模式对话框的一个按钮中能不能调用CWinApp类的OnFileNew函数，如何调用？

[wftttt]

我想实现的功能是 在多文档视图程序中，点击主窗口“新建”菜单，然后弹出一个对话框，在对话框的几个编辑框中设置参数后，点击“确定”按钮，在子框架窗口中创建一张表并显示，但是我在对话框的按钮处理函数中不知道如何调用CWinApp类的OnFileNew函数，或者说不知道能不能调用，所以感觉没办法继续下去了，请大神们指导！

OnFileNew没有任何实际意义，只是框架预留的接口 调用是可以的，但是调用它干嘛呢， 相关功能还是要你自己实现

仅供参考： WM_COMMAND The WM_COMMAND message is sent when the user selects a command item from a menu, when a control sends a notification message to its parent window, or when an accelerator keystroke is translated. WM_COMMAND wNotifyCode = HIWORD(wParam); // notification code wID = LOWORD(wParam); // item, control, or accelerator identifier hwndCtl = (HWND) lParam; // handle of control Parameters wNotifyCode Value of the high-order word of wParam. Specifies the notification code if the message is from a control. If the message is from an accelerator, this parameter is 1. If the message is from a menu, this parameter is 0. wID Value of the low-order word of wParam. Specifies the identifier of the menu item, control, or accelerator. hwndCtl Value of lParam. Handle to the control sending the message if the message is from a control. Otherwise, this parameter is NULL. Return Values If an application processes this message, it should return zero. Remarks Accelerator keystrokes that select items from the window menu are translated into WM_SYSCOMMAND messages. If an accelerator keystroke occurs that corresponds to a menu item when the window that owns the menu is minimized, no WM_COMMAND message is sent. However, if an accelerator keystroke occurs that does not match any of the items in the window's menu or in the window menu, a WM_COMMAND message is sent, even if the window is minimized. If an application enables a menu separator, the system sends a WM_COMMAND message with the low-word of the wParam parameter set to zero when the user selects the separator. QuickInfo Windows NT: Requires version 3.1 or later. Windows: Requires Windows 95 or later. Windows CE: Requires version 1.0 or later. Header: Declared in winuser.h.

主要是我搞不清楚OnFileNew的工作过程，这个相关功能我不知道怎么实现，不知道具体步骤，所以才想着调用这个接口函数，求指导
