C# 2.0 question about generic type parameter constructor-constraint

What if I have some special constructors and do not have a default
constructor. It seems to be very useful when I do not want to forget to
initialize some fields properly. As I have understood classes with no
default constructor can not be arguments of generic types. Why I can not
specify "new ( smth. )" as a constraint of a generic parameter? Or may be
the document http://www.msdn.microsoft.com/vcsharp/language misses this
case?

Default constructors are only required if you specify the "new" constraint -
ou don't need them for generics in general.

We didn't add more complex constraints for constructors because we didn't
think the added utility was worth the additional complexity

I've been bad about documentation so far but I'm going to try to be better. I've mostly worked alone so I'm the only one, so far, who's suffered from my bad habits. But I'd like other programmers to have an easier time understanding what I do. Therefore this weekend I'm going to spend 3 days just writing comments. Before I do it, I thought I'd ask other programmers what information they find useful. Below is a typical class I've...

I promised I'd put together a PEP for a 'generic object' data type for Python 2.5 that allows one to replace __getitem__ style access with dotted-attribute style access (without declaring another class). Any comments would be appreciated! Thanks! Steve ----------------------------------------------------------------------

As a self-exercise, I am trying to write a generic Priority Queue, which would store any type and and accept any user-definable "priority" function. After much tinkering, I came up with something like below: class PMinimum { public: template <typename T> bool operator()(const T & a, const T & b)

Hi, Either I am missing something, or there is a compiler bug in the way inheritance from generic s is treated. In the following code, class c2 inherits from c1_generic. c1_generic has T as a generic paramter, and in the inheritance, class c2 specifies c3_T as the value of this parameter. class c1_generic defines 2 constructors, 1 of them taking 1 parameter.

I've written an abstract base type which uses generics to provide XML serialization and deserialization methods for use by its derived types, but I'm seemingly unable to write it in a way which completely satisfies FxCop code analysis.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
