 second, does it really make a difference?

What do you mean? What is serious about XHTML and TABLES?

As I said in the other threads. To some extend I agree with you. Its just a mater of how much time you need to spent on supporting older browsers. You asked asked about DIVs and TABLEs and I gave you my opinion...
I respect your opinion. I might be wrong, you might be wrong... We both made our point.
At the end its what you prefere to use. there are good and bad points for both... I personaly like tables coz I know how different browsers render them and I am very familiar with them. I find it easy to use tables.

I guess it would depend on the content. A few seconds waiting for something to appear on your screen is annoying if you have broadband, but if you are using dialup and it takes 20-30 seconds of a blank screen waiting for content, can lose a visitor quickly.

Well, there is about the same amount of problems with tables, empty cells, borders and nestings. I think one of the biggest problems for me is that even VS.NET does not make working with DIVs as easy as it should. Maybe by VS.NET 2005 we will finally have decent editing 
Coding by hand though, I do like DIVs as it appears much cleaner. Just wish Mozilla handled percentages with DIVs better. That along with vertical centering have been the biggest stumbling blocks. Oh yeah, and I cannot forget padding. When you pad DIVs on Mozilla it will add the padding to the height or width regardless if your content is smaller than the fixed size. IE only adds it to the width and/or height if the content + padding is larger than the fixed size. This is one matter I disagree with the CSS standard, I believe the padding should be applied to the content not the frame. While I am at it, I also think the designers of CSS went the wrong direction by not allowing vertical centering on all tags instead of just table cells!
theJazzyBrain wrote:

Well, since atrributes are moving off the tag and going to style sheets it will finally make many that have abused tables (as I have for years) realize that you might as well move on to other methods of layout and leave tables to the tast for which they were designed.
theJazzyBrain wrote:

Well, it is more than the time involved, you are spending time on people that are not probably going to be a good market for you. If they do not update their browsers which are free, it is doubtful they will purchase any of your services. That is why I consider it truly waste of time.
Same thing happened in the older days when people stayed with Windows 3.1 even after Windows 95 had been out for a couple years. You waste all that time to make your products compatible with Windows 3.1 users but they would not usually buy the software, your purchases usually came from Win 95 or later users.
If they do not feel they need current technology, they usually are not ready to buy anything either.
It depends on what you wish to spend your time and resources. Personally, I would rather spend my time on expanding my services with more features than on people who will probably never be a customer.

I agree with the empty cells, but what is the problem with borders and nesting? I have been nesting tables and I am happy with the result.

I am sorry but I will have to disagree on this. Many books or tutorials that I have read refer to tables as a way to provide layout to your pages. And if they dont they surely not refer to DIVs as a way to provide layout...
and I quote from : http://www.w3.org/TR/html4/struct/tables.html#h-11.1
The HTML table model allows authors to arrange data -- text, preformatted text, images, links, forms, form fields, other tables, etc. -- into rows and columns of cells
in other words, to layout the page.
here : http://www.w3.org/TR/html4/struct/global.html#edef-DIV
The DIV and SPAN elements, in conjunction with the id and class attributes, offer a generic mechanism for adding structure to documents. These elements define content to be inline (SPAN) or block-level (DIV) but impose no other presentational idioms on the content. Thus, authors may use these elements in conjunction with style sheets, the lang attribute, etc., to tailor HTML to their own needs and tastes.
So... I am a bit confused...
LOL...
;P
The bottom line is that I will not stop using TABLES, at least in the near future coz I am happy with them...
It was nice to see other peoples opinions though...
I doesnt really make much difference...

Nested cells have the problem of speed of course. A browser has to make multiple passes if your tables to not specific the exact height and width of all columns and rows. If you have a table nested, it repeats those passes for each level of nesting. I do not know if this happens with DIV's though, and that was kind of the main focus of the question I started with.
There is also formatting problems with nested tables on older browsers. I do not remember exactly what it was, but know I was bit with it many times. Had to do with background colors or images and the background of the page, if I remember correctly.
Borders do not display the same on all browsers. While one may display them as a 3d format others may display them as simple line. The only way around in older browsers is to not use the Table's border but a Style border for the table.

If you are reading books instructing you to use tables to layout a page, then they are the wrong books. Tables are meant for tabular type data. Tables is more of grouping the data rather than its presentation. Many of us never noticed that (me for one, abused tables for years - now trying to clean up my tracks  ) and saw it was handy to arrange content on a page which led us down a path that no longer has to be traveled since we have CSS.
Yes, I can quote from the W3C also:
Tables should not be used purely as a means to layout document content as this may present problems when rendering to non-visual media. Additionally, when used with graphics, these tables may force users to scroll horizontally to view a table designed on a system with a larger display. To minimize these problems, authors should use style sheets to control layout rather than tables
It is not saying that you use the tables to layout your "page" but the tabular data. Your quote says ".. authors to arrange data .." not a page. If you have tabular type data, then a table was designed for that.
theJazzyBrain wrote:

Yes, it would seem so. The DIV tag is without formatting of its own other than being a block type while span is a generic of in-line types. It is the Syle (or Style Sheet Class) that gives it formatting. This allows for greater control on the formatting than to have a tag that restricts your formatting to a specific type. This helps keep your "presentation" code seperate and allows you multiple ways to view the same data without changing its structure. For an example, it might be formatted for a mobile output with one CSS and formatted for your montior with another. Page doesn't change, just the presentation part that is housed in the CSS.
As an extreme example of what you can do with simple DIVs, have you ever seen ZenGarden?
http://www.csszengarden.com/[^]
Quite a site! Just browse the different designs under "Select Desgin". It is hard to imagine the design does not change by the CSS does and it can change so much.
theJazzyBrain wrote:

No one said you had to, if you want to design your sites formatting everything with tables that your prerogative. It is just not the recommended way to layout a site.
The future is still promising for tables, however it is focused more to organizing tabular data along with summaries of the collection contains in tables.

