What means "Coding Orros"? I know what Coding Oreos[^] are but never heard of Coding Orros.

Coding Orros refers to members of a family tree: http://www.genealogytoday.com/surname/finder.mv?Surname=Orros[^] who are better at making pizza than coding. http://www.yellowbot.com/orros-pizza-grill-saint-johns-fl.html[^] although obvious to us, it was not obvious to them. After seeing the pizza examples in head-first-design-patterns, you begin to realize how they thought that any pizza maker is automatically a programmer. As you see, the results of pizza makers writing software is extra cheese in our code.

Just figured it out.
Interspersed within the {..} are #define'd a macro (ESCAPEIF(returnvalue) calls. It's defined to 'break' if an error occurrs.
At the end of the function is the cleanup
thus:
do
{
ret = foo(); //returns a '1'
BREAKONERROR(ret);
} WHILE(FALSE);
//perform cleanup (ie: release memory where needed)
Guess I should have followed the white rabbit a little more ..or took the bluepill.

goto is better.

goto is dangerous in C++ if care is not taken because jumping out of scope will NOT result in the destructors of any C++ objects in the scope.

C++ has try-catch blocks, usually goto is not needed.

It's better than using the ugly GOTO method. In a loop you have the option of using break and continue. In this case it's a loop to be run once, unless directed to do otherwise.

better how? If you mean more readable I would argue that at best it is indistinguishably better.

I agree that this code is most probably the replacement for goto, but dissagree that it is better. It is even worse, because it hides the intention.

After a user click, I am pulling a value from a control, converting this into a decimal value and relaying it to another control. The theory is correct, but I just cannot get my code to produce the correct value. This is the formula:
double dZoomFactor = 1 / ( 1 << ( 16 - dwId ) );
where dwId is an integer value between 1 and 16;
In theory:
dZoomFactor = 1 / ( 1 << ( 16 - 1 ) );<br />
dZoomFactor = 1 / ( 1 << 15 );<br />
dZoomFactor = 1 / 32768;<br />
dZoomFactor = 0.000030517578125;
But, the output is always a flat '0.0'. What am I missing?

double dZoomFactor = 1.0 / 32768.0;

That comes out as 3.0517578125000000e-005. Wish I payed more attention to maths back in school. Right now I'm trying to find out what that e-005 means.

WalderMight now I'm trying to find out what that e-005 means.
It means 10^-5, i.e.
3.0517578125000000e-005 = 0.000030517578125000000

Thankyou thankyou thankyou. I have been on google for the last hour trying to find the meaning of that, but every page seems to think it's a universally understood system, kinda makes me feel stupid 
Anyway, my code is now working. Thanks for the help guys

You should probably be using double constants (e.g., 1.0, 16.0), so that the math library is properly initialized.
BTW, your name wreaks havoc in the Quote Selected Text feature. It inserts a malformed </b> tag.

That's exactly what I was doing wrong, but that exponent was giving me a real headache, I thought the wrong values were coming out. I hate floating point maths!

Hello everyone,
Are there some formal documents about which physical files contain C++ related libraries' implementation on Windows (i.e. something like mscvp*, to run and build C++ application, all required static lib, import lib and DLL)?
How about the physical files for C (i.e. CRT) and for all Windows API?
BTW: maybe my question should be asked in another way -- the frequently used DLLs (like user32.dll) and related functions, import libraries and static libraies for Windows platform?
thanks in advance,
George

No. And if it they did exist you certainly would not find them on the Microsoft web site.

Thanks led mike,
What are the frequently used DLLs on Windows and their related functions, like user32.dll? Any referred link about this?
