我想實作的功能是 在多檔案視圖程式中，點擊主視窗“新建”選單，然后彈出一個對話框，在對話框的幾個編輯框中設定引數后，點擊“確定”按鈕，在子框架視窗中創建一張表并顯示，但是我在對話框的按鈕處理函式中不知道如何呼叫CWinApp類的OnFileNew函式，或者說不知道能不能呼叫，所以感覺沒辦法繼續下去了，請大神們指導！

OnFileNew沒有任何實際意義，只是框架預留的介面呼叫是可以的，但是呼叫它干嘛呢，
相關功能還是要你自己實作

僅供參考：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.

主要是我搞不清楚OnFileNew的作業程序，這個相關功能我不知道怎么實作，不知道具體步驟，所以才想著呼叫這個介面函式，求指導
