我正在尝试构建一个集合并从该集合中获取唯一值计数但是在构建集合本身时出错。任何人都可以建议我在哪里出错。请分享您的想法。请让我知道如何找出唯一值的COUNT。
Sub trial()
Dim sampleVisualBasicColl As Collection
For i = 2 To 10
Rng = Range("M" & i).value
StartsWith = Left(Rng, 3)
If StartsWith = "Joh" Then
sampleVisualBasicColl.Add Rng
Else
End If
Next
Debug.Print (sampleVisualBasicCol1)
End Sub

您需要创建集合并声明它。
Sub trial()
Dim myCol As Collection
Set myCol= New Collection ' creates the collection
For i = 2 To 10
Rng = Range("M" & i).value
StartsWith = Left(Rng, 3)
If StartsWith = "Joh" Then
myCol.Add Rng
Else
End If
Next
For each x in myCol
Debug.Print x
Next x
End Sub

使用集合,您只需将Joh添加到集合中,然后计算项目:
'Using a collection
Sub Col_test()
Dim cCol As Collection
Dim i As Long
Set cCol = New Collection
On Error GoTo Err_Handler
With ThisWorkbook.Worksheets("Sheet1")
For i = 2 To 20
If Left(.Cells(i, 13), 3) = "Joh" Then
cCol.Add .Cells(i, 13).Value, .Cells(i, 13).Value
End If
Next i
End With
Debug.Print cCol.Count
On Error GoTo 0
Exit Sub
Err_Handler:
Select Case Err.Number
Case 457 'This key is already associated with an element of this collection
Err.Clear
Resume Next
Case Else
MsgBox "Error " & Err.Number & vbCr & _
" (" & Err.Description & ") in procedure Col_test."
Err.Clear
End Select
End Sub
如果你想要每个项目的数量(Joh,Ben ......你还有其他什么),那就用一本字典:
'Using a dictionary.
Sub Dic_Test()
Dim dict As Object
Dim i As Long
Dim sValue As String
Dim key As Variant
Set dict = CreateObject("Scripting.Dictionary")
With ThisWorkbook.Worksheets("Sheet1")
For i = 2 To 20
If Len(.Cells(i, 13)) >= 3 Then
sValue = Left(.Cells(i, 13), 3)
If dict.exists(sValue) Then
dict(sValue) = dict(sValue) + 1
Else
dict(sValue) = 1
End If
End If
Next i
End With
For Each key In dict.keys
Debug.Print key & " = " & dict(key)
Next key
End Sub
注意:我在代码中使用Cells
而不是Range
。 Cells(2,13)
是M2(第13列,第2行)。
我觉得这个链接对词典很有帮助:https://excelmacromastery.com/vba-dictionary/
作为进一步更新(在接听回答之后)并使用您在此处提出的问题列表:Excel VBA - Formula Counting Unique Value error此代码与词典将返回Joh = 4, Ian = 3
'Using a dictionary.
Sub Dic_Test()
Dim dict As Object
Dim dictFinal As Object
Dim i As Long
Dim sValue As String
Dim key As Variant
Dim keyFinal As String
Set dict = CreateObject("Scripting.Dictionary")
Set dictFinal = CreateObject("Scripting.Dictionary")
'Get the unique values from the worksheet.
With ThisWorkbook.Worksheets("Sheet1")
For i = 2 To 20
If Len(.Cells(i, 13)) >= 3 Then
sValue = .Cells(i, 13).Value
If dict.exists(sValue) Then
dict(sValue) = dict(sValue) + 1
Else
dict(sValue) = 1
End If
End If
Next i
End With
'Count the unique values in dict.
For Each key In dict.keys
keyFinal = Left(key, 3)
If dictFinal.exists(keyFinal) Then
dictFinal(keyFinal) = dictFinal(keyFinal) + 1
Else
dictFinal(keyFinal) = 1
End If
Next key
For Each key In dictFinal.keys
Debug.Print key & " = " & dictFinal(key)
Next key
End Sub

嘿,这段代码会帮助你,因为它在Listbox中收集了唯一值,
Private Sub UserForm_Initialize() Dim cUnique As Collection 昏暗的范围 昏暗的细胞作为范围 Dim sh As Worksheet Dim vNum As Variant
设置sh = ThisWorkbook.Sheets(“Sheet1”) 设置Rng = sh.Range(“A2”,sh.Range(“A2”)。值=“John”。结束(xlDown))
设置cUnique =新集合
On Error Resume Next
对于Rng.Cells中的每个单元格 cUnique.Add Cell.Value,CStr(Cell.Value) 下一个细胞
On Error GoTo 0
对于cUnique中的每个vNum Me.ListBox1.AddItem vNum
下一个vNum 结束子
答案 3 :(得分:-1)
您尚未声明Variable Rng&我这些是最重要的事情。同时我想建议这个公式,
=总和(如果(频率(如果(Len(B2:B20)> 0,匹配(B2:B20,B2:B20,0),""),如果(Len(B2) :B20)>匹配(B2:B20,B2:B20,0),"",))> 0,1))
其数组公式如此完成,按Ctrl + shift + enter。
你也可以使用这个,
Sub CountUnique()Dim i,count,j As Integer count = 1 For i = 1 To 470 flag = False If count
1然后对于j = 1要计数如果Sheet1.Cells(i, 3).Value = Sheet1.Cells(j,11).Value然后标记 = True End If If j Else flag = False End If If flag = False Then Sheet1.Cells(count, 11).Value = Sheet1.Cells(i,3).Value count = count + 1 End IfNext i Sheet1.Cells(1, 15).Value = count End Sub
