  • Article

[WCF RIA Services Version 1 Service Pack 2 is compatible with either .NET framework 4 or .NET Framework 4.5, and with either Silverlight 4 or Silverlight 5.]

Cancels an asynchronous Login operation.

Namespace:  System.ServiceModel.DomainServices.Client.ApplicationServices
Assembly:  System.ServiceModel.DomainServices.Client (in System.ServiceModel.DomainServices.Client.dll)

Syntax

'Declaration
Protected Friend Overridable Sub CancelLogin ( _
    asyncResult As IAsyncResult _
)

'Usage
Dim asyncResult As IAsyncResult

Me.CancelLogin(asyncResult)

protected internal virtual void CancelLogin(
    IAsyncResult asyncResult
)

protected public:
virtual void CancelLogin(
    IAsyncResult^ asyncResult
)

abstract CancelLogin : 
        asyncResult:IAsyncResult -> unit 
override CancelLogin : 
        asyncResult:IAsyncResult -> unit 

 function CancelLogin(
    asyncResult : IAsyncResult
)

Parameters

Exceptions

Exception Condition
InvalidOperationException

asyncResult was not returned from BeginLogin or the asynchronous call has already been concluded with a previous call to cancel or end.
NotSupportedException

SupportsCancellation is false.

Remarks

When you override this method, you do not need to call the base method. This method is invoked when a Login operation is canceled. Either this method or EndLogin will be invoked to conclude the operation, but not both. After CancelLogin is called, the callback passed in to BeginLogin should not be invoked. Exceptions thrown from this method will be available in Error.
