Hi Raju,
I have a few questions for you !!!! 
1. Which operating system you are using?
2. Are you dealing with multilingual operating systems/system setting
Basically, dialog boxes uses Dialig units(DLU) for creating dialog. So your dialog size depends on the font you are using/char set you are using..
Please have a look at this angle..

The STL provides several container classes like list, map,... and algorithms which cover at least a part of your needs.

Good day,
I have a variable vara, varB.
varA is allocated first. However when I allocate varB due to size, it reaches to the memory area allocated for varA. In this case how can I transfer data so that there will be no memory overlapping which cause access violation error.
Thanks

No way ! If you have allocated memory for varB, when you then allocate memory for variable varA, it will never take memory allocated for the first one. For me it's sound more that you are writing outside the borders of varB and thus writing perhaps in the memory allocated for varA.
Show us the code if you want more help

hello everyone,
i am an application programmer.I have rcently made one package that can calculate arithmetic,combinatronic trignometric functions upto any no. of decimal places. But the problem I am facing is that the execution time increases with the number of digits.This is bcoz I am using auxillary memory instead of RAM.
Can anybody suggest some ways to reduce time delays.
The application is completely made in C++.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Hi,
Is there a free downloadable C++ Class design tool.
I am not looking a complex tool like UML tools. Simple tool which can represent the class and the properties in form of a diagram..
Thanks,

Hi,
I had posted this query in VC++ and C++/CLI forums only.
I don't see anything wrong in this posting, as my query is applicable in both forums and also, some member of either forum may not be member of the other forum.
IF you know of any such tool please let me know..
Thanks,

Hello to all,
i am the beginner of c++ and i wrote some program in Borland C++ 5.0 abt the inheritance this is what i wrote
#include "iostream.h"
#include "conio.h"
class st_Det
{
protected:
int rol_no;
public:
st_Det(){}
st_Det(int a){rol_no=a;}
void put_No(void){ cout<<"\nRoll No :"<<rol_no<<endl;}
};
class st_mark_det:public="" st_det
{
="" protected:
="" float="" sub1,sub2;
="" public:
="" st_mark_det(){}
="" st_mark_det(float="" a,float="" b){sub1="a;sub2=b;}
" void="" put_mark(void){cout<<"\nmarks\n="" subject1="" "<<sub1<<"\nsubject2="" "<<sub2;
};
class="" st_sprt
{
="" score;
="" st_sprt(float="" a){score="a;}
" put_score(void){cout<<"\nscore="" in="" sports\n"<<score<<endl;}
};
class="" result:public="" st_mark_det,public="" total;
public:
="" result(int="" b,float="" c,float="" d):st_det(a),st_mark_det(b,c),st_sprt(d)
="" {total="0;}
" sum(){total="sub1+sub2+score;}
" display="" (void){="" put_no();put_mark();put_score();cout<<sum();}
};
int="" main()
{
="" cout<<"\nenter="" student="" roll="" no:\t";int="" a;cin="">>a;
cout<<"\nEnter Marks In tow subjects";float b,c;cin>>b>>c;
cout<<"\nEnter Score In Sports :\t";float d;cin>>d;
result s1(a,b,c,d);
result.display();
getch();
return 0;
}
but it is giving compile time error like this
st_Mark_Det must be a previously defined class or struct

cnu...

This is not valid C++, you need to include iostream without the h, and hte include should be in < > instead of quotes.

Where do you get the error ?
mcnu wrote:
class result:public st_Mark_Det,public st_Sprt
I don't think this syntax is correct. I think you need to lose 'public'.

I think in borland, this is valid (if I remember my classes correctly, because we were using borland  ).
Christian Graus wrote:

The difference between "" and <> is the search locations for the file. With "", the compiler will first look in the current directory to find the file then in the include directories. With the <>, it will be the opposite.

The syntax is correct.

Regarding iostream.h, VC up to 2005 offers this header as well, but it's still not valid C++. It's finally removed in VC2005, and any half decent C++ programer should not have used it for at least 5 years now.

Yes, I know

OK, then it's definately not valid C++, no matter what some compiler hack allows

This is not really a good design practice because normally, this must be the st_Mark_Det constructor that should call the st_Det constructor instead of result calling directly it. You can add a new parameter in st_Mark_Det constructor and use this new parameter to call the constructor of st_Det inside the constructor of st_Mark_Det.
I never tried what you did so I don't know if this could be the source of an error or not. But still, this is not really good looking.
Otherwise, your code looks good...

i feel your correct and i wrote what you said i added one new parameter in <B>st_Mark_Det<B> constructor to intialize the member varible in the <B>st_Det<B> and that not giving any errors.
and my atual error is what i said earlier
after compiling my program it gives compiler error like this <B> st_Mark_Det must be previously defined class or sturuct<B>
#include <iostream.h>
#include <conio.h>
class st_Det
{
protected:
int rol_no;
public:
//st_Det(){}
// st_Det(int a){rol_no=a;}
void put_No(void){ cout<<"\nRoll No :"<<rol_no<<endl;}
};
class st_Mark_Det:public st_Det
{
protected:
float sub1,sub2;
public:
// st_Mark_Det(){}
st_Mark_Det(float a,float b,float c){rol_no=a;sub1=a;sub2=b;}
void put_Mark(void){cout<<"\nMarks\n SUBJECT1 "<<sub1<<"\nSUBJECT2 "<<sub2;
};
class st_Sprt
{
protected:
float score;
public:
st_Sprt(float a){score=a;}
void put_Score(void){cout<<"\nScore In Sports\n"<<score<<endl;}
};
class result:public st_Mark_Det,public st_Sprt
{
float total;
public:
result(int a,float b,float c,float d):st_Mark_Det(a,b,c),st_Sprt(d)
{total=0;}
float sum(){total=sub1+sub2+score;}
void display (void){ put_No();put_Mark();put_Score();cout<<sum();}
};
int main()
{
cout<<"\nEnter Student Roll NO:\t";int a;cin>>a;
cout<<"\nEnter Marks In tow subjects";float b,c;
cin>>b>>c;
cout<<"\nEnter Score In Sports :\t";float d;cin>>d;
result s1(a,b,c,d);
result.display();
getch();
return 0;
}

At which line is the error displayed ? (Don't post the line number but the complete line). Post also the exact error message.
|

Geeez, pretty difficult to find this error !
The error is at this line:
class st_Mark_Det:public st_Det<br />
{<br />
protected:<br />
float sub1,sub2;<br />
public:<br />
st_Mark_Det(float a,float b,float c){rol_no=a;sub1=a;sub2=b;}<br />
void put_Mark(void){cout<<"\nMarks\n SUBJECT1 "<<sub1<<"\nSUBJECT2 "<<sub2;<br />
};<br />
You forgot the '}':
void put_Mark(void){cout<<"\nMarks\n SUBJECT1 "<<sub1<<"\nSUBJECT2 "<<sub2; }
That's one reason why putting all the code in one single header file is so bad: it's almost impossible to spot the corresponding '}'. Also, you should really use a better way of 'formating' your text. The purpose here is not to have the smallest number of lines but to have a code that is readable
