WMP Component - How to use components?

[eros]

I've loaded the WMP component but I don't understand how to use the objects and interfaces (newbie in OOP).

For instance, if I want to get the height of a video file, I know I need to get it from imageSourceHeight property in the Media object, but I don't know how.

What do I need to do?

Thx

This is the example from the SDK documentation, the script used is pretty straight forward to read and understand.

Syntax

player.currentMedia.imageSourceHeight

Possible Values

This property is a read-only Number (long).

Remarks

If the media item is not the current one, this property returns zero.

To retrieve the value of this property, read access to Media Library is required. For more information, see Media Library Access.

Example Code

The following JScript example uses Media.imageSourceHeight to display the image size, in pixels, of the current media item. The information is printed to an HTML TEXTAREA element named VideoSize. The Player object was created with ID = "player".

<!-- Create an event handler to refresh the information when the current media changes. -->
<SCRIPT LANGUAGE = "JScript" FOR = Player EVENT = OpenStateChange(NewState)>

// Test whether the new media item is open.
if (NewState == 13){

// Store the height and width of the new media item.
var Height = Player.currentMedia.imageSourceHeight;
var Width = Player.currentMedia.imageSourceWidth;

// Erase the information in the text area.
VideoSize.value = "";

// Test whether an image is visible.
if (Height != 0 && Width != 0)

// Display the image size information.
VideoSize.value = Width + " x " + Height;
}
</SCRIPT>

Version: Windows Media Player version 7.0 or later.
