Project: AdjustDates Macro Incorrectly Reschedules Tasks

 * }

Q126103

The information in this article applies to:


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

SYMPTOMS
When you use the Microsoft Project AdjustDates macro, some tasks are not properly rescheduled to the correct dates.

"-or-" When you use a Visual Basic, Applications Edition, DateDifference, DateAdd, or DateSubtract method, incorrect values or dates are calculated.

CAUSE
The DateDifference, DateAdd, and DateSubtract methods, by default, always base calculations on the project's standard calendar instead of on the project calendar.

Note that the Help topics for these methods say that their calculations should be based on the project's calendar unless otherwise specified.

WORKAROUND
To force the DateDifference, DateAdd, and DateSubtract methods to base calculations on the project calendar instead of the project standard calendar, always specify the optional calendar parameter.

For example, use the following:

  DateDifference(startDate:= #1/1/94#, finishDate:= #1/31/94#, _                  Calendar:= ActiveProject.Calendar) Instead of:

  DateDifference(startDate:= #1/1/94#, finishDate:= #1/31/94#) NOTE: To correct the AdjustDates macro, search for all instances of DateAdd, DateSubtract, and DateDifference, and supply the optional third (calendar) parameter as "ActiveProject.Calendar."
