CString StrClsName = AfxRegisterWndClass(

CS_VREDRAW | CS_HREDRAW,

LoadCursor(NULL, IDC_CROSS),

(HBRUSH)GetStockObject(BLACK_BRUSH),

LoadIcon(NULL, IDI_WARNING));

First->Create(StrClsName, NULL, WS_CHILD, );

}

void CSecondDlg::OnSecondControl()

{

// TODO: Add your control notification handler code here

CWnd *Second = new CWnd;

Second->Create(NULL, NULL, WS_CHILD, );

}

void CSecondDlg::OnThirdControl()

{

// TODO: Add your control notification handler code here

CWnd *Memo = new CWnd;

Memo->Create("EDIT", "Voice Recorder", WS_CHILD, );

}

void CSecondDlg::OnFourthControl()

{

// TODO: Add your control notification handler code here

CStatic *Label = new CStatic;

Label->Create("United Nations", WS_CHILD, );

}

The WS_CHILD style is defined in the Win32 library as:

#define WS_CHILD 0x40000000L

11.4.2..Visibility................................................................................................

If you want to display a control to the user when the parent window comes up, at design

time, set the Visible property to True. If you are programmatically creating the control,

add the WS_VISIBLE style. Here is an example:

void CSecondDlg::OnSecondControl()

{

// TODO: Add your control notification handler code here

CWnd *Second = new CWnd;

Second->Create(NULL, NULL, WS_CHILD | WS_VISIBLE, );

}

The visibility style is defined as:

#define WS_VISIBLE 0x10000000L

The child style combined with the visibility style produces:
