关于rc文件中的DDX_Control()和CONTROL [英] About DDX_Control() and CONTROL in rc file

问题描述

部分代码如下:

Part of the code is as below:

IDD_CONNECTOBJECT_DIALOG DIALOGEX 0, 0, 280, 142
STYLE DS_MODALFRAME | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
EXSTYLE WS_EX_APPWINDOW
CAPTION "ConnectObject"
FONT 8, "MS Sans Serif"
BEGIN
    CONTROL         "",IDC_OPCDATACTRL2,   //IDC_OPCDATACTRL1
                    "{FECBB6D0-6378-4B3E-A0EC-DCB28655BB55}",WS_TABSTOP,131,
                    112,17,17
    EDITTEXT        IDC_EDIT1,95,54,81,16,ES_AUTOHSCROLL | NOT WS_TABSTOP,
                    WS_EX_RIGHT
    PUSHBUTTON      "Disconnect",IDC_BUTTON1,151,84,61,22
    PUSHBUTTON      "ConnectObject",IDC_BUTTON2,68,84,71,21
    LTEXT           "This example uses the ConnectObject method to setup a subscription read and get the data back in the ValueChanged() event of the OPC data control and then update the text box below.  This is all done programmatically in the code in this example. ",
                    IDC_STATIC,7,7,258,38
END

void CConnectObjectDlg::DoDataExchange(CDataExchange* pDX)
{
    CDialog::DoDataExchange(pDX);
    //{{AFX_DATA_MAP(CConnectObjectDlg)
    DDX_Control(pDX, IDC_EDIT1, m_EditControl);
    DDX_Control(pDX, IDC_OPCDATACTRL2 , m_OPCDataControl);
    //}}AFX_DATA_MAP
}

-------------------------------------------------- --------------------------

任何人都可以在两部分中友好地解释一下IDC_OPCDATACTRL2的含义，以及在rc文件中编写的第一部分中CONTROL部分的含义吗?

----------------------------------------------------------------------------

Can anyone kindly explain what is the meaning of IDC_OPCDATACTRL2 in both parts and also what is the meaning of the CONTROL part in the first part written in rc file?

Thanks ahead!
