窗体创建的过程

因为网站的事情忙碌了一段时间，然后继续打算研究怎么读取～～～结果～～那些子模块还是没有读取成功…………

回个头来研究一下MFC～～～

窗体的创建过程如下：

1、设计窗体类：WNDCLASS

2、注册这个类：RegisterClass(&wndcls);

3、通过这个类创建窗体句柄：

eg: hwnd=CreateWindow( "sunxin2006", //所使用的窗体类
"http://www.sunxin.org", //窗体标题
WS_OVERLAPPEDWINDOW, //样式
0, //x
0, //y
600, //宽
400, //高
NULL, //父窗体句柄
NULL, //菜单句柄
hInstance, //包含窗体的实例句柄
NULL //附加参数
);

4、显示窗体：ShowWindow

5、刷新窗体：UpdateWindow

6、最后循环一下消息

7、回调函数：一般也就是用来处理消息函数的部分…………


#include <windows.h>


#include <iostream>




//定义回调函数


LRESULT CALLBACK WinSunProc(


HWND hwnd,


UINT uMsg,


WPARAM wParam,


LPARAM lParam


);




//主函数


int WINAPI WinMain(


HINSTANCE hInstance,


HINSTANCE hPrevInstance,


LPSTR lpCmdLine,


int nCmdShow


)




...{


//设计一个窗口类


WNDCLASS wndcls;


wndcls.cbClsExtra = 0;


wndcls.cbWndExtra = 0;


wndcls.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);


wndcls.hCursor = LoadCursor(NULL,IDC_CROSS);


wndcls.hIcon = LoadIcon(NULL,IDI_ERROR);


wndcls.hInstance = hInstance;


wndcls.lpfnWndProc = WinSunProc;


wndcls.lpszClassName = "mywindows";


wndcls.lpszMenuName = NULL;


wndcls.style = CS_HREDRAW|CS_VREDRAW;


RegisterClass(&wndcls);




//创建窗口，定义一个变量用来保存成功创建窗口后返回的句柄


HWND hwnd;


hwnd = CreateWindow("mywindows","我的窗口",WS_OVERLAPPEDWINDOW,0,0,600,400,NULL,NULL,hInstance,NULL);






//显示及刷新窗口


ShowWindow(hwnd,SW_SHOWNORMAL);


UpdateWindow(hwnd);




MSG msg;


while(GetMessage(&msg,NULL,0,0))




...{


TranslateMessage(&msg);


DispatchMessage(&msg);


}


return msg.wParam;


}




LRESULT CALLBACK WinSunProc(


HWND hwnd,


UINT uMsg,


WPARAM wParam,


LPARAM lParam


)




...{


switch(uMsg)




...{


case WM_CHAR:


char szChar[20];


sprintf(szChar,"Char Code is %C",wParam);


MessageBox(hwnd,szChar,"Char",0);


break;


case WM_CLOSE:


if(IDYES == MessageBox(hwnd,"是否关闭窗口？","结束",MB_YESNO))




...{


DestroyWindow(hwnd);


}


case WM_DESTROY:


PostQuitMessage(0);


break;


default:


return DefWindowProc(hwnd,uMsg,wParam,lParam);


}


return 0;


}
