I've been talking to someone about VS 2010 and we seems to be in a fog and i would like to clarify that.

That person told me that producing C++ code in VS2010 would automatically be managed.  

Can we still produce C++ unmanaged code in VS2010 and how?  
I've seen several C++ projects type but it's not clear for me.

thanks

Basically - RUBBISH, they don't know what they are talking about OR just misunderstood you.


For an existing project it will be unmanaged unless you deliberately change settings to make it managed.

For a new project just select the options (project template) that don't require managed code

Thx Andy, but could you be more specific?

What kind of project template allow me to start a project for unmanaged code?

What are the settings i must check in the project to make an existing project unmanaged?

thanks

>>>"ng C++ code in VS2010 would automatically be managed"

this is just not possible.

You need to understand the concepts first. Take a look at this link. It might be a bit old but should give you an idea.

See attached picture for possibles, you might have even more available (could depend on the version of VS 2010 you have)

If it was unmanaged before conversion to VS2010 format then it is still unmanaged - nothing you need to do.

CLR means common runtime support.
If anything is selected then it will be adding support for .NET (=managed) code.

Thanks for your answer Andy.

@trinitro: thanks for the link, i'll have to read this for sure because i need to understand this subject a lot.  I want to develop some VNC-Like Server application, and i've done some tests yesterday in C# to do some BitBlt.

In my test, i've copied the whole screen, pieces by pieces (10x10 pixels block, i know that it's extreme... usually it would be something more like 50x50 or 100x100).  On my i7-950 with a kick ass graphic card, it took a fraction of second to copy the whole screen (1920x1200 resolution).  On an AMD Phenom II X6 1100T (which is still a pretty good computer), it took over 3 minutes for a smaller resolution.  

So i need to understand if writting some functions in C++ Unmanaged for the core job (to avoid slow pinvokes), mixed with C#, would do the job.

Should do - one can call an unmanaged dll from managed code.  One could also do a mixed mode dll (mixes both managed and unmanaged code) in C++.  I think that is referred to as IJY - It Just Works.  Your C# app could then use the C++.net part which talks internally to the unmanaged C++ section.
