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

After casting to LPCWSTR

MessageBox(Infinity Custom Avengers Converse Avengers Shoes Shoes War War White War Infinity Sneaker Converse Infinity High Avengers Top Custom BwaU0q4IFNULL, (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_thigh sandals heel swedish clogs Leather for Wooden clogs sandal clog women Black Gift Sandals Handmade clogs Strap flower Ankle clogs wood * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }flower sandals clogs clogs swedish Black Ankle clogs Gift clog heel Leather women clogs Wooden high wood sandal for Strap Sandals Handmade 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 clogs high Ankle wood swedish clogs clog Strap Black Sandals Wooden clogs Handmade sandals for flower clogs sandal Gift Leather heel women MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
