Hot Key

)在VC ＋＋6.0 和VS2005中，大多数的窗口消息可以从ClassWizard 中找到，但是一些不常用的消息

在ClassWizard 中并没有封装,WM_HOTKEY 就是其中一个，因此用户必须手动添加。添加代码如下：

afx_msg LRESULT OnHotKey(WPARAM wp,LPARAM lp);

ON_MESSAGE(WM_HOTKEY,&CVS_2005_DlgDlg::OnHotKey)

LRESULT CVS_2005_DlgDlg::OnHotKey(WPARAM wp,LPARAM lp)

{

WinExec("notepad",1);//打开记事本

return 1;

}

2)注册热键

BOOL CVS_2005_DlgDlg::OnInitDialog()

{

...

UINT fsModifiers = 0;

fsModifiers |= MOD_CONTROL;

fsModifiers |= MOD_ALT;

RegisterHotKey(GetSafeHwnd(), 1, fsModifiers, VK_F8); // 注册热键

...

}

这样，每当按下Ctrl+Alt+F8时，就会调出Windows记事本程序。

hot key control用法:

A "hot key control" is a window that enables the user to create a hot key.

A "hot key" is a key combination that the user can press to perform an action quickly.

(For example, a user can create a hot key that activates a given window and brings it

to the top of the Z order.) The hot key control displays the user's choices and ensures

that the user selects a valid key combination.

1)加入控件变量：

CHotKeyCtrl m_hotKeyCtrl;

DDX_Control(pDX, IDC_HOTKEY1, m_hotKeyCtrl);

2)添加一按钮和按钮处理程序，用户设置完HotKey后按此按钮即设置了新的HotKey afx_msg void OnBnClickedButton2();

ON_BN_CLICKED(IDC_BUTTON2, &CVS_2005_DlgDlg::OnBnClickedButton2) void CVS_2005_DlgDlg::OnBnClickedButton2()

{

//#define HOTKEYF_SHIFT 0x01

//#define HOTKEYF_CONTROL 0x02

//#define HOTKEYF_ALT 0x04

//#define HOTKEYF_EXT 0x08

WORD VirtualKeyCode=0,fsModifiers = 0;

m_hotKeyCtrl.GetHotKey(VirtualKeyCode,fsModifiers);

//#define MOD_ALT 0x0001

//#define MOD_CONTROL 0x0002

//#define MOD_SHIFT 0x0004

//#define MOD_WIN 0x0008

//GetHotKey() 与RegisterHotKey()用的标志位不一样，需要转换

UINT fsModifiers2 = 0;

if (fsModifiers & HOTKEYF_SHIFT)

{

fsModifiers2 |=MOD_SHIFT;

}

if (fsModifiers & HOTKEYF_CONTROL)

{

fsModifiers2 |=MOD_CONTROL;

}

if (fsModifiers & HOTKEYF_ALT)

{

fsModifiers2 |=MOD_ALT;

}

RegisterHotKey(GetSafeHwnd(), 1, fsModifiers2, VirtualKeyCode); // 注册热键}
