在窗体上画一个命令按钮Command1，编写事件代码如下： Public x As Integer Private Sub Command1_Click() x=3 Call f1 Call f2 MsgBox x End Sub Private Sub f1() x=x*x End Sub Private Sub f2() Dim x As Integer x=x+4 End Sub 运行窗体后，单击命令按钮，则消息框的输出结果为______。

在窗体中添加一个命令按钮(名为Command1)，然后编写如下代码： Public x as integer Private Sub Command1_Click( ) x=5 Call s1 Call s2 MsgBox x End Sub Private Sub s1( ) x=x+10 End Sub Private Sub s2( ) Dim x as integer x=x+10 End Sub 窗体打开运行后，单击命令按钮，则消息框的输出结果是______

如下程序的运行结果是【1】. Private Sub Command1_Click() Dim x As Integer x = 12 f2 x Print x End Sub Public Sub f2(n As Integer) n = n Mod 10 End Sub

运行下面的程序，第二行显示结果是___________。 Private Sub Form_Click() Dim A As Integer Dim i As Integer A = 5 For i = 1 To 9 Call sub1(i, A) Print i, A Next i End Sub Private Sub sub1(x As Integer, y As Integer) Static N As Integer Dim I As Integer For I = 3 To 1 Step -1 N = N + x x = x + 2 Next I y = y + N End Sub

执行下列程序后，鼠标单击窗体，输出结果为( )。 Private Sub Form_Click() Print "Click"; End Sub Private Sub Form_MouseDown(Button As Integer, Shift A: As Integer,X As Single,Y As Single) B: Print "Down" C: End Sub D: Private Sub Form_MouseUp(Button As Integer, Shift_As Integer,X As Single,Y As Single) E: Print "Up" F: End SubA) DownUpClick G: B) ClickDownUp H: C) DownClickUp I: D) UpDownClick
