生產窗體可以使用CreateWindowEx函數。
函數功能：該函數創建壹個具有擴展風格的層疊式窗口、彈出式窗口或子窗口，其他與CreateWindow函數相同。
函數原型：
CreateWindowEx函數創建壹個層疊的，自動彈出的（pop－up）或是壹個子窗口通過擴展格式。另外這個函數的作用與CreateWindow函數的作用相同。要獲得更多的關於創建窗口的信息和關於CreateWindowEx函數參數的詳細描述。參見CreateWindow
HWND CreateWindowEx(
DWOR DdwExStyle, //窗口的擴展風格
LPCTSTR lpClassName, //指向註冊類名的指針
LPCTSTR lpWindowName,? //指向窗口名稱的指針
DWORD dwStyle,? //窗口風格
int x,? //窗口的水平位置
int y,? //窗口的垂直位置
int nWidth, //窗口的寬度
int nHeight, //窗口的高度
HWND hWndParent, //父窗口的句柄
HMENU hMenu, //菜單的句柄或是子窗口的標識符
HINSTANCE hInstance, //應用程序實例的句柄
LPVOID lpParam? //指向窗口的創建數據
