I am writing a .NET Windows application and it needs to
perform DDE calls to a legacy system. I created a C++
unmanaged class that performs the actual DDE connection
and communication. However, I need .NET to instantiate
this object and somehow allow the this object to callback
to .NET. So, my question is:
1. How can a managed class instantiate and unmanaged

We use StackWalk(StackWalk64) from dbghelp.dll to walk our
callstacksas needed, using the various Sym* methods
(SymGetSymFromAddr, SymGetLineFromAddr) to resolve source file,
function name, and source line number for each frame. This works fine
for unmanaged code, but when we have a call stack that goes into or
through some managed code, we cannot resolve any info for the managed
frames - we can however, get all the information for the...

Hi, I am quite new about .NET framework and now working a research
project using VC++.net. I created a c++.net console application and
began to develop my own classes and algorithms with standard C++
language. Sometimes "template" feature is also used.
But recently, our project manager emphasized that our codes should
base on the .NET platform. I have checked the "platform" contribution
in the "configuration manager" of build menu. Win32...

My understanding is that when I re-compile a existing MFC application with
the /clr switch, that the code generated is managed(with some exceptions)
but that the data isn't, i.e. not garbage collected. I also noticed that
when replaced some of the existing MFC dialogs with managed winforms that
everything is still running in the same app domain.( No context change) So
my question is this, what are the performance differences in using...

Hi All
I have a VC++ 2005 MFC application with all classes defined as
unmanaged classes. I want to write my application data in xml format.
Since ADO.NET has buit in functions available for this, I want to use
it. Is it possible to call Managed class functions from Unmanaged
class? How to do it?
I did something like this.
I declared a managed class (in C++ CLI) called as MyManagedClass whose

Hi,
I have a rather interesting problem. I have a unmanged c++ class
which needs to communicate information to managed c++ via callbacks,
with a layer of c# on top of the managed c++ ultimatley retreiving the
data. Presently all of the c++ code is still in .NET 1.1, so we're
using a _nogc bridge class wrapped in a _gc c++ class in order to
facilitate this interop.
But we've converted everything not c++ to .NET 2.0 and would love to

Hi,
I have an existing VC 6 MFC application which communicates asynchronly with
a VC 2005 managed code dll.
I use an unmanaged base class with virtual functions to access methods in
the MFC application.
Furthermore, I use a pointer to an unmanaged function to jump back into the
managed dll.
The managed part is basically a remoting enhancement which asynchronly

Hello,
was wondering of how to dispose of managed resources?
or referencing every member of a class to null will release
resources...?
