Hello. Here's my problem:
Let's say I have a computer where I can play mp3 files using a player...winamp or whatever ->this will be my server. I would like to know how I can make a web page where all the users that connect can hear what I am playing and if I change the song here, it should change it at their home also. Any ideas?
Thanks in advance!

Hey all
I have a textbox with a max length of 5
the first three chars must be uppercase letters between [A-Z]
the final two chars must be between [0-9]
I am trying to do this as a regex function in the onChange Event using Javascript, but my Regular Expressions aren't very good.
currently I split the textbox.text into two string variables
str1 = orgID.substr(0,3);
str2 = orgID.substr(4,5);
Then I run a (very) simple regex expression on each of these substrings.
How would I do this formatting without breaking orgID into 2 substrings?
Thanks for help
Jason

You can use direct access to chars:
str.charAt(index);

I am not sure what you exactly want, but if you only want to test the format of the string you can use:
<br />
var re = /[A-Z]{3}\d{2}/;<br />
<br />
if(re.test(orgID))<br />
{<br />
...<br />
}<br />

Hi all,
I am getting this quite an unusual error in my JavaScript script.
What i am trying to do is to increase the height of a DIV named as f4 as follows:
var z = f4.style.height + 22;
f4.style.height = z;
As soon as the second line is executed, i get an error in the browser which says "Invalid Argument" and the height remains unchanged.
Initially i thought that this was happening because i did not mention any height attribute. But it is occuring even after providing the same.
I am really confused.
Any help will be highly appreciated.
Thanks in advance.

The height attribute is a string value, that may contain something like "100px". If you add the value 22 to the string, the value will be converted to a string, and the result will be "100px22". This is of course an invalid value.
Keep the height you want in a variable, and use that variable to produce a value for the style by adding "px" to it (or any unit you like).

Hey Guffa,
You are great man...
I dont know how you always come to my rescue, be it C# or JScript.
That solution indeed solved my problem.
Can you please help me out in one more thing.
Well, i continued making my script and found one strange thing.
I have some DIVs, and their heights are being set by a CSS class. Now if you try to retrieve the height of any of the DIVs, the value returned is blank. I mean nothing is returned. Say, i tried:
alert(f4.style.height);
and this returned a blank alert.
Just before this statement, i added a:
f4.style.height = 22px;
then when i tested, the alert showed the height as 22px.
Is this behaviour normal, or am i going wrong somewhere ?
Please help.
Thanks in advance.

It's normal. The style that is set using a CSS class is not stored in the style property.
You can use the currentStyle property to get the actual style that is the composite of default styles, css styles and inline styles. It's not part of the standard DOM, though.

Hello,
I read about the automatic update Microsoft was to install on April 11th but decided to delay. I understand ActiveX, Flash, and Java applets will be affected by this in that you have to manually activate them before they are usable.
Does the same apply to .NET controls being embedded in a web page? How will those be affected, if at all?
Thanks,
Hashir

Hi,
Is the javascript code used to create an IFrame correct?
The script is typed in a seperate javascript file and asp.net(vb) code will call the javascript method.
The script below is supposed to display an IFrame on the webpage when the webpage loads.
function showIFrame()
{
var iframe = document.createElement("iframe");
iframe.id = "testiframe";
iframe.name = "testiframe";
iframe.frameborder = 1;
iframe.style.top = 100;
iframe.style.left = 100;
iframe.height = 185;
iframe.width = 175;
iframe.style.position = "absolute";
iframe.style.display = "block";
iframe.scrolling = "auto";
iframe.src = "C:\Test.html"
window.document.body.appendChild(iframe);
return false;
}
However, there is no IFrame displayed when the page loads.
Is there anything wrong with the jscript above?

But before request is send to server I want to valid the data entered in the text boxes when User clicks submit button.
How can I do that?

All~
I know this is a longshot but...
Here is what I have:
- Our App which captures info out of another 3rd party app.
Here is what we are looking to do:
- Our customers all use another 3rd party based web form which needs the same data which our app is already capturing. They would like to be able to use our app to prepopulate the fields in the web form (so they don't have to manually enter all the data and/or paste it into the individual fields.). I know there must be a way to do this since I have seen Nortons Password Manager do the same thing (capture and save my frequently used form data and then populate 3rd party web forms on the fly for me).
Any Idea's or methods from the Guru's greatly appreciated!
TIA,
Don
