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
今天做一个VB程序的自显注册码。我也不知道该怎么叫，就是找到出现注册码的地方，然后用对话框弹出来。说白了就是用MessageBox把一个字符串给弹出来（没追求阿。。。）
为了有点追求，今天不导入user32里面的API，而是把VB里面自带的Msgbox函数给挖出来调用，就是引用MSVBVM60.rtcMsgBox函数。我� ......
简单而实用的合并Excel文件的函数，能够将多个XLS文件中指定数量的工作表自动合并到一个XLS文件里。当然，如果只是数据合并，则使用ADO就可以实现，但如果要保留表格格式，则恐怕只能使用俺的方法了。
一、函数代码：
