The first thing you need to do is research how to transfer data from disk to DVD, a Google search will probably help you.

It's time for a new signature.

Im trying to pass more than one parameter which I transformed to a thread.

Since the thread function accepts a void * as argument (or type compatible with), you may pass a pointer to a whole struct of parameters.
Moreover, the thread functiom may access global variables (however, you shouldn't abuse of).

Try avoiding using globals at all costs. There are very few situations in which you have to use global variables.

I don't completely agree with you. It may be a quick good rule for the newbie. On the other hand the experienced may choose using globals (for instance in small, self-contained projects)

You're right. I've reread my message and I sounded like such a Troll.

There are situations in which using globals is not a bad idea. If you have something like:
static const std::string application_name = "MyApplication";
passing it as a parameter is counter productive. So this is a situation in which you SHOULD use globals.
However, most times, passing variables as arguments rather than using globals is a better design choice.

Alternatively he can use static members of a class instead of "pure" globals, that "looks a bit more object oriented". Smile | :)

I have no idea what the library you're using is doing, but have you looked up the documentation for that exception and found what sort of thing is happening when it's thrown?

Perhaps catch the exception and have a look and see if there's any hints as to what caused it? Has it a message function that'll give you a clue as to what happened? Line number of file information as to where it happened?

Cheers,

rounding doubles to set # decimal places

b-rad31118-Jun-10 8:33

Hi,

Does anyone know if there's a built in function in c++ or mfc in which you can pass a double or long double and declare how many places you'd like the value to be rounded to? For example, pass it 12.125 and n=2 decimal places, and out comes 12.13, etc.

Thanks!

P.S. Formatting the values during cout won't work for me, I need to store the rounded values in a new variable.

I don't do a lot of numeric stuff anymore so take this with a pinch of salt.

First off I don't know any C++ standard library facilities that would help. C had floor and ceil which take doubles and return an integer either truncating the value or rounding up to the next highest number. With these and pow you can write something that'll be good enough for most things.

Off the top of my head it'd look like:

double round_to( double number, unsigned number_of_decimal_places )
{
    double exponent( pow( 10, number_of_decimal_places ) );
    number *= exponent;   // disaster line!
    number += 0.5;
    return floor( number ) / exponent;
}

which is a bit cheesy - it won't work for negative numbers or any number that causes the line with the "disaster line!" comment to overflow an integer. However they might give you a handle if no one comes up with a better idea!

Cheers,

Ash

You may use the dirty old town's trick:

double rounded(double x, int n)
{
  double d = pow(10, (double)n);
  return ((int)(x * d + .5))/d;
}

Excellent, this did exactly what I was needing. Thanks!

One thing I noticed was when I used -265.3215894 with n=2, it returns -265.31 instead of -265.32
Any thoughts on this?
