子窗口的創建非常非常重要

步驟：1、新建窗口類，在窗口類中指名對應的自定義的窗口過程。窗口類類名要唯一，它?????

?????????是各窗口類相互區別的標識。注意，類名或為靜態變量，或為全局變量，因為程

?????????序隨時都用他們。

??????2、創建窗體時，指定其風格之一為WS_CHILD,?指定其父窗口句柄，得到父窗體實

?????????例句柄，并賦給子窗體。

??????3、在主窗體的create消息中，創建0尺寸的子窗體，主窗體的size消息中，利用

????????movewindow函數，重設窗體大小，重置窗體位置。

實例為CTRL002,CTRL003

實例CTRL001單擊按鈕顯示對應文字

子窗口向父窗口發送消息

CreateWindow呼叫使用下面這些參數：

Class?name（類別名稱） Window?text（窗口文字） Window?style（窗口樣式） x?position（x位置） y?position（y位置） Width（寬度） Height（高度） Parent?window（父窗口） Child?window?ID（子窗口ID） Instance?handle（執行實體句柄 ）Extra?parameters（附加參數）

TEXT?("button") button[i].szText WS_CHILD|WS_VISIBLE|button[i].iStyle cxChar cyChar?*?(1?+?2?*?i) 20?*?xChar 7?*?cyChar?/?4 hwnd (HMENU)i ((LPCREATESTRUCT)?lParam)?->?hInstance NULL

?

?

說明：從WM_COMMAND區別出單擊了哪個按鈕。通過子窗口的ID號來區分。每個子窗口在創建時，就已經分配了一個唯一的ID號。ID號包含在WM_COMMAND消息中wParam的低字節位。用LOWORD()宏來獲取ID。

??????“用鼠標單擊按鈕時，子窗口控制就向其父窗口發送一個WM_COMMAND消息。...捕獲WM_COMMAND消息....”

???????“LOWORD(wParam)???子窗口ID

?????????HIWORD(wParam)????通知碼

?????????lParam??????????????子窗口句柄”

實例CTRL002?利用多個靜態窗體繪制棋盤

說明：1、窗體類別必需是static類，否則程序不能生成靜態窗體

??????2、利用GetWindowLong得到窗體實例句柄

??????3、HWND是數值類型，可以定義成數組

??????4、創建子窗體時，將大小設為0,以便重置

??????4、利用movewidow(...)函數重置靜態子窗體位置
