限制只能输入中文

Private Sub TextBox1_KeyUp(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
strText = TextBox1.Text
Length = 0
For i = 1 To Len(strText)
    temp = Asc(Mid$(strText, i, 1)) '将每个字符转为ASCII码
    If temp > 255 Or temp < 0 Then ‘ASCII码小于0或大于255则为中文字
        TextBox1.Text = Left(strText, Length)
    Else
        Length = Length + 1
    End If
Next i
End Sub

限制只能输入数字

Private Sub TextBox4_Change()
If Len(TextBox4) > 0 And Not IsNumeric(TextBox4.Value) Then
   If Asc(TextBox4) <> 45 Then ’判断是否是负号
           TextBox4.SetFocus
            SendKeys "{BACKSPACE}"
   End If
End If
End Sub
