Suppose there is a CString variable which store the full path of the file.Now I hava to find only file name from if.How to do it in vc++.
CString FileName = "c:\Users\Acer\Desktop\FolderName\abc.dll"; Now I want only abc.dll.

- I recommend the function decomposePath described here.no one special– no one special2017-02-23 19:51:29 +00:00Commented Feb 23, 2017 at 19:51

You can use PathFindFileName.
Remember that you have to escape the \ character in your path string!

@Mark, Why to convert? If it is char* - ANSI build, pass char* !
Same as already stated above, but as u are using MFC framework, this would be the way to do it. Though this does not check files existence.
CString path= "c:\\Users\\Acer\\Desktop\\FolderName\\abc.dll"; CString fileName= path.Mid(path.ReverseFind('\\')+1);

BTW CString is not just for MFC - see <atlstr.h>. More at msdn.microsoft.com/en-us/library/ms174288.aspx
std::string str = "c:\\Users\\Acer\\Desktop\\FolderName\\abc.dll"; std::string res = str.substr( str.find_last_of("\\") + 1 ); Will get you "abs.dll".

Why use std::string when you have CString which has the required functions
I would use Boost::FileSystem for filename manipulation as it understands what the parts of a name would be. The function you want here would be filename()
If you are just getting the filename you can do this using CString functions. First find the ast backslash using ReverseFind and then Right to get the string wanted.

The code below demonstrate extracting a file name from a full path
#include <iostream> #include <cstdlib> #include <string> #include <algorithm> std::string get_file_name_from_full_path(const std::string& file_path) { std::string file_name; std::string::const_reverse_iterator it = std::find(file_path.rbegin(), file_path.rend(), '\\'); if (it != file_path.rend()) { file_name.assign(file_path.rbegin(), it); std::reverse(file_name.begin(), file_name.end()); return file_name; } else return file_name; } int main() { std::string file_path = "c:\\Users\\Acer\\Desktop\\FolderName\\abc.dll"; std::cout << get_file_name_from_full_path(file_path) << std::endl; return EXIT_SUCCESS; }
