WorkflowApplication.BeginRun Method

Definition

Starts or resumes a workflow instance asynchronously using the IAsyncResult asynchronous design pattern.

Overloads

BeginRun(AsyncCallback, Object)

Starts or resumes a workflow instance asynchronously using the specified callback method and user-provided state.

BeginRun(TimeSpan, AsyncCallback, Object)

Starts or resumes a workflow instance asynchronously using the specified time-out interval, callback method, and user-provided state.

Remarks

For more information, see Asynchronous Programming Overview.

BeginRun(AsyncCallback, Object)

Starts or resumes a workflow instance asynchronously using the specified callback method and user-provided state.

public:
 IAsyncResult ^ BeginRun(AsyncCallback ^ callback, System::Object ^ state);
public IAsyncResult BeginRun (AsyncCallback callback, object state);
member this.BeginRun : AsyncCallback * obj -> IAsyncResult
Public Function BeginRun (callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

callback
AsyncCallback

The method to be called when the resume operation has completed.

state
Object

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

Returns

A reference to the asynchronous run operation.

Remarks

To determine whether the run operation was successful, call EndRun. EndRun can be called from inside or outside of the method referenced in the callback parameter. If EndRun 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 a TimeoutException is thrown from EndRun.

This method starts or resumes a workflow asynchronously using the IAsyncResult asynchronous design pattern. For more information, see Asynchronous Programming Overview.

BeginRun(TimeSpan, AsyncCallback, Object)

Starts or resumes a workflow instance asynchronously using the specified time-out interval, callback method, and user-provided state.

public:
 IAsyncResult ^ BeginRun(TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);
public IAsyncResult BeginRun (TimeSpan timeout, AsyncCallback callback, object state);
member this.BeginRun : TimeSpan * AsyncCallback * obj -> IAsyncResult
Public Function BeginRun (timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

timeout
TimeSpan

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

callback
AsyncCallback

The method to be called when the resume operation has completed.

state
Object

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

Returns

A reference to the asynchronous run operation.

Remarks

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