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

Syntax

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

'Usage
Dim asyncResult As IAsyncResult

Me.CancelSaveUser(asyncResult)

protected internal virtual void CancelSaveUser(
    IAsyncResult asyncResult
)

protected public:
virtual void CancelSaveUser(
    IAsyncResult^ asyncResult
)

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

 function CancelSaveUser(
    asyncResult : IAsyncResult
)

Parameters

Exceptions

Exception Condition
InvalidOperationException

asyncResult was not returned from BeginSaveUser 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 SaveUser operation is canceled. Either this method or EndSaveUser will be invoked to conclude the operation, but not both. After CancelSaveUser is called, the callback passed in to BeginSaveUser should not be invoked. Exceptions thrown from this method will be available in Error.
