Current information about Live Connect is now available in the Windows Live Developer Center. The information in the following sections is provided for legacy purposes only.

Describes the result of an asynchronous request.

Feature:  Microsoft.Live
Namespace:  Microsoft.Live

The JavaScript Library for Windows Live Messenger Connect is built by using the Microsoft Ajax Library. Microsoft Ajax exposes a type system that enables you to add object-oriented capabilities to your JavaScript code. To learn more about creating and using enumerations, see Creating Custom Client Script by Using the Microsoft Ajax Library.

// Declaration:
Microsoft.Live.AsyncResultCode = function() {};
Microsoft.Live.AsyncResultCode.prototype = {
    success : 0,
    failure : 1

// Usage:
if (Microsoft.Live.AsyncResultCode.failure == value) {


Use AsyncResultCode values to update the web page after an asynchronous operation is completed, for example, when a user signs in. The SignInCompletedEventArgs class has a resultCode property that returns the AsyncResultCode value.

The following example demonstrates a function that is called after sign in is completed. The resultCode value is one of the AsyncResultCode values.

function signInComplete(signInCompletedEventArgs) {
    try {
        var resultCode = signInCompletedEventArgs.get_resultCode();
        switch (resultCode) {
            case Microsoft.Live.AsyncResultCode.success:
                // Success code path.
                dataContext = signInCompletedEventArgs.get_dataContext();
                dataContext.loadAll(Microsoft.Live.DataType.contacts, function() {
                    alert("Contacts loaded.");
            case Microsoft.Live.AsyncResultCode.failure:
                var error = signInCompletedEventArgs.get_error();
    } catch (ex) {
        // Log error.
