享受做同一件事的人

Private Sub cmdAdd_Click()
    'add to apartment
    CurrentDb.Execute " INSERT INTO Apartment(Apartment, Account_ID, Total_area, Heated_area, People) " & _

           Me.txtTotal_area & "','" & Me.txtHeated_area & "','" & Me.txtPeople & "')"
    'add to owner
    CurrentDb.Execute " INSERT INTO Owner (Account, FName, LName, MName) " & _
           " VALUES ( " & Me.txtAcc & ",'" & Me.txtFName & "','" & _
           Me.txtLName & "','" & Me.txtMName & "')"
    'clear
    cmdClear_Click

您可以设置边框的背景：

<Grid Background="White">
    <Border Background="Red" BorderBrush="White" BorderThickness="2" CornerRadius="50,50,0,0">
    </Border>
</Grid>
