Question

我有以下代码用于处理电子表格VBA宏上的用户表单：

Option Explicit
Public saved_vocab As String
Public saved_num As String
Public saved_def As String
Public saved_ex As String

Private Sub Save_Click()
    Dim low As Integer
    Dim high As Integer
    Dim selected As Integer

    low = 1
    high = Cells(1, 1).End(xlDown).Row
    Range(Cells(low, 1), Cells(high, 1)).Find(what:=vocab.Text, After:=ActiveCell, LookIn:=xlFormulas, _
          LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
          MatchCase:=False, SearchFormat:=False).Activate
    selected = ActiveCell.Row

    saved_vocb = Cells(selected, 1).Text
    saved_num = Cells(selected, 2).Text
    saved_def = Cells(selected, 3).Text
    saved_ex = Cells(selected, 4).Text
    Cells(selected, 1) = vocab.Text
    Cells(selected, 2) = num.Text
    Cells(selected, 3) = definition.Text
    Cells(selected, 4) = example.Text
End Sub

Private Sub undo_Click()
    Cells(selected, 1) = saved_vocab
    Cells(selected, 2) = saved_num
    Cells(selected, 3) = saved_def
    Cells(selected, 4) = saved_ex
End Sub

我想要做的是在保存的_ ???中正确保存信息当我决定单击“撤消”按钮执行第二个函数时，我可以正确访问它。但是，当我执行第二个函数时，先前保存的信息保存在_ ???变量可能不在我自己处理变量范围不正确的b / c。什么是最简单的方法来完成我想做的事情？提前感谢您的建议。

Answer 1

乍一看，我可以看到变量selected在Save_Click()子例程中声明，并在undo_Click()子例程中使用。

变量selected需要在子例程之外与您的其他全局变量（例如saved_vocab，saved_num等）一起声明。

Option Explicit
Public saved_vocab As String
Public saved_num As String
Public saved_def As String
Public saved_ex As String
Public selected As Integer 'declaration added

然后删除selected

中Save_Click()的现有声明

我认为您希望将全局变量放在“普通”模块中，而不是表单模块中。
