11.4.3 Availability

By default, after a control has been created, it is available to the user. If it is a non-static

control, the user can possibly select or change its value. If you do not want the control to

be immediately usable but do not want to hide it, you can disable it. To do this, if you are

designing the control, you can set its Disable property to True or checked. If you are

programmatically creating the control, add the WS_DISABLED style as follows:

void CSecondDlg::OnSecondControl()

{

// TODO: Add your control notification handler code here

CWnd *Second = new CWnd;

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

}

The disabled style is defined as follows:

#define WS_DISABLED 0x08000000L

The above combination would produce:
