VC下简易实现全局热键–无DLL无钩子(Register HotKey)
使用RegisterHotKey()函数即可.
MSDN:The RegisterHotKey function defines a system-wide hot key.

1 2 3 4 5 6 7 |
//函数原型: BOOL RegisterHotKey( HWND hWnd, // window to receive hot-key notification int id, // identifier of hot key UINT fsModifiers, // key-modifier flags UINT vk // virtual-key code ); |
具体实现:
1.首先加入函数
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
BOOL CMyDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here //注册热键(Ctrl+W,标识9999) RegisterHotKey(this->m_hWnd,9999,MOD_CONTROL,'W'); return TRUE; // return TRUE unless you set the focus to a control } |
2.加入相应全局热键函数

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
//相应WindowProc消息,加入函数 LRESULT CMyCatchScreenDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) { switch(message) { /////////////// //热键操作 case WM_HOTKEY: if(wParam==9999) { if(!IsWindowVisible()) { //ShowMyWindow(); // 实现代码 } else { //HideMyWindow(); //实现代码 } } break; } return CDialog::WindowProc(message, wParam, lParam); } |
