How to handle resources in mixed managed/unmanaged C++ projects?

I have former VC++ 6.0 application which was ported to .NET.
Now we continue to develop this app under VS.NET. The app
now contains both managed and unmanaged classes.

Now I have a problem with usage of resources in managed classes.
For example I want to display warning message and want to load
that warning message from the resource file. The problem is that
in this mixed managed/unmanaged project I don't have pure managed
resources (like for example in C#) and I can't use ResourceManager
to get strings from resources.

The project still has old unmanaged resource file (.rc)
So the only option I see is the following:

// Load from unmanaged resource file
CString strMsg ;
strMsg.LoadString(IDS_READ_PROGRAM_STATUS ) ;

// Convert to managed string
String* strMsgManaged = Marshal::PtrToStringAnsi(static_cast<IntPtr>(strMsg
) ) ;

This approach looks very ugly to me.

So here are my questions:

Is there simple way to load string from unmanaged resource file to managed
String object?

What are the best practices to handle resources in mixed managed/unmanaged
C++ projects?

Thanks

Yes.

Why not just do:

String *strMsgManaged = strMsg;

?

Agree,
String *strMsgManaged = strMsg;
looks much better, but the main question how to load strings from unmanaged
resource file to managed String object remained unanswered ...
 
Hi Steve!

This is exactly what you are doing, isn´t it?

What answer do you expect?

In managed world you can use "ResourceManager" to load strings from
managed-resources (resx).
In unmanaged world you can use LoadString...

There is no world between them...
