Specifies the common dialog box hook procedure that is overridden to add specific functionality to a common dialog box.
[Visual Basic] Overrides Protected Function HookProc( _ ByVal hWnd As Integer, _ ByVal msg As Integer, _ ByVal wParam As Integer, _ ByVal lParam As Integer _ ) As Integer [C#] protected override int HookProc( int hWnd, int msg, int wParam, int lParam ); [C++] protected: override int HookProc( int hWnd, int msg, int wParam, int lParam ); [JScript] protected override function HookProc( hWnd : int, msg : int, wParam : int, lParam : int ) : int;
A zero value if the default dialog box procedure processes the message; A nonzero value if the default dialog box procedure ignores the message.
Raising an event invokes the event-handling method through a delegate. For an overview, see TBD.
Notes to Inheritors: When overriding HookProc in a derived class, be sure to call the base class's HookProc method.
