Remarks

Call this member function to modify a window’s extended style. Styles to be added or removed can be combined by using the bitwise OR (|) operator. See the topics Extended Window Styles in this book and::CreateWindowEx in the Win32 SDK Programmer’s Reference for information about the available extended styles

• SWP_NOSIZERetains the current size.
• SWP_NOMOVERetains the current position.
• SWP_NOZORDERRetains the current Z order.
• SWP_NOACTIVATEDoes not activate the window.
