Win32编程---在窗体添加一个按钮

//1.找到回调函数WindProcedure,有些书是WndProc  //2.定义一个HWND hwndButton    //3.在switch(Msg)下的case WM_CREATE:  添加如下代码   hwndButton=CreateWindow(TEXT("button"),//必须为：button  TEXT("anniu"),//按钮上显示的字符  WS_CHILD | WS_VISIBLE,0,0,20,20,hWnd,(HMENU)0,((LPCREATESTRUCT)lParam)->hInstance,NULL);//4.运行就可以了/*备注：下面是CreateWindow()函数的参数                                                                                                  HWND CreateWindow(   LPCTSTR lpClassName,   LPCTSTR lpWindowName,   DWORD dwStyle,   int x,   int y,   int nWidth,   int nHeight,   HWND hWndParent,   HMENU hMenu,   HANDLE hInstance,   PVOID lpParam ); */
