Frederic, Thanks for the reply. 1. That's interesting. I omitted to mention I'm using Boost 1.33 so I'll try with a later version. 2. Yes, you're right - same happens with supplying backslashes. 3. MS Visual Studio .NET 2003. I'll investigate the macro you mention. Regards, Pete frederic.bron@alcan.com wrote: 1. works fine on my windows platform. 2. Strange that you say that C:/autoexec.bat is native. I would say C:\autoexec.bat is but this is not where you get the error. 3. What is your compiler? With some, you need to compile with macro BOOST_WINDOWS_API. F. Bron boost-users-bounces@lists.boost.org a écrit sur 16/07/2008 08:40:35 :
Hello,
I want to use the Boost.Filesystem library in my Win32 application. I've stumbled upon a problem which may very well be my misunderstanding of how to use the library but reading the documentation doesn't clear up my confusion.
The user choses a path from a native UI and a bfs::path is constructed with the native name checker. This path needs to be persisted so I call the string() method which according to the documentation "Returns: The contents of m_name, formatted according to the rules of the generic path string grammar." I figured this string would be acceptable to the bfs::path constructor without specifying native because it's in the corrct grammar but I get an exception thrown. Here's a stripped down version of my code:
#include #include #include namespace bfs = boost::filesystem; int main() { try { // Path constructed from a native UI so constructed with native bfs::path myPath("C:/autoexec.bat",bfs::native); // Persist to grammar conformant string std::string persisted = myPath.string(); // Recreate from persisted string - *THROWS EXCEPTION* bfs::path otherPath(persisted); } catch(const std::exception& e) { std::cout << e.what() << std::endl; } return 0; }
The exception string is "boost::filesystem::path: invalid name "C:" in path: "C:/autoexec.bat""
Can someone explain how I should be doing this please?
Thanks,
Pete_______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
