WM_NCCREATE

This message is sent prior to the WM_CREATE message when a window is first created.

Parameter

Description

wParam	Contains a handle to the window that is being created.
lParam	Points to the CREATESTRUCT data structure for the window.

Return Value

The return value is nonzero if the nonclient area is created. It is zero if an error occurs; the CreateWindow function will return NULL in this case.

Default Action

Scroll bars are initialized (the scroll-bar position and range are set) and the window text is set. Memory used internally to create and maintain the window is allocated.
