Use Unicode and Hide the Console in Windows

 If one would like to make his program being able to accept the arguments which is not English, the Unicode is requisite. That would make your software be more international. ( For me, it is instinct to use Chinese as file name and so forth.)

   To use Unicode in windows, One could set your program as unicode in Visual Studio:

That your could use unicode in your code.

If your program arguments could be Chinese, the main should be the form:

int wmain(int argc, wchar_t *argv[]) 
           

in windows with unicode.

but, if you would like to hide console (for example, if you use Qt librarie with Visual Studio), the well-known solution :

#pragma comment(linker, "/SUBSYSTEM:windows /ENTRY:mainCRTStartup")
           

would not work.

there would be :

error LNK2001: unresolved external symbol _main
           

To solve it as valid is very tricky, that is :

#pragma comment(linker, "/SUBSYSTEM:windows /ENTRY:wmainCRTStartup")
           

To demostrate i, the code be :

#include <windows.h>

#include <locale.h>
#include <wchar.h>



#ifndef _DEBUG
#pragma comment(linker, "/SUBSYSTEM:windows /ENTRY:wmainCRTStartup")
#endif

int wmain(int argc, wchar_t *argv[]) 
{
 int k;
 
 k = 1;
 while(k < argc)
 { 
  wchar_t bufferW[256];
  memset(&bufferW[0], 0, 256*sizeof(wchar_t));
  wcsncpy(&bufferW[0], argv[k], 256);  

#ifdef _DEBUG  
  setlocale(LC_ALL, "");
  wprintf(TEXT("%s\n"), &bufferW[0]);
  
#else
  MessageBox(NULL, &bufferW[0], TEXT("參數"), MB_OK);
#endif
  k++;
 }/*while*/

 return 0;
}/*wmain*/
           

and set the input argument as :

(Of course, do not forget set the character set as Unicode in the configuration properties -> General)

In the debug mode, the output would be in the console :

In the release mode, the console would be hidden, and the output be :
