IWMPControls.isAvailable (VB and C#)

The isAvailable property (the get_isAvailable method in C#) gets a value indicating whether a specified type of information is available or a specified action can be performed.

Parameters

bstrItem

A System.String that is one of the following values.

Value Description
currentItem Discovers whether the user can set the IWMPControls.currentItem property.
currentMarker Discovers whether the user can seek to a specific marker.
currentPosition Discovers whether the user can seek to a specific position in the file. Some files do not support seeking.
fastForward Discovers whether the file supports fast forwarding and whether that functionality can be invoked. Many file types (and live streams) do not support fastForward.
fastReverse Discovers whether the file supports fastReverse and whether that functionality can be invoked. Many file types (and live streams) do not support fastReverse.
next Discovers whether the user can seek to the next entry in a playlist.
pause Discovers whether the IWMPControls.pause method is available.

previous Discovers whether the user can seek to the previous entry in a playlist.

Property Value

A System.Boolean that indicates whether a specified type of information is available or a specified action can be performed.

Remarks

IWMPControls.isAvailable is a property in Visual Basic that takes a parameter. In C# it is referred to as the IWMPControls.get_isAvailable method.

Example Code

The following example uses the isAvailable property (the get_isAvailable method in C#) to verify that the current media item supports the currentPosition property. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.

  

' If the currentPosition property is supported, seek to position 0.
If (player.Ctlcontrols.isAvailable("currentPosition")) Then

    player.Ctlcontrols.currentPosition = 0

End If

// If the currentPosition property is supported, seek to position 0.
if (player.Ctlcontrols.get_isAvailable("currentPosition"))
{
    player.Ctlcontrols.currentPosition = 0;
}
