Application.GetCacheStatusForProject property (Project)

Gets the state of a specified job that the active cache in Project Professional sends to the Project Server Queue System. Read-only PjCacheJobState.

Syntax

expression. GetCacheStatusForProject

expression A variable that represents an Application object.

Parameters

Remarks

When you use Project Professional to perform an operation that uses one of the queue methods in Project Server, such as saving an update, publishing, or checking in a project, the Project Professional cache sends a job request to the Project Server Queue System. The GetCacheStatusForProject property exposes the status of the queue job.

Example

The TestCacheStatus macro in the following example saves the active project, calls WaitForJob to wait for the queue to finish successfully, and then publishes the project. The WaitForJob macro periodically checks the job state by calling GetCacheStatusForProject and prints the job status to the Immediate window. If it finds the same status more than ten times in succession, the WaitForJob macro assumes there is a problem and exits. The example uses a Sleep method that can be run in either a 64-bit Project installation or a 32-bit Project installation.

End Function

Following is the output for a wait time of 500 milliseconds between status messages. If the network latency is greater, set the wait time for a longer interval. To find the meaning of output values, see the PjCacheJobState enumeration. For example, the value 4 is the pjCacheJobStateSuccess constant. If you run TestCacheStatus when there are no changes made to the project, the save job state repeats many times as -1, which is the value of the pjCacheJobStateInvalid constant.

Save job state: 4
Save completed ...
Publish job state: -1
Publish job state: 3
Publish job state: 3
Publish job state: 4
Publish completed: WinProj test 1

Property value
