IWMPSettings.isAvailable (VB and C#)
[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 It has been superseded by MediaPlayer.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 isAvailable property (the get_isAvailable method in C#) gets a value that indicates whether a specified action can be performed.
[Visual Basic]
ReadOnly Property isAvailable(

Remarks
IWMPSettings.isIdentical is a property in Visual Basic that takes a parameter. In C# it is referred to as the IWMPSettings.get_isIdentical method.
Examples
The following example tests each of the IWMPSettings properties using the isAvailable property (the get_isAvailable method in C#). The property name and the result of each test are displayed in a multi-line text box. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.
// Create a string array that contains a list of IWMPSettings properties.
string[] propertyList = new string[12]{
"AutoStart", "Balance", "BaseURL", "DefaultFrame", "EnableErrorDialogs",
"GetMode", "InvokeURLs", "Mute", "PlayCount", "Rate", "SetMode", "Volume"
};
// Create another string array of the same size to hold the result of each
// call to get_isAvailable.
string[] results = new string[12];
// Test each property using get_isAvailable and add the name of the property
// and the result of the test to the results array.
for (int i = 0; i < propertyList.Length; i++)
{
bool isAvailable = player.settings.get_isAvailable(propertyList[i]);
results[i] = (propertyList[i] + " = " + isAvailable.ToString());
}
// Display the results in a multi-line text box.
playerSettings.Lines = results;
' Create a string array that contains a list of IWMPSettings properties.
Dim propertyList As String() = New String(11) { _
"AutoStart", "Balance", "BaseURL", "DefaultFrame", "EnableErrorDialogs", _
"GetMode", "InvokeURLs", "Mute", "PlayCount", "Rate", "SetMode", "Volume" _
}
' Create another string array of the same size to hold the result of each
' call to get_isAvailable.
Dim results(12) As String
' Test each property using isAvailable and add the name of the property
' and the result of the test to the results array.
For i As Integer = 0 To (propertyList.Length - 1)
Dim isAvailable As Boolean = player.settings.isAvailable(propertyList(i))
results(i) = (propertyList(i) + " = " + isAvailable.ToString())
Next i
' Display the results in a multi-line text box.
playerSettings.Lines = results
