VBA Excel输入框运行时错误13类型不匹配

Question

我有一个运行良好的宏。但我遇到的问题是 InputBox。当用户在 InputBox 之外按 CANCEL 或 X 时，宏会出错。 用户最多可以输入 15 个值进行搜索，输入 0 开始搜索。我想让它更健壮，这样我就不会遇到这些错误。请帮忙。

Sub FindValues()    
    Dim LSearchRow As Integer
    Dim rw As Integer, cl As Range, LSearchValue As Long, LCopyToRow As Integer
    Dim iHowMany As Integer
    Dim aSearch(15) As Long
    Dim i As Integer

    ' clear the sheets before it runs so to accurate number of funds opend.

    Sheet2.Cells.ClearContents
    Sheets("tier 2").Cells.ClearContents
    Sheets("tier 3").Cells.ClearContents
    Sheets("tier 4").Cells.ClearContents
    Sheets("tier 5").Cells.ClearContents

    FixC
    Sheet2.Cells.Clear
    Sheet1.Select
    iHowMany = 0
    LSearchValue = 99

    'this for the end user to input the required A/C to be searched

    Do While LSearchValue <> 0
        LSearchValue = InputBox("Please enter a value to search for. Enter a zero to indicate finished" & _
    "entry.", "Enter Search value")
        If LSearchValue <> 0 Then
            iHowMany = iHowMany + 1
            If iHowMany > 15 Then
                MsgBox "You are limited to 15 search numbers.", vbOKOnly, "Limit reached"
                iHowMany = 15
                Exit Do
            End If

定义一个字符串变量Dim LSearchString as String，并将你的InputBox的返回值赋值给它：LSearchString = InputBox(...)。现在您可以检查输入是否为数字：If IsNumeric(LSearchString) 并处理错误的输入。如果成功，您可以继续将其转换为整数：LSearchValue = CInt(LSearchString)。你要知道CInt()在参数不是数字时总是返回0。

以下代码 sn-p 是从您的代码中修改后的摘录。 错误的输入会被忽略。

更新

Dim LSearchValue As Integer
Dim LSearchString As String

'..........

LSearchValue = 99

Do While True
    LSearchString = InputBox( _
           "Please enter a value to search for. " & _
           "Enter a zero to indicate finished entry", _
           "Enter Search value")

    If IsNumeric(LSearchString) Then
        LSearchValue = CInt(LSearchString)
        If LSearchValue = 0 Then Exit Do

        iHowMany = iHowMany + 1
        If iHowMany > 15 Then
            MsgBox "You are limited to 15 search numbers.", vbOKOnly, "Limit reached"
            iHowMany = 15
            Exit Do
        End If
        aSearch(iHowMany) = LSearchValue
    End If
Loop

如果你想处理一个Cancel，使用一个中间Variant

Sub dural()
    Dim v As Variant, LSearchValue As Long
    v = InputBox("Please enter a value to search for. Enter a zero to indicate finished" & "entry.", "Enter Search value")
    If v = "" Then
        MsgBox "I guess you don't want to search"
    Else
        LSearchValue = CLng(v)
        MsgBox "I will search for " & LSearchValue
    End If
End Sub
