I've been having a look at this example of doing http requests from the client side in IE / Firefox :
webpasties.com/xmlHttpRequest/ and it looks awesome.
However, I can't find any realworld examples of what you can do with the resultant xml.
Does anyone have examples of looping through an relatively simple XML file?
Cheers,
Simon

I develop a page that get html content from an URL. For ex, from Yahoo search engine, I want to get the search result by request to the URL:
http://search.yahoo.com/search?p=codeproject&sm=Yahoo%21+Search&fr=FP-tab-web-t&toggle=1
But using frame is not allow here. 
Before, I build an ASP page that using ASPTear.dll to get the html content then response.write to the client browser. And my server is overloaded 
Now, I want the client browser request to that url and get the html content, not myserver. That's mean, the request come from client browser (by client-side scripting).
Help me please.
Thanks all of you.

Hi everyone,
Does anyone know of any good articles about the best arcitecture to set up a simple 3-tier (UI, Biz, Data Access) for an asp.net web application. And most importantly - the communication between the tiers.
I've been talking to myself for a few days now, and I still can't decide the best approach.
For example - what if something goes wrong when trying to retreive data from a DB, I don't want to rely on exceptions as it slows down execution. In the past I've created a class that holds the information from the query to the DB, which has an error object, which will tell you if the operation was succesfull.
However, it wasn't a very 'clean' approach.
Anyone got any 'clean arcitecture' articles??!
Cheers
Dan F.

In general the communication can be summarised as follows. The upper teir (UI on top, then Business, then Data on the bottom) can call into the teir below. If the lower teir below needs to communicate upwards then use events so that the coupling between layers is reduced. i.e. the lower teir exposes a number of events which it fires and the upper teir subscribes to those events. For a good example look at the way events are used in the UI layer so that Microsoft don't need to know anything about your code in order for their UI code to invoke your methods.

What is an exception for? It is for when something exceptional happens. If you expect that the database isn't going to be there then you should test for that in advance. If a missing database is really a very rare and totally exceptional thing to happen then you should use exceptions. Don't use the tired argument that exceptions are slow to avoid them. Yes, exceptions are slow - but then the circumstances in which they are thrown are exceptional and should not happen often. If your code is throwning many exceptions a second then I would say that your code is wrong. If it throws an exception only occasionally then it sounds as if it is going great (assuming that you are catching and handling the exception).

And how did the database communicate a failure? Most likely it threw an exception. In which case just let up bubble up to where it can be handled most efficiently.

I have a problem with sizing tables on a web page. I need to make the table height = 100% so that the bottom row always appears on the bottom edge of the page. However, if I use the attribute is ignored.
If I use it renders correctly both in IE and firefox. But according to the w3.org validator this is not valid HTML (there is no attribute "HEIGHT").

Ah, finally figured it out. The problem in with standards complient mode the page doesn't fill 100% of the window, so you need to do this in the style sheet:
body {
height:100%;
}
html{
height:100%;
}

I would have to see your code to figure out how to do what you want, but it doesn't sound like a huge problem. You can post the code here (in this thread) or email to me if you like.

I have been asked to make a webpage (that is running fine on IE and Mozilla) to run on Safari. Is it a problem with the code? what should I change or add on my code to make the webpage run on any browser?
the page runs fine on various browsers such as IE or Mozilla but not on Safari. What is the problem and how can I solve it?
Please any help would be appreciated.
Thanks
McBel

The problem is that Safari is crapola. The issue will be with it treating specific HTML tags differently. Do a google for what tags are treated differently by Safari, then find where you use them, and either change to something else, or detect Safari and have a seperate Safari rendering layer.
Yuck, yuck, yuck.

i don't know how to draw a curve with axis in javascript?
help me.
thanx

I'm not sure what you mean by "draw a curve with axis", but it sounds like you want to do some graphing/charting/plotting on a web page.
If you need to do this only in Internet Explorer, VML (vector markup language) might be the simplest way to implement graphing. There are also some obscure javascript methods by various web developers that might do the job (though I don't recall at the moment where I saw them--and Googling on this subject brings up too many links).
Could you describe your need in more detail?

Ganesh:
I would be glad to help, with the understanding that I am by no means expert in either Javascript or vml. However, I have implemented several scientific graphic projects using vml and may be able to point you in the right direction.
To get a basic understanding of vml, check out the following links:
http://msdn.microsoft.com/workshop/author/vml/default.asp
http://www.w3.org/TR/NOTE-VML
http://www.steema.com/downloads/dwn_tch_office.html
About 1998 (I think) Microsoft and others submitted vml to the W3 crowd in an attempt to obtain recognition of their markup language as a web standard. However, Adobe and others also submitted a similar language to W3 at about the same time. W3 accepted neither, instead deciding to merge ideas from both and come up with yet another graphics language, SVG or scaleable vector graphics. SVG is now a web standard.
Microsoft's motive was this: they already had planned to bring out vml anyway as a means of exporting web graphics in Office 2000. If you check out one of the programs in the Office suite, say Excel, you will see the vml code when you export to html. The Microsoft output is, however, a mess: too verb verbose and opaque for understanding vml coding. You will obtain much simpler code from using Tchart Office (third link above, Steema software). This program is a free download.
Try out the Tchart program, adjusting the chart dimensions and other parameters with data you may already have. Export the graph to VML and examine the resulting code. This may be sufficient to get you started, if you already know html and javascript, and have read a bit from the first two links above.
If not, let me know. I am willing to post some code that may help you implement your project.
