子窗口的WM_CREATE的替代方法

Question

我用以下老技巧将子窗口子类化：

SetWindowLongPtr(hWnd, GWLP_WNDPROC, (LONG_PTR)&NewWndProc);

但WM_CREATE消息永远不会发送给它：

LRESULT CALLBACK NewWndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    HBRUSH hBackground;

    switch (msg)
    {
        case WM_CREATE:
        // this is never received in my child window
        break;
    }
}

另一种可以替代它的消息是什么，我可以在其中初始化我打算在HBRUSH或HBITMAP中使用的WM_PAINT，WM_NOTIFY / NM_CUSTOMDRAW变量？
