Well, i don't know what's the best method to handle an exception, i mean in delphi i just do it like:

Code:

begin
try
//Code the fails here
except
exit; //exits from the procedure without showing access violation or any error box unless you're doing debug check
end;
end.

but in C++ i see people use:

EXCEPTION_EXECUTE_HANDLER
or
some_except& e
or
EAccessViolation EErrorCheck

try/catch-except

which one to use ? and what's the different ?

i'll be more specific when i get home.

Code:

__try {
// Rot1 code
}
__except(EXCEPTION_EXECUTE_HANDLER) {
// Save Rot1
}

If you want smaller and faster code, don't use exeptions. They're slowwwwwwwwww and hog resources.

On this note, for anyone using c++ who does not want to support exception handling, simply do the following for each of your functions:

Code:

void SomeClass::SomeFunc(void) throw()
{
// code here
}

So what exactly does that do?
And you're example is a class function, can it also be applied to normal functions?

Doesn't matter if it's a part of a class or not.

Just don't enable it. VS has it enabled by default, you may disable it from the preferences.

True enough, I just do it because some functions you may actually want exception handling.

It strips any code from the function that would be generated with exception handling in mind. It's basically telling the compiler: "I'm perfect, I don't throw exceptions, fuck off."

It can be used in normal functions.
