我有一个变量从一个子程序传递给另一个子程序时出现问题。我已经宣布它们是公开的,但似乎并不奏效。它说子程序超出范围。我需要的是在我的第二个子程序中使用varUnique(一个数组)和firstIndex。我需要做什么来完成这个任务?VBA子程序不能传递变量
Public fistIndex As Integer
Public varUnique As Variant
Sub FindUnique()
Dim varIn As Variant
Dim iInCol As Long
Dim iInRow As Long
Dim iUnique As Long
Dim nUnique As Long
Dim isUnique As Boolean
Dim lastIndex As Integer
varIn = Range("List")
ReDim varUnique(1 To UBound(varIn, 1) * UBound(varIn, 2))
nUnique = 0
For iInRow = LBound(varIn, 1) To UBound(varIn, 1)
For iInCol = LBound(varIn, 2) To UBound(varIn, 2)
isUnique = True
For iUnique = 1 To nUnique
If varIn(iInRow, iInCol) = varUnique(iUnique) Then
isUnique = False
Exit For
End If
Next iUnique
If isUnique = True Then
nUnique = nUnique + 1
varUnique(nUnique) = varIn(iInRow, iInCol)
End If
Next iInCol
Next iInRow
'// varUnique now contains only the unique values.
'// Trim off the empty elements:
ReDim Preserve varUnique(1 To nUnique)
firstIndex = LBound(varUnique)
lastIndex = UBound(varUnique)
create:
If Not varUnique(firstIndex) = "Sub-Total" Then
Worksheets.Add.Name = varUnique(firstIndex)
Call Ledge(varUnique, firstIndex)
Else
End
End If
If Not firstIndex = lastIndex Then
firstIndex = firstIndex + 1
ActiveCell.Offset(1, 0).Select
GoTo create
Else
End If
End Sub
Sub Ledge(varUnique, firstIndex)

** a)**使用函数返回值而不是从'Sub'中设置全局变量。好的代码没有全局变量。 ** b)**也许你应该把变量'firstIndex'称为变量,而不是有时调用它'fistIndex'。使用'Option Explicit'并查看会发生什么。实际上你真的应该在你编写的所有VBA代码中使用它。 – Tomalak
@Tomalak告诉人们,好的代码没有全局变量是没有用的。或者是真的。将全局变量取出不会使糟糕的代码变得更好,并且使用全局变量不会使代码变得糟糕。另外,你对'Option Explicit'完全正确。 –
@ Seith是的,关于golbal变量的部分有点争论。无论如何,我认为避免在全局变量中保持状态是一个好习惯,特别是作为初学者,特别是在上述情况下。对于所有事情来说,使用全局变量都很容易,也很诱人,而且可以从中得到一点好处。 – Tomalak
