Project::ReadSchedulingContext method

Gets a list of projects that are related to specified projects or resources. A relationship exists if one of the following conditions is met:

• Projects share enterprise resources (either those on the project team or in the input list).

• Projects have interproject dependencies (cross-project links).

• Projects share resources with or have cross-project links with projects that are related to projects in the input list (an indirect relationship).

Project Server Permissions

Consider two projects that share one enterprise resource, as in the following table.

In the following code fragment for a test application, WebSvcProject is an arbitrary name for a reference to the Project web service, and project is an initialized instance of the WebSvcProject.Project class.

try
{
    Guid[] projectUids = { new Guid("a9d03b87-37f1-473d-90f6-77ba3c521a40") };
    Guid[] resourceUids = null;
    
    WebSvcProject.ProjectContextDataSet dsProjectContext =
        project.ReadSchedulingContext(projectUids, resourceUids);
    dsProjectContext.WriteXml(@"C:\Tests\SchedulingContextOut.txt");
}
catch (SoapException ex)
{
    . . .
}

The value of the Relationship element in the SchedulingContextOut.txt file shows that Project2 is related to Project1 by a shared resource. If you add one or both resource GUIDs to the resourceUids array, the result is the same.

Note
If you add both project GUIDs to the projectUids array, dsProjectContext is empty.
