请问有什么办法可以获取文件的最后修改日期和时间，vc，c++的都可以，急！！！！！

运行系统为win2000!请大虾不吝赐教！！！！

FindFirstFile
FindNextFile
就可以了

[Kevin_qing]

BOOL GetFileAttributesEx(
LPCTSTR lpFileName, // file or directory name
GET_FILEEX_INFO_LEVELS fInfoLevelId, // attribute
LPVOID lpFileInformation // attribute information
);


的fInfoLevelId参数里面

[flounder]

GetFileAttributesEx()

[jaidy]

BOOL GetFileAttributesEx(
LPCTSTR lpFileName, // file or directory name
GET_FILEEX_INFO_LEVELS fInfoLevelId, // attribute class
LPVOID lpFileInformation // attribute information
);
fInfoLevelId
[in] Specifies the class of attribute information to retrieve. This parameter can be one of the following values.
Value Meaning
GetFileExInfoStandard The lpFileInformation parameter is a
WIN32_FILE_ATTRIBUTE_DATA structure
建议仔细看看msdn

用“CFile::GetStatus（LPCTSTR lpszFileName, CFileStatus& rStatus );
”

rStatus

A reference to a user-supplied CFileStatus structure that will receive the status information. The CFileStatus structure has the following fields:

CTime m_ctime The date and time the file was created.


CTime m_mtime The date and time the file was last modified.


CTime m_atime The date and time the file was last accessed for reading.


LONG m_size The logical size of the file in bytes, as reported by the DIR command.


BYTE m_attribute The attribute byte of the file.


char m_szFullName[_MAX_PATH] The absolute filename in the Windows character set.


Example:

CFileStatus status;
extern CFile cfile;
if( cfile.GetStatus( status ) ) // virtual member function
{
#ifdef _DEBUG
afxDump << "File size = " << status.m_size << "\n";
#endif
}
char* pFileName = "test.dat";
if( CFile::GetStatus( pFileName, status ) ) // static function
{
#ifdef _DEBUG
afxDump << "Full file name = " << status.m_szFullName << "\n";
#endif
}

one more powerful shell api

ShGetFileInfo

[xintiaf]

HANDLE hFile;
FILEATTRIB attrib;
WIN32_FIND_DATA WFD;
SYSTEMTIME systime;
FILETIME localtime;
har stime[32]; //输出时间

if((hFile=FindFirstFile(attrib.filename,&WFD))=INVALID_HANDLE_VALUE)
return false;//失败
//ok,转换时间
FileTimeToLocalFileTime(&WFD.ftLastWriteTime,&localtime);
FileTimeToSystemTime(&localtime,&systime);
sprintf(stime,"%4d-%02d-%02d %02d:%02d:%02d",
systime.wYear,systime.wMonth,systime.wDay,systime.wHour,
systime.wMinute,systime.wSecond);
AfxMessageBox(stime);

[xintiaf]

先将你要找的文件名（包括全路径）给attrib.filename

[xintiaf]

刚刚写错了：）
这个调试通过！

void CTestDlg::OnBtnTest()
{
HANDLE hFile;
WIN32_FIND_DATA wfd;
SYSTEMTIME systime;
FILETIME localtime;
char stime[32]; //输出时间
memset(&wfd, 0, sizeof(wfd));

if((hFile=FindFirstFile("F:\\VC\\MFC\\Test\\Release\\Test.exe", &wfd))==INVALID_HANDLE_VALUE)
{
char c[2];
DWORD dw=GetLastError();
wsprintf(c, "%d", dw);
AfxMessageBox(c);
return ;//失败
}
//ok,转换时间
FileTimeToLocalFileTime(&wfd.ftLastWriteTime,&localtime);
FileTimeToSystemTime(&localtime,&systime);
sprintf(stime,"%4d-%02d-%02d %02d:%02d:%02d",
systime.wYear,systime.wMonth,systime.wDay,systime.wHour,
systime.wMinute,systime.wSecond);
AfxMessageBox(stime);
}

可是为什么我用 CreateFile后，再用 GetFileTime就不行呢，
code：
HANDLE hFile;
hFile= CreateFile("C:\\Documents and Settings\\tsl\\桌面\联系.txt",GENERIC_READ,FILE_SHARE_WRITE,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
BOOL bFile=GetFileTime(hFile,lpCreationTime,lpLastAccessTime,lpLastWriteTime) ;
其实问题已经解决了，只是想知道的说！

十分多谢日月紫光详细解答，还有我心迷茫，雨一直下。。。。。
分明天给，各大虾可否再指点一二！！！
麻烦大家了！

BOOL GetFileInformationByHandle(
[in]HANDLE hFile, // handle to file
[out]LPBY_HANDLE_FILE_INFORMATION lpFileInformation // buffer
);

typedef struct _BY_HANDLE_FILE_INFORMATION {
DWORD dwFileAttributes;
FILETIME ftCreationTime;
FILETIME ftLastAccessTime;

DWORD dwVolumeSerialNumber;
DWORD nFileSizeHigh;
DWORD nFileSizeLow;
DWORD nNumberOfLinks;
DWORD nFileIndexHigh;
DWORD nFileIndexLow;
} BY_HANDLE_FILE_INFORMATION, *PBY_HANDLE_FILE_INFORMATION;

1.ftCreationTime
Specifies the time the file was created. If the underlying file system does not support this time member, ftCreationTime is zero.
2.ftLastAccessTime
Specifies the time the file was last accessed. If the underlying file system does not support this time member, ftLastAccessTime is zero.
3.ftLastWriteTime
Specifies the last time the file was written to.
