VBA EXCEL为表达式设置两个变量的多个嵌套FOR循环

Question

好的，我已经做了大量的搜索，找到了一些，玩了很少。我似乎不能让这些循环完全工作，我可以在部分或另一个上，但不是整个。正如第一个循环工作正常，然后它变得摇摇欲坠。

T是表达式输出t.Value = time1 - time2的目标

Y是一个不会更改= time1的设置时间和日期

X是时间和日期，必须从与相应y相同的列的范围中提取。x= time 2

我已经上传了我的工作簿的相应片段

https://docs.google.com/open?id=0BzGnV1BGYQbvMERWU3VkdGFTQS1tYXpXcU1Mc3lmUQ

我尝试过重新安排for循环的条件退出。我甚至考虑过尝试goto，直到我注意到它的提及造成了一大堆身体。

我乐于接受任何建议或指导，并对此表示感谢。我注意到有几种语言有退出和继续选项，但VB没有吗？

这是我的循环，我在试着让它工作时，把我弄得乱七八糟的东西去掉了。

Sub stituterangers()
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

For Each t In range("d7:cv7")
       For Each x In range("d8:cv11")
             If x > 0 Then time2 = x           
           For Each y In range("d2:cv2")
            time1 = y                     
        t.Value = time1 - time2
        t = 0
                Next y
      Next x
Next t
End Sub 


Sub stituterangersNEW()
Dim t As range
Dim x As range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

On Error Resume Next

    'Looping through each of our output cells.
    For Each t In range("d7:cv7")



     For Each y In range("d2:cv2")
            If t.Column = y.Column Then
            time1 = y.Value
             If y = 0 Then Exit Sub
                End If

        For Each x In range("d8:cv11")
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then

                If x > 0 Then
                    time2 = x.Value

                    t.Value = time1 - time2

                    Exit For
                End If
            End If


            Next x

        Next y
    Next t

End Sub

我现在无法访问您的google docs文件，但您的代码有一些问题，我将在回答时尝试解决这些问题

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.
        '(Only one row in your example. This can be adjusted if needed.)
        For Each x In Range("B2:E2") 'Change these to match your real ranges.
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then
                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2
                    'Exit out of this loop and move to the next output cell.
                    Exit For
                End If
            End If
            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

我更改了您的工作表以进行操作(有关新的Sub，请参阅上文)。这可能不能直接满足您的需求，但希望它能演示我认为您想要做的事情背后的概念。请记住，此代码并不遵循我推荐的所有编码最佳精度(例如，验证时间实际上是一个时间，而不是某个随机的其他数据类型)。

     A                      B                   C                   D                  E
1    LOAD_NUMBER            1                   2                   3                  4
2    DEPARTURE_TIME_DATE    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 19:30    11/12/2011 20:00                
4    Dry_Refrig 7585.1  0   10099.8 16700
6    1/4/2012 19:30

使用sub，我得到了以下输出：

    A           B             C             D             E
7   Friday      1272:00:00    1272:00:00    1272:00:00    1271:30:00
8   Saturday    1272:00:00    1272:00:00    1272:00:00    1271:30:00
9   Thursday    1272:00:00    1272:00:00    1272:00:00    1271:30:00
