分享请问WM_MDIMAXIMIZE 和SC_MAXIMIZE的区别
请问SendMessage(hwndClient, WM_MDIMAXIMIZE, childHwnd, 0);和SendMessage(childHwnd, WM_SYSCOMMAND, SC_MAXIMIZE, 0);有什么本质区别吗？后者可以代替前者吗？
比如说我知道子窗口的窗口句柄，那么我可以直接发送WM_SYSCOMMAND, SC_MAXIMIZE去最大化它，这两种做法有什么区别吗？

WM_MDIMAXIMIZE :
An application sends the WM_MDIMAXIMIZE message to a multiple-document interface (MDI) client window to maximize an MDI child window.
WM_SYSCOMMAND
A window receives this message when the user chooses a command from the Window menu (formerly known as the system or control menu) or when the user chooses the maximize button, minimize button, restore button, or close button.
