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_OKBoots Leather Ankle 1990's Brown Western );

After casting to LPCWSTR

MessageBox(Ankle 1990's Boots Leather Brown Western zqwB6q7NULL, (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_tAnkle Leather Brown 1990's Boots Western * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }Brown Western Leather Ankle Boots 1990'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

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

It will work for any settings:

#include Brown Ankle Western 1990's Leather Boots MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
