So I have a program, I need to show with dynamic char cat all file in directory, but it is compilable in Borland C++ but in Visual Studio 15 + Resharper it doesn't work. Severity Code Description Project File Line Error (active) argument of type "char *" is incompatible with parameter of type "LPCWSTR"

To compile your code in Visual C++ you need to use Multi-Byte char WinAPI functions instead of Wide char ones.

Set Project -> Properties -> General -> Character Set option to Use Multi-Byte Character Set

    Or, stop using the TCHAR based APIs and use the char based APIs instead (FindFirstFileA() and WIN32_FIND_DATAA). Or stop using char everywhere and use wchar_t instead, and then use the wchar_t based APIs (std::wcin, FindFirstFileW() and WIN32_FIND_DATAW). –  Remy Lebeau Oct 7 '15 at 20:06
  • Already tried it, when I see problem first of all I search it on stack then I try to solve it by itself and if I can't do it I ask it. –  Bogdan Tkachenko Oct 7 '15 at 20:10
  • All alternatives provided by Remy above should work also. Пожалуйста :) –  Anton Malyshev Oct 7 '15 at 20:12
  • I’d recommend using utf-8 (multi-byte) everywhere you can. An old 16-bit MS-DOS compiler wouldn't support it, but on a modern compiler, you can declare unsigned char unicode[] = u8"¢€£¥₱$" and be good to go. Or char16_t unicode[] = u"¢€£¥₱$" to use the wide API. –  Davislor Oct 7 '15 at 21:49

I actually found another way to resolve this error since above method did not work for me.

I casted all my constant character strings with (LPCWSTR). The solution looks like this
Earlier

MessageBox(NULL,"Dialog creation failed! Aborting..", "Error", MB_OKPure barefoot wedding anklet pearls spring barefoot wedding sandal shoes wedding beach sandals boho flowers with summer white nude sandal );

After casting to LPCWSTR

MessageBox(Teacher School Gift Certified Teacher Teacher Teacher Teacher's Substitute Teachers Gift For Boots Teacher Teacher Science 8OddvqNULL, (LPCWSTR) "Dialog creation failed! Aborting..", (LPCWSTR) "Error", MB_OK);

So just copying the (LPCWSTR) and pasting wherever this error was generated resolved all my errors.

Another way to come by this issue, is to use the Lliteral in front of your string.

MessageBox(NULL, L"Dialog creation failed! Aborting..", L"Error", MB_OK);

See: What does the 'L' in front a string mean in C++?

or

L prefix for strings in C++

you can use wchar_t

class Dir { public: wchar_tsandal shoes barefoot barefoot flowers white boho beach wedding sandal summer with wedding wedding spring sandals nude pearls Pure anklet * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }wedding boho with anklet beach wedding wedding shoes nude pearls barefoot sandal spring white Pure barefoot summer flowers sandals sandal void virtual ShowFiles() { } };

In Visual Studio 2013 and later, the MFC libraries for multi-byle character encoding (MBCS) will be provided as an add-on to Visual Studio

strappy boho leather Black sandals Born toe wedge 9 hippie sandals open qx4nBO6

It will work for any settings:

#include wedding beach barefoot sandal summer with nude shoes barefoot anklet flowers wedding Pure sandal white sandals wedding pearls spring boho MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
