C / C++ / MFC

I have Done all the Settings to run the Unicode Program
    1. Added "_UNICODE" in Preprocessor Directives and removes "_MBCS"
    2. Entrypoint in Link tab as "wWinMainCRTStartup"

<code>
	CDatabase cn;
	CString FieldValue1,FieldValue2,FieldValue3;
	CDBVariant varvalue;

	CString csPwd,csUser,csServer,csDBName;
	csPwd = "SQLServer2005";
	csUser = "sa";
	csDBName = "DeccanCollege";
	csServer = "DECCANSERVER";

	cn.OpenEx(_T("DRIVER={SQL Server};Pwd="+csPwd+";Uid="+csUser +";Database="+csDBName+";Server="+csServer),CDatabase::noOdbcDialog);

	TCHAR *m_Voc = (TCHAR*) malloc(50); //allocate memory
        m_VocEdit.GetWindowText(m_Voc,50);     // get Edit box Unicode Value

//Suggest How to Pass "m_Voc" value as Unicode
	CString sqlStr = _T("Select * from Vocablemaster where slvid in(Select slvid from slipvocmaster where binno between 165 and 169) and (VocDescSan like N'%"+CString(m_Voc)+"%')");
	CRecordset rec(&cn);
	rec.Open(CRecordset::forwardOnly,sqlStr,CRecordset::none);

   while(!rec.IsEOF()) 
	{
		rec.GetFieldValue((short)0,FieldValue1);
		rec.GetFieldValue((short)1,FieldValue2);
		rec.GetFieldValue((short)2,FieldValue3); 
		rec.MoveNext();
	}

double x = 1051450100212345678903111694;
double BigX = 100 * x;
double y = 97;

double z = modf(BigX, & y); 

i always have 0 in z

while (BigX >97)
   BigX =  BigX - (BigX/97);
