一般使用API函數生成SDK窗體的順序是這樣的
首先包含<windows.h>
再定義一個Win32窗體程序的消息處理函數
如:LRESULT CALLBACK WinSunProc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam)
在int WINAPI WinMain()主函數中
1.設計窗體類
定義一個WIN32的窗體類結構 WNDCLASSEXA并填充數據
2.注冊窗體類
將設計好的WIN32窗體結構類進行注冊
可以使用RegisterClassExA函數
3.創建窗體獲取窗體句柄
使用CreatWindow函數創建窗體 并返回窗體的句柄
4.更新窗體
創建一個消息循環截獲相關消息GetMessage
并把消息推送給窗體TranslateMessage()DispatchMessage()
接下來就是消息處理函數的認為了
可以使用默認 DefWindowProc()處理

生產窗體可以使用CreateWindowEx函數。
函數功能:該函數創建一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函數創建一個層疊的,自動彈出的(pop-up)或是一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。要獲得更多的關于創建窗口的信息和關于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, //指向注冊類名的指針
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
);例程:
