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.

Example Code

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.
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

// 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;
