Put following code in to your page load..
Response.Buffer = True
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1D)
Response.Expires = -1500
Response.CacheControl = "no-cache"

I work in a web development team of 2 people.
I always just use document.getElementById('blah')
My co-worker always uses a "getLayerObj" function and includes a reference to a 24KB javascript file (dynlib.js) just to use this.
<br />
<br />
function getLayerObj(LAYERID) {<br />
if (ie4) return document.all[LAYERID];<br />
else if (ns4) {<br />
var tempLayerObj = null;<br />
var tempParentObj = (arguments.length == 1) ? document : arguments[1];<br />
for (var tempLayerLoop in tempParentObj.layers) {<br />
var tempObj = tempParentObj.layers[tempLayerLoop];<br />
var tempConstructor = tempObj.constructor + '';<br />
if (tempConstructor.indexOf('function Layer()') != -1) {<br />
if (tempLayerLoop == LAYERID) return tempObj;<br />
else if (tempObj.document.layers.length > 0) tempLayerObj = getLayerObj(LAYERID,tempObj);<br />
}<br />
}<br />
return tempLayerObj;<br />
}<br />
else if (dyn) return document.getElementById(LAYERID);<br />
}<br />
My opinion is this is unnecessary.
I'm trying to get a feeling for whether mine is a minority or majority view so I'd be grateful hearing what everyone elses practice is?
Cheers.

I'm with you: getElementById is recognised by all modern browsers on both PC and Mac, and IMHO if anyone wants to use something else that's their lookout; It's hard enough (well, ok, time-consuming enough) to code HTML, CSS and Javascript to cope with the major browsers and platforms without having to pander to *every* alternative out there. Somewhere down the line, users have to take responsiblity by using compliant browsers.
Compliant browsers? Someone's going to say "That rules out IE then!" No it doesn't... I'd like someone to tell me by what right w3c and their affiliates determine standards? I don't remember voting for them any more than Microsoft... in fact, I *did* vote for Microsoft:- with my wallet by buying their products.

If you check the W3C member list[^], you will see the Microsoft Corporation is one of them.

Well of course they would be. That's politics for you. Point is though, Microsoft are the big boys, the winners if you will, and the winners always write the history...and set the standards. What's the point in winning otherwise? Why strive to run faster than everyone else if someone else is going to come along and say you're not allowed to run faster than your competitors?

The line it is drawn
The curse it is cast
The slow one now
Will later be fast
As the present now
Will later be past
The order is
Rapidly fadin'.
And the first one now
Will later be last
For the times they are a-changin'.

But as they are members, that makes your point pointless. Microsoft is part of the group that has set the standards, and that group is W3C. By being a member, Microsoft has acknowledged W3C as being the group that sets the standards.

Very, very, very few people still use Netscape 4, even fewer IE4. If you're aiming at the general population, your time would be better spent making sure Opera and Safari or even the last Mac IE render properly. Unless you are stuck supporting in-house users that are all deeply in love with it, i'd drop IE4/NS4 support faster than a hot chunk of iron.
Heck, even if you do have NS4 users in-house, your time would probably be better spent upgrading them to FF or IE7. This is hardly the only work-around you'd need to properly support such older browsers.

It appears that everybody is under the impression that I approve of the documentation. You probably also blame Ken Burns for supporting slavery.

Thanks for the responses so far.
We're not trying to support IE4 and NS4 explicitly, we don't test our sites in them and I know for a start the code I've written won't work in them as well as very likely things like our tree view and menu controls and pages that use AJAX!
Related to Shog's point actually and going off on a bit of a tangent does anyone know where I can get reliable browser usage stats for the web as a whole?
I know the w3c stats page but it's not a representative sample.
Do any of the mega sites (e.g. Google, Yahoo, Microsoft) make their stats available anywhere?

Short answer: you can't.
Longer answer: the reliability of any statistics based on user agent strings is somewhat poor; while well-behaved spiders will identify themselves as such, there are plenty of spam bots and site scrapers that will identify themselves as browsers to avoid detection. And even if this wasn't true, unless you're setting up the next Google or Y!, Google and Y! stats aren't even applicable - you might have a very different set of users, and browsers that are a tiny minority among visitors to those sites could be a sizable percentage of visitors to yours - or completely non-existent.
The best suggestion i can give you (if your site is already live) is to analyze your own logs or use a service such as Google Analytics[^] to collect information on who is visiting with what browser. And then, take it with a grain of salt.

Hello All,
I want to make a website that will contain a number of galleries each gallery will have some photos and each gallery will be in a separate folder with different name, the problem is that I don't know if I can pass the folder name dynamically to the flash to load images within this gallery, or something like that. The main idea is that everything will be dynamically (i.e. I don't know # of galleries or their names, # of photos or their names ...) any ideas? (note: tools that allowed to be used, asp.net, flash, swish, xml, sql)
Thanks

Error: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.

You mean that this is part of your code? It's not enough of your code to diagnose the problem.
How do you create the image object? Why do you create a memory stream that you don't use? Why are you changing the content type of the page when you are still creating an html page?

Wow. I'm guessing that you just cobbled together this code without actually trying to figure out what it does?
The error probably indicates that you're trying to save to an invalid path, or to a location where the ASP.NET user doesn't have write access. But that's hardly the only thing keeping this code from working.
- Stop.
- Think about what you're trying to do.
- Identify what needs to happen in order to accomplish that.
- Write the code to do those things.
- If you are tempted at any point to include even a single line whose purpose you do not know or understand, stop and re-think what you're doing.

Does anybody know if it's possible to configure IIS to allow write access to a folder and all it's sub folders to ASP.NET??
/\ |_ E X E GG

I am not sure if you are asking it you can do it through programming in C#. If you are, then the answer is no. If you are talking about manually, then yes you can. You have to look at what the identity of your app pool is running as. Be default it is aspnet. So you can give aspnet and iis_WPG access to the folder and subfolders. You should make sure to give mimimum access that is needed, since in general you really don't want to give IIS rights that it doesn't need. Just make sure that whatever rights you give to the aspnet user you all give to iis_wpg group.
Hope that helps.

IIS does not control disk access.
Open the properties for the folder and go to the security tab to change file access for users. The account that is used for running ASP.NET code is usually ASPNET or IIS_WPG.

As long as you are only concerned abnout doing this on your own, private development machine, I have found the simplest way to deal with this "problem" is to add a line like the following to the web.config file of the application:
<identity impersonate="true" userName="XXX" password="YYY" />
where XXX/YYY is a(n) administrator login for your machine. Make sure you don't upload this to the deployment server... I only resorted to this because for reasons I never could fathom I had a hell of a job trying to configure the ASPNET account to have write access. But this works.
cheers
