网络电视电视猫:[VBA]关于查找方法(Find方法)的应用示例补充

[内容]Find方法是查找Excel工作表中相应条件值的很有用的一个方法，它与Offset函数一起使用能够设置与所查找单元格相关的单元格。下面是一些示例。

---

[示例1]查找值并选中该值所在的单元格
[示例1-1]
Sub Find_First()
    Dim FindString As String
    Dim rng As Range
    FindString = InputBox("请输入要查找的值:")
    If Trim(FindString) <> "" Then
        With Sheets("Sheet1").Range("A:A")
            Set rng = .Find(What:=FindString, _
                            After:=.Cells(.Cells.Count), _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlNext, _
                            MatchCase:=False)
            If Not rng Is Nothing Then
                Application.Goto rng, True
            Else
                MsgBox "没有找到!"
            End If
        End With
    End If
End Sub
示例说明：运行程序后，将在工作表Sheet1的A列中查找InputBox函数输入框中所输入的值，并查找该值所在的第一个单元格，如果没有找到该值，则显示消息框“没有找到!”。语句Application.Goto rng, True的作用是将窗口滚动至该单元格，即该单元格位于当前窗口的左上方。
[示例1-2]
Sub Find_Last()
    Dim FindString As String
    Dim rng As Range
    FindString = InputBox("请输入要查找的值")
    If Trim(FindString) <> "" Then
        With Sheets("Sheet1").Range("A:A")
            Set rng = .Find(What:=FindString, _
                            After:=.Cells(1), _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlPrevious, _
                            MatchCase:=False)
            If Not rng Is Nothing Then
                Application.Goto rng, True
            Else
                MsgBox "Nothing found"
            End If
        End With
End If
示例说明：与上面的程序不同的是，运行该程序后，将在工作表Sheet1的A列中查找InputBox函数输入框中所输入的值，并选中该值所在的最后一个单元格。请比较代码中Find方法的参数。
[示例1-3]
Sub Find_Todays_Date()
    Dim FindString As Date
    Dim rng As Range
    FindString = Date
    With Sheets("Sheet1").Range("A:A")
        Set rng = .Find(What:=FindString, _
                        After:=.Cells(.Cells.Count), _
                        LookIn:=xlFormulas, _
                        LookAt:=xlWhole, _
                        SearchOrder:=xlByRows, _
                        SearchDirection:=xlNext, _
                        MatchCase:=False)
        If Not rng Is Nothing Then
            Application.Goto rng, True
        Else
            MsgBox "没有找到!"
        End If
    End With
End Sub
示例说明：运行程序后，将在工作表Sheet1的A列中查找日期所在的单元格，并选中第一个日期单元格。

[示例2]在B列中标出A列中有相应值的单元格
Sub Mark_cells_in_column()
    Dim FirstAddress As String
    Dim myArr As Variant
    Dim rng As Range
    Dim I As Long
 
    Application.ScreenUpdating = False
    myArr = Array("VBA")
   '也能够在数组中使用更多的值,如下所示
    'myArr = Array("VBA", "VSTO")
    With Sheets("Sheet2").Range("A:A")

        .Offset(0, 1).ClearContents
        '清除右侧单元格中的内容
 
        For I = LBound(myArr) To UBound(myArr)
            Set rng = .Find(What:=myArr(I), _
                            After:=.Cells(.Cells.Count), _
                            LookIn:=xlFormulas, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlNext, _
                            MatchCase:=False)
            '如要想查找rng.value中的一部分,可使用参数值xlPart
            '如果使用LookIn:=xlValues,也会处理公式单元格中与条件相同的值
 
            If Not rng Is Nothing Then
                FirstAddress = rng.Address
                Do
                    rng.Offset(0, 1).Value = "X"
                    '如果值VBA找到,则在该单元格的右侧列中的相应单元格作上标记
                    Set rng = .FindNext(rng)
                Loop While Not rng Is Nothing And rng.Address <> FirstAddress
            End If
        Next I
    End With
    Application.ScreenUpdating = True
End Sub
示例说明：运行程序后，将查找工作表Sheet2上A列中的每个单元格，并在值为“VBA”所在的单元格的右侧单元格中作出标记“X”。

[示例3]为区域中指定值的单元格填充颜色
Sub Color_cells_in_Range()
    Dim FirstAddress As String
    Dim MySearch As Variant
    Dim myColor As Variant
    Dim rng As Range
    Dim I As Long
 
    MySearch = Array("VBA")
    myColor = Array("3")
 
   '也能在数组中使用多个值
    'MySearch = Array("VBA", "Hello", "OK")
    'myColor = Array("3", "6", "10")
 
    With Sheets("Sheet3").Range("A1:C4")
 
        '将所有单元格中的填充色改为无填充色
        .Interior.ColorIndex = xlColorIndexNone
       
         For I = LBound(MySearch) To UBound(MySearch)
            Set rng = .Find(What:=MySearch(I), _
                            After:=.Cells(.Cells.Count), _
                            LookIn:=xlFormulas, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlNext, _
                            MatchCase:=False)
            '如果想查找rng.value的一部分,则使用参数值xlPart
            '如果使用LookIn:=xlValues,则也会处理公式单元格
 
            If Not rng Is Nothing Then
                FirstAddress = rng.Address
                Do
                    rng.Interior.ColorIndex = myColor(I)
                    Set rng = .FindNext(rng)
                Loop While Not rng Is Nothing And rng.Address <> FirstAddress
            End If
        Next I
    End With
End Sub
示例说明：运行程序后，将在工作表Sheet3上的单元格区域A1：C4中查找含有“VBA”的单元格，并将这些单元格填充为红色。如示例中的注释所提示的，也可以使用数组，将不同的值所在的单元格标记为不同的颜色。
也可以添加下面的语句，改变单元格中文本的颜色：
.Font.ColorIndex=0
.Font.ColorIndex=myColor(I)
