i have created a dialog based application for calender.

coding is
void CcalenderDlg::D blClickCalendar 1()
{
CString cSelectedDate;
char* cDay="";
char* cYear="";

itoa(m_calender .get_Day (),cDay,10);
cSelectedDate=c Day;

switch(m_calend er.get_Month ())
{
case 1: cSelectedDate+= "Jan";
break;
case 2: cSelectedDate+= "Feb";
break;
case 3: cSelectedDate+= "Mar";
break;
case 4: cSelectedDate+= "Apr";
break;
case 5: cSelectedDate+= "May";
break;
case 6: cSelectedDate+= "Jun";
break;
case 7: cSelectedDate+= "Jul";
break;
case 8: cSelectedDate+= "Aug";
break;
case 9: cSelectedDate+= "Sep";
break;
case 10: cSelectedDate+= "Oct";
break;

}
itoa(m_calender .get_Year (),cYear,10);
cSelectedDate+= cYear;
LPSTR OriginChar= cSelectedDate.G etBuffer(0);

MessageBox("U dbl Clicked");
//////MessageBox("u dbl clicked",Origin Char,MB_OK);
//cSelectedDate.R eleaseBuffer();

}

initially it was giving errors with messagebox

You access violation is here:

char* cDay="";
char* cYear="";

itoa(m_calender .get_Day (),cDay,10);

cDay is not a buffer. It is a pointer to a literal. That makes it const. When
itoa() tries to write to cDay is when you get your access violation.

cDay needs to be a char array:

char cDay[10] = "";           //I'm just guessing the 10
