How can I prevent a class from being inherited?
My idea is to declare the constructor of the base class to be prviate. Is it correct?
For example
class A
{
private:
A() {};
public:
~A() {};
}
class B : public A
{
public:
B() {};
~B() {};
}
int main()
{
B b;
return 0;
}
As I compile the program, error C2248 happen. Is it all right?
Is there any good idea of preventing a class from being inherited?
many thanks.

Have a look at sealed keyword.

Excuse me, I can't find any subjects I want in your articles.
Can you give me a link to it or say in more details?
thanks.

I didn't mean my articles, it's just my signature. Just look up sealed keyword.

oh, I see. I have found the topic through keyword research.
Thank you very much indeed.

Hi, I'm using Visual Studio 2005 C++/CLI and I wanted to bring up a properties page when an object/control is right-clicked on. It seems that I can have all kinds of general mouse events but how do I determine if the left button was clicked (pressed down, let up, etc.) or the right button was clicked? And what about three button mice and mice with thumb-wheels?
Thanks

Handle the MouseDown event and check the Button property of MouseEventArgs parameter that is received by the eventhandler

Thanks, works great, lasts a long time.

By definition, this means you're not using C++/CLI and are in the wrong forum. The Visual C++ forum is the closest we've got to Borland.

Just more proof that the forums aren't clearly/appropriately marked
"Visual C++" should be called "Native/Unmanaged C/C++"
and this forum should be called "Managed C++ and C++/CLI"

And of course I just noticed this forum says "(Managed)" at the top of its name. :/

I know this sounds like a stupid question but i can't seem to get a for each loop to compile correctly.
I tried...
for each (IpAddress ^addr in ipAddresses) {
}
and...
IpAddress^ addr = nullptr
for each (addr in ipAddresses) {
}
but none of them compile. I know i could do a for loop but i would rather just do a for each. I searched but i cant seem to find anyone else having this problem. Thanks alot for any help
here are some of the errors:
Error 1 error C2143: syntax error : missing 'in' before '^'
Error 2 error C2065: 'addr' : undeclared identifier
Error 3 error C3192: syntax error : '^' is not a prefix operator (did you mean '*'?)

And what are the other errors? Sometimes some errors are caused because of the errors that occur before them. I guess these are errors for the first case. Your code should look like this:
<br />
foreach (IpAddress^ addr in ipAddresses)<br />
{<br />
<br />
}

hey Giorgi thanks for your reply.
these are some of the errors i get.
Error 1 error C2143: syntax error : missing 'in' before '^'
Error 2 error C2065: 'addr' : undeclared identifier
Error 3 error C3192: syntax error : '^' is not a prefix operator (did you mean '*'?)
array<IPAddress^>^ ipAddresses = Dns::GetHostAddresses(Dns::GetHostName());
for each (IpAddress ^addr in ipAddresses) {
}
i don't think it is any other part of the code that is failing because as soon as i comment the for each loop it compiles fine. Thanks,

can anyone code the VRP problem using genetic alogrithms in c++.
i need that to be done as a report along with code to submit for my exam.
kindly help me in this work

Really....don't cross post.
That means don't post the same question on several discussion boards.
Pick the one that best fits your topic.
Also, this isn't a "we do your homework" site. I bet if you offer lots of money you'll
get a better response.
If you're unable to offer large sums of cash, then show us a little of what you've already
done, along with a description of specific problems you're having, and maybe we'll try to help.
If you choose this route, please post on the correct discussion board.
Cheers,
Mark

Hi all,
I am using ipl98 library version 2.20 and I was compile it successful. However, I can only use the static library is created by VC++.net (It can run ok with the example in ipl98 library project.) The dynamic library cannot use it to run the example.
About Borland C++, I also compile successfully but the dynamic library cannot do with the example. After that I compile it to create the static library, this is not successful, the error: library too large, please restart with library page size 32.
My purpose is using ipl98 library version 2.20 in the Borland C++. However, I spent a lot of time but until now I also cannot use it in the Borland C++. If you have any advices, any ideas, or any instructions please show me!
Can we use the static library created by VC++.net to transition dynamic library? Or Can we use the static library in Borland C++? Or you have another ways to solve it.
I hope I will get your feedback as soon as possible.
Best regards!
nothing

Unless this version of Borland supports Microsoft .NET libraries, and they are used by this dll, you're in the wrong forum. The Visual C++ forum is the place for non .NET C++ questions, even then, I doubt many people here use Borland.
