Is it possible to pass an instance of a standard C++ class into managed
memory and use it (MC++/C#/VB/J#)? I guess I am still foggy on the whole
concept of Managed C++.

TIA,
Jeremy
 
You can provide a proxy managed class to wrap the native class. I've done a short example below. Also see
ms-help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.1033/vcmxspec/html/vcmg_overview.htm
in the VS help system.

class UnManaged{
public:
int data;
UnManaged(int d = 0) : data(d) {
}
};

__gc class Managed{
public:
UnManaged& um;
Managed() : um(*new UnManaged){
}
~Managed(){
delete &um;
}
__property int get_data(){
return um.data;
}
__property void set_data(int d){
um.data = d;
}
};

int _tmain()
{
Managed* m = new Managed;
m->data = 23;
Console::WriteLine(m->data.ToString());
}
