Edit Control的Enter响应函数

Edit Control的Enter响应函数

1.   在dialog中添加edit control ，选择“Multi_Line mode”
2.   MFC Class Wizard中添加Virtual Function ，将PreTranslateMessage函数重载，并在重载函数中添加如下代码
3. 一个例子如下：

 

if ( WM_KEYFIRST == WM_KEYDOWN ) // <= pMsg->message && pMsg->message <= WM_KEYLAST
    if (pMsg->wParam==VK_RETURN )
    {
        HWND hWnd=::GetFocus();
        int   m_nID=::GetDlgCtrlID(hWnd);
        GX_STATUS status;
        if ( m_nID == 1023IDC_EDIT_ExplosureTime )  
        {

            UpdateData(TRUE);

            if (m_bLfDeviceOpen)

        status = m_LfCamera.SetFloat( GX_FLOAT_EXPOSURE_TIME, m_fExplosureTime);

            if (m_bLfDeviceOpen)

        status = m_RiCamera.SetFloat( GX_FLOAT_EXPOSURE_TIME, m_fExplosureTime);

            m_sldShutter.SetPos(( int )m_fExplosureTime );

            UpdateData(FALSE);  
        }
    }

return CDialog::PreTranslateMessage(pMsg);
