多.cpp文件出错：error LNK2005: _main already defined in winmain.obj

东莞某某某 2010-10-13 11:15:15

Main.c文件如下：

#include <windows.h>



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

TCHAR szAppName[] = TEXT("NotePad");





int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nShowCmd)

{

	WNDCLASS wndclass;

	HWND hwnd;

	MSG msg;



	wndclass.style  = CS_HREDRAW | CS_VREDRAW ;

	wndclass.lpfnWndProc  = WndProc ;

	wndclass.cbClsExtra  = 0 ;

	wndclass.cbWndExtra  = 0 ;

	wndclass.hInstance  = hInstance ;

	wndclass.hIcon  = LoadIcon (hInstance, szAppName) ;

	wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;

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

	wndclass.lpszMenuName  = szAppName ;

	wndclass.lpszClassName = szAppName ;



	if (!RegisterClass (&wndclass))

   	{

  		MessageBox(NULL,TEXT ("请更新你的系统！"),szAppName, MB_ICONERROR) ;

        return 0 ;

  	}

	

	

	hwnd = CreateWindow(szAppName, szAppName,

        WS_OVERLAPPEDWINDOW,

        GetSystemMetrics (SM_CXSCREEN) / 4,

        GetSystemMetrics (SM_CYSCREEN) / 4,

        GetSystemMetrics (SM_CXSCREEN) / 2,

        GetSystemMetrics (SM_CYSCREEN) / 2,

        NULL, NULL, hInstance, NULL) ;



	ShowWindow (hwnd, nShowCmd) ;

	UpdateWindow (hwnd) ;

	

	

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

   	{

		TranslateMessage (&msg) ;

		DispatchMessage (&msg) ;

	}

	

	return msg.wParam ;

}



LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)

{

	switch(message)

	{

	case WM_CREATE:



		return 0;



	case WM_SIZE:



		return 0;



	case WM_SETFOCUS:



		return 0;



	case WM_CLOSE:

		DestroyWindow(hwnd);

		return 0;



	case WM_DESTROY:

		PostQuitMessage(0);

		return 0;



	}



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

}

请问如何将Main.c分割为两个文件？
分割为如下两个文件链接会出错：error LNK2005: _main already defined in winmain.obj



//WinMain.c
