一般使用API函数生成SDK窗体的顺序是这样的
首先包含<windows.h>
再定义一个Win32窗体程序的消息处理函数
如:LRESULT CALLBACK WinSunProc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam)
在int WINAPI WinMain()主函数中
1.设计窗体类
定义一个WIN32的窗体类结构 WNDCLASSEXA并填充数据
2.注册窗体类
将设计好的WIN32窗体结构类进行注册
可以使用RegisterClassExA函数
3.创建窗体获取窗体句柄
使用CreatWindow函数创建窗体 并返回窗体的句柄
4.更新窗体
创建一个消息循环截获相关消息GetMessage
并把消息推送给窗体TranslateMessage()DispatchMessage()
接下来就是消息处理函数的认为了
可以使用默认 DefWindowProc()处理

生产窗体可以使用CreateWindowEx函数。
函数功能:该函数创建一个具有扩展风格的层叠式窗口、弹出式窗口或子窗口,其他与CreateWindow函数相同。
函数原型:
CreateWindowEx函数创建一个层叠的,自动弹出的(pop-up)或是一个子窗口通过扩展格式。另外这个函数的作用与CreateWindow函数的作用相同。要获得更多的关于创建窗口的信息和关于CreateWindowEx函数参数的详细描述。参见CreateWindow
HWND CreateWindowEx(
DWOR DdwExStyle, //窗口的扩展风格
LPCTSTR lpClassName, //指向注册类名的指针
LPCTSTR lpWindowName, //指向窗口名称的指针
DWORD dwStyle, //窗口风格
int x, //窗口的水平位置
int y, //窗口的垂直位置
int nWidth, //窗口的宽度
int nHeight, //窗口的高度
HWND hWndParent, //父窗口的句柄
HMENU hMenu, //菜单的句柄或是子窗口的标识符
HINSTANCE hInstance, //应用程序实例的句柄
LPVOID lpParam //指向窗口的创建数据
);例程:
