I personally find it works well. It's the most useful (to me) thing
that's been added to Visual C++, well, ever.
The Managed Extensions were kind of a "disaster" with
confusing syntax and lack of some useful keywords, but
the new C++ syntax is pretty nice to use.
I guess for C# programmers, all of C++ is a disaster

I'm using Microsoft Visual C++ 6.0.
I have the following codes in my program:
int x;<br />
cout<<"Enter a number: ";<br />
cin>>x;<br />
double Num[x];
The following errors are occured:
1. error C2057: expected constant expression
2. error C2466: cannot allocate an array of constant size 0
3. error C2133: 'Num' : unknown size
How to solve my problem?
Please do not tell me to enter something like "int x=100" or "int Num[100]". I want to the user of my program set the size of the array.
Any reply will be appreciated.

Then you must be in the wrong forum ( VC7 was the first to support managed C++ ). Try the visual c++ forum.
The answer is that you need to dynamically allocate via a pointer if you don't know the array size at compile time. But, next time, this is the wrong forum.

I need the c++ program wich can calculate the centroid of the curve with the Reaiman Sum.

Using managed C++?
If not, please post your question on the Visual C++/MFC[^] board.
Have this info? Riemann Sum[^]

Try searching this site for articles about services and accessing
the registry....I bet there's lots of them 
Reference material:
Services[^]
Registry[^]
Since you've posted on the managed C++ board, I'll assume you're
using managed C++. In that case, there's an appwizard in visual studio
that will create a managed service application for you.

I'm not sure what you mean by that...
Anyway, type "windows service" into the search box at the top of this page.
When you get the list of hits, you can refine your search to just C++-related articles.
I just tried it....there was many articles on creating Windows Services there.
Most articles have source code you can download.

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
Buck

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.
