G'Day.
Anybodey got an idea on this problem.
Say I have a function object doCast(object obj, Type t);
It's job is to cast the obect (obj) to a new type (t) and return it.
Sounds so simple, but I cant seem to find a way to do it without some
prety extravigant hacks.
Can anybodey think of a simple solution that I am overlooking. (um for
..net 1.0)

Opps there is a .net has a function that does this.....
Convert.ChangeT ype(...).
My bad.

Well, normal casting (leaving aside actual conversions) wouldn't do you
any good, because the method signature would still have to be "object".
Are you looking to perform the various implicit and explicit
conversions?

Convert.ChangeT ype performs convertion, not simple cast, and requires
the object to implement IConvertible interface. If you simply want to
cast, the doCast function would make no sense since it returns object
and you have to cast the return value again. Sounds so simple, but I cant seem to find a way to do it without some
prety extravigant hacks
I am curious what are those hacks?

What would be the difference from just doing:
SomeObject x;
SomeOtherObject y = (SomeOtherObjec t)x;
?

You will have to return an object reference, so I find the method itself
pretty useless as it's right now. What are you trying to do?
Hi, What would be the difference from just doing:
SomeObject x;
SomeOtherObject y = (SomeOtherObjec t)x;
The OP do not have SomeOtherObject nor he knows what it's , all he has is a
Type instance representing it.
Hello again, I thought is had solved the problem but as pointed out by
Truong it only works for classes implementing IConvetable.
Basicly I need to convert an object to a new type where the "new type"
is determined at runtime.
I think this is actuly a challange now...
basicly complete this stub:
object doCast(object obj, Type t)
{
object obj;
///magic code goes here to conver obj to type t
return obj;
}
The person with the most elegant solution will win.... "New Zealand".
Dont miss your chance to own your own pacific island nation!
-dm
opps (bad stub, lets correct),
object doCast(object obj, Type t)
{
object newObj;
///magic code goes here to conver obj to type t
return newObj;
}
Idealy this would work....
newObj = obj as t;

Well, how do you expect that conversion to happen? What has the
knowledge to convert one type to another in your code?
For instance, suppose I have two classes:
FirstClass
{
int x;
}
SecondClass
{
string y;
}
How would you expect it to convert an instance of FirstClass into an
instance of SecondClass?

The answer is neither. Use macros.
#define ALLOC(size, type) ((type) *) malloc((size) * sizeof(type))
#define NEW(type, name, size) (type) * (name) = ALLOC((size), (type))
They are both type-safe and concise.
Compare:
NEW(int, x, 1000);

Is it possible to cast a 4-byte data type (e.g. an unsigned int) to a
4-byte struct? Sometimes the HIWORD and LOWORD of a 4-byte value
contain information independent of each other. Is there a direct way
to perform this cast? If not, is there way in C++ to do it?
For example, I would like my function test() to work the way it is
coded below. It produces a compiler error though:
#include <pshpack2.h// 16-bit padding
