Board index » Visual Studio » Where to learn Managed C++.NET?

Visual Studio223
Hi there,



I am wondering where i can learn Managed C++.NET. I had

check out the msdn C++.NET specs. Very hard to learn.



I had no money to buy books.



And there are far too little tutorials on this area in

google.



Only see some like Hello World, Sortting algorithm (mostly

consoles).



I had no much knowledge in c++ so i can't be looking at

application and learn it.



Any help please?



Thanks.

Goto www.codeguru.com



Scroll to the bottom for thier columns and regular features section. Kate

Gregory has a regular column on managed c++ .NET programming starting from

the basics and progressing, should help you. Though you should probably have

an good understanding of C++. Also if you are going to do managed code, C#

may be a better choice of languages, unless you are a rather advanced C++

programmer and plan on mixing managed and unmanaged C++ code inline there is

no real point to doing managed C++ IMHO. Anyhow hope it helps, good luck.

I would suggest looking into C#. Its more efficient as far as writting

the code and its all managed nicely. I wrote a OpenGL wrapper

for .net in c# and had a great time.



Of course the execution time between c# and c++ code isnt the same

but thats not always an issue.

Dear everyone,



Thanks for the reply. The reason why i want to learn

c++.net is bcs i want to write managed wrapper for

existing c++ static libraries. That is why?



I know c# .. well okay for me to code something.



Anyway thanks. yeah i am looking into his articles. Is

there any more?



:)



Thanks.

You can use c# to write a managed wrapper around your native c++. Its all in

the interop namespaces.



Enjoy!!

P.S.



Check out www.thecodeproject.com I believe there are a few articles with

full sample code that do what you want. THis is also one of the most

valuable sites for almost everything you could want to do in .NET.

You can? You sure?



I am suppose to convert static libs (with .h or .lib) to

managed so later i can use C# with it. I don't think COM

interop can do this?



Not sure.. i base on 2 person.. 1 intel programmer which

did this type of stuff and 1 more is the programmer of a

game engine.



You sure c# can???

Well I think that there is something being lost in the translation here.



But you can write a C# DLL that wraps your native C++ DLL, so you would use

your C# dll to actually call your C++.



However if you were going to fully convert you native c++ to some managed

form it would probably be a better idea to go with that for optimization

purposes.



As to am I sure, yes I am I have a huge ASP.NET app that calls all my native

C++ DLLs using via C# with DLLImport and marshaling stuff.



So I have a native C++ DLL. I create a C# application and then I import the

DLL.

here is the import syntax.



[DllImport("c:\\development\\cpp\\teststuff\\release\\VIsAlive.dll",

EntryPoint = "DeleteResults")]

unsafe public static extern void DeleteResults(IntPtr pResults);



After doing that I can call my DeleteResults function from my C#, just need

to make sure the unsae option is set to true in the settings.



-Enjoy!!

The problem is i do not have any native dlls. It is just

static libs with *.lib. I think so! I can't remember. Coz

i am not with my dev PCs.



Thanks for the reply.

The documentation that comes with .NET is massive.

If you take the time to sit down and research info

on how to wrap functions from external modules,

im sure you'll find more info then you need.
