调用方法很简单，在Form中如下书写代码：
Private Sub Form_Load()
SetHotkey 1, "Ctrl,112", "Add" '按 Ctrl+F1 激活指定程序，F1的Ascii码为112
SetHotkey 2, 113, "Add" '按 F2 激活指定程序，F2的Ascii码为113
SetHotkey 3, "Ctrl+Alt,113", "Add" '按 Ctrl+Alt+F2 激活指定程序，F2的Ascii码为113
End Sub
Private Sub Form_Unload(Cancel As Integer)
SetHotkey 1, "", "Del" '退出程序是一定要用上的，不然会导至程序死掉
SetHotkey 2, "", "Del"
SetHotkey 3, "", "Del"
End Sub
在项目中新建一个模块(bas文件)，然后代码如下（此模块中需要我们修改的是Function keyWndproc()，这里的代码实现的是当系统中按了热键后的调用代码）：
Option Explicit
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As Long, ByVal id As Long, ByVal fskey_Modifiers As Long, ByVal vk As Long) As Long
Private Declare Function UnregisterHotKey Lib "user32" (ByVal hwnd As Long, ByVal id As Long) As Long
Const WM_HOTKEY = &H312
Const MOD_ALT = &H1
Const MOD_CONTROL = &H2
Const MOD_SHIFT = &H4
Const GWL_WNDPROC = (-4) '窗口函数的地址
Dim key_preWinProc As Long '用来保存窗口信息
Dim key_Modifiers As Long, key_uVirtKey As Long, key_idHotKey As Long
Dim key_IsWinAddress As Boolean '是否取得窗口信息的判断
Function keyWndproc(ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
If Msg = WM_HOTKEY Then
Select Case wParam 'wParam 值就是 key_idHotKey
Case 1 '激活 3 个热键后,3 个热键所对应的操作,大家在其他的程序中，只要修改此处就可以了
如今OCX控件在编程中已占领了很重要的地位,我们可以利用OCX控件完成一些相当复杂的编程操作.同时OCX 控件还有利于主程序的简单化、功能的重用、隐常程序实现细节、便于升级、传播方便等优点。现在我们可以利用VB 5.0方便的制作出自己的OCX控件供我们在编程中使用同时还可以把它送给你周围喜欢编程的朋友!

有时，为了实现动态更新，我们需要对正处于运行状态的应用程序进行自删除，就像360安全卫士在线升级那样。但是，Windows是不允许删除正处于运行状态的应用程序的，怎么办？一般来说，我们可以使用两个程序来实现，一个专门负责版本检测和删除，一个才是业务需要的主应用程序。能不能将二者合二为一呢？� ......
