本次教程:这个在powerpoint里,完全和powerpoint结合起来,我简单写了
一下,新建一个vb程序,在窗体上放一个label,一个timer和一个按钮,timer的interval设置为1,Enable设置为False。
源码(不解释,自己研究):
Dim a(0 To 9) As String Private Sub Command1_Click()
Timer1.Enabled = Not Timer1.Enabled End Sub
Private Sub Form_Load()
SetHotkey Me.hwnd, 1, 0, vbKeyHome, \ a(0) = \张三\ a(1) = \李四\ a(2) = \王五\ a(3) = \刘六\ a(4) = \牛七\ a(5) = \马八\ a(6) = \杨九\ a(7) = \苟十\ a(8) = \朱十一\
a(9) = \吕十二\ End Sub
Private Sub Form_Unload(Cancel As Integer) SetHotkey Me.hwnd, 1, 0, 0, \ End Sub
Private Sub Timer1_Timer() Dim i As Integer i = Int(Rnd * 10) Label1.Caption = a(i) Label1.Tag = i End Sub
新建一个模块,写入以下代码
Private Declare Function SetWindowLong Lib \As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function GetWindowLong Lib \As Long, ByVal nIndex As Long) As Long
Private Declare Function CallWindowProc Lib \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 \ByVal fskey_Modifiers As Long, ByVal vk As Long) As Long
Private Declare Function UnregisterHotKey Lib \Long) As Long
Public Declare Function ShowWindow Lib \As Long) As Long
Public Declare Sub keybd_event Lib \dwFlags As Long, ByVal dwExtraInfo As Long)
Public Declare Function SendMessage Lib \Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Declare Function SetForegroundWindow Lib \
Const SW_HIDE = 0 Const SW_SHOW = 5 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 FormIsShowing As Boolean
Dim key_preWinProc As Long '用来保存窗口信息
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 多 个热键后,多 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
