LiveSound ASP.NET Server Control Information

This page includes information about the LiveSound Server Control, which is included in PowerWEB LiveControls for ASP.NET: 

[View LiveControl Demo]

The LiveSound server control has the ability to play a sound on a webpage from within a client remote scripted callback. This capability adds many new potential features to web application, for example:

• Play an alarm when a critical condition occurs in a web application. For example, if the web application is monitoring server traffic in real time, an alert can be played when the server becomes overloaded.
• Associate a sound effect with some user interface action. For example, if creating a chat application, a doorbell sound could be played when a new person enters the chat room, a chime could be played when a new message is received, etc.
• Associate a sound effect with an application state change. For example, an email application (such as Hotmail) could continually poll the server for new messages (using LiveTimer) and, when a new message is received, a sound could be played like Microsoft Outlook.
• Tie sound effects to button clicks, mouse actions, etc.

Browser Compatibility

LiveControls have been tested and are fully "callback-compatible" in the following browsers:

• Microsoft Internet Explorer 5.0+ for Windows
• Microsoft Interner Explorer 5.0+ for Macintosh
• Netscape 7.1+ for Windows
• Netscape 7.1+ for Macintosh OS X
• Mozilla 1.3+ for Windows
• Mozilla 1.3+ for Macintosh OS X
• Firefox for Windows
• Firefox for Macintosh OS X
• Camino for Macintosh OS X
• Konqueror based engines
• Galeon
• Opera 5.0+

If a browser which is not compatible accesses a page containing LiveControls, the controls will fall back to the standard ASP.NET functionality. For example, a LiveButton issues a transparent callback when clicked. If on a non-compatible page, the button will still be displayed, but will cause a standard postback when clicked.

Server Tag Example

The following tags demonstrate typical settings for initializing a LiveSound with a sound file.

<cc1:LiveSound id="LiveSound1" source="rock.wav" runat="server"></cc1:LiveSound>

Code-Behind Example

The following code demonstrates playing a sound on a button click.

private void LiveButton1_Click(object sender, System.EventArgs e)
{
   // Play the sound on a webpage
   LiveSound1.Play();
}
