假定有以下函数过程:Function Fun(s As String) As String Dim s1 As String For i = 1 To Len(s) s1 = UCase(Mid(s, i, 1)) + s1 Next i Fun = s1End Function在窗体上添加一个命令按钮,然后编写如下事件过程:Private Sub Command1_Click() Dim Str1 As String Dim Str2 As String Str1 = InputBox(“请输入一个字符
假定有以下函数过程:Function Fun(s As String) As String Dim s1 As String For i = 1 To Len(s) s1 = UCase(Mid(s, i, 1)) + s1 Next i Fun = s1End Function在窗体上添加一个命令按钮,然后编写如下事件过程:Private Sub Command1_Click() Dim Str1 As String Dim Str2 As String Str1 = InputBox(“请输入一个字符串”) Str2 = Fun(Str1) Print Str2End Sub程序运行后,单击命令按钮,如果在输入对话框中输入字符串“abcdefg”,则单击“确定”按钮后再窗体上输出的结果为()。

- 上一篇:假定有如下的Sub过程:Sub fun(x As Single, y As Single) t = x x = t / y y = t Mod yEnd Sub在窗体上画一个命令按钮,然后编写如下事件过程:Private Sub Command1_Click() Dim a As Single Dim b As Single a = 6 b = 4 fun a, b Print a, bEnd Sub程序运行后,单击命令按钮,输出结果为()。
- 下一篇:有如下函数过程:Function secproc(x As Integer, y As Integer, z As Integer) secproc = 3 y + z + 2 xEnd Function Private Sub Command1_Click() Dim a As Integer, b As Integer, c As Integer a = 2: b = 3: c = 4 Print secproc(c, b, a)End Sub该程序的运行结果是()。
