You can always create a property on the select to store the previous value and update it in your onchange handler. EX:
<script language=javascript><br />
<br />
function OnSelectChange() {<br />
var oElem = window.event.srcElement;<br />
var cOrigValue = oElem.LastValue;<br />
var cCurrValue = oElem.value;<br />
<br />
.. do whatever here...<br />
<br />
oElem.LastValue = cCurrValue;<br />
}<br />
<br />
</script><br />
<br />
<select name="MyDropdown" LastValue="" onchange="OnSelectChange()"><br />
<option value="red">Red</option><br />
<option value="white">White</option><br />
<option value="blue">Blue</option><br />
</select>
onwards and upwards...

Not sure about Netscape. We stopped developing for Netscape about 4 years ago. It is a HORRIBLE platform to develop real, functional business apps for.

What version of Netscape?
A good list of many known bugs in the CSS implementations of different browsers can be found here:

Unfortunately, it only covers up to IE5.5 and NS6.

We are going to be moving from one live web server, to 3 forming a web farm in the next month or so. We'll be using SQL and cookies to track sessions, and so far the examples I've looked at look great. However, one thing I'm not too sure of it the Verisign certificates. Obviously I have contacted them for more info, and it's looking very interesting, but I was wondering if anyone has experience of this, and if so, what advice (do's / don'ts  ) you give?
Thanks

I would, if you can ! get your own certificate server (Netscape).
You can request your certs from the MMC within IIS (if you are using IIS) and go to town
The cipher strength can be whatever 40bit, 128bit etc.
This will insure the protection of the packets being routed and the whole nine yards.
My employer considred VeriSign but decided it was too much of a hassle, not to mention the overhead.

Do you know of a good on-line tutorial on this subject. I have been planning on a SSL gatway on my web server but it is all new to me, have not done anything with SSL/HTTPS before.

Hi,
I was just wondering - have you set one of your machines up to be a certificate server then? I know this is possible using Win 2000, but then who is backing you up as it were, to prove you are who you say you are?
Thanks

M,
Is this related to the topic?
Are we talking about authentication?
Please clarify.
Thanks

Hi Tony,
When you have a certificate from Verisign you aren't only using SSL, but there's the added benefit with people being able to see that a reputable organisation like Verisign say you are who you say you are. We don't want to lose this as we have brokers trading through our site.
If we issue our own certificates, who is backing us up? We could be rogues, pretending to be Virtual Net (Europe) plc, stealing the money. I was wondering if you've found a way of getting around this.

M,
I see what you mean!! That is a good reason to have an org like Verisign !!!
Liability would be a strong contender in your setup.
Our setup has a differernt purpose. I do know that it would take a hacker many moons to Decrypt a 128bit encryption algorithm, but when you deal with peoples finances it's one that requires vigilance--ongoing.
I don't have a workaround, however, I was thinking that if you use your own SSL certs they are less likley to be exposed to any other third party. Not to say that Verisign would be vulnerable to compromise, but hence the saying "too many cooks in the kitchen" anythings possible.
Your post has prompted me to look further into this by all means. If I find something out I will pass it on.
Thanks M

Lets say I have to frames in a frame page. In panel (A) I have links:
Link 1
Link 2
Link 3
All of which target panel (B). In panel (B) I have some text and link to "Link 2". A user then clicks in panel (B) on "Link 2" which replaces Panel (B) with the contents of "Link 2". How about I go about refreshing Panel (A) so that the link shows as someone has already visited it without refreshing the entire panel?
That is the Visitied link color does not automatically show until the page is refreshed. Is there something that can refresh the page without fetching the page again so that the link changes color?
Oh yeah, and lets say that in Panel (B) I do not know if the link exists on Panel (A) so I can not adjust he color of the link manually.

I want to show a very wide image on a page but not have it cause a horizontal scrollbar to appear.
I found the overflow-x attribute[^] but it only works on IE6. Is there a portable way of doing this (without using frames )?

