ok... not sure whats going on there but i tried repasting it with and w/o the checkbox and it still shows up erred. Its missing the angle brackets obviously. The code itself is correct syntactically. Just pretend they are there :) If you're real interested in seeing the actual file i can email it. * EDIT: Screw it... just removed HTML completely. should show up right now.

It was already checked. It shows up fully in my browser (chrome) and in IE just fine. Not sure why you can't see it.

I have run into a very strange error today and was wondering if anyone else has seen this. Some digging on google suggests it might be a compiler error. I've seen this on VS2008 and GCC 4.1.2. I was able to build a test harness to repro the issue. It is below:

#include class Cloneable
{
public:
template TYPE* clone() const { return dynamic_cast< TYPE* > ( clone() ); }
virtual Cloneable* clone() const = 0;
};

// simple template class that defines an interface
// for cloning objects.
class X : public Cloneable
{
public:
X(int _y ) : data(_y) { }
virtual ~X() { /* DO NOTHING */ }
virtual Cloneable* clone() const { return new X(data); }

protected:
X() { /* DO NOTHING */ }
int data;
};

class Y : public X
{
public:
Y(double f, int y) : X(y), dataf(f) { /* DO NOTHING */ }
virtual ~Y() { /* DO NOTHING */ }

virtual Cloneable\* clone() const { return new Y(dataf, data); }

protected:
double dataf;
};

// >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

int main(int argc, char* argv[])
{
X* x = new X(1);
X* x1 = x->clone();

Y\* y = new Y(2.12, 4);
Y\* y1 = y->clone();

delete y;
delete y1;
delete x;
delete x1;

return 0;

}

The clone fails in both cases in the main function. It should cast properly. There seem to be two ways to fix this. If i move the templated function from Cloneable to X & Y it works in both cases. The other is to use clone() in the main function and dyna cast there. A standard C cast in the templated function also doesn't work. Its like the compiler is erroneously changing the protection level on the function and then gets confused and just dumps out the error.

Anyone seen this work in a different compiler or know of a workaround to make it compile (aside from the ones I mentioned)? -- Joseph Dempsey Sr. Software Engineer joseph_r_dempsey@yahoo.com

I've paid for them before. The one I used was http://www.iconexperience.com/[^]. They are great quality icons, have a full range of sizes and also include the png versions of each icon in both a shadow and non-shadowed form for all sizes. I paid something like 350 at the time (its been a few years now) but I felt like it was a pretty good value for what I got. I know there are a few others that I looked at and thought were good quality as well but most of them seem to cost over 500.

Never really thought about it that way but its a bit late for that for me. I already have my vista machine fully up and running with everything installed on it.

Yeah I thought of this but I just wanted to avoid trying it and then screwing up my install if it doesn't work the way it should. Well I suppose I'll just ghost my machine first then give it a go :)

Does anyone here have an experience dual booting vista/xp/2k (any combo) and having a single visual studio install. I know some programs offer a "registry only" install so that you can use the same physical installation. I don't want to have to keep multiple copies around but I need to run vista and xp. I tried a quick Google and came up with a whole lot of not much. Any tips, hints, tricks or pointers in the right direction would be greatly appreciated.

I agree. I actually make it a point to take a 10 minute walk during every day. Helps break up the day a bit and lets the body and mind unwind a bit before getting back to work.

Thanks for the comments. Its good to see that people have nice things to say about both the product and the level of support for that product. You just don't see that much anymore. This give me hope that the toolkit will integrate nicely into my application and perform well. Thanks again!
