Then you'll need a COM dll.
I recommend that you read about ATL on MSDN, as it is the simplest way of creating COM dlls without having to understand all the workings. The wizards pretty much do it all for you.

hi geeks
i'm gonna invoke a dll handle which hosted in another process (i mean in another memory space ) from my process .how it could be possible .
matter of fact i'm wondering if it's possible to get a dll handle in cross process condition .
give any clue you know.
thanks in advance .

Invoke what ?
What handle ?
...cmk

if u'r talking about hmodule handle retrieved by loadlibrary, then this handle will be invalid in context of another process. this handle is living only in virtual memory space of current process.

Next semester, I'm going to take Unix programming,
and I'm excited about it. However, I wonder, if
Unix supports C++? Or it just supports C?
By the way, what is the main difference between
Linux and Unix? Can I apply technique I learned
from Unix to Linux?
Thanks

C++ without virtual functions is not OO. Programming with classes but without dynamic binding is called "object based", but not "object oriented".

you can program c++ in unix and gain it's power.
download and make gcc 3.3 or higher version for unix environment.

The difference between UNIX® and Linux is that Linux isn't certified to use the UNIX® trademark. Both are based on the Single Unix® Specification standard (ISO/IEC 9945).

No!
Unix is an operating system just like Linux, MS Windows, DOS and CPM (ancient system), and others. The operating system is only important if you are writting code specificaly for that operating system. No matter what system you are programming for, most of the code (if not all) should work. If you are running the compler on that system, then you are probubly creating a program that will only run on that system.
Operating systems (as a general rule) do not support programming languages, but complires do.
Example: The Visual C++ compiler is supposed to beable to compile for both Windows and Macantohsh. That is if you are devloping the program on an MS Windows system and compile it for Macantohsh, you can not run the program.

Hi John,
Thanks for your reply. I have another question: In your
profile, you said that you are a Software Engineer. I wonder
what is the difference between Software Engineer and Programmer?
In my University, I have an option to focus on Software engineering,
however, my final degree will still be Computer Science. I wonder
what takes to be a Software Engineer? When I graduate with a BS
in Computer Science, will I be called a programmer or software
engineer?
Thanks

'Programmer' is the broad, general term for a person who writes computer programs. There is no implied level of training or expertise. A 13 year-old kid writing script and a $100,000/year employee writing C++ for embedded systems are both programmers.
'Software engineer' is often used as a job title. A software engineer is a programmer who applies engineering practices and principles when they develop software. These engineering skills require either a university education or several years working experience to acquire. The 13 year-old kid writing script is definitely not a software engineer. The $100,000/year employee is a software engineer.
Your degree in computer science will make you a programmer. Generally, graduates with CS degrees apply for software engineering jobs. Those same jobs may be listed with a job title of 'programmer'.

More specifically, if you study Computer Science in a university, and get a degree on that, then you, like said, become a 'programmer'.
In my country, there are schools available which educate on the B.Sc level of degrees. The line I'm on is called "Software engineering". Thus, when I graduate from this school, I get a B.Sc, and can call myself a "Software Engineer". Just like someone graduating from our school on the architectural line would call themselves "Architects" or "Building engineers".
The idea is that "an engineer" is a qualification. M.Sc with CS as primary is called a degree. Mostly a wordly issue, though, as both CS degree dudes and engineers do same jobs

My title is Software Engineer! What I am is a programmer++ (without a B.D. or an M.D., hence the ++)! The difference between a programmer and an engineer is fairly simple: A programmer is someone who knows the language well enough to solve the problem(s) given them, An engineer (normaly a B.D. OR an M.D.) is someone who can figures out what the problems are (or well be) before they give the problem to the programmer(s).
That does not mean the engineer is (or was) not a programmer, but it does mean that he may (or may not) know what he/she is talking about.
Enough of that!
What it all amounts to is that an engineer makes more money than a programmer!
As for your question: If you have a B.S. degree, then you are a software egineer.
Just remeber that because you have the degree, that does not mean you know more than the programmer doing the job (listen and learn).
Note: I am titled an egineer, because I have never been given a problem that I could not solve.

Hello
I am Aqueel. Please tell me how can i call an event or a function when mouse pointer is rolled over a button.

A button is a control. A control is a window. When the mouse moves over a window's non-client area, a WM_NCMOUSEMOVE is posted. When the mouse moves over a window's client area, a WM_MOUSEMOVE is posted.
To detect when a mouse enters/leaves your button's area, answer to the first WM_MOUSEMOVE message, and call TrackMouseEvent, specifying that you wish to know when the mouse leaves the window's client area (WM_MOUSELEAVE). When the mouse does this, the tracking is automatically cancelled. Between the first WM_MOUSEMOVE and the WM_MOUSELEAVE, the mouse is hovering over the button. To prevent calling TrackMouseEvent multiple times, use a boolean variable that you set in WM_MOUSEMOVE and clear in WM_MOUSELEAVE.
Hope this helps. You should see MSDN for TRACKMOUSEEVENT structure. This documentation will tell you how you must fill the structure in order to track for WM_MOUSELEAVE messages.

Can anyone tell me if it's possible to link a file to a email via a hyperlink control?
I'm writing a utility for some of our customers and would like to include a link for them to click on that sends an email with a data file back to us.
I'm basically looking for the syntax to use if it exists. For example, there is also a link for feature requests, and the syntax I'm using for that is:
mailto:PaulBelikian@SomeCompay.com?subject=feature Request
is there another keyword I can use to attach a file to the email also? something like:
mailto:PaulBelikian@SomeCompay.com?subject=Data file upload?Attachment=C:\CustomerFile.XML
Any help would be appreciated.

I haven't seen anything in the mailto syntax that supports that - Attachments are usually MIME encoded at part of the body and not the header. RFC-2368[^] does describe a "body" section, but it is plain-text, follows the keyword and most non alpha numeric characters must be encoded (i.e. space is represented by %20)

Well I've not used the pro version, only standard which is fine. I'd try posting on BCGSofts support forum[^] and see if you can get help there

I have always used Win32.hlp in my work, but with the emergence of WinXP I think I am missing a lot of the system functionality. Where can I get (for free, of course) the latest version of Win32.hlp that covers XP?

If you want to use the newer XP API's, then you are probably best off downloading the latest platform sdk. Download here[^]
This will give you the latest documentation and the libraries and headers needed for the compiler.

hello buddy,
i think there is no diffrence they oare same thing.
and about use,they are used for dynamically memory providing.
for eg look here
char *ch;
now if you want to allocate memory to it
use ch=new char[100];
and for freeing memory
delete []ch;
if you really want more message me bye and take care

"new operator" is used when refering to allocating new object.
i.e. char *bob = new bob [20];
"operator new" is part of the syntax used to specialize the "new operator".
They are both talking about the same thing for the most part.
