PN: Managed C++ and Unmanaged C++

Peter Nolan

Hi All,
I'm interested in the opinion of an expert or two on managed C++.net.

I've been writing cross platform C++ (win/unix) for some ETL tools I
use with clients. All the code is 'unmanaged' as I originally wrote
it in VC++ 6.

I've just completed my first managed code program. I also bought the
book VC++.NET 'Step by Step' Version 2003 and been reading that as
fast as I can. So all this 'managed code' and .net features of C++ are
new to me. I have written vb.net code and read a lot on vb.net and
ado.net.

On first reading it looks to me like:

1. VC++.NET is very closely tied to the win operating system.
2. It is not a trivial process to have unmanaged and managed code
inside the one large batch program.
3. If I was going to convert my code to C++.NET I would be re-writing
it, and then it will not work on unix.
So, it looks to me like the best thing to do is if I want to avail
myself of .net functions I should write code that is only intended to
run on windows and have all the code be 'managed code'. My other code
I should keep a separate copy to run on unix.

Or does someone out there know something about C++.net portability to
unix that I don't know about?

Thanks

At this time, I'd say your conclusions are basically sound, but see

http://msdn.microsoft.com/visualc/ho...a/default.aspx

at some future time, you'll likely be able to run "managed C++" on
non-Windows platforms.

Hello, in the last few days I've made my first few attempts at creating mixed C++ managed-unmanaged assemblies and looking aftwerwards with ILDASM at what is visible in those assemblies from a managed point-of-view I've noticed that: 1) for each managed and unmanaged C function (not C++ classes) I get a public managed static method (defined on a 'Global Functions' class) in the generated assembly with an export name of the form...

new to managed c++, interop questions

by: Eric Twietmeyer | last post by:

Hello, I'm starting to investigate cs, managed c++ and interoperating with a very large unmanaged code base. We are going to use Windows Forms (written in cs) to replace our old fashioned GUI. The guts will remain in unmanaged c++. So I need to write public managed c++ wrapper classes for the couple of interfaces the unmanaged stuff needs to expose for the GUI. Questions:

Managed Class Instantiating Unmanaged Class

by: Chris Kiechel | last post by:

I am writing a .NET Windows application and it needs to perform DDE calls to a legacy system. I created a C++ unmanaged class that performs the actual DDE connection and communication. However, I need .NET to instantiate this object and somehow allow the this object to callback to .NET. So, my question is: 1. How can a managed class instantiate and unmanaged class?

Hello, I am trying to create a dll that internally uses managed types but exposes a plain unmanaged interface. All the managed stuff shall be "wrapped out of sight". So that I would be able to use that dll from pure unmanaged code (for example inherit from classes in that dll). Is something like that possible. I heared something called ManWarp tried that approach. If it is possible, how can I do that. Maybe there is a small litttle

managed vs. unmanaged question

I understand the basics of what managed code offers and that you open yourself up to security issues if you allow unmanaged code. We already have a decent amount of VB6 code to include COM DLLs. If we put wrappers around some of our code or leave some "asis" what makes our existing production code 'evil' just because it is now considered 'unmanaged'? It may seem like a simple niave question, but the definitions for managed and...
