I discovered that you cannot use #pragma unmanaged for a member function of a managed class, even though the member function uses only unmanaged calls. Thus I have concluded that you can use #pragma unmanaged only for unmanaged global functions or for unmanaged classes. But then, what's the bloody point, since unmanaged code will get compiled to native code anyway!

Thats the whole point, you can call the x86 code from managed code 
#pragma managed
public __gc class MyClass
{
void DoLotsOfUnmanagedThings()
{
unmanagedCall();
}
};
#pragma unmanaged
void unmanagedCall()
{

Well, when it sees a fuilly unmanaged function, why doesn't it auto-apply #pragma unmanaged to that block?

1. Managed Code - Code that compiles into IL (atleast in the first version of CLR in the next version it would be possible to have IL unmanaged functions)
2. Unmanaged Code - Code that compiles into native processor's instructions
So you see there is nothing called an unmanaged function before anything gets compiled.
It is perfectly legal to have global functions in managed code. ILASM can create and use it( may be VB.NET).

That's what I thought too, till it disallowed me from using the #pragma unmanaged directive to a function

If i write a program in UNMANAGED VC++ 7.0 using ATL 7.0 and\or MFC 7.0, do I have to install the .Net framework or can I just supply the required ATL\MFC DLL's to the users machine?
Is installing the framework just for Microsoft's CLR?
|

If its unmanaged you don't need the framework; only when you cross into managed code do you need the framework on the users machine.

So I guess if I am using 'normal' and Managed code I just have to install the framework?
|

Yes. If your application uses both; the framework has to be installed.
Something that just came to mind though. If you have it set so it can *optionally* load the managed code (ie it loads the managed code on demand and doesn't have anything about the managed code compiled aside from a GUID), then the framework could possibly be an option for the client as well... But if they decide to use it they will need the framework.

BTW, hopefully this time next year or the year after we can assume that many will have the framework installed so the fact there is a 20MB download won't be as much of an issue.

End users, using windows update?!?!?! That'll be the day.... 
The problem with windows security problems isn't the problems its that stupid users don't patch their computers up to get rid of the problems.
This is non-existant in the *nix community because almost everyone who uses it knows about security problems and patches them ASAP.

Ollie the use of the word UNMANAGED implies deviant behavior, Many of us are calling it 'normal' programming now.

Hello, I've been working for a couple of years with VC++; a few months ago I started to see information about Managed C++ but actually I don't know nothing at all about it. I've been searching recently for some introductory articles or explanations but I've been not able to find it.
Does anyone know where could I find something like that? In the board everybody seems to be already deeply inside the world of MC++, but I need something more basic!!
Thanx in advance
Jaims

You could buy a book about MC++? Or you can read the msdn.microsoft.com they have a pretty good introduction about .net, you can also look in http://www.microsoft.com/visualc/
The easiest way is to jump in the pool. Install Visual C++ .NET and create a project.
