i want to use the << operator defined for ostream with an object that
itself knows nothing of the operator, but is castable to ostream&. it
seems that C++ doesn't do implicit casts before invoking a custom
operator.
i've tested with visual c++ 7 and the comeau online compilers, both
required an explicit cast. is there a way to hint the...

Hi,
is it possible to define an implicit user-defined type conversion
operator for enums?
I'd like to convert my enum to an int without an explicit cast, e.g.
something like this:
------
public enum MyEnum : int

hi,
Let's suppose I've got 2 classes: MyClass and MyClassColl (coll is inherited
from ArrayList, for instance). But, when I invoke GetXXX or something
returning object, I receive an object - not instance of MyClass. I've tried
with implicit conversions - not working.
Is there any way to inherit some collection that will have instances of...

Interesting note, the code below as is will attempt to cast what is clearly
indicated as a string into a double. This is becuase the use of + as a
concatenation operator. The error message generated is included with the
code. Use & instead and it works.
Dim pstrSend As String = ""
'ActionCode 1 and 2 are type BYTE, Msg is a byVal...

Hi All,
Please excuse me, but the bulk of my post will be a code post. It
describes some weirdness with regards to the implicit casting operator.
The crux of the problem is this:
I want to set a property on a class that takes an interface instance.
I have a class that can cast implicit to a class that impliments said
interface,
but the...

I have an Angle class that I store angles in. It's basically just a
bunch of fancy functions for manipulating a double. It has implicit
casts for converting to/from double. Due to the project structure and
where it stores the preferred SI units for display, I wanted to have
the TypeConverter in a different project that has no reference to the...

I have checked the FAQ: http://c-faq.com/malloc/mallocnocast.html
FAQ discusses a special case when programmer has forgotten to do
#include <stdlib.h>. I am including this header and I am not doing any
explicit cast:
#include <stdlib.h>

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. ...
