对话框中的Visual C++数据不显示

我是C++的新手，我正在使用MFC。我有一个对话框，当您连接相机时，它会显示相机的信息。
这是该对话框的资源代码
IDD_PVSIMPLEUISAMPLE DIALOGEX 0, 0, 575, 284
STYLE DS_SETFONT | DS_FIXEDSYS | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME
EXSTYLE WS_EX_APPWINDOW

PUSHBUTTON "Display",IDC_DISPLAYPOS,205,17,355,254,NOT WS_VISIBLE | WS_DISABLED
GROUPBOX "Acquisition Control",IDC_CONTROL_GROUP2,4,128,187,77
END然后，我创建了一个新的对话框，当您单击设置按钮时将打开该对话框。我复制了几行代码到新对话框中，但是从摄像头传输的实际数据没有显示出来。
以下是设置对话框的代码
IDD_SETTINGS DIALOGEX 0, 0, 444, 319
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "Settings"
FONT 8, "MS Shell Dlg", 400, 0, 0x1
BEGIN
DEFPUSHBUTTON "OK",IDOK,205,298,50,14
LTEXT "IP address",IDC_STATIC,10,41,45,8
EDITTEXT IDC_IP_EDIT,65,37,119,14,ES_AUTOHSCROLL | ES_READONLY | WS_DISABLED
LTEXT "MAC address",IDC_STATIC,10,58,50,8
EDITTEXT IDC_MAC_EDIT,65,55,119,14,ES_AUTOHSCROLL | ES_READONLY | WS_DISABLED
LTEXT "Manufacturer",IDC_STATIC,10,75,50,8
EDITTEXT IDC_MANUFACTURER_EDIT,65,72,119,14,ES_AUTOHSCROLL | ES_READONLY | WS_DISABLED
LTEXT "Model",IDC_STATIC,10,93,44,8
EDITTEXT IDC_MODEL_EDIT,65,90,119,14,ES_AUTOHSCROLL | ES_READONLY | WS_DISABLED
LTEXT "Name",IDC_STATIC,10,110,44,8
EDITTEXT IDC_NAME_EDIT,65,107,119,14,ES_AUTOHSCROLL | ES_READONLY | WS_DISABLED
END如何使数据显示在对话框中？我需要为它创建一个完整的类吗？任何帮助/建议都将受到重视。

在第一个对话框中，您可以声明第二个对话框的类对象，使用该对象获取item控件对象，然后设置数据。所以你可以这样做，在设置按钮的回调函数中，添加以下代码：
CAAADialog::OnXXXButton()
{
CBBBDialog dlgb;
dlgb.DoModal();
dlgb.GetDlgItem(IDC_IP_EDIT)->SetWindowText(m_strIp);
dlgb.GetDlgItem(IDC_MAC_EDIT)->SetWindowText(m_strMac);
dlgb.GetDlgItem(IDC_MANUFACTURER_EDIT)->SetWindowText(m_strManufacture);
dlgb.GetDlgItem(IDC_NAME_EDIT)->SetWindowText(m_strName);
