如何判断一个文件是否存在?

[joiny2000]

如何判断一个文件(TXT)是否存在? 我是用CFile 的open?
请告诉我如何用它?

CFile f;
if (!f.Open("test.txt", CFile::modeRead))
{
cout << "file does not exist" << end;
}

[Stephen_Ma]

virtual BOOL Open( LPCTSTR lpszFileName, UINT nOpenFlags, CFileException* pError = NULL );

Return Value

Nonzero if the open was successful; otherwise 0. The pError parameter is meaningful only if 0 is returned.


CFile sourceFile;
CFileException ex;
if (!sourceFile.Open("MyFile.TXT", CFile::modeRead, &ex))
{
AfxMessageBox("Can not open file");
return ;
}

bool FileExist(const char *pszFileName )
{
WIN32_FIND_DATA WFD;
HANDLE hFind = ::FindFirstFile(pszFileName, &WFD);
if (hFind == INVALID_HANDLE_VALUE)
{
return false;
}
::FindClose(hFind);
return true;
}

BOOL IsFileCreated(CString PathName)
{
CFileStatus Status;
if(CFile::GetStatus(PathName,Status))
return TRUE;
return FALSE;
}

[opentuxedo]

BOOL IsFileExisted(CString PathName)
{
CFileStatus Status;
if(CFile::GetStatus(PathName,Status))
return TRUE;
return FALSE;
}