I am developing a premium content web site and need a solution that will prevent resources (HTML and images) from being stolen.
I want to make sure that my valuable research reports and photos can be viewed for only a limited amount of time (that I determine) while disabling common options like "View Source", "Save As", "Print" etc.
Does anyone know of a solution that can effectively shut down content piracy?

None of them really work. They can't, by definition. If you can see it or hear it, you can save it. Welcome to the digital world.
That said, MS has a new offering for exactly what you want. The idea is horrible, in my always humble opinion, but here's the link: http://msdn.microsoft.com/library/en-us/rma/introduction.asp

I am not so sure that MS has what Bud needs.
Bud wants to prevent resources from being stolen.
The MS solution does NOT support Rights-managed HTML that references external script or behaviors which is part of every decent online contnet site ( see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rma/rmh.asp
I suggest that Bud tries a solution called AllRights ( http://www.allrightsdrm.com ) which claims to protect all online resources.
Let me know what you think of the solution

*chuckles* And what exactly would you relationship with AllRights be, Lionel?
The main point of my reply was that DRM doesn't work, period. Not Microsoft's, not AllRights. If you can seen or heard by a human, it can be copied.
All DRM solutions do are make the copying more annoying. In a connected world that doesn't help either, as only one person need copy the original and then that non-DRM digital copy can be passed around freely.
This is not an ethical judgement, it is simply a fact that can't be ignored. I support copyright in principle, but it is impossible to implement technical solutions that enforce copyright of digital works.
Regarding the AllRight product in particular, it's the typical ActiveX control viewer sort of tool. I'm unimpressed. And clearly what it renders can be captured trivially off the screen without giving your ActiveX control a chance to intervene.

There are many ways to have a go at this, such as disabling caching, right-click, etc. Your main problem here, though, is it's not 100% foolproof. Jpeg/HTML etc are not an encrypted format, and as such, the very fact that they must be copied to the client computer means that if the user *really* wants a copy of what's in the browser, they can get it. A savvy user, at absolute worst, can hit the print-screen button to steal your images. Second to that, you're going to have a hard time getting around the fact that you can right-click the system menu icon (top left corner of the browser window) and tell Internet Explorer to save a local copy of the page ("Make Available Offline"). This force-caches the files to the user's temporary internet files folder, where they can then grab a copy of what they want.

I have two web applications, I want that once user login the first application, the user information will be transfered to the second application automatically.
I use session variables to store user information. All that I want are:
1. The second application creates a new session
2. The second application store user information in the session variables
Is it possible to call an ASP page of another application from an ASP page of the current application?
Please help me.

I think that you should be able to call another page as long as you use the full URL...
Dont know how you will deal with security...

I can call another page at client-side but not from server-side. All that I want is calling (or another way) from server-side.
If you know, please show me in details.

I have built an amazingly functional form control for web applications that build their front end using JScript. Basically, it allows you to build a full-featured, completely customisable form with fully configurable validation and error checking. You set up the javascript that is executed when they hit save or cancel, or add your own extra buttons to do what you want when they are pressed. You can have togglable sub-areas that only become visible when a certain field has a certain value in it, for example if a certain checkbox is checked, an extra set of fields becomes visible. The control will generate an xml object containing all of the data in the form and also specify in each node what the data type is (string, date or number). I also have a back end ASP script that you can pass the XML form to and it will automatically update a database table for you if you set up the form correctly. The form code is object-oriented, so you can easily derive your own types of fields to include in a form. I recently created a field object to allow the user to select any Australian suburb.
Take a look at a form I have set up with this control:
http://www.hep10.com/internal/form.gif[^]
If any of you think this would (or wouldn't) be a useful contribution to The Code Project, please let me know before I spend a whole lot of time fixing up the code to be submitted as an article here. I find this extremely useful in rapidly putting together forms in my application as I don't have to write any form validation code, I don't have to create any back end code for processing the form contents, and I can rapidly build large forms with ease. Obviously this would not be useful for someone developing a form the standard way, i.e. with an HTML form tag and a submit button. Although, I suppose you could do some sort of roundabout trick where when they hit "Save" and then form-post the generated xml to the next page? Anyway, your thoughts are welcome.

This one I would question. There would have to be validation on the part of the server to protect it from hacks or plain transmittion errors. You would not want the data to go directly into a database without validation on the server.
On question that comes to mind is how any business logic could be applied if it goes directly to the database?

Hi,
I browse at a internet 'cafe' that keeps things very secure. Here we dont even have the 'command prompt'. We also dont have rights to 'install' new programs.
I was not able to make a ftp connection with my server, that needs user name/password to login.
Is there any way to login to my ftp server through IE itself with the username / password?
Please Help

I was not able to do a PASTE operation. The 'paste' option is still 'not enables' even after i 'copy' a file at my PC.
I had logged in the required user name password....
Drag and drop also didnt help me?!?!

Best to speak to the network admin at the cafe, they may have turned off various explorer functions, such as Paste.
Im sure if your a regular they will install an FTP client and open the relevant ports for you.
