PRJ: TimeScaledData Method Example Run Time Error 91

• Microsoft Project for Windows, version 4.0
• Microsoft Project for the Macintosh, version 4.0

SYMPTOMS

The sample code for the TimeScaledData method in Visual Basic for Applications Help may produce a "Run Time Error 91" error message when you use it with projects that contain blank rows.

Under normal circumstances, this macro should run correctly and create a .CSV file.

CAUSE

The sample code for this macro does not take blank rows into account; therefore, the Run Time error is produced when the macro encounters a blank task row.

RESOLUTION

To work around this problem, add additional commands to the macro code that will trap the error situation. To trap the error, add "If Not (t is Nothing) then . . . end if" around the For Next loop in the macro. When you add this code, the error will be trapped and the example will run on files with blank task rows. The resulting code example looks like this:

Sub AssignmentsOverTime()
   Dim  t, r, temp

   Open "USAGE.CSV" For Output As #1

   For Each t In ActiveProject.Tasks
      If Not (t is Nothing) Then        'NEW LINE
         Print #1, t.Name
         For Each r In t.Resources
            temp = TimescaledData(t.ID, r.ID, ActiveProject.ProjectStart, _
                    ActiveProject.ProjectFinish, pjWork, pjTimescaleWeeks)
            Print #1, r.name & ListSeparator & temp
         Next r
      End If                            'NEW LINE
   Next t

   Close #1
End Sub
