MFC registers the hotkey for the dialog box and the hotkey for the mfc dialog box.

MFC registers the hotkey for the dialog box and the hotkey for the mfc dialog box.
 

Add the following content to the header file:

//} AFX_MSG
Afx_msg LRESULT OnHotKey (WPARAM wParam, LPARAM lParam); // (this behavior is added)
BEGIN_MESSAGE_MAP (DlgYesNo, CDialog)
// {AFX_MSG_MAP (DlgYesNo)

Add the following to the cpp file:
//} AFX_MSG_MAP

ON_MESSAGE (WM_HOTKEY, OnHotKey) // (this behavior is added)
END_MESSAGE_MAP ()

 

You can also add the WM_HOTKEY message method in the "Class Wizard" to generate the preceding steps.

 

Add the following content to the OnCreat event: (add message response> WM_CREAT)
RegisterHotKey (m_hWnd, 1001, MOD_ALT, 'q ');

Add: (add message response> WM_DESTROY) to the OnDestroy event)
UnregisterHotKey (m_hwnd, 1001 );

Add the message processing function: (paste it in. Note that CHotkeyDlgDlg is changed to its own class)

LRESULT CHotkeyDlgDlg::OnHotKey(WPARAM wParam,LPARAM lParam){    if(wParam == 1001)    {       int nMod = LOWORD(lParam);       int Vk = HIWORD(lParam);       CString str;       str.Format(_T("Mod = %d, Vk = %d"), nMod, Vk);       AfxMessageBox(str);    }    return true;}
