Question

windows窗口C语言写的，给解释下。

#include <windows.h>

LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

char szClassName[ ] = "Week";

int WINAPI WinMain (HINSTANCE hThisInstance,HINSTANCE hPrevInstance,LPSTR lpszArgument,int nFunsterStil)
{
HWND hwnd; /* This is the handle for our window */
MSG messages; /* Here messages to the application are saved */
WNDCLASSEX wincl; /* Data structure for the windowclass */

/* The Window structure */
wincl.hInstance = hThisInstance;
wincl.lpszClassName = szClassName;
wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */
wincl.style = CS_DBLCLKS; /* Catch double-clicks */
wincl.cbSize = sizeof (WNDCLASSEX);

/* Use default icon and mouse-pointer */
wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
wincl.lpszMenuName = NULL; /* No menu */
wincl.cbClsExtra = 0; /* No extra bytes after the window class */
wincl.cbWndExtra = 0; /* structure or the window instance */
wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;
if (!RegisterClassEx (&wincl))
return 0;
hwnd = CreateWindowEx (
0, /* Extended possibilites for variation */
szClassName, /* Classname */
"Week", /* Title Text */
WS_OVERLAPPEDWINDOW, /* default window */
CW_USEDEFAULT, /* Windows decides the position */
CW_USEDEFAULT, /* where the window ends up on the screen */
600, /* The programs width */
500, /* and height in pixels */
HWND_DESKTOP, /* The window is a child-window to desktop */
NULL, /* No menu */
hThisInstance, /* Program Instance handler */
NULL /* No Window Creation data */
);
ShowWindow (hwnd, nFunsterStil);
while (GetMessage (&messages, NULL, 0, 0))
{
TranslateMessage(&messages);
DispatchMessage(&messages);
}
return messages.wParam;
}

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message) /* handle the messages */
{
case WM_DESTROY:
PostQuitMessage (0); /* send a WM_QUIT to the message queue */
break;
default: /* for messages that we don't deal with */
return DefWindowProc (hwnd, message, wParam, lParam);
}
return 0;
}
每一行代码的作用？ 我不懂英文噢！看不懂.
还有LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);这是个函数吧？怎么没有类型声明？这个函数又是做什么用的？
如果我要在这个窗口中加几个可以打开的菜单栏怎么加？
要在窗口上面显示几个文字之类的又怎么做？
有高手给解释下没？
不懂C的指针我发这个做什么！ 请看清楚我的问题然后一一解答！知道的给解释下，谢谢了！！！

不是有中文版的Win32 API教材吗。要搞懂Win32系统，首先要搞清楚C语言里面的函数指针，关于函数指针的调用。搞清楚来再看就很容易了。

这是创建WINDOWS 最基本的一些操作。基本上就是些什么创建HWND 消息，窗口 什么的，然后一个死循环用来捕获消息， 你写的
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);是一个回调函数 有CALLBACK 函数名 WindowProcedure 函数类型 LRESULT 至于中文翻译，去看WIN32 的API吧，
