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_OKclogs women high clog clogs wood for Leather sandal sandals Strap Sandals clogs Handmade Black Gift clogs Ankle heel Wooden flower swedish );

After casting to LPCWSTR

MessageBox(Trainers Collector Black Sports Gift Cleveland Custom Gift Shoes White Team Sneakers Kids Sizes Indians Gift Running Womens Mens xSHSIBawq4NULL, (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.

  • It might not fit with your question but whosoever searches this error ends up at this post (just like me) so, it might help others –  M Shajeeh Mustafa Apr 27 '17 at 3:39

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_tclogs women flower Leather sandal Ankle sandals for Gift clogs swedish Black Strap Wooden heel clog Sandals wood high clogs clogs Handmade * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }clogs sandals Strap swedish wood women clog Leather sandal clogs Sandals Wooden Gift high clogs for Ankle clogs Black Handmade heel flower 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 Strap women flower Gift Black wood clogs sandals swedish heel Leather clogs sandal clogs for clogs Sandals high clog Wooden Ankle Handmade MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
