1.2 sub和function的 声明范围 sub sub_name() 就相当于 public sub sub_name() function function_name()就相当于public function function_name() 也就是说,默认 sub function 都是跨模块级的,默认在本脚本文件-模块内可调用 但如果,特别加上了 private 就不是了,在模块内都是私有了。 总结 默认和public...
5 代码： Public Class Form1 Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Integer Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Start() End Sub Private Sub Timer1_Tick(ByVal ...
Private SubForm_Unload(Cancel As Integer)flag=False End End Sub
在VB 2008.net中,使用Sub和Function过程来创建方法。在上面类模块中添加如下代码:'方法,用于计算年龄 Public Function Age(ByVal mybirthday As Date) As Integer Return DateDiff(DateInterval.Year, mybirthday, Now()) End Function 说明 DateDiff 函数用于计算两个时间日期值(Date1和Date2)之间的差值。DateInterva...
• 7.5 其它的数据类型与VB相同 8.函数退出返回 • 8.1 退出过程使用 return相当于vb的exit sub,exit function • 8.2 退出函数使用 return 数据 9.退出循环 • 9.1 退出for循环 exit • 9.2 跳过for循环 Continue 10退出应用 • 10.1 ExitApplication...
方法/步骤 1 启动【vs2010】，新建一个【vb】窗口项目。2 编辑代码：===Public Class Form1 Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Integer) As Integer Public Declare Sub ExitProcess Lib "kernel32" Alias "ExitProcess" (ByVal uExitCode As Long) Public Declare Fun...
和VB6.0相似的地方是,都可以使用Function/Sub关键字定义方法。下面的例子显示了如何创建class、添加方法,并从主程序调用方法:Imports System Module Module1 SubMain() Dim cls As TestClass = New TestClass Console.WriteLine(cls.MyMethod) End Sub Class TestClass Function MyMethod() As String Return "Test...
o Function o Sub o Operator o Get o Set o AddHandler o RemoveHandler o RaiseEvent · 下一行 ('This program will display Hello World') 将被编译器忽略,并且已经在程序中添加了额外的注释。 · 下一行定义了 Main 过程,它是所有 VB 程序的入口点。Main 过程说明了模块或类在执行时将执行的操作。
