Greeting,
My platform is Solaris 2.8. My question is that if there is a simple way to
put a class object in share memory, so that multiple process can use this
object.
Thanks in advance!

Hi folks.
So I'm in the middle of porting a large (previously COM-based) imaging
library to .Net. The clients of this library are VB programmers within the
company I work for. Their code will be getting ported to .Net at some point
in the near future too.
In the .Net world, many of my objects are forced to implement the
IDisposable+Finalizer pattern because they hold onto unmanaged resources or
represent resources where deterministic...

im allocating an object that is a wrapper of unmanaged code.
how can i pin that object in memory ,so the gc will not move it.
the reason is some other data members of the object,are sent to unmanaged
code.

I need to pass the address of a variableto some win32 API functions like
RTLMoveMemory
I noticed some weird behavior when pinning objects and using the handle's
pointer to write data to the memory location.
it seems as if after pinning an object the memory and the object are not
updated at the same time anymore

Hi,
please pardon me if I sound stupid. I want to check the status of the
GChandle to see if a previous call to Alloc is successful, or whether it
has been called before hand, before I call the Free function. I tried
the following code,
GCHandle gch;
gch=GCHandle::Alloc(Mydelegate); <== How do I check if this is successful?
gch.Free();

Hi all,
I want to understand more about how the pinvoke pinning process works.
I'm writing some code that calls DeviceIoControl.
DeviceIoControl provides a generic interface to device drivers.
Its signature is deliberately open-ended so that it can be highly generic.
Refer SDK for more.

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

I use a method for threading that instantiates an object that is a wrapper to
a DLL (written in C).
The wrapper class is passed a byte array, and then does
GCHandle handle = GCHandle.Alloc(buffer, GCHandleType.Pinned);
IntPtr ptr = (IntPtr)(handle.AddrOfPinnedObject().ToInt32() +
buffer.Length-1);
It passes ptr to the DLL function FunctionX().
