[英]Loop through Worksheets with similar name structure in VBA
我的Excel文件具有工作表的以下結構:
A1
A2
A3
A4
B1
B2
B3
C1
C2
C3
C4
C5
...
因此,您可以看到A的4倍,B的3倍,C的5倍,等等(均勻分布)
我想做的是遍歷工作表組並應用一些代碼。 在這種情況下,組內必須是相同的代碼,但組之間必須是不同的代碼,因此我不能簡單地同時遍歷所有工作表。
我知道如何在VBA中獲取工作表的名稱。 我的第一個想法是首先從組名的右邊“截去”數字(最后一個字符),然后確定結果的唯一組。 然后,我想為每個組循環,例如,第一個循環將從A1開始並在A4處停止。 但是,如何告訴VBA在名稱中標識一個非恆定的上限(在示例A4,B3,C5等)中呢?
也許那也不是最有效的方法。 如果可以的話,我什至可以將所有工作表重命名為其他系統,但是無論如何都必須使用編碼。 任何想法都受到高度贊賞。
簡而言之,我想做什么:
1)按名稱(在上例中為A,B,C)標識工作組的唯一組
2)對於每個組,循環瀏覽所有關聯的工作表並應用一些代碼
謝謝。
為了標識唯一的組,您可以執行一個循環,該循環查看工作表名稱,如果它具有“ A”,則執行X,“ B”,Y等。
Dim ws as Worksheet
For each ws in Activebook.Sheets
If ws.name like "A*" Then
** Code for "A" worksheets
Else If ws.name like "B" Then
** code for "B*" worksheets
Else If [...]
End if
Next ws
然后,您可以為每種工作表類型創建其他宏,並在上面的代碼中調用它。 即:
Private Sub A_Things()
msgbox("This is a sheet 'A' type")
[...whatever other code you want]
End Sub
Private Sub B_Things()
msgbox("This is a sheet 'B' type")
[...whatever other code you want]
End Sub
Sub checkSheets()
Dim ws as Worksheet
For each ws in Activebook.Sheets
If ws.name like "A*" Then
Call A_Things
Else If ws.name like "B" Then
Call B_Things
Else If [...]
End if
Next ws
End Sub
編輯:對於只希望在某些工作表上執行此操作或設置某些上限的部分...如果您確切知道要在哪些工作表上運行代碼,則可以將其放入數組中,然后運行代碼僅在該陣列中的圖紙上。
類似於(偽代碼):
Dim nameArray() as Variant
ReDim nameArray(4) 'Note, this can hold 5 values, so if you have X sheets, ReDim this to X-1 sheets
nameArray = Array("A1","A2","A4","B1","B3")
for i = 0 to UBound(nameArray())
'this will loop through Sheet A1, then A2, then A4, etc. and run the code below
If nameArray(i) = "A1" Then
[run A1 code]
ElseIf [...]
End If
Next i
我建議使用字典來定義組和每個組中的工作表計數。
這是一個主意:
Sub LoopThroughGroupsOfSheets()
'Needs reference to MS Scripting Runtime
Dim dic As Dictionary
Dim i As Integer, k As Integer
Dim wshName As String
'define Sheets for loop and count of them
Set dic = New Dictionary
dic.Add "A", 4
dic.Add "B", 3
dic.Add "C", 5
For k = 0 To dic.Count - 1
For i = 1 To dic.Items(k)
DoSomething dic.Keys(k) & i
Next
Next
End Sub
Sub DoSomething(wshName As String)
Debug.Print wshName
End Sub
結果:
SheetName: A1
SheetName: A2
SheetName: A3
SheetName: A4
SheetName: B1
SheetName: B2
SheetName: B3
SheetName: C1
SheetName: C2
SheetName: C3
SheetName: C4
SheetName: C5
還有一種方法..如果您的名字只是A-Z
Sub DoStuff()
Dim i As Integer
Dim counter As Integer
'loop through A to Z
For i = 65 To 90
counter = 1
'loop until we no longer have a valid sheet
Do While isWorksheet(Chr(i) + CStr(counter)) = True
'do work by calling the correct method
Run (setSubName(Chr(i)))
counter = counter + 1
Loop
Next i
End Sub
'check to see if the worksheet exists
Function isWorksheet(name As String) As Boolean
On Error GoTo wsError
Err.Clear
'just try and access the name
Sheets(name).name
wsError:
If Err.Number = 0 Then
isWorksheet = True
Else
isWorksheet = False
End If
End Function
'set the sub routine name to call
Function setSubName(value As String) As String
setSubName = Switch(value = "A", "Sub_A_Name", value = "B", "Sub_B_Name", _
value = "C", "Sub_C_Name", value = "D", "Sub_D_Name")
End Function
Sub Sub_A_Name()
'do work for group A
End Sub
