I just do not understand this error.
Am I misusing dynamic_cast ?
What I want to do is to have a single template construct
(with no optional argument) so that it works for whatever
T I want to use it with. Now, if that T happens to be some
subclass of a known base class (object, in this case), I
want to perform some extra stuff ...
I've read Faq#35, and the most natural solution would have

The following code is driving me so crazy, that I'm thinking it's a
"feature" or a..
....dare I say it... a BUG. I'm using VS 2003.
I've created a new value type (struct) called MyInt. MyInt has
all(?) the conversion routines necessary to convert from Int32 and string.
(see the listing at the end)
When I cast directly from a value of Int32 type, it works:

I get the following error:
Cannot implicitly convert type 'Factory.Stack.pArrayStack' to
'Factory.Stack.StackDefs.ImStack'
at compile time.
I thought perhaps there was a mismatch between the interface method
types and the actual implementation types, so I removed all methods
from both the interface and the implementation (pArrayStack ) but
still get the error. Here is the code with just one simple method
still declared and implemented.

I get 4 of those errors. in the same spot. I'll show my parent class,
child class, and my driver.
All that is suppose to happen is the user enters data and it uses
parent/child class to display it.
here is the 4 errors.

Hi there,
I'm having a bit of trouble using an HRASCONN object as a class member
variable inside my managed C++ class. When I call RasDial() and pass in the
address of my HRASCONN object, I get the following compiler error from Visual
C++ 2005:
error C2664: 'RasDialW' : cannot convert parameter 6 from

This is my first foray into writing a generic method and maybe I've
bitten off more than I can chew.
My intent is to have a generic method that accepts a value name and
that value will be returned from the source. My first attempt was as
follows; (please ignore that error handling is not present in this
example)
public T GetValue<T(string objName) {
T results;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
