Answer 1

判断文件是否存在
BOOL CFileObjectMgr::IsPathFileExists(LPCTSTR lpPathFile)
{
if (lpPathFile == NULL)
{
return FALSE;
} if (0 == _tcslen(lpPathFile))
{
return FALSE;
} TCHAR tcsFileName[MAX_PATH + 1] = {0x00};
memset(tcsFileName, 0x00, sizeof(tcsFileName));
_tcsncpy(tcsFileName, lpPathFile, min(MAX_PATH, _tcslen(lpPathFile)));
if (tcsFileName[_tcslen(tcsFileName) - 1] == _T('\\'))
{
memset(tcsFileName, 0x00, sizeof(tcsFileName));
_tcsncpy(tcsFileName, lpPathFile, min(MAX_PATH, _tcslen(lpPathFile) - 1));
_tcscat(tcsFileName, _T("\0"));
} WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE; hFind = ::FindFirstFile(tcsFileName, &FindFileData);
if (hFind == INVALID_HANDLE_VALUE)
{
return FALSE;
} ::FindClose(hFind); return TRUE;
}
