Intellisense in header files

Question

I just right now "migrated" from C# to C++/CLR. First I was annoyed, that I had to write all class' declarations twice (into .h and .cpp). Then I figured out, that I could place the code also into the h-files - it compiles at least. Well, I deleted all cpp's of my classes and now I realized, VS won't give me any Intellisense when I work on my h-files.

I guess I should not place my code in the hfiles (the code won't be reused in other projects for sure), but I find it terrible to adjust all method declarations at two places... Plus I have to switch back and forth to see what modifier my method etc. and it is not nicely all in one place like in C# (with it's pros and cons).

I'm sorry this is a newbie question, but I just wanted to make sure that there isn't any possibility to enable intellisense for hfiles. Or at least to learn, that I am completely on the wrong path...

Thanks, David

Your .h files should contain declarations. your .cpp files, definitions.

Here's an example:

b.h

#ifndef B_H    
#define B_H

    class B
    {
      public:
         int foo();
         void Set(int x);

      private
         int data_;
    };

#endif

b.cpp

#include <stream>
#include "b.h"

int B::foo()
{
   std::cout << "data value " << data_;
   return data_;
}

void B::Set(int x)
{
   data_ = x;
}

Any place you'll use objects of type B, you #include b.h. The implementation is only in b.cpp If you do this, intellisense should work

You're blowing intellisense out of the water because code for every class is being inlined into every implementation file, and that's just more data than Intellisense can parse reliably. It starts failing due to timeouts.

I know you said it's annoying, but you have to put the class in twice -- that's how C++ works. If you want it to behave like C#, use C#. It's a better language for the .NET platform anyway.
