VB中如何为程序设置快捷键

用全局热键
运行后程序自动隐藏，按快捷键自动出现
'第一步:

'新建一个窗口,将以下代码复制进去 注册热键为:'Ctrl+Alt+P

Private Sub Form_Load()
form1.hide
Dim ret As Long
preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf Wndproc)
idHotKey = 1
Modifiers = MOD_Alt + MOD_Ctrl
uVirtKey = vbKeyP
ret = RegisterHotKey(Me.hwnd, idHotKey, Modifiers, uVirtKey)
End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim ret As Long
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)
Call UnregisterHotKey(Me.hwnd, uVirtKey)
End Sub

'第二步

'新建立一个模块,然后将以下内容复制到模块中
Option Explicit

Declare Function SetWindowLong Lib "User32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Declare Function GetWindowLong Lib "User32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
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
Declare Function RegisterHotKey Lib "User32" (ByVal hwnd As Long, ByVal id As Long, ByVal fsModifiers As Long, ByVal vk As Long) As Long
Declare Function UnregisterHotKey Lib "User32" (ByVal hwnd As Long, ByVal id As Long) As Long

Public Const WM_HOTKEY = &H312
Public Const MOD_Alt = &H1
Public Const MOD_Ctrl = &H2
Public Const MOD_Shift = &H4
Public Const GWL_WNDPROC = (-4)

Public preWinProc As Long
Public Modifiers As Long, uVirtKey As Long, idHotKey As Long

Private Type taLong
ll As Long
End Type

Private Type t2Int
lWord As Integer
hWord As Integer
End Type

Public Function Wndproc(ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
If Msg = WM_HOTKEY Then
If wParam = idHotKey Then
Dim lp As taLong, i2 As t2Int
lp.ll = lParam
LSet i2 = lp
If (i2.lWord = Modifiers) And i2.hWord = uVirtKey Then
form1.show
End If
End If
End If
Wndproc = CallWindowProc(preWinProc, hwnd, Msg, wParam, lParam)
End Function

在主窗体的菜单设置里设置就行了
