Non-copyable KnuthUniformRng

[Slava Mazur-2]

The following declaration in KnuthUniformRng effectively makes this class non-copyable:

std::vector<double>::const_iterator ranf_arr_ptr, _arr_sentinel;

However, KnuthUniformRng is not declared as such. As a result, any attempt to call next() of a copy of any temporal instance of KnuthUniformRng ends up in a crash (let me know if further elaboration is needed). I don't believe this is an intended design. There are two possible ways to fix: either to keep indices instead of const_iterator, or to implement a copy constructor and an assignment operator. I personally prefer the former, but can provide any fix community will choose.

Best,

Slava Mazur

You're right.  Indices instead of iterators are fine with me.

Thanks,

On the recent addition of solution files for VC++ 10, has anyone
found a simple way to add additional include directories
and libs? This used to be done using Tools/ Options
/ Projects and Solutions / VC++ Directories, and in
this way the settings would apply to all projects in a solution.

But this feature has been deprecated in VC++ 10, and instead
user property sheets are supposed to be used, but I don't
see how to do this so that it applies to all projects in
a solution (globally).

This can be done on a project-by-project basis using
Properties / Configuration Properties / VC++ Directories,
but this would have do be done for each project, and
for each configuration (Debug, Release, x32, x64, etc.).
Very tedious.

A solution that works for the Express edition is of
course preferred.

Thanks,
Dominick

Dominick,

>> But this feature has been deprecated in VC++ 10, and instead user
property sheets are supposed to be used, but I don't see how to do this so
that it applies to all projects in a solution (globally).

I found several links about, like
http://efreedom.com/Question/1-2629421/Use-Boost-Visual-Studio-2010 and
http://blogs.msdn.com/b/vsproject/archive/2009/07/07/vc-directories.aspx.
However, I didn't find anything like Microsoft.Cpp.<Platform>.user or
Microsoft.Cpp.Win32.user in VC++ Express 2010 so I opened C:\Users\<your
login>\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props
and add the below

I appreciate if someone sends a screenshot of such
(Microsoft.Cpp.<Platform>.user or Microsoft.Cpp.Win32.user) options in the
GUI once they are supposed to be the right way to setup includes globally.

<PropertyGroup>
        <IncludePath>C:\Users\<your
login>\Development\include\boost-1_44;$(IncludePath)</IncludePath>
</PropertyGroup>

Thanks a lot,

Yes, I had to go through the same ordeal.  After much searching, what I
did was:
- select View/Property Manager from the IDE menu;
- open the subtree for any project and configuration;
- you'll find a Microsoft.Cpp.Win32.User property page inside.
- right-click and select Properties.  Inside the dialog there's the good
old "VC++ directories" option.

The trick is that this particular page is shared, so when you edit it in
one project/configuration they all should see it (I don't remember if I
restarted the IDE after modifying it, though.)
