VB 全局快捷键问题

我只想要一个键作为我要使用的快捷键(如空格键SPACE),不需要辅助键ALT或CTRL之类，应该如何改？

小弟分不多，麻烦大虾们帮帮忙。谢了！

如下代码，

'以下程序放在模块中
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_CONTROL = &H2
Public Const MOD_SHIFT = &H4
Public Const GWL_WNDPROC = (-4)

Public preWinProc As Long
Public Modifiers As Long, uVirtKey1 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
Dim lp As taLong, i2 As t2Int

If Msg = WM_HOTKEY Then
If wParam = idHotKey Then
lp.ll = lParam
LSet i2 = lp
If (i2.lWord = Modifiers) And i2.hword = uVirtKey1 Then
'------------------------------------------------------
'这里面是快捷键代码，你可以随便改

If Form1.Check100.value = 1 Then
Form1.Check100.value = 0
Else
Form1.Check100.value = 1
End If

'------------------------------------------------------
End If
End If
End If
'如果不是热键信息则调用原来的程序
wndproc = CallWindowProc(preWinProc, hwnd, Msg, wParam, lParam)
End Function

'窗体中
Option Explicit

Private Sub Form_Load()
Dim ret As Long
'记录原来的window程序地址
preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
'用自定义程序代替原来的window程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf wndproc)
idHotKey = 1 'in the range ＆h0000 through ＆hBFFF
Modifiers = MOD_ALT '辅助键为Alt
uVirtKey1 = vbKey1 '注册的热键为Alt+1
'注册热键
ret = RegisterHotKey(Me.hwnd, idHotKey, Modifiers, uVirtKey1)
If ret = 0 Then
MsgBox "注册热键失败,请使用其它热键!", vbCritical, "错误"
End If
End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
Dim ret As Long
'取消Message的截取，使之送往原来的window程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)
Call UnregisterHotKey(Me.hwnd, uVirtKey1)
End Sub
谢谢1楼的朋友，但用GetAsyncKeyState配合TIMER计时不够精确，我是想在我上面找的代码的基础上，能不能修改成不要辅助键，只要按一个键(如SPACE键)就行 2楼的方法果然天才，不过不方便不同机器使用啊。

其实很简单的 ~~~~只要不注册辅助键就可以了~~修改了~~

Answer 2

设一个timer,定时调用GetAsyncKeyState函数,返回值非0说明该键被按下

声明:
Private Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState" (ByVal vKey As Long) As Integer

类似:
private sub timer1_timer()
if GetAsyncKeyState(vbKeyReturn) then
msgbox"Enter key pressed."
' do some work ...
end if
end sub

掉用WINDOWS的注册表 改键盘上的键子的注册表信息 这方法天才不
微软的安装程序输入字符用的就是键盘的注册信息
