How to delete an object by giving time limit to it.
Like, if an object is not referenced by anyone for say 5 minutes then it must get deleted by itself.
Please give me some logic for this.

Set a timer after last refernced when that timer complete, delete the object!

CString strMessage;
strMessage.Format ("var = %d", m_terma);
AfxMessageBox (strMessage);
You're probably better off using the TRACE() macro.

i think m_terma is of type integer.
so this
CString csMsg;
csMsg.Format("%d", m_terma);
AfxMessageBox(csMsg);
try it out

CString str; <br />
int m_terma=20;<br />
<br />
str.Format ("Value = %i", m_terma); <br />
AfxMessageBox (str);<br />
------------------------------------<br />
TCHAR buffer[50];<br />
itoa(m_terma,buffer,10);<br />
AfxMessageBox (buffer);<br />
------------------------------------<br />
TCHAR buffer2[50];<br />
wsprintf(buffer2,"Value = %i",m_terma);<br />
AfxMessageBox (buffer2);<br />

What about setting the breakpoint after UpdateData, and seeing the value in the Quick Watch Window!

If this is your actual C++ code:
CString sPath = "c:\some folder\some file.txt"
then it's wrong. The \s will be treated as one character. In a string literal, \ is a special character, and you write \\ to get one backslash.

Are you sure that you need this conversion???
The char \ is coded into the symbol \\ only to find a way to tell at the compiler that we want to use that char: So I can't understand why you need this char conversion: they are only 2 way to see the same thing.
And this is the reason because the first line
(
CString sPath = "c:\some folder\some file.txt"<br /> )
is wrong(see \s, as is saying Michael), and you can't use it.
Hope it helps.

hi all 
can anybody explain me what is the difference, between C++ structs and classes
thanks

Members of structs have public visibility by default, whereas members of classes have private visibility by default. That's it

AFAIK, only one differnence is remain between Struct and Class, that By default member of struct is Public and member of class is private!

Hi,
I am struggling with templates, derived classes and virtual function.
Some help would be highly appriciated.
I have one template class 'RV' and another class 'NormalDistribution' derived from 'RV'
how do I use the NormalDistribution class in the main()??
/////////////////////////////////// template class 'RV' ///////////////
template <typename t="">
class RV { // abstract base template class holding random variables
protected:
T min, max, n;
public:
RV();
void setMinMaxCount(T a, T b, T n)
{ min = a; max = b); }
virtual T generate() = 0;
virtual T pdf(T val) = 0; // virtual functions
virtual T cdf() = 0;
};
template <typename t=""> class NormalDistribution : public RV<t> {
double randNum1,randNum2;
public:
NormalDistribution();
double generate()
{ // some calculations
randNum1 = ra = (((double)rand () / RAND_MAX) * 1);
randNum2 = min + (max-min)*randNum1/n;
rand3=(-log(rand2))/1;
return rand3;
}
double cdf(double val)
{ return (1-exp(-1*val)); }
};
int main()
{
// call 'NormalDistribution' class and assign values to max,min,n and then call generate function
}
////////////////////////////////////////////////
How do I do it?
Thanks,
Tara

Can you tell me how to check a String is double type in MFC?

a string is a string, it is never a 'double' or any other type.
if you want to check if a string represents a floating point number, you need to check for the obvious things: is it all numbers ? does it have an optional single decimal point ? a negative sign in front? an exponent at the end? etc.

you have implement logic to find out that:- you have to check each character of string for Numeral(compulsory),Single 'e' (for exponent,optional) and single Decimal(compulsory). if any of condition fails thne string is definatly not a Float.
