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
