I'm developing a game in win32 c++ DirectX.
On my graphic game window I have a picture of a 'close' button. When I click on it I want it to to the same as clicking the 'X' button.
But although I tried several things:
<br />
::SendMessage(hWnd, WM_CLOSE, NULL, NULL);
::SendMessage(hWnd, WM_DESTROY, NULL, NULL);
<br />
DestroyWindow(hWnd);
I get strange bugs that won't happen when I click 'X'.

Thank you very much.
It seems like all crazy bugs are gone.

Don't do that! That doesn't destroy a window

Thanks.
I Really shouldn't post
::SendMessage(hWnd, WM_DESTROY, NULL, NULL);
as a real candidate.
I was pretty desperate when I posted that message...

Hello
I am looking for a graphing library simalar in look/functionality to MSAGL (previously called GLEE, see:
http://research.microsoft.com/research/msagl/[^]) for a project being developed in c++.
The problem with using MSAGL/GLEE is that it is written in c# for .net and I require a native c++ library which i can link into an existing project under development (build enviroment is borland turbo c++).
Can anybody recomend anything?
Many thanks in advance

on top of my head, maybe GraphViz can do that ?

Hello All,
Is there any way to restricting a class to be inherited? I dont want any one to inherit my class. I feel this can be possible only by making the constructor in private. Is there any other way to do this?
Regards

I think there is no way (other to switch to .NET programming).
But do you really need such a feature?

A private constructor is the only way that I know of.

Yep.
Only restricting access to the members using the private keyword will cause an impediment to use it as base classe because the private members of the base class are unavailable in the derivates.
There's not a sealed attribute in C++.

1. Private constructor to restrict inheritance.
2. Pure virtual member function to restrict object instantiation.
That's all I know.

You have the technical answers but are you sure you are applying this where needed?

I guess that the OP is making a DLL or something which exports classes ...

So exported classes should not be inheritable? I never knew that.

Ah, now I understand, it's the developers preference that is used as criteria to determine that a class should not be inheritable. I never knew that.

"Yes, but why do you want to?"
Thank you, sometimes it's like talking into space, devoid of logic and reason around here.
