    ResponseNamespace = "https://schemas.microsoft.com/office/project/server/webservices/QueueSystem/", 
    Use = SoapBindingUse.Literal, ParameterStyle = SoapParameterStyle.Wrapped)]
public void CancelJob(
    Guid jobUID,
    bool cancelCorrelationJobs,
    bool cancelSendIncompleteJobs
)

Parameters

• jobUID
  Type: System.Guid
  Queue job GUID.

• cancelCorrelationJobs
  Type: System.Boolean
  If true, cancel correlated jobs.

• cancelSendIncompleteJobs
  Type: System.Boolean
  If true, also cancel jobs that are still getting queued (the JobState is SendIncomplete).

Remarks

CancelJob sets the job completion state (JobState) of the specified job to Canceled. If cancelCorrelationJobs is false, the result is functionally equivalent to setting the state to FailedNotBlocking; that is, the current job failed, but correlated jobs farther down the queue continue to process.

Note

There is a potential race condition between checking the state of a job and calling CancelJob. When an application checks the state of a job, the state might be ReadyForProcessing. Before calling CancelJob, the state can switch to Processing or any other state.
