Question

我有以下代码： Range("P" & Rows.Count).End(xlUp).offset(1).Value = InputBox("INTRODUCE ACT JUSTIFICATIV") 用户必须在输入框中输入字母

如果输入框中的值为空白且出现个性化错误消息，我想防止用户意外按下Enter键。

然后按“取消”按钮退出子菜单。

Answer 1

将“用户”输入设置为变量，然后进行测试以查看其是否有效。

Dim usrInput as String

Do
    usrInput = InputBox("INTRODUCE ACT JUSTIFICATIV")

    If usrInput = vbNullString Then
        MsgBox "Your Error Message"
    End If
Loop While usrInput = vbNullString

Answer 2

请尝试下一种方法：

Sub testInputBoxValidate()
  Dim strInpB As String
  strInpB = InputBox("INTRODUCE ACT JUSTIFICATIV")
  If strInpB = "" Then MsgBox "You did not introduce anything!": Exit Sub
  Range("P" & Rows.count).End(xlUp).Offset(1).Value = strInpB
End Sub

还有一种强制用户输入内容的变体：

Sub testInputBoxValidate()
  Dim strInpB As String
Start:
  strInpB = InputBox("INTRODUCE ACT JUSTIFICATIV")
  If strInpB = "" Then MsgBox "You did not introduce anything!": GoTo Start
  Range("P" & Rows.count).End(xlUp).Offset(1).Value = strInpB
End Sub

我还建议您尝试其他检查。例如，“ ACT JUSTIFICATIV”必须没有特定的长度（数字位数）吗？像“ xxxx ###”这样的特定模式，其中“ ###”是三（x）位数字？

Answer 3

您可以使用Application.InputBox来给您更多的控制权。将提示用户，直到他们输入非空白字符串或按“取消”或“ x”按钮

Dim vInput As Variant: vInput = ""
Do
    vInput = Application.InputBox("INTRODUCE ACT JUSTIFICATIV", Type:=2) '2 -> String type
    If vInput = False Then 'User pressed Cancel or x button
        Exit Do
    ElseIf Len(vInput) > 0 Then 'User has entered non-blank value
        Range("P" & Rows.Count).End(xlUp).Offset(1).Value = vInput
        Exit Do
    End If
Loop

Answer 4

我认为您仅在输入内容后才能强制InputBox关闭。取而代之的是，将结果读入变量并循环直到输入有效的值

Dim answer as string, okay As Boolean
answer = ""
okay = False
Do While Not okay
    answer = InputBox("INTRODUCE ACT JUSTIFICATIV")
    On Error Resume Next
    okay = Range(answer & "1").Address <> ""
    On Error GoTo 0
Loop

现在，输入框将弹出，直到输入有效列为止。

输入框可防止用户在值空白时按Enter键
