What happens if you simply leave out the "? true : false" part?

Well, this code is 100% correct imo (under some conditions).
If Variable is an Integer, the Visual Studio C++ compiler shows a warning (C4800, type' : forcing value to bool 'true' or 'false' (performance warning)) when you use the following code:
int i = 1;<br />
bool c = i;
So, I guess the guy only wanted to get rid of the compiler warning

While it may be correct, it could also have been written:
bool isValue = (instance.Variable == 1); . The true/false at the end is redundant.

It is when there are about 30 of these tests in the same routine.

I have to disagree. Amongst beginners tertiary operators are notoriously hard to read. Anybody who adds them superflously does deserve the hall of shame.

AFAIK, there is just one single value (for a 'bool') that's really defined, and that is the value for false (0).
True is defined as 'not false', so it can be any value, except for 0.
In Win32, there are cases where 'true' can be either 1 or -1.
An example:
TRUE is 1
VARIANT_TRUE is -1
So IMO, the code would be useful if it looked like this:
bool isValue = (instance.Variable == 0 ? false : true);

Better still:
bool isValue = (instance.Variable != 0);
To me this is clearer.
Failure is not an option - it's built right in.

I would do it the same way you do.
I had two reasons for responding the way I did:
1.
I wanted the smallest possible alteration to the original code.
2.
In the past, I have given "smartcoded" examples and has been flamed for it, with comments like "unredable" and "impossible to understand". (My response that the compiler could handle my source code yielded heaps of "1" votes.)
So now I try to keep my code examples as easy to understand as possible.

I actually posted this because I didn't see the need for the true/false test. The result of the equality test is a boolean condition, so either the item is equal to 1 (true) or it isn't (false). It just seemed that the coder had put in unnecessary code because he thought it was clever.
What made it worse, was that there were about 30 of these tests in one routine. Argggh.

Yes, under normal circumstances, it's a total waste, I agree.
The reason why I responded in the first place was that I once spent quite some time to figure out why a function (that turned out to want a VARIANT_BOOL) didn't react when I sent a (BOOL) TRUE to it.
Then I learned the difference between (BOOL) TRUE (1) and (VARIANT_BOOL) TRUE (-1).
And after that, I always test for false or not false. It can't go wrong. All versions of false *is* 0 and nothing else.

Well, may be it's not the best way, but there could be good resons:
1) instance.Variable is a generic class you don't know the type, but you kow it supports bool operator==(int). Assuming that an implicit conversion to bool will do the same is not obvious. (And such a conversion may be even not existent)
2) if instance.Variable is an int, assigning an int to a bool gives a warning. That code eliminates it
2a) But there is a int-to-bool native converter: the !! pseudo-oprerator
bool isValue(!!instance.Variable);

OK. Perhaps I'm being a bit too subtle here.
bool isVariable = (instance.Variable == 1); That's it. That's all you need to do. The check instance.Variable == 1 will only return true or false so there's no need to the ? true : false check. They are redundant.
As I've stated before - this method did about 30 of these checks. The comparison is redundant in each case.

I found this piece of code on the server side of an ASP.NET C# application. I think he was waiting for the text to change at the browser side before continuing. It didn't take me long to figure out why the page kept locking up.
while (Textbox3.Text == "")
{
}

This one gave me a good laugh:
if (index == 1 || 2)
{
...bla
}

Another reason to like C#
Perhaps also another argument for the fans of
if ( 1 == index ) { ... }

When I was a noob programmer I would do things like that.
if (index == 1 || index == 2)

I think that's easier to read, and less ambiguous than this since you don't have to wonder if the equals was intended or a strict less than was actually wanted.
if ((1 <= index) && (index <= 2))

You just have to be careful sometimes because some bizarre languages and/or compilers might have different precedence. I'm guessing that's what he means, to be safe I for one always put in the braces just to make sure it's doing what I want and not what it wants.

hence the full stop at the end of the sentence not a colon. I should check english syntax aswell as code.
Thanks for the response.
