You used five and six (beers of course).

Name collision? Try to rename it OnMyTimer. If it doesn't help, please provide the context of your TIMERPROC declaration (i.e. is it a method?).

Please be more specific on your problem/difficulty: Aren't you able to create a file and write to it?
Aren't you able to build a DLL? Are you using MFC or WIN32?

Thanks for the reply.
I am able to make a DLL file. Using VC++. I have log file which I have to rebuild it into a new format. It uses Multithreading, Mutex's and all. I wanted to know how do I start on it to create a new program that make a DLL file. This DLL file should be able to create the newly formatted log files.
Kindly please let me know regarding this.

I think the above are quite opposite sentences. Please elaborate.
Making a new DLL project with Visual Studio is straightforward.

Yes Making a new DLL projects in VC++. You are right.
apologize for that

In the program below if i try to convert derived class pointer to base with '=' operator overloaded the overloaded operator is not considered. Can somebody please explain what is wrong in the below code?
class base
{
// dummy
};
class Derived : public base
{
public:
Derived* operator= (base* aBase)
{
return (Derived*) aBase;
}
};
int main(int argc, char* argv[])
{
base* bb = new Derived;
Derived* dd = bb; // Compilation error C2440
return 0;
}
|
|
|
|
|
You can't do that. This opposite is possible (casting from a derived class to a base class).
You have to use a dynamic_cast:
Derived* dd = dynamic_cast(base*)<bb>;
Not sure why you would like to do that in this context though.

I understand that you shouldn't convert. But in derived class i have overloaded '=' operator which takes base pointer as argument and explicitly converts it to derived pointer. Still the compiler is throwing an error. Is anything wrong in the overloaded operator?
Actually i am trying to write a linked list to store any data type in one list. So i have a data class (a template class) which is derived from a dummy base class. Each node has a pointer of base class storing derived class object. So while retreiving i will cast base class pointer to detived with template argument(e.g derived<t>*) by overloading = operator in derived class.

What about a good book on OOP, focusing the reading on polymorphism?

The c++ operator oveloading will work only one object. The operator you wrote will work in the below case only
base* bb = new Derived;<br />
Derived dd;<br />
dd = bb;
|
|
|
|
|
No. Before posting i tried that. It doesn't work. Actuallu what you have written should be modified as
Derived* dd = NULL;
dd = bb;

What I mean is if you want the =operator to, you should code in that way.
C.P.Rajesh wrote: Derived* dd = NULL;
dd = bb;
This is just an pointer assigment statement. That is bb is assigned to a pointer of Derived not to an object of class Derived. The operator functions you written on the class will work only for object of that class. not for a pointer of it...

The above code will not work.

And can you tell me why? Since he have overlaoded the operator= (base* aBase), it should definitly work.. I coudnt find any problem...

Of course:
It's class have an assignment operator returning a pointer to Derived not a reference to.
(his design is a bit weird...).
