Yes - if you run the following code on your project, it will produce a dialogue box stating how many dependencies have been defined in the project:
Sub CountDependencies()
Dim i_RelationshipCount As Integer
Dim tsk As Task
Dim tsk_dep As TaskDependency
i_RelationshipCount = 0
For Each tsk In ActiveProject.Tasks
If tsk Is Nothing Then GoTo NextTask
For Each tsk_dep In tsk.TaskDependencies
'only count predecessors (otherwsie will count each realtionship twice)
If tsk_dep.To = tsk Then
i_RelationshipCount = i_RelationshipCount + 1
End If
Next tsk_dep
NextTask:
Next tsk
MsgBox i_RelationshipCount & " dependencies/relationships exist in this schedule."
End Sub
