We have a lot of code which runs fine under VC++ 6.0. We have to move to
.NET becasue one of the librairies uses .NET classes.
Does every library(including those which do not use .NET classes)  have  to
be recompiled with /clr option?.

I'm a MS/.NET newbie, diving right into CLR interop.  I've worked
through the various issues foreign to me as a UNIX guy:  multiple heap
issues because I was linking to different CRT instances (ugh), calling
conventions, marshalling, etc.  I'm stumped on one issue, though.

Hi;
I want to create a function point.With is point I can call the member
function in a class. The Sample Code just like:
__gc struct NodeMapItem

   When I upgrade my old vc6 application to VS.NET2003, I always get a
linker error, I had fixed some compiling error,
the error message, error LNK2019:
MultiWME error LNK2019: ?????????????????? "__declspec(dllimport) protected:

I compiled the hello world program, as specified in the current C++/CLI
draft (version 1.5), by using Visual C++ 2005 Express Beta 1:
int main()

Sorry for the long post, it's a bit epic (and sums up the last 10 hours of
my life, apart from my car's gearbox melting).
We've got a mixed C++ assembly that's exhibiting odd behaviour when the
/OPT:REF (remove unreferenced data) linker option is set. We first noticed

I have a question here regarding implementing Binary Tree.
I understand that Binary Tree can be implemented in one of
the following methods:
1)using nodes with pointers to two children.

I wonder what are the possible ways to implement a Map
in C++?
Among these methods, which is the best one and why?
Thank you very much in advance.

I've created a HANDLE[] in a managed class:
pHandle = new HANDLE[2];
where pHandle is HANDLE* defined in my __gc class
Is this an unamanged or a managed pointer? I would have thought it would be

can somebody tell me how to convert the date from a Paradox .DB to human
readable format?
I need to write a tool to convert the 4 Bytes representing the date to a
human readable format.

I wondering whether we can mix VC++ and .NET libs. we are in the process of
porting our VC6 code to VC 2003 .NET but would like to know whether I need to
port  all thirdparty tools to .NET immediately.

I am trying to compile old 16-bit C code in VC++2.0. I am running into errors
using the header file graph.h. This is a microsoft file that uses the
keywords '__far' and '__huge'. Is there a way to replace these keywords or
the entire header file itself for 32 -bit applications?

I'm reading Microsoft Visual C++ .NET Step by Step, Version 2003 and I found
a sentence it says :
"you can't have pointers to managed types as members of a __gc class.".
Why ?

Where it2 is a vector<Body3d>::const_iterator
How come I can't do this
float xd = (*it2).getXpos();
(Which fails with a "error C2662: 'Body3d::getXpos' : cannot convert 'this'

hello, i have an old library i need to port to .net. the old library is written in visual c++ 6.0 and uses templated classes.
if i compile the library (after having gone through the conversion wizard), i get errors with the definitions of the templated classes. below are some ...
