我试图展示相关项目活动的路径。基本上你可以把它想象成一个有向图。我做了一个邻接矩阵。
STA A1.1 A1.2 ...
STA 0 1 0 ...
A1.1 0 0 1 ...
A1.2 0 0 0 ...
... ... ... ... ...
然后我编写了一个子程序来查找所选活动的前身,但我真正需要的是从一开始就显示所有相关活动。例如,如果选择 A1.2,它应该打印出 [STA, A1.1, A1.2]。如果选择了所有活动都超前的最终结果,则应以正确的顺序打印所有活动。不同的路径可以像这样分开 [STA, A1.1, A1.2, ... END],[STA, A2.1, A2.2, ... END],[STA, A3.1, . ..] 到目前为止,我的代码只打印出所选活动的前身:
'---------------------------------
Sub RunThings()
Application.ScreenUpdating = False
Call UserInput
Application.ScreenUpdating = True
End Sub
'---------------------------------
Sub UserInput()
Dim iReply As Variant
iReply = Application.InputBox(Prompt:="Please enter activity name", Title:="FIND ACTIVITY PATH", Type:=2)
'MsgBox (iReply)
If iReply = False Then
Exit Sub
Else 'They cancelled (VbCancel)
If iReply <> "" Then
Call Findpath(CStr(iReply))
End If
End If
Exit Sub
End Sub
'---------------------------------
Function FindRowCol(term As String, row As Boolean)
Dim SearchRange As Range
Dim FindRC As Range
If row = False Then
Set SearchRange = Range("A1", Range("T1").End(xlUp))
Else
Set SearchRange = Range("A1", Range("A65536").End(xlUp))
End If
Set FindRC = SearchRange.Find(term, LookIn:=xlValues, lookat:=xlWhole)
If row = False Then
FindRowCol = FindRC.Column
Else
FindRowCol = FindRC.row
End If
End Function
'---------------------------------
Sub Findpath(activity As String)
Application.ScreenUpdating = False
ActCol = FindRowCol(activity, False)
For i = 2 To 65536
If Cells(i, 1).Value = "" Then
LastRow = Cells(i, 1).row - 1
Exit For
End If
Next i
Dim Predecessors() As Variant
Dim Counter As Integer
Counter = 0
For j = 1 To LastRow
If Cells(j, ActCol).Value = 1 Then
Counter = Counter + 1
End If
Next j
ReDim Predecessors(1 To Counter)
Insert = 1
For j = 1 To LastRow
If Cells(j, ActCol).Value = 1 Then
Predecessors(Insert) = Cells(j, 1).Value
Insert = Insert + 1
End If
Next j
Dim CurrAct As String
For k = LBound(Predecessors) To UBound(Predecessors)
CurrAct = CStr(Predecessors(k))
MsgBox (CurrAct)
Next k
Application.ScreenUpdating = True
End Sub
'---------------------------------
我的问题是是否可以将子例程 Findpath 更改为递归函数以打印出所有相关活动?
这是完整的邻接矩阵:
