Re: How to call instiantiate a class that has only initialization code

I don't understand what you are trying to accomplish. How does the variable BRAND get set to a value? How does anything access the URL that is set?

HI,

The variable BRAND and URL are global variables and BRAND is assigned a value (O or G) out side this class. All i am trying to do inside the class is depending upon the BRAND value, i am trying to set value for the variable URL. I have only constructor and do not have any function or procedure. I tried instiantiate the class so that this constructor will be called, and was getting error during class instiantiation.

Hope i am clear in explaining my requirements.

Thanks,
Karthikeyan A

What language are you using? And why are you accessing global variables inside of a class? The values should be passed from the class using let/get propereties.

See Code below.

<%@ LANGUAGE = "VBScript" %>

<% 

class Init

	private m_url 

	'--You can access these by var.Url 
	'--You could also do validation before you set the variables
	public property get Url()
		Url = m_url
	end property

	public property let Url(RHS)
		m_url = RHS
	end property
	
	private sub Class_Initialize() 
	end sub  
  
	private sub Class_Terminate() 
	end sub  
  
	public function DetermineUrl(sBrand)
		If sBrand = "O" Then
			m_url = "http://ooo.com"
		ElseIf sBrand = "C" Then
			m_url = "http://ccc.com"
		End If

		DetermineUrl = m_url
	end function


end class  

dim test 
Set test = New Init

'--Returns variable 
Response.Write test.DetermineUrl("O")

'--Variable keeps its value so now there is no need for global variable 
Response.write (test.Url)


test.Url = "http://ccc.com"
Response.write (test.Url)

Handling <img> tag

jaymacher13-Jun-06 1:08

13-Jun-06 1:08

Actually I was looking into how exactly the tag would be handled...
I am currently trying to implement how exactly the image would be downloaded on coming across an IMG tag in a HTML..
Basic idea was to gradually build a browser .. so i was catching up on features of browser like hyperlink,Image rendering....
I would like to know how the images are queued up for downloading ...
What are the series of events that occur when we come across the IMG tag in a HTML...
I guess if we go by the generic architecture we have something called the Download Manager...
Can someone shed some light on the design and coding aspects

You can implement some sort of alphabetical filter in conjunction with some AJAX trick.

php form email issue

I'm trying to send some form variable to my email address, however it doesn't work and I can't seem to figure out why.

Any help would be appreciated. Thanks!

<?php
if ($_POST) {
$FirstName = $_POST['firstname'];
$LastName = $_POST['lastname'];
$PhoneNumber = $_POST['phonenumber'];
$Email = $_POST['email'];
$City = $_POST['city'];
$State = $_POST['state'];
$Zip = $_POST['zip'];
$QuestComment = $_POST['questcomment'];
$to = "myemail@mysite.com";
$subject = "Question/Comment website user";
$message =
'First Name:'.$FirstName . "\r\n" .
'Last Name:'.$Last Name . "\r\n" .
'Phone Number:'.$PhoneNumber . "\r\n" .
'Email Address:'.$Email . "\r\n" .

Hi,

Try replacing: if ($_POST) {

With: if ($_SERVER['REQUEST_METHOD']=="POST") {

If I remember right $_POST, along with $_GET, $_REQUEST, $_SESSION and $_COOKIE, are always set no matter what HTTP method is used to call the script.

Graham.

a javascipt qustion

Hi everybody,I'm a new comer to javascript.I have a question.English is not my mother language.I'll try my best to explain clearly what I mean.
Look at the following code:

<br />
<script type="text/javascript" language="javascript"><br />
<br />
var CallComplete;<br />
function MyFunction()<br />
{<br />
  CallComplete = false;<br />
<br />
  //Make asynchronous call of a server method<br />
  SeverMethod(CallBack);<br />
<br />
  //wating for CallComplete<br />
  //but it takes such a long time to waiting the call complete<br />
  while (!CallComplete)<br />
  {<br />
  }<br />
  return something;<br />
}<br />
<br />
function CallBack(response)<br />
{<br />
  ...<br />
  CallComplete = true;<br />
}<br />
<br />
</script><br />

The ServerMethod is quite simple,and it will return immediately if I remove the while loop from the above code.But MyFuntion must wait for the severmethod's data to return values.
Is there any better way waiting for the asynchronous call complete? Any idea will be appropriate.

The reason for having a callback is that you don't need to wait for the call to complete. When it completes the callback method is executed. Whatever you need to do after the call completes, you can put in the callback method.

But disabling a textbox would prevent it from getting submitted. You may consider having a readOnly attribute and then a style of disabled to apply instead.

CSS link problems

JackIsMe77712-Jun-06 12:55

JackIsMe777

12-Jun-06 12:55

I have three different styles of links that I would like to have on page...

1. General links on the page
2. Navigation menu links
3. Page footer

The problem I'm having is that the different styles keep on affecting other ones randomly. For example, the general links on the page are supposed to be in (Verdana, Helvetica, Arial, sans-serif), however they are inheriting (monospace) from the footer?!?

I have the navigation menu setup in a div like this:
****************************************************
<div id="navmenu">
<a href="#">Menu Link 1</a>
<a href="#">Menu Link 2</a>
</div>
****************************************************

...and the footer setup liks this:
****************************************************
<div id="footer">
click <a href="#"> here </a>
****************************************************

Here is my CSS code:
****************************************************
/*NAVIGATION MENU LINK PROPERTIES*/
#navmenu a, a:link, a:visited, a:active {
padding-left: 25px;
padding-top: 5px;
padding-bottom: 5px;
font-variant: small-caps;
line-height: 30px;
letter-spacing: +1px;
font-family: cursive;
font-size: 12px;}

/*NAVIGATION HOVER PROPERTIES*/
#navmenu a:hover {
color: #eded0a;}

/*GENERAL LINK PROPERTIES*/
a, a:link, a:visited, a:active {
padding: 0px;
margin: 0px;
color: #f8f8f8;
font-family: Verdana, Helvetica, Arial, sans-serif;
font-size: 11px;
font-weight: normal;
font-style: normal;
text-decoration: none;
text-indent: 0px;
text-align: left;
font-variant: normal;
text-transform: none;}

a:hover {
padding: 0px;
margin: 0px;
color: #f8f8f8;
font-family: Verdana, Helvetica, Arial, sans-serif;
font-size: 11px;
font-weight: normal;
font-style: normal;
text-decoration: underline;
text-indent: 0px;
text-align: left;
font-variant: normal;
text-transform: none;}

#footer a, a:link, a:visited, a:active {
font-family: monospace;
font-variant: normal;
padding: 0px;
font-size: 10px;}
****************************************************

Thanks for any help you can give!

That is because you have specified the id for the a and a:hover elements only, the a:link, a:visited and a:active also need the id:

#navmenu a, #navmenu a:link, #navmenu a:visited, #navmenu a:active {<br />
<br />
#footer a, #footer a:link, #footer a:visited, #footer a:active {
