char *, wchar_t *, _bstr_t, CComBSTR, CString, basic_string, System.String 변환
char *
char *orig = "Hello, World!"; size_t origsize = strlen(orig) + 1; // wchar_t * const size_t newsize = 100; size_t convertedChars = 0; wchar_t wcstring[newsize]; mbstowcs_s(&convertedChars, wcstring, origsize, orig, _TRUNCATE); wcscat_s(wcstring, L" (wchar_t *)"); _bstr_t bstrt(orig); // _bstr_t bstr += " (_bstr_t)"; CComBSTR ccombstr(orig); // CComBSTR if(ccombstr.Append(L"(CComBSTR)") == S_OK) CW2A printstr(ccombstr); CString cstring(orig); // CString cstring += " (CString)"; string basicstring(orig); // basic_string basicstring += " (basic_string)"; String ^systemstring = gcnew String(orig); // System.String systemstring += " (System::String)"; delete systemstring; |
wchar_t *
wchar_t *orig = L"Hello, World!"; size_t origsize = wcslen(orig) + 1; // char * const size_t newsize = 100; size_t convertedChars = 0; char nstring[newsize]; wcstombs_s(&convertedChars, nstring, origsize, orig, _TRUNCATE); strcat_s(nstring, " (char *)"); _bstr_t bstrt(orig); // _bstr_t bstrt += " (_bstr_t)"; CComBSTR ccombstr(orig); // CComBSTR if(ccombstr.Append(L" (CComBSTR)") == S_OK) CW2A printstr(ccombstr); CString cstring(orig); // CString cstring += " (CString)"; wstring basicstring(orig); // basic_string basicstring += L" (basic_string)"; String ^systemstring = gcnew String(orig); // System.String systemstring += " (System::String)"; delete systemstring; |
_bstr_t
BSTR을 캡슐화하는 COM 지원 클래스 (comutil.h, comsuppw.lib 또는 comsuppwd.lib)
_bstr_t orig("Hello, World!"); const size_t newsize = 100; // char * char nstring[newsize]; strcpy_s(nstring, (char *)orig); strcat_s(nstring, " (char *)"); wchar_t wcstring[newsize]; // wchar_t * wcscpy_s(wcstring, (wchar_t *)orig); wcscat_s(wcstring, L" (wchar_t *)"); CComBSTR ccombstr((char *)orig); // CComBSTR if(ccombstr.Append(L" (CComBSTR)") == S_OK) CW2A printstr(ccombstr); CString cstring((char *)orig); // CString cstring += " (CString)"; string basicstring((char *)orig); // basic_string basicstring += " (basic_string)"; String ^systemstring = gcnew String((char *)orig); // System.String systemstring += " (System::String)"; delete systemstring; |
CComBSTR ATL의 BSTR wrapper 클래스 (atlbase.h)
CComBSTR orig("Hello, World!"); CW2A printstr(orig); const size_t newsize = 100; // char * char nstring[newsize]; CW2A tmpstr1(orig); strcpy_s(nstring, tmpstr1); strcat_s(nstring, " (char *)"); wchar_t wcstring[newsize]; // wchar_t * wcscpy_s(wcstring, orig); wcscat_s(wcstring, L" (wchar_t *)"); _bstr_t bstrt(orig); // _bstr_t bstrt += " (_bstr_t)"; CString cstring(orig); // CString cstring += " (CString)"; wstring basicstring(orig); // basic_string basicstring += L" (basic_string)"; String ^systemstring = gcnew String(orig); // System.String systemstring += " (System::String)"; delete systemstring; |
CString ATL/MFC의 템플릿 클래스인 CStringT의 기본 구현 클래스.
CString orig("Hello, World!"); const size_t newsize = 100; // char * char nstring[newsize]; strcpy_s(nstring, orig); strcat_s(nstring, " (char *)"); // wchar_t * (이 작업을 하려면 먼저 char *로 바꿔야 한다) size_t origsize = strlen(orig) + 1; size_t convertedChars = 0; wchar_t wcstring[newsize]; mbstowcs_s(&convertedChars, wcstring, origsize, orig, _TRUNCATE); wcscat_s(wcstring, L" (wchar_t *)"); _bstr_t bstrt(orig); // _bstr_t bstrt += " (_bstr_t)"; CComBSTR ccombstr(orig); // CComBSTR if(ccombstr.Append(L" (CComBSTR)") == S_OK) CW2A printstr(ccombstr); string basicstring(orig); // basic_string basicstring += " (basic_string)"; String ^systemstring = gcnew String(orig); // System.String systemstring += " (System::String)"; delete systemstring; |
basic_string STL 클래스 (<string>)
string orig("Hello, World!"); const size_t newsize = 100; // char * char nstring[newsize]; strcpy_s(nstring, orig.c_str()); strcat_s(nstring, " (char *)"); // wchar_t * (이 작업을 하려면 먼저 char *로 바꿔야 한다) size_t origsize = strlen(orig.c_str()) + 1; size_t convertedChars = 0; wchar_t wcstring[newsize]; mbstowcs_s(&convertedChars, wcstring, origsize, orig.c_str(), _TRUNCATE); wcscat_s(wcstring, L" (wchar_t *)"); _bstr_t bstrt(orig.c_str()); // _bstr_t bstrt += "(_bstr_t)"; CComBSTR ccombstr(orig.c_str()); // CComBSTR if(ccombstr.Append(L" (CComBSTR)") == S_OK) CW2A printstr(ccombstr); Cstring cstring(orig.c_str()); // CString cstring += " (CString)"; String ^systemstring = gcnew String(orig.c_str()); // System.String systemstring += " (System::String)"; delete systemstring; |
System.String .NET 프레임워크 클래스 (mscorlib)
String ^orig = gcnew String("Hello, World!"); pin_ptr<const wchar_t> wch = PtrToStringChars(orig); size_t origsize = wcslen(wch) + 1; // char * const size_t newsize = 100; size_t convertedChars = 0; char nstring[newsize]; wcstombs_s(&convertedChars, nstring, origsize, wch, _TRUNCATE); strcat_s(nstring, " (char *)"); wchar_t wcstring[newsize]; // wchar_t * wcscpy_s(wcstring, wch); wcscat_s(wcstring, L" (wchar_t *)"); _bstr_t bstrt(wch); // _bstr_t bstrt += " (_bstr_t)"; CComBSTR ccombstr(wch); // CComBSTR if(ccombstr.Append(L" (CComBSTR)") == S_OK) CW2A printstr(ccombstr); CString cstring(wch); // CString cstring += " (CString)"; wstring basicstring(wch); // basic_string basicstring += L" (basic_string)"; delete orig; |
정말 감사감사하다 ㅠㅠ 진짜 흑흑
