Generic parameter two containing event-specific information. The use and possible values of the parameter depend on the MediaEventCode.
Creates an instance of the MediaEventArgs object.
Syntax
public MediaEventArgs( 
   MediaEventCode eventCode,
   long param1,
   long param2
)
'Declaration
 
Public Function New( _
   ByVal eventCode As MediaEventCode, _
   ByVal param1 As Long, _
   ByVal param2 As Long _
)
'Usage
 
Dim eventCode As MediaEventCode
Dim param1 As Long
Dim param2 As Long
 
Dim instance As New MediaEventArgs(eventCode, param1, param2)
public MediaEventArgs( 
   MediaEventCode eventCode,
   long param1,
   long param2
)
function MediaEventArgs( 
   eventCode ,
   param1 ,
   param2 
)
public:
MediaEventArgs( 
   MediaEventCode eventCode,
   int64 param1,
   int64 param2
)

Parameters

eventCode
The MediaEventCode identifying the type of media event that was raised.
param1
Generic parameter one containing event-specific information. The use and possible values of the parameter depend on the MediaEventCode.
param2
Generic parameter two containing event-specific information. The use and possible values of the parameter depend on the MediaEventCode.
