Hello all,
One area where the .Net framework 1.1 is really poor is Collections : We've
got very few choice concerning the containers and their characteristics (for
example, ArrayList, Queue and Stack are the only "non-dictionary" avalaible
containers, and only Stack has some complexity specifications).
The worst thing however is the IEnumerator interface, which doesn't allow
for insertion, deletion or even *modification* of an item...

Thread Safety
Public static (Shared in Visual Basic) members of this type are safe for

Hi,
I am converting an existing native C++ program making heavy use of STL
to C#2.0 with STL usage replaced by the new generic collections. The
conversion has gone well to the point where I am replacing an STL map
instance by a System.Collections.Generic.SortedDictionary instance. In
need the collection to be ordered, and to have o(log(n)) look up - that
is fine so far SortedDictionary.TryGetValue does the job. I also need

I am starting to translate some code from ASP to ASP.NET (VB). I was able
to query ADS to get a users groups that they belong to, and also query a
group and get a list of users. However, I can't seem to get this to work in
VB.Net. Here's what I have:
OLD ASP Code:

I've noticed that in VS.NET 2.0 Beta 1 that none of the methods in
System.Collections.Generic.List are overridable. In my app I currently have
over 50 strongly typed ArrayLists that inherit from
System.Collections.ArrayList. Each of these types raise strongly typed
events for when items are added and removed (e.g., AddingItem, AddedItem,
CollectionChanged, etc.). One of my hopes for v2.0 was to create a single
generic List that replaces...

Hi,
Does System.Collections.Generic.Queue not have a Synchronized
method because it is already in effect synchronized, or is the
Synchronized functionality missing from
System.Collections.Generic.Queue? Putting it another way can I
safely replace a
System.Collections.Queue.Synchronized(myUnSynchronizedQueue) with a
System.Collections.Generic.Queue while porting a working 2003 project?
Thanks,

Hi,
I'm in the process of updating an ASP.NET v1.1 web app to v2. The app uses
ActiveDirectory a great deal, and I'm trying to use the new
System.Collections.Generic namespace where possible, having been advised by
several luminaries that that is a "good thing to do"... :-)
However, I'm experiencing a problem with the IEnumerable interface. (N.B. I
understand fully that I should be using the LDAP provider instead of the
WinNT provider...

Hello
I'm a network technician in training and I need your help.
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.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
