I am interested in reading a database with ASP.net and then feeding the results into javascript. Is it possible to do this directy... How can i pass the results of an ASP function to a javascript function?
Thanks...

What is it your attempting to accomplish? Look at the RegisterArrayDeclaration function, this might give you are starting point.

You can't. ASP is processed on the server, javascript is processed on the server. You would need to write the return value into the javascript before it gets rendered to the page.
string strBar = "function MyJavaFoo(" + MyFoo() + ")";
RegisterClientScriptBlock(strBar);
You get to figure out what is missing from above code.

One important thing to remember in web development is that all you ever send back to the client from the server is text. Nothing more. The server does not care whether that text represents HTML, CSS, JavaScript or a soft pron film script.
How this helps you is that you do not have to do anything different when you want to send back JavaScript as opposed to HTML.
So you can have the following in your ASP:
...
<script language="javascript">
<%
For X = 0 to 100
Response.Write "var i" & X & " = " & (X * 100) & ";"
Next
%>
</script>
...
That will then send text back to the client which the browser will interpret as being a block of JavaScript which has 101 variables (named i1, i2, i3, etc.) and being assigned a value.
This technique once realised is quite powerful.

Hi CPians,
My IIS won't start and I get "HTTP 500 - Internal server error" always.
I got IIS 5.1 installed on Windows XP Pro with SP1.
Even http://localhost gives the same error. When I turned off the "Friendly error messages" option in IE, I get "Server Error - Bad URL"
I logged into my computer as an admin.
Default Web Site -> Properties -> Directory Security (tab) -> Edit (Anonymous Access and Authentication Control) -> cleared the checkbox (Anonymous Access)
Could you guys give me some points where to start to fix this problem?
BTW, I got Visual Studio .NET installed with C#.NET and installed ASP.NET (via aspnet_regiis.exe)
thanks

I'm trying to enumerate all <embed> tags in a page by using IHTMLDocument3::getElementsByTagName() and IHTMLElement::getElementsByTagName() (calling that on the <body> element), but both are returning an empty list. Is getElementsByTagName() just plain b0rked or is "embed" handled specially?
This is on IE6 if it matters.

No luck, embeds also returns an empty list.  Any other ideas?

Don't use the IHTMLDocument3 interface, it doesn't support the embeds collection, unlike IHTMLDocument2. (IHTMLDocument3 doesn't override IHTMLDocument2, but IDispatch instead).
This code works fine for me :
CComQIPtr<IHTMLDocument2> pHtmlDoc( GetHtmlDocument() );
if (!pHtmlDoc) return;
CComPtr<IHTMLElementCollection> p = NULL;
pHtmlDoc->get_embeds(&p);
long nb = 0;
p->get_length(&nb);
|

I am calling it through a IHTMLDocument2 pointer (otherwise, like you said, it wouldn't compile). *shrug* I'm doing:
MSHTML::IHTMLElementCollectionPtr pEmbedColl;
long l, lLen;
pEmbedColl = pDoc->embeds;
lLen = pEmbedColl->length; lLen is 0 no matter what.

This code is alright.
Make sure you access the DOM when it's ready for use. For instance, my code is executed in the OnDocumentComplete() event handler.

How to add the icon to be displayed in the web-browser's address bar. CP, Google etc does it......
|
|
|
|
|
1 - Create the icon that you want to use
2 - Name it 'favicon.ico'.
3 - Place it in the root of your website
That should be all you need to do.

Ray said it all. No meta data, no modification to your files, no IIS settings, no CSS, no JavaScript, no nothing. Just make the favicon.ico, put it in the root and hey presto.
On word of warning though: Favourite Icons may disapear after awhile as they are stored in the temporary internet files folder. IE unfortuantley does not re-download the file.

Okay C# scripting? can it completetly replace javascript?
Could somebody help me out and tell me how i can do this in C#:
document.getElementById("table1").style.color = 'red';
and also how can i call multiple functions on an event?
ie.... onMouseover="Foo1();Foo2()" like this in java

No, C# is server side only (for the time being).
The rest of your answer would be. NO. No. No. No.  It would also be better to ask C# related questions in the ASP.NET forum.
Anything client side needs to be javascript (those questions again are valid in this forum).

Just like that. Although it may be better to write one function to wrap it all. Less hassle to change multiple lines rather than just one function.
function AllFoo()
{
Foo1();
Foo2();
}
onmouseover="AllFoo()"

There is a keyword in Javascript and C++ - this, that points to current instance of class, function, etc. So my question - is there any such keyword, property or whatever like "this" in VBScript?
For example I have a Class and it creates another one, to which I need to pass its parent (this), how to do it in VBScript?

Yes: me is the same as this in VBScript. Same for normal VB.
Understanding Events has an explanation and some examples.
