// date : 2010/07/12
int yy = 2010;
int mm = 07;
int dd = 12;
struct tm tt;
time_t t;
yy -= 1900;
tt.tm_mon = mm;
tt.tm_year = yy;
tt.tm_mday = dd;
t = mktime(&tt);
struct tm *tt2 = localtime(&t);
int ii = tt2->tm_wday;  // run time error ?!!!!

Here is .h file
ex.h
Dialog Data
	//{{AFX_DATA(CSourceDetails)
	enum { IDD = IDD_DIALOG_SOURCE_DETAILS };	

	CMSMask	m_val1;
	CMSMask	m_val2;
  	CMSMask	m_val3;

here is .cpp file
m_val1.GetText(); // I am reading  from the editbox
m_val2.GetText();
m_val3.GetText();

A = B Exp(-0.693 * t/T)
  B = m_val1.GetText();
 t = m_val2.GetText();
T = m_val3.GetText();

I am trying with this.


h = (-0.693 * t/T);
res = B^h;
