Hi,   Here is the code snippet I am using under windows in VS2008.   #define BOOST_WINDOWS_PATH #define BOOST_WINDOWS_API

You shouldn't be manually defining these, and would normally get a compile error...

#include "stdafx.h"

but you probably are configure to use precompiled headers, so anything before stdafx.h is ignored.

#include <boost/filesystem/operations.hpp> #include <boost/filesystem/fstream.hpp> #include <iostream> #include "string" #include "conio.h" #include "vector"   using namespace std; using namespace boost::filesystem;     int _tmain(int argc, _TCHAR* argv[]) { string _path = "E:\\doggy"; path dir_path(_path.c_str()); vector< pair<string,bool> > _file_jpeg_pair; string full_list_path = _path+"\\" + "list.txt"; string bundle_path_str = _path+"\\" + "bundle"; path bundle_path(_path.c_str()); //creating bundle directory cout<<bundle_path<<endl; //if( !exists( bundle_path ) ) create_directory(bundle_path); cout<<"directory created "<<endl; getch(); return 0; }    This code is giving run time unhandled exception, so for that matter any other call of boost filesystem.

Catch the unhandled exception and see what the problem is. Filesystem throws boost::system::system_error exceptions.

Strange thing is the Windows path E:\doggy is being printed as E:/doggy, seems like the path is getting converted to POSIX format.

Depending on the boost filesystem version you can ask for native formatted strings. Jeff _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Hi Ian, escape character is not the problem. I would put my code here: #include "stdafx.h"#include "Windows.h"#include <boost/filesystem/operations.hpp>#include <boost/filesystem/fstream.hpp>#include <iostream>#include "string"#include "conio.h"#include "vector"#include <boost/exception/diagnostic_information.hpp> #define BOOST_WINDOWS_PATH #define BOOST_WINDOWS_APIusing namespace std;using namespace boost::filesystem;  extern "C" void straight_to_debugger(unsigned int, EXCEPTION_POINTERS*){    throw;}extern "C" void (*old_translator)(unsigned, EXCEPTION_POINTERS*)         = _set_se_translator(straight_to_debugger); int _tmain(int argc, _TCHAR* argv[]){ string _path = "E:\\doggy"; path dir_path(_path.c_str());    vector< pair<string,bool> > _file_jpeg_pair;      string full_list_path = _path+"\\" + "list.txt";    string bundle_path_str = _path+"\\" + "bundle";    path bundle_path(_path.c_str());    //creating bundle directory  cout<<bundle_path<<endl;   //boost::system::system_error exceptions;  //if( !exists( bundle_path ) )  try{   create_directory(bundle_path);  }  catch(boost::system::system_error const &e)  {   cerr<<diagnostic_information(e)<<endl;  }  cout<<"directory created "<<endl;   getch(); return 0;} You can see that, I have used proper path. The problem is the Windows style path is getting converted somehow in POSIX format. As I printed the path and it came out to be E:/doggy Can you point me what mistake I am doing here.

Is the directory name being specified in the C++ source code? If so then remember that "\" is used for character escape sequences. If you are specifying the name in the source code, you may need to type "E:\\doggy". The double "\" will resolve to a single "\" in the executable.

Hi Jeff,

Thanks for the reply.

I caught the exception using this code:

try{ create_directory(bundle_path); } catch(boost::system::system_error const &e) { cerr<<diagnostic_information(e)<<endl; }

The printed output was

Throw in function (unknown) Dynamic exception type: class boost::exception_detail::clone_impl<struct boost:: exception_detail::error_info_injector<class boost::filesystem::basic_filesystem_ error<class boost::filesystem::basic_path<class std::basic_string<char,struct st d::char_traits<char>,class std::allocator<char> >,struct boost::filesystem::path _traits> > > > std::exception::what: boost::filesystem::create_directory: The filename, directo ry name, or volume label syntax is incorrect: "E:\doggy"

Can you point me what mistake I am doing here?..I believe the syntax of path is correct.

Please don't top post. Lookup the documentation on create_directory versus create_directories. Simplify your test case to just what's needed for creating your directories. Jeff
