What I have thought is to develope it, save prototip of the functional code with datum, functions and so on in a lawyer and do it with a patent. Then send it to firms. If they use it... they should pay copyright Wink | ;)

But im not sure about limits and so on, law is not my speciality

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Help me to understand what I'm saying, and I'll explain it better to you

I think that subclassing the desires window could resolve the problem.

What is the logical flow of the program? More specifically, how many functions (did you use) are there and which do what? For instance: In main, such and such is called which does this, then the program returns to main where insert function is called etc... If its not too much trouble id greatly appreciate it.

This is a "how long is a piece of string" question.

The answer will heavily depend on the writer. Some people break pathetically small functions out - other people do their own stack and process things in a loop rather than use recursive functions.

So, the question is...

When you've finished it - then count them. Or ask your teacher what they had planned.

I'd like to do an overlord of operator ++ and -- for my class with templates, like this:
template<typename T> CValueHandler& operator ++ ();
But the thing is, that while it compiles fine, I can't call that overloaded operator.

SomeClass myClass;<br />
myClass++;

Compiler simply complains it can't find a suitable overload.
So, my question is, is it possible to overload ++/-- and use templates too? I can't seem to find a good place to fit in a template type either:

SomeClass myClass;<br />
myClass<UINT64>++;

Doesn't work either.
Using Visual Studio 2005.

Yes, you can overload operators in templates. Take a look into the template of Simon Hughes into the articles (keywords: Smart list). He overloaded operator =, +=, [], and I added the operator == for the lists. So it should be no problem to overload the ++

One thing that I had time ago was...

I was using the ++ and the program was not running ok. I decided to try += 1, and still failed. The i used var = var + 1; and worked ok.

How to make the Program prompt close

James24520-Oct-07 0:43

20-Oct-07 0:43

I'm having trouble with visual studio C++ (orcus)

I'm trying to make my program prompt to Close when
an event is fired.

currently I just have:

Close();

Which works perfectly fine except It does not prompt the user if they really want to close the application or not

I have tried

result= MessageBox::Show("Are you sure you want to exit?","Exit",MessageBoxButtons::YesNo,MessageBoxIcon::Question);

if (result==DialogResult::Yes)
{ Close(); }

but It gives me a Compile error, Saying Result, and Yes
are undefined. Please Someone with C++ knowlege, Help me. Frown | :(

"result" has no defined type. It should be

DialogResult result = MessageBox::Show(...);
