ProjectContext.WaitForQueue method
Waits for the specified queue job to complete, or for a maximum number of seconds.
Namespace: Microsoft.ProjectServer.Client
Assembly: Microsoft.ProjectServer.Client (in Microsoft.ProjectServer.Client.dll)
Syntax
'Declaration
Public Function WaitForQueue ( _
job As QueueJob, _
timeoutSeconds As Integer _
) As JobState
'Usage
Dim instance As ProjectContext
Dim job As QueueJob
Dim timeoutSeconds As Integer
Dim returnValue As JobState
returnValue = instance.WaitForQueue(job, _
timeoutSeconds)
public JobState WaitForQueue(
QueueJob job,
int timeoutSeconds
)
Parameters
job
Type: Microsoft.ProjectServer.Client.QueueJobAn object that represents the queued job.
timeoutSeconds
Type: System.Int32The maximum number of seconds to wait for the queue job to complete.
Return value
Type: Microsoft.ProjectServer.Client.JobState
The state of the queue job. If the job completes successfully, returns JobState.Success.
Examples
The Console example named QueueCreateProject does the following jobs:
Parses the command line to get the name of a new project, and an optional queue job wait time. The default wait time is 10 seconds. For example, if a project named Test proj 1 does not exist in Project Web App, you can run the application with the QueueCreateProject -projName "Test proj 1" command.
Creates a ProjectContext object for the specified Project Web App instance.
Gets the GUID of the enterprise project type (EPT) named "Basic Project Plan".
Creates a project by using the CreateTestProject method, which sets the properties of a ProjectCreationInformation object.
Waits for the Project Server Queue Service to publish the new project, by using the ProjectContext.WaitForQueue method.
Lists the published projects. If the QueueCreateProject application does not call the WaitForQueue method, the published projects may not yet include the new project.
For more information about this example, see Getting started with the Project Server CSOM and .NET.
