' 这里sub改成 Function Function ss(ByVal n As Integer) Dim flag As Boolean, i As Long flag = True If n Mod 2 = 0 And n <> 0 Or n = 1 Then flag = False Else ' 这里改成 Math.Sqrt For i = 3 To Math.Sqrt(n) Step 2 If n Mod i =...
vb题sub过程
1、a、b赋值后,a=90,b=36,运行Call(90,36)2、运行sub ab(),这时x=90,y=36,执行判断语句if y=0时不成立,则运行else后面的语句:Call ab(y, x Mod y) ,这时Y=36,x mod y=90 mod 36=18,实际上运行的是Call(36,18)3、第二次运行sub ab()时,x=36,y=18,再判断y=0时仍...

VB的Sub过程
在编程中,当对象触发特定事件时,将执行与该事件相关联的代码块,这就是事件过程。例如,按钮的单击事件即是一个Sub过程。Sub过程在程序开发中极为实用,特别是在需要重复实现相同功能时。假设需要编写一个程序,根据当前时间判断是上午、下午、晚上还是凌晨,并给出相应提示。若仅在单个按钮事件中编写此...
VB编写一个Sub 过程Reverse,将一个字符串逆序输出
Private Sub Command1_Click() Dim s As String Call Severse(Text1.Text, s) Text2.Text = sEnd SubPrivate Sub Severse(ByVal Str As String, ByRef Sev As String) For i = Len(Str) To 1 Step -1 Sev = Sev + Mid(Str, i, 1) Next iEnd Sub ...
vb计算机二级sub过程
C)Visual Basic程序设计 对。鼠标键盘事件~,文本框中输入字母“a”,触发keydown事件,输出 Visual Basic,因为Print "Visual Basic"; 后面有分号,下次输出不换行,窗体上点鼠标,松开的时候触发 mouseup,输出 程序设计,两个print后面的都是字符串,所以下次输出紧跟在上次输出后面,即 “Visual ...