Could you set the image as the background image for the page or a div?

What I need is to reload the page with parameters depending on users selection.
First from application main window i open new dialog (using javascript):
showModalDialog(DIALOG_NAME, DlgParameters, DlgAtributes);
(dialog name, parameters and atributes are predefined or generated variables).
Till here everything works fine, but when I try to reload the page it automaticaly opens new browser window.
<a href="SelectData.aspx?d=125&m=15">DATA 15</a><br />
<a href="SelectData.aspx?d=151&m=16">DATA 16</a>
Same happens when I try it with javascript i.e:
<a href="javascript:ReloadWindow('SelectData.aspx?d=125&m=15')">DATA 15</a>
function ReloadWindow(DestinationURL)<br />
{<br />
document.location = DestinationURL;<br />
}
Everything works fine when I use browser window instead of ModalDialog window.
So is it posible to reload the page inside the ModalDialog window?
If yes, how?

<html>
<head>
<title>Multi Select Lookup</title>
<SCRIPT LANGUAGE=javascript>
<!--
var g_iInterval = 0;
var g_iLoop = 0;
function window_onload()
{
document.all["LookupPanel"].style.display = "";
document.all["LoadingMsg"].style.display = "none";
window_onresize();
window.returnValue = "";
g_iInterval = window.setInterval("CheckForSave()",200);
}
function CheckForSave() {
if (window.returnValue.substr(0,1) == "R")
{
g_iLoop++;
if (g_iLoop > 2)
{
window.clearInterval(g_iInterval);
window.close();
}
}
}
function window_onresize() {
var oLP = document.all["LookupPanel"];
oLP.style.posHeight = document.body.offsetHeight;
oLP.style.posWidth = document.body.offsetWidth;
}
</SCRIPT>
</HEAD>
<BODY background="::{ImageDir}/body_back.gif" bottomMargin=0 leftMargin=0 rightMargin=0 topMargin=0 LANGUAGE=javascript onload="return window_onload()" onresize="return window_onresize()">
<span id=Retval style="display: none"></span>
<SPAN id=LoadingMsg style="z-index: 0; position: absolute; left: 0; top: 100; width: 100%; text-align: center">Loading...</SPAN>
<IFRAME id=LookupPanel src="!!YOUR URL HERE!!" marginheight=0 marginwidth=0 hspace=0 frameborder=1 style="HEIGHT: 10px; WIDTH: 10px; Z-INDEX=10; DISPLAY: none" vspace=0></IFRAME>
Then, in your page, when you need to close it (or doing a form post), simply set the following:
function OnCancelButtonClicked() {
window.parent.close();
}
function FormOnSubmit() {
window.parent.returnValue = "R";
}
Using this as a foundation, we were able to develop true multipage Wizard dialogs and Tabbed dialogs.

Well done my friend...
Very good... Why dont you write an rticle about this?...
I am developing a web app which requires alot of wizards etc...

Thanx alot...

Who has time to write articles....and how interested are people here about HTML... seems to be a C++ dominated board. If you are interested, I could share with you some "wizard" templates and "tabbed dialog" templates.
onwards and upwards...

|

|

that would be great...
Although I haven't got anything to give you as I am still on design ...
implementation will start in 2,5 weeks...
but I am open to anything you can share...
And there are people who are developing heavy web apps, like me! and these tips are very helpful...
By the way, have you ever used the Web Service Behavior?

Just some background: In addition to electronic mail campaign software, we have a group that develops a C++ targeted web application server. In addition, there are numerous client libraries that ship with the product. Items such as calculators, calendars, form validation, drilldown trees, wizard dialogs, tabbed dialogs, etc. What we try to do is provide the framework for developing the fastest, most scalable web apps possible, while providing the same functionality that you would get with a regular client app. So, many of these libraries have been developed over the last couple years.
But, I'd be glad to help you out.
