WorkflowApplication.BeginLoadRunnableInstance Method (AsyncCallback, Object)

Initiates an operation to load a runnable workflow instance from the InstanceStore.

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

Public Function BeginLoadRunnableInstance ( _
	callback As AsyncCallback, _
	state As Object _
) As IAsyncResult


Type: System.AsyncCallback
The method to be called when the operation is complete.
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(IAsyncResult). EndLoadRunnableInstance(IAsyncResult) can be called from inside or outside of the callback method. If EndLoadRunnableInstance(IAsyncResult) is called before the resume operation completes, it blocks until the resume operation completes. By default, the resume operation must complete in 30 seconds or else a TimeoutException is thrown from EndLoadRunnableInstance(IAsyncResult).

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