如何利用VB实现按下一个按钮等同按下键盘上CTRL和enter键

如何利用VB实现按下一个按钮等同按下键盘上CTRL和enter键
如何利用VB实现按下一个按钮等同按下键盘上shift和右键
当在键盘上按下CTRL和enter键时它的作用和按这个按一样

这个问题我老搞不懂，代码谢谢
我想做到按下键盘上CTRL和enter键可以让窗体全屏显示
呵呵，希望不要用timer控件
二楼说得那么抽象，能否详细一点，如果是我要的答案，给你再加30分吧

Answer 1

你说不要要timer控件，那我给你全局热键代码：
添加一个模块
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, 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.WindowState = 0
Form1.SetFocus
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

在窗体里加入代码：
Private Sub Form_Load()
Dim ret As Long

preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)

ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf Wndproc)

idHotKey = 1
Modifiers = MOD_CONTROL 'Ctrl 键
uVirtKey = vbKeyReturn 'enter键
ret = RegisterHotKey(Me.hwnd, idHotKey, Modifiers, uVirtKey)

End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim ret As Long
'取消Message的截取，使之送往原来的windows程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)
Call UnregisterHotKey(Me.hwnd, uVirtKey)
End Sub

注册热键，如果注册系统热键，窗口不是当前也有效。
