程序的代码。
基本都是按着视频打进去的。



#include <windows.h>

#include <stdio.h>







LRESULT CALLBACK Replace(

  HWND hwnd,      // handle to window

  UINT uMsg,      // message identifier

  WPARAM wParam,  // first message parameter

  LPARAM lParam   // second message parameter

);







int WINAPI WinMain(

  HINSTANCE hInstance,  // handle to current instance

  HINSTANCE hPrevInstance,  // handle to previous instance

  LPSTR lpCmdLine,      // pointer to command line

  int nCmdShow          // show state of window

)

{

	WNDCLASS wndclass;

	wndclass.cbClsExtra=0;

	wndclass.cbWndExtra=0;

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

	wndclass.hCursor=LoadCursor(NULL,IDC_CROSS);

	wndclass.hIcon=LoadIcon(NULL,IDI_APPLICATION);

	wndclass.hInstance=hInstance;

	wndclass.lpfnWndProc=Replace;

	wndclass.lpszClassName="wangchu";

	wndclass.lpszMenuName=NULL;

	wndclass.style=CS_HREDRAW||CS_VREDRAW;

	RegisterClass(&wndclass);







	HWND hwnd;

	hwnd=CreateWindow("wangchu","wangchu",WS_OVERLAPPEDWINDOW,100,100,400,600,NULL,NULL,hInstance,NULL);

	ShowWindow(hwnd,SW_SHOWNORMAL);

	UpdateWindow(hwnd);







	MSG msg;

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

	{

		TranslateMessage(&msg);

		DispatchMessage(&msg);

	}

	return 0;

}







LRESULT CALLBACK Replace(

  HWND hwnd,      // handle to window

  UINT uMsg,      // message identifier

  WPARAM wParam,  // first message parameter

  LPARAM lParam   // second message parameter

)

{

	switch(uMsg)

	{

	case WM_CHAR:

		char szChar[20];

		sprintf(szChar,"输入的字母是%S",wParam);

		MessageBox(hwnd,szChar,"YES?",MB_OK);

		break;

	case WM_LBUTTONDOWN:

		MessageBox(hwnd,"wangchu","YES?",MB_OK);

		HDC hdc1;

		hdc1=GetDC(hwnd);

		TextOut(hdc1,0,50,"wangchu",strlen("wangchu"));

		ReleaseDC(hwnd,hdc1);

		break;

	case WM_PAINT:

		HDC hdc2;

		PAINTSTRUCT ps;

		hdc2=BeginPaint(hwnd,&ps);

		TextOut(hdc2,0,100,"wangchu",strlen("wangchu"));

		EndPaint(hwnd,&ps);

		break;

	case WM_CLOSE:

		if(IDYES==MessageBox(hwnd,"YES?","wangchu",MB_YESNO))

		{

			DestroyWindow(hwnd);

		}

		break;

	case WM_DESTROY:

		PostQuitMessage(0);

		break;

	default:

		DefWindowProc(hwnd,uMsg,wParam,lParam);

	}

	return 0;

}

提示的错误是。
--------------------Configuration: WinMain - Win32 Debug--------------------
Compiling...
WinMain.cpp
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/WinMain.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

WinMain.exe - 2 error(s), 0 warning(s)

实在没看懂错误。
帮帮我这个刚入门就受挫的菜鸟吧。

工程错了
1.新建win32工程而不是控制台工程 .
2.修改工程设置
setting->link-> project options:
修改/subsystem:console为/subsystem:windows
或者直接删除/subsystem:windows

剩下一个错误啦。
Error executing link.exe
