VC下判断文件是否存在之最简方法

[kzh]

要判断D:/a.txt文件是否存在，最简单的方法是什么？
无论是MFC，还是SDK都行！

#include <io.h>
#include <stdio.h>
#include <stdlib.h>

void main( void )
{
/* Check for existence */
if( (_access( "D:\\a.txt", 0 )) != -1 )
{
printf( "File ACCESS.C exists\n" );
/* Check for write permission */
if( (_access( "ACCESS.C", 2 )) != -1 )
printf( "File ACCESS.C has write permission\n" );
}
}

if (INVALID_HANDLE_VALUE != CreateFile("D:\\a.txt", GENERIC_READ, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL))
{
AfxMessageBox("File ACCESS.C exists\n");
}

#define _WIN32_WINNT 0x0400

#include <windows.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;

printf ("Target file is %s.\n", argv[1]);
hFind = FindFirstFile(argv[1], &FindFileData);
if (hFind == INVALID_HANDLE_VALUE)
{
printf ("Invalid File Handle. GetLastError reports %d\n", GetLastError ());
return (0);
}
else
{
printf ("The first file found is %s\n", FindFileData.cFileName);
FindClose(hFind);
return (1);
}
}

if (GetFileAttributes("c:\\1.txt") == -1)
MessageBox(0."Invalid File ","hehe",0)
else
MessageBox(0."The first file found ","haha",0)
