[英]Redirection of a std::list<CString> content to a text file
I am using that code to enumerate files with specific extensions in a drive and write them out to a text file.我正在使用该代码来枚举驱动器中具有特定扩展名的文件并将它们写入文本文件。 It outputs something like this in the text file.
它在文本文件中输出类似这样的内容。 How can I write file address with their names instead of these garbage values .
我怎样才能用他们的名字而不是这些垃圾值来写文件地址。 00000281BBACF338 00000281BBACEA78 00000281BBACF108 00000281BBAD1E48

void FindFiles(
const CString& strRootPath,

CString strFileToFind = strRootPath;
ATLPath::Append(CStrBuf(strFileToFind, MAX_PATH), _T("*.*"));
WIN32_FIND_DATA findData = { 0 };
HANDLE hFileFind = ::FindFirstFile(strFileToFind, &findData);
if (INVALID_HANDLE_VALUE != hFileFind)
{
do
{
CString strFileName = findData.cFileName;
if ((strFileName == _T(".")) || (strFileName == _T("..")))
continue;
CString strFilePath = strRootPath;
ATLPath::Append(CStrBuf(strFilePath, MAX_PATH), strFileName);
if (bRecursive && (ATLPath::IsDirectory(strFilePath)))
{
FindFiles(strFilePath, strExt, listFiles);
}
else
{
CString strFoundExt = ATLPath::FindExtension(strFilePath);
if (!strExt.CompareNoCase(strFoundExt))
listFiles.push_back(strFilePath);
}
} while (::FindNextFile(hFileFind, &findData));
::FindClose(hFileFind);
}
}
int main()
{
std::ofstream file;
file.open("test.txt", std::ios::out | std::ios::app | std::ios::binary);
std::list<CString> listFiles;
FindFiles(_T("D:\\"), _T(".txt"), listFiles);
for (const auto& strFile : listFiles)
file << (LPCTSTR)strFile.GetString() << std::endl;
return 0;
}
You cast strfile
to LPCTSTR
, and write the file stream of ofstream
, the character sets of the two do not match.您将
strfile
为LPCTSTR
,并写入ofstream
的文件 stream ,两者的字符集不匹配。
You can use wofstream
to solve this problem:你可以使用
wofstream
来解决这个问题:
std::wofstream file;
Or use CT2A
function to convert it:或者使用
CT2A
function 进行转换:
for (const auto& strFile : listFiles)
file << CT2A(strFile) << std::endl;
