Player.OpenStateChange event
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The OpenStateChange event occurs when the openState property changes value.
Syntax
Player.OpenStateChange(
NewState
)
Parameters
-
NewState
-
Number (long) specifying the new open state. See openState for a table of values.
Return value
This event does not return a value.
Remarks
Windows Media Player can go through several open states while it attempts to open a network file, such as locating the server, connecting to the server, and finally opening the file. This event will be fired each time the open state changes.
The value of event parameters is specified by Windows Media Player, and can be accessed or passed to a method in an imported JScript file using the parameter name given. This parameter name must be typed exactly as shown, including capitalization.
Windows Media Player states are not guaranteed to occur in any particular order. Furthermore, not every state necessarily occurs during a sequence of events. You should not write code that relies upon state order.
