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.

Hi all
I have a window (CWnd) which inside i have a CDialog.
the CWnd contains 2 buttons. the dialog inside contains some controls.
i use the editor for tab ordering in the dialog.
i want now when i stand of the last control of the dialog and pressing tab , to jump to my first button in the CWnd, then pressing tab again to jump to the second button, and pressing tab again
to jump into the first control of the dialog....
is there a way to do that? how do i set the proper order?
thanks

You have to specify the "Control" style to the dialog in the More Styles of the Dialog Properties in Dialog Editor. Also don't forget to specify the WS_TABSTOP style to the buttons those are in the CWnd.

Aparantly i was able to make it work when i defined the WS_EX_CONTROLPARENT for the inner dialog
but the problem is that the main window is a CWnd and not a CDialog, so tab isn't working at all if i stand on a control on the CWnd....if i change the class from CWnd to CDialog then all is working 100%
how to solve this?

I have a project that I am working on that when statically linking to MFC I get the errors listed below. If I link to MFC usinging Dynamic linkage they do not appear. It would be great if anyone could help me resolve this issue.
Much appreciate your time.

Thanks WhiteSky, I went to the help first off. But, the threading model is the same throughout the project. No 3rd party libs or anything that are different threading models.

I think you are trying to use a 3rd party library which is using a different C Run Time then your main application. By looking at error I think your application is using /MTd but at least onee of 3rd Party library is using /MDd. In case it is true then you have to recompile all 3rd party libraries using same CRT.

Hi,
I'm trying to create a custom slider. I've got 5 bitmaps that show the slider's know in 5 different states.
All that is left to do is to change the bitmaps as the user drags the slider.
I've looked in all the articles on the site. All of them use a different approach with regerd to custom drawing of sliders: the knob, the channel and the background are independent objects. I couldn't find an article that implements dynamic replacement of bmps as the user drags the knob.
Can anyone shed some light on what's the best way to implement it?
Thanks a lot in advance.
Snir.
