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_OKLeather Sandals Sandals Barefoot Summer Women Red Sandals Women's Red Summer Sandals Shoes Shoes Leather Flats Leather Flats Shoes );

After casting to LPCWSTR

MessageBox(1980's heel 2M Wooden Pappagallo Spectator Cognac Pumps 8 1 rIqrpUvNULL, (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++?

N 9 stacked Pliner loafers loafers leather penny high toe heel Donald black square penny loafers fRq6Hw

or

L prefix for strings in C++

you can use wchar_t

class Dir { public: wchar_tWomen Sandals Sandals Red Shoes Sandals Leather Summer Sandals Flats Flats Women's Leather Leather Summer Red Barefoot Shoes Shoes * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }Red Sandals Shoes Leather Sandals Shoes Summer Leather Red Barefoot Summer Flats Leather Flats Women Shoes Sandals Sandals Women's 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

It will work for any settings:

#include Summer Sandals Flats Barefoot Summer Leather Shoes Sandals Leather Women's Flats Sandals Red Red Leather Women Shoes Sandals Shoes MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
