验证文本框输入

Question

我在Excel中创建了一个userform，并有一个数据验证范围。

我想在用户点击＆＃34;保存＆＃34;之前检查用户的输入。按钮。

例如：值输入为＆＃34; x＆＃34;，如果1 <= x <= 10，数据文本框将标记为红色突出显示并弹出消息＆＃34;失控＆＃34;，表单将请求用户继续输入＆＃34;重新测试＆＃34;数据范围内的文本框（在Excel文件中）。

由于您将x设置为文本框的值，因此您不需要在案例选择中使用if语句。

Select Case x
    Case 0.3
        MsgBox "Correct"
    Case Is < 0.3
        MsgBox "Lower limit"
    Case Is > 0.3
        MsgBox "Upper Limit"
End Select

请注意，我使用的限制不一定与您的限制相对应。

要验证文本框，您可以编写一个afterupdate sub，当您通过按Tab键取消选择文本框时会触发该子文件。它可能看起来像下面的子类，要知道要么为要检查的每个输入写一个子，如果你有很多类似的输入，你可以编写一个从afterupdate子调用的私有子。检查文本框的值是否为数字，并且位于某些参数内。

Private Sub txNgay_AfterUpdate()
    If Me.txNgay = Empty Then
        'Code which sets the the look of textbox back to normal.
    ElseIf Not IsNumeric(Me.txNgay) Then
        MsgBox "The textbox doesn't contain a numerical value.", vbCritical
        'Code which sets the look of the textbox to a faulty state
    ElseIf Me.txNgay < 1 Or Me.txNgay > 10 Then
        MsgBox "The value is out of range"
        'Code which sets the look of the textbox to a faulty state
    Else
        'Code which sets the look of the textbox to a normal state
    End If
End Sub

你甚至可以在模块中包含一个私有子，每次更新一个字段时会调用它来检查所有输入，只有在满足所有条件时才激活OK按钮。

您可以使用大小写选择来执行基于值的代码

Select Case x
    Case 0
        'Code to perform the actions you need if x is 0
    Case 1 To 10
        'Code to perform the actions you need if x is between 1 and 10
    Case Else
        'Code to perform the actions you need if x is < 0 and x > 10
End Select
