RV: [omniORB] Managed code in Visual Studio .NET

[Javier Osa]

	Hello,

		I have avoided '_var' type variable problems using '_ptr' type variable
and when I need to free memory I use CORBA::release(...).

		I have discovered another problem. After of using _narrow(...) function I
used to call CORBA::is_nil(...), but now I can't call is_nill(...) function
because always returns 'true' when it isn't nill.

		Except these problems the rest works well. I use the same OmniORB DLLs
that I worked on VC6.

		Josu, Have you compiled the OmniORB DLL on VC7?
		Any problems?
		What version of OmniORB?

	Thanks...


	Xavier Osa

Hello,

I didn't success on the port from VC6 to VC7. I tried to use programs
compiled on VC7 with a VC6 compiled OmniORB dll,
it had lots of problems on the heap deallocation, some on the ' _var'
type variable release, some on memory corruption,
tracing omniORB  tcp packages showed errors, problems when more than 16K
were exchanged,  etc.
I didn't pay much attention to it,  as many sources errors were
identified. In order work out the problem  you should compile omniORB
first on VC7.
if you try in usual way you will  get a python.h include definition
error, so you have better compile python first with VC7. It would be
nice you could
have python compiled on managed code.
