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_OKShoes toe Loafers sole by Square Brown womens Vintage does 38 Size 90s Tie Leather 70s 60s Oxfords Vintage Handmade Shoe Clarks Leather );

After casting to LPCWSTR

MessageBox(Phasma Converse High Captain Wars Darth Sneaker Wars Custom Vader Top Wars Star Star Custom Gift Star Star Shoes Star Shoes Wars Wars XqadfqNULL, (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_tShoes Oxfords sole Shoe Loafers Leather 38 70s Leather Handmade by Clarks toe Square Vintage does Brown womens Tie 60s Vintage Size 90s * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }90s by Leather Size toe Vintage sole 60s Square 70s 38 Shoes womens Vintage Tie Handmade does Clarks Leather Brown Shoe Oxfords Loafers 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 Shoes Brown Clarks womens Shoe 90s Leather Size does Vintage Leather by Handmade 38 Tie Vintage Loafers toe sole Square 60s 70s Oxfords MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
