I am using Visual C++ version 6. From their documentation fstream supports only up to 2GB. I wonder if there is any way to get around this problem.

I wonder if standard fstream supports file size over 4GB?

Oh! I understood your first message now. Thanx again.

Sorry for not being clear. What I meant was, if I instantiated 2 objects of MyMainClass, each object would have its separate "dumbClass" pointer. But I wish them to share the same pointer (that was...

Oh thanx Transformer for reminding me about static nuisance.

I intend MyMainClass to have only a single (global) pointer to an instance of DummyClass. How do I code this?

There are some typos. See my correction below:



// File: DummyClass.h
class DummyClass {
public:
void doNothing() {
}
};

I have the following 2 files:

// File: DummyClass.h
class DummyClass {
public:
void doNothing() {
}
};

// File: MyMain.cpp

I used to combine them even for non-template classes. A while ago, as I developed my program I encountered some problem as I included a header file (non-template class) in more than 1 cpp file....

I used to put my methods implementation together with class definition in the header file. I would like to separate them. The following are my new code:



// File: MyClass.h
#ifndef...

This one works! Moreover it is much compact. Thanx legend

Thanx

I originally coded that way, but I was thinking a user may erroneously instantiate


DummyClass<TestStruct<double>, int> myClas;

which of course results in error(s). So to keep error to the...

I use visual c++ version 6. There are many errors, but the first 2 are:
error C2954: template definitions cannot nest
error C2951: template declarations are only permitted at global or namespace...

your suggestion does not work.

Hi all,

I am having trouble with class definition with template. The following is a simple example:


template <class DataType>
struct TestStruct {
DataType key;
};
