WorkflowApplication.BeginLoadRunnableInstance Method (TimeSpan, AsyncCallback, Object)

.NET Framework (current version)
 

Initiates an operation to load a runnable workflow instance from the InstanceStore using the specified time-out interval.

Namespace:   System.Activities
Assembly:  System.Activities (in System.Activities.dll)

public IAsyncResult BeginLoadRunnableInstance(
	TimeSpan timeout,
	AsyncCallback callback,
	object state
)

Parameters

timeout
Type: System.TimeSpan

The interval in which the load operation must complete before the operation is canceled and a TimeoutException is thrown.

callback
Type: System.AsyncCallback

The method to be called when the operation is complete.

state
Type: System.Object

An optional application-specific object containing information about the asynchronous operation.

Return Value

Type: System.IAsyncResult

A reference to the asynchronous operation

A runnable instance is an instance for which a timer or instance lock has expired.

To determine if the load operation was successful, call EndLoadRunnableInstance. EndLoadRunnableInstance can be called from inside or outside of the callback method. If EndLoadRunnableInstance is called before the resume operation completes, it blocks until the resume operation completes. If the load operation does not complete within the specified time-out interval a TimeoutException is thrown from EndLoadRunnableInstance.

This method loads a workflow asynchronously using the IAsyncResult asynchronous design pattern. For more information, seeAsynchronous Programming Overview.
