visual studio 6.0 to 2005

I have created and project in MS visual studio 6.0 as below

#include "stdafx.h"
#include <iostream.h>
class Rational
{
	double r;
public:
	Rational(int numerator, int denominator)
	{
		r = numerator/denominator;
	}
	operator double()const
	{
		cout<<r<<endl;
	}
};

int main(int argc, char* argv[])
{
	Rational r(1,2);
	cout<<r;
	cout<<endl;
	return 0;
}

It works fine.

But when I build the same in MS visual studio 2005, the following error comes

1>c:\problemimplicittypeconversion\implicittypeconversion.cpp(5) : fatal error C1083: Cannot open include file: 'iostream.h': No such file or directory

How to rectify this problem

Change to
#include <iostream>
using namespace std; // and add this line if you don't want to write std::cout everytime

Somethings seem HARD to do, until we know how to do them.

That's not a good idea...

Or at least reduce scope of using declaration.

For e.g.

void SomFuncUsingStd()
{
     using namespace std;
     // Some code...
}

Of course. I do understand that but seeing the code snippet I didn't think that the coder would worry too much about that, Cool | :cool:

and another thing that we do provide optimized solutions but they may not be the best at all times Big Grin | :-D

The search functionality on CP is still active and you can search on google too. Just put Threading as the keyword in the search field
If you need to write some sample for your understanding, you can simply create two threads and do some task like moving an image, counting numbers and printing them on screen etc etc...

atlsmtpconnection.h is available in VS 2005 but not in VS 2008. Also I am not able to find other classes like CMimeMessage etc in VS 2008. Does anyone have any idea whether I need to install anything else to get these classes?

display symbol at some address

Hello everyone,

If there is an arbitrary address (e.g. 0x12345678), how to check whether it is code or data or stack? Any command to display the information (suppose I have symbol file) in the arbitrary address? Could we use WinDbg tool?

thanks in advance,
George

Will the PEDUMP tool do the job for you?

Hi Santosh,

In my understanding, PEDUMP tool dumps human readable information in a static way -- without running the binary. But my purpose is to dump information at runtime at some specific address. Without running, just do static analysis, you do you know what information (code/data/stack) will reside in some specific memory address, right?

Please feel free to correct me if I am wrong. Smile | :)

regards,
George

There is no specific address where each section resides.
You will need to understand the PE format.
It is a chain of data structures.
You will need to examine the PE Header and the PE optional header of the executable to get the starting relative virtual address of each section.

Thanks Santosh,

Sorry I do not agree with you. Suppose my application loads a DLL and I want to debug into the DLL, since DLL could be loaded into any address (possible reload), how could you just get the actual address using static analysis tool without running it? Smile | :)

Please feel free to correct me if I am wrong.

I have a question for you, Santosh. Smile | :)

A DLL could be loaded at any arbitrary address, how could you use PEDUMP to analysis information at some address without actually run/load it. Let me know if I have not made myself understood.

George

Well if you read about PE is very helpful for you and if you like to see it I saw a very good article on the www.codeguru.com about it.
