I cant believe the output:
5 5 5
I tried your code and it says "7 6 5". What is right.
And the 8 7 6 7 6 5 from the prev. problem i also said that
the compiler output is correct.

All of this "I expected..." and "it should be..." stuff is pointless. Compiler vendors are free to evaluate such expressions as they wish just so long as all side effects of previous evaluations have been performed at each sequence point. In your printf example, the order in which the arguments are evaluated is not specified, but the sequence point means that all of their side effects are complete before printf() is entered.

What I mean to imply here is that based on what I have read/know the output should have been so and so.....So may be my understanding of this concept (of calling convention, sequence points) needs to be brushed up....It *could be* my ignorance on the matter, lets see, I'll read more, do more research and see what's missing 
DavidCrow wrote: Compiler vendors are free to evaluate such expressions as they wish just so long as all side effects of previous evaluations have been performed at each sequence point.
Expressions....true, but the point here is about "passing variables" and C does specify how to do that: either R-to-L or L-to-R, we can make that selection.

I did not specify that but I m using the default calling convention under which variables are passed R-to-L

Does pCollection have a non-NULL value?

Hello.
Yesterday David Crow posted a link to a wonderful article about using that stuff. Did you read it?

The article author solved some difficult problems in order to accomplish that task. MFC or Win32 doesn't really matter: you can easily adapt the MFC stuff to Win32 API. You know, MFC is a thin wrapper around it.

Just handle messages the way the article's author did, using your hook procedure and Win32 API.

Thanks. The weather today is really depressing (dark, rain). I needed this to cheer me up.
By the way, you seem to have some sort of keyboard malfunction:

Sadly, I think the keyboard is doing exactly what it was instructed to do.

How Can I evaluate an axpression in string ?
for example :
string x = "(6+9)/5-9";
string y = "Ln(10)+cos(30)-55";
How Can I evaluate that in visual studio ?
Is there a FREE parser that does these operations ?
I'm using vb 6

C++ isn't something like VB, where you can assign dump anything into any datatype. C++ requires you to know what you're doing.
If the result of your expression is a number, then assign it to a number and then 'store' it into the string with one of those string formatting functions.
int nVal = (6+9)/5-9;
TCHAR str[42];
_tprintf(str, _T("%d"), nVal);
You could alternatively write your own string class which does the conversion implicitly for you, by having the appropriate operators overloaded and enabling you to write statements of that sort where you assign an expression to a your string class object.

Really? Maybe they changed that in VB.NET. I haven't looked at VB in many years.

I know you have a secret fetish for VB6 (the main reason why you got into programming), but there's no need to support it here.

Is this a typo ? Are you using visual basic or visual C++ ? Because this is the C++ forum, so if it is a question for Visual Basic, then you should post in the VB forum.
Anyway, if you are using C++, take a look at this article[^]
