Prevent Enter and Esc close dialog program

Well there are also many way, such as Override the OnOK() and OnCancel().

The easier and more powerful way is to Overrides the function PreTranslateMessage() in the dialog class.

BOOL CServerSocketDlg::PreTranslateMessage(MSG* pMsg) {     if (pMsg->message == WM_KEYDOWN || nVirtKey == VK_RETURN) {          int nVirtKey = (int) pMsg->wParam;        if (nVirtKey == VK_ESCAPE)            return TRUE;     }         return CDialog::PreTranslateMessage(pMsg); }

 

But in this way all Enter key pressed event will be disabled, if wanna press Enter to click a button, we can add extra code:

// CButton m_ctlMessage        if (nVirtKey == VK_RETURN && (GetFocus()->m_hWnd  == m_ctlMessage.m_hWnd))        {            // this is the CButton function OnBnClickedButton1();            return TRUE;        }
