BOOL SubclassDlgItem( UINT nID, CWnd* pParent );
Return Value
Nonzero if the function is successful; otherwise 0.
Parameters
nID
The control’s ID.
pParent
The control’s parent (usually a dialog box).
Remarks
Call this member function to “dynamically subclass” a control created from a dialog template and attach it to this CWnd object. When a control is dynamically subclassed, windows messages will route through the CWnd’s message map and call message handlers in the CWnd’s class first. Messages that are passed to the base class will be passed to the default message handler in the control.
This member function attaches the Windows control to a CWnd object and replaces the control’s WndProc and AfxWndProc functions. The function stores the old WndProc in the location returned by the GetSuperWndProcAddr member function.
