我有一个项目正在逐步进行。对于此步骤,我试图使程序在一定数量的行(我正在使用For循环)中重复一定次数(我尝试使用“直到循环”)。 。行数比我希望程序循环的次数大(大得多)。我尝试使用两个循环的原因是因为我想在i范围的每一行中搜索各种条件,但我只想更改前n个匹配项。因为我不知道比赛在哪里或相距多远,所以我需要搜索9000+的整个范围。
到目前为止,仅for循环有效,但是我不知道如何成功添加Do Before循环。我在内部和外部都尝试过For循环,但没有一个起作用。
在此示例中,for循环位于内部。本来应该做9,却做了9,057(E的值):
Sub Hilight()
Dim usch As Worksheet
Set usch = Worksheets("USCH attributes")
Dim m As Worksheet
Set m = Worksheets("Maps")
Dim i As Integer
Dim E As Integer
Dim n As Integer
Dim s1 As String
Dim s2 As String
Dim s3 As String
s1 = Range("U1").Value
s2 = Range("V1").Value
s3 = Range("W1").Value
Dim rU As String
Dim rE As String
Dim rA As String
rU = m.Range("D4").Value
rE = m.Range("D3").Value
rA = m.Range("D2").Value
E = Range("S1").Value
n = 0
Do Until n >= 9
For i = 1 To E
n = n + 1
Debug.Print n
If Cells(i, 15).Value = s3 And Cells(i, 13).Value = rA And Cells(i, 11) = "" Then
Cells(i, 15).Interior.ColorIndex = 0
End If
Next i
Loop
End Sub
下一个外部带有for循环的示例看起来更好一些,我猜呢?调试最多只能打印9个,所以很好。不幸的是,For循环似乎根本没有运行,因为没有改变颜色。 (仅粘贴内部代码,因为所有暗调都相同)
For i = 1 To E
Do Until n >= 9
n = n + 1
Debug.Print n
If Cells(i, 15).Value = s3 And Cells(i, 13).Value = rA And Cells(i, 11) = "" Then
Cells(i, 15).Interior.ColorIndex = 37
End If
Loop
Next i
我考虑过将n = 0放入循环中,但这只会打印1九千次,对吧?
你们能帮我解决这个问题以使其正常运行吗?我已经阅读了三天的循环教程,但无法正常工作:(非常感谢您的帮助!

I've no idea if I'm reading your question correctly so this is a guess at your requirement.
The following reads all the lines (E
) but keeps count of how many matches/changes in n
and stops making those changes when n
becomes higher than 9.
n = 0
For i = 1 To E
If n < 10 And Cells(i, 15).Value = s3 And Cells(i, 13).Value = rA And Cells(i, 11) = "" Then
Cells(i, 15).Interior.ColorIndex = 0
n = n + 1
End If
Next i

根据您的实际操作,在Excel中循环行的行和列是一项标准任务。假设您的任务是在20个Excel列中生成一些数据,如下所示:
然后您的任务是遍历每行的每一列,并将其着色为红色(如果可以将其除以7):
然后,一个带有2个嵌套循环的解决方案可能是最简单的决定-一个循环用于行,每一行循环遍历各列:
Public Sub GenerateSomeData()
Dim someRows As Long
Dim someCols As Long
Cells.Clear
'GenerateSomeData
For someRows = 1 To 100
For someCols = 1 To 20
Cells(someRows, someCols) = someRows + someCols
Next someCols
Next someRows
'Search for values divisable by 7:
For someRows = 1 To 100
For someCols = 1 To 20
If Cells(someRows, someCols) Mod 7 = 0 Then
Cells(someRows, someCols).Interior.Color = vbRed
End If
Next someCols
Next someRows
End Sub

我想,我会做一些与CLR提供的答案非常相似的事情,但是会像下面这样稍作更改,因此您将经历i = 1 to E
,但是一旦n = 9
我就会退出循环为了节省资源:
n = 0
For i = 1 To E
If Cells(i, 15).Value = s3 And Cells(i, 13).Value = rA And Cells(i, 11) = "" Then
Cells(i, 15).Interior.ColorIndex = 37
n = n + 1
End If
If n = 9 Then Exit For
Next i
