c++ - fwprintf is printing out garbage -


I have a program that receives a list of directories (selected by the user) and list the related directories and files While printing the file in that directory, it is always a '?' Then prints a random character after that. I am working on WinAPi, Visual C ++ 2010 Express I am using Unicode (hence I am using extensive characters). I am guessing my problem that it is in the phf printf function that I am using because it adds the directory / files in my std :: list which is right to me. This is my current task: 

  list for std :: list & lt; Std :: wstring & gt; LDirectories; Zero Cleanup Contents (Constwchar_t * sDir) {List Directory Content (SDIR) // function that adds each file and directory to the std :: list wchar_t dir [MAX_PATH * 10]; Wsprintf (DIR, L "% s \\ listoff files and directories.t.tt.", SDIR); FILE * pFile; Errno_t err = _wfopen_s (and Pfile, DIR, L "W"); While (! LDirectories.empty ()) {fwprintf (Pfile, L "% s", lDirectories.front ()); LDirectories.pop_front (); } Err = fclose (pFile); }

The problem is in this line: 

  FF print (Pfile, L "% s", lDirectories.front ());

fwprintf is expected to be wchar_t * and you provide wstring . Change to

: 

  fwprintf (pFile, l "% s", lDirectories.front () .c_str ());

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
