I think a day I'll become mad because of a George_George question.

I am sorry to make you mad, CPallini. Maybe my question is too hard?

1. the code shown here calls a member function in the class T which has no parameters and which returns a variable or type R.
2. as said formerly, the function accepts no parameters.
3. it is certainly useful to have such a function, even though it gets no parameters. the point is that is calls such a function in the class T; that means, every class used MUST have such a function existing, but also it means that every class used so defines its own behavior.

Thanks toxcct,
1. I do not quite catch your points, why a class must implement a function without any parameters?
<blockquote class="FQ"><div class="FQA">toxcct wrote:</div>that means, every class used MUST have such a function existing, but also it means that every class used so defines its own behavior. </blockquote>
2. I want to confirm that, the declaration of variable pmf could be pointed to any member functions of class (type) T which returns type R and no input parameters? Right?
R (T::*pmf)()

George

because it does something which doesn't need any further inputs from the caller.
here, the function is used as a functor, that means it is called internally from the STL algorithm you're using, to do a certain action on your class, but the algorithm wouldn't know what to pass it if it had to anyway.

exactly. so, I think the compiler would probably complain (to be verified though) if it canoot determine which function to call if it find more than one.

Hi toxcct,
Your below description is not true. See my sample and it could compile ok.

class Foo
{
public:
int Foo1() {};
int Foo2() {};
};
class Goo
{
public:
int (Foo::*pmf)();
};
int main()
{
return 0;
}

I SAID "I think" and "probably" which denotes a not sure at all. so give me my 5 back, dork

Do you need to SW_MAXIMIZE and SW_MINIMIZE?
|
|
|
|
|
are you asking for WM_MINIMIZE?

I need to create an MFC application that shows the thumbnails reading them from thumbs.db file created by windows OS. Any help would be appricated.
Note: I am able to read the catalog header of the thumbs.db which contains information about no. of thumbnails and their dimesion. The problem is to read the filenames and the actual RGB data.
