document.all["something"].SetAttribute("HREF", "stylesheet.css",0) does not work

Hi, 

I am doing a practice exercise of the book "Developing Web
Applications with Microsoft Visual Basic.Net." There is also a little
javascript involved. There is a practice which is all written out in
the book, so I 'just' have to type it in. Well, it isn't that simple.

Here is my code:

<%@ Page Language="vb" AutoEventWireup="false"
Codebehind="WebForm1.aspx.vb" Inherits="StyleSheetTest.WebForm1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
	<HEAD>
		<title>WebForm1</title>
		<meta name="GENERATOR" content="Microsoft Visual
Studio .NET 7.1">
		<meta name="CODE_LANGUAGE" content="Visual Basic .NET
7.1">
		<meta name="vs_defaultClientScript"
content="JavaScript">
		<meta name="vs_targetSchema"
content="http://schemas.microsoft.com/intellisense/ie5">
	    <link id="ScreenStyle" type="text/css" href="Styles.css"
rel="stylesheet" media="screen">
		<link id="PrintStyle" type="text/css"
href="BigStyle.css" rel="stylesheet" media="print">

		<script id="ClientEventHandlerJS" language="jscript">
		function SwitchSheets()
		{
		if (document.all["ScreenStyle"].getAttribute("HREF")
== "Styles.css")
		    //alert("Yes")
 document.all["ScreenStyle"].SetAttribute("HREF", "BigStyle.css",0);
		else
 document.all["ScreenStyle"].SetAttribute("HREF", "Styles.css",0);
		}
		</script>

	</HEAD>
	<body>
		<form id="Form1" method="post" runat="server">
		Test1<br>
		Test2<br>
    	<br>
		<br>
		<a onclick="SwitchSheets()" href="#">Click here</a> to
change the stylesheets.				
		
		</form>
	</body>
</HTML>



There are 2 stylesheets, StyleSheet.css and BigStyle.css. One is
copied from the other. Only the font-size is changed, so there
couldn't be anything wrong with the copy.

When the user clicks on 'Click here', the function SwitchSheets should
switch the stylesheets:
document.all["ScreenStyle"].SetAttribute("HREF", "BigStyle.css",0);

The only thing I get is 'error on page'.

I have IE 6. What am I doing wrong here?

Why does the method of modules use a dot, and the constants a double colon? e.g. Math::PI and Math.cos -- Posted via http://www.ruby-forum.com/.

"out" and "in out"
Hi i found the following explaination: In Ada, "in" parameters are similar to C++ const parameters. They are effectively read-only within the scope of the called subprogram. Ada "in out" parameters have a reliable initial value (that passed in from the calling subprogram) and may be modified within the scope of the called procedure. Ada "out" parameters have no reliable initial value, but are expected to be assigned a value within the called procedure. What does "have no reliable initial value" mean when considering the "out" parameter? By c...

"/a" is not "/a" ?

"my" and "our"
Hi, while testing a program, I erroneously declared the same variable twice within a block, the first time with "my", the second time with "our": { my $fz = 'VTX_Link'; .... ( around 200 lines of code, all in the same block) our $fz = 'VTX_Linkset'; ... } So the initial contents of the $fz declared with "my" is lost, because "our" creates a lexical alias for the global $fz, thus overwriting the previous "my" declaration. It was my error, no question. But I wonder why Perl doesn't mention this - even with "use s...

Re: "out" and "in out"
"no reliable initial value" means, you cannot rely on the value, but it may have a value. This depends on the parameter passing mechanism, which is _not_ related to the parameter mode (contrary to what many people think). So the parameter mode is there (nearly) solely for the information of the reader. The parameter passing mechanism for all kinds of parameters is defined in the RM. There are parameters passed by copy (in and out), by reference; for some it is explicitly left undefined. In your case, the passing mechanism is by reference, so you get what you get. But don't rely...

why have both "." and "->" ?
