    Rename failed with file name had space, hyphen etc after unicode support.

    Hi,

    I intent to use this mechanism for rename the file because the file name consists Unicode characters
    I would like to know why the return value of "MoveFileExW" is false for file name consists 'space','hyphen' etc.(sometimes even without a Unicode character).for accepting 'space','hyphen' what type of conversion I would use [I.e.: Does the root cause of failure is due to CP_UTF8 type use]

    Please see the code

    Code:
       //! inputPath & final_inputPath consist source and destination file name and are std::string
       //! Both are in same directory F:\test_files\
       
       std::wstring unicode_input_original;
       int unicode_input_length_original = 0
       
       std::wstring unicode_input_final;
       int unicode_input_length_final = 0;
       
        unicode_input_length_original = MultiByteToWideChar(CP_UTF8,0,inputPath.data(),inputPath.length(),NULL,0);
        unicode_input_original.resize(unicode_input_length_original);
        MultiByteToWideChar(CP_UTF8,0,inputPath.data(),inputPath.length(),&unicode_input_original[0],unicode_input_original.length());
        const wchar_t *input_name_original = unicode_input_original.c_str();
    	
    	unicode_input_length_final = MultiByteToWideChar(CP_UTF8,0,final_inputPath.data(),final_inputPath.length(),NULL,0);
        unicode_input_final.resize(unicode_input_length_final);
        MultiByteToWideChar(CP_UTF8,0,final_inputPath.data(),final_inputPath.length(),&unicode_input_final[0],unicode_input_final.length());
        const wchar_t *input_name_final = unicode_input_final.c_str();
    	
    	bool ret = MoveFileExW(input_name_original,input_name_final,MOVEFILE_REPLACE_EXISTING);
    -Dave.

    Where is your call to GetLastError? That is what you should call immediately after calling MoveFileExW if it returns 0.

    Re: Rename failed with file name had space, hyphen etc after unicode support.

    Where does inputPath & final_inputPath come from and how do you know they are UTF8 encoded?

    Here's are some utility functions for doing the conversions: http://forums.codeguru.com/showthrea...31#post1790131

    You may want to change the return type to bool so that it's easy to detect conversion errors.

    You need a new keyboard. The one you have seems to be dropping letters.

    Once you get a keyboard that can type complete words, you may want to state what you'd like help with.
