Convert wchar_t* to char* - VC++

Convert Unicode character to No set

Method1:

//if succeed returns newly allocated char pointer.else NULL. //Note-> the return pointer should be deleted char* WideCharToChar(LPCWSTR lpWideCharStr) {       size_t length = wcslen(lpWideCharStr);       ++length;       char* lpszConvertedStr = new char[length];       int nReturnVal =  WideCharToMultiByte( CP_OEMCP, 0, lpWideCharStr, -1,lpszConvertedStr, (int)length, NULL, NULL );       //If not succeed delete pointer       if( 0 == nReturnVal)       {             delete[] lpszConvertedStr;             lpszConvertedStr = NULL;       }       return lpszConvertedStr; }

Method2: Using CStringT

Everybody know that CString is the typedef of ATL::CStringT So we can convert Unicode character to No set with the help of these template class. Example:       CStringW strUnicode = L"Unicode String";       CStringA strNoUnicode = "Non Unicode string";       strUnicode = strNoUnicode;// here  non unicode to Unicode.       strNoUnicode = strUnicode;// Unicode to non unicode
