用VBA 4位小数格式化文本框

您是否可以将文本框格式设置为始终有四位小数？我知道如何使用C和VisualBasic使用屏蔽文本框来实现这一点，但由于缺少函数，vba更具挑战性。任何帮助都将不胜感激。谢谢

Public Sub UserForm_Initialize()
TextBox6.Text = Format(Number, "###.####")
End Sub

只是格式字符串不正确。应该是这样的：

Public Sub UserForm_Initialize()
    TextBox6.Text = Format(Number, "0.0000")
End Sub

尝试：

Public Sub UserForm_Initialize()
     TextBox6.Text = Format(Number, "0.0000")
End Sub

Private Sub TextBox6_Exit(ByVal Cancel As MSForms.ReturnBoolean)
    If IsNumeric(TextBox6.Value) Then
        TextBox6.Text = Format(TextBox6, "0.0000")
    End If
End Sub

Private Sub TextBox6_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
    '// Disregard keys other than 0-9/period/minus sign.
    If Shift Then KeyCode = 0
    Select Case KeyCode
    Case 8, 13, 46, 48 To 57, 96 To 105, 109, 110, 189, 190
    Case Else
        KeyCode = 0
    End Select
End Sub
