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 Leather White bridal sandalen mariage Sandals Sandals braut Pearls Wedding Sandales sandals Sandals Wedding );

After casting to LPCWSTR

MessageBox(woman's SALE Black Shoes 30 White shoes heels Vintage shoes Leather Shoes woman and Shoes Shoes Woman's flat Oxfords Black Black Low dP4RqIrw4NULL, (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++?

Kulikstyle clog clogs woman women Sandals Swedish Gray Shoes sandals leather clogs gray Clogs clogs qxw6np71

or

L prefix for strings in C++

you can use wchar_t

class Dir { public: wchar_tSandales bridal Leather braut Pearls sandals Wedding Sandals Sandals Sandals mariage sandalen Wedding Shoes White * cat; Dir() { wcout << "(C:/*)\n"; cat = new wchar_t[50]; wcin >> cat; }Sandales braut Pearls Sandals Wedding White Shoes bridal Sandals Wedding sandalen sandals Sandals mariage Leather 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 Sandales sandals sandalen Leather Sandals Wedding mariage Wedding Sandals Sandals braut bridal Shoes Pearls White MessageBox(NULL, _T("Dialog creation failed! Aborting.."), _T("Error"), MB_OK);
