PRJ4: Add Method Returns Wrong Resource Assignment UniqueID

ID: Q137167

Microsoft Project for Windows, version 4.0
Microsoft Project for Windows 95, version 4.1
Microsoft Project for Macintosh, version 4.0

SYMPTOMS

In Microsoft Project, when you run a macro to return the UniqueID property of a resource assignment (Assignments collection), an incorrect number may be returned.

CAUSE

This problem occurs if you use the Add method to return the unique ID for a resource assignment if the resource has been assigned to the task multiple times. For example, if you run the following macro

   Sub Macro1()
      Dim X as Object
      ' Add resource to task and set variable X equal to first
      ' resource assignment
      Set X = Projects(1).Tasks(1).Assignments.Add(1,1)
      ' Display unique ID for first resource assignment
      MsgBox X.UniqueID
      ' Add resource to task a second time and set
      ' variable X equal to second resource assignment
      Set X = Projects(1).Tasks(1).Assignments.Add(1,1)
      ' Display unique ID for second resource assignment
      MsgBox X.UniqueID
   End Sub

the second dialog box that should return the unique ID of the second resource assignment (2) displays the value 1 instead.

The Add method returns the first assignment for the task when you assign a resource multiple times.

WORKAROUNDS

To work around this problem, use the specific Assignments object to return the UniqueID property as in the following example:

   ' Assignments(2) is the second resource assignment
   ' for the first task
   MsgBox Projects(1).Tasks(1).Assignments(2).UniqueID
