Sounds interesting. Good luck to you.

Cool. I'll take a look.

The idea looks like a winner article. You can create a class like System.IO.Directory, to have easy access to some branches and leaves, just as collections you can scan with a foreach() statement.
Best regards,
Jaime.

Hi Jaime,
Thank you for your comments. Despite the fact that this idea came to me just recently, the progress made on it in just one month was astonishing.
First off, see website www.prosyslib.com that I did for the project. Second, see my first article on it http://www.codeproject.com/KB/COM/prosyslib2.aspx. And do not mind lowered rating on it. I suspect that it was hugely because for the first couple days the article was published it relied on source code availability from the website. Apparently, many didn't take this kindly, so they gave a low vote. But as i fixed it, included the source into my SDK installation, i hope to be getting better votes from now on...
Regards,
Vitaly

Well, 32 votes for your article in the first week is really good.
A screenshot of your sample application at the begining of your article will help you to gain attention from readers.
Best regards,
Jaime.

thank you for your vote! I really appreciate it. Doesn't look pretty being underdog with a good idea 
There's plenty of work in-progress. And i'm preparing a new article now that will be called "ProSysLib: Dissecting the Process". And it will be about extension of namespace PSLSystem->Process that with v0.5 will include a lot of stuff to know about the process:
Powerful collection of threads and windows, version info, process details, etc...too many to list them here.
have a good day!
Cheer'o!

Also, about the COM stuff I have to say this:
.net programmers don't like COM because .net superseeds that with assemblies, that don't require registration.
C++ programers don't like COM too much, because it will need wrapper classes and code overhead due to type conversion.
I suggest to do this: Start a new project, put all your logic into private and public classes, methods and properties. Publish this library for .net developers.
Wrap this library to expose as a COM object, and publish it too. I guess you will have more .net users than COM.
Best regards,
Jaime.

Jaime,
One of the hard challenges of this project is to get this idea into the heads of developers, to make them understand that this is not just a COM project, it's a little more than that. For example, both of your notes are not valid:
1. You do not need to register this library in order to use it. I invented and implemented Stealth Deployment technique that i briefly mentioned in the article and described well in ProSysLib SDK.
2. C++ programmers won't need a single wrapper to use this library at full strength, because the namespaces get mapped onto the smart pointers automatically. See one C++ example that i showed there in the messages.
Like i said, the challenge is to convey this idea of simplicity beyond your regular COM stuff.

Besides the fact that your arguments can be valid, you cannot change this premise: .net developers don't like COM objects, no matters which technologies or tricks you are using, wrapping is necessary for .net project, that's why I initially suggested to expose your library like the System.IO.Directory class or maybe to Registry class (both are tree collections).
Countersense, phrases like "full managed library" are attractive. So, you can wrap your C++ library into a .net assembly alternatively. Still you can use your COM wrapper for other kind of users (c++, vb6, delphi).
From a commercial perspective (no matters if you have profit or not), this reduces your market segment. Consider I am an experienced C++ and C# developers, so you are hearing an opinion from both sides.
Best regards,
Jaime.

".net developers don't like COM objects" - this is what i am trying to change. And from what i hear, i need to publish another article to explain all .NET developers that using COM from .NET can be just as elegant as .NET assemblies, no unmanaged code, no COM registration.
I will write an article here about it soon.

Hehe, you won't change it. COM is coming to be a deprecated technology. Trying to stick to it is like trying to keep VB6 alive, or that DCOM is a better choice than .net Remoting. You cannot convince a .net developer to replace the .net assembly architecture with COM architecture.

Better you put a new thread in the CP forum to discuss this. I think you will have a low rated article trying to defend your point of view. But, it is our choice.
Best regards,
Jaime.

Hi Jaime,
Believe it or not, but I have been hearing convincing speeches about short-coming death of COM since 1998. As of today, Vista is still by 99% sitting on what's built on top of the COM layer
I took my chances with publishing here, and the results you can see for yourself:
First Article: http://www.codeproject.com/KB/COM/prosyslib2.aspx
Second Article: http://www.codeproject.com/KB/COM/prosyslib3.aspx
Second article as of this moment is the Editor's Choice on CodeProject, sitting on the main page, i'm getting some very good feedback on this.
I would say that i will be the first one to dance when COM really dies, but then ops, i might be just too old for dancing when this happens
Regards,
Vitaly

The .net framework provides a queue(of T) which is fine for single-threaded programs, but is not thread-safe. There's a synchronized version, but since it uses locking it runs the risk of priority inversion and other such problems.
I've implemented a fairly simple queueing implementation in VB.net with the following properties:
-1- There are no locks or waits, except that the calling program may elect to wait for data if the queue is empty.
-2- There are a few spinlock loops, but there is no possibility of livelock since each loop will only spin if another thread successfully performed useful work while the loop was executing.
-3- Conceptually, the base queue object does not hold data, but is a place to attach reader objects. Data which is written to a queue will be queued in all reader objects.
As an example situation where this class could be used, think of a multi-line chat BBS. There's a central message queue for all broadcast messages; when a new user logs in, a queue reader is created for that user, attached to the central queue. Whenever a message needs to be broadcast (either a user typed something, or the system wants to report something) it is placed in the queue, where it can be read by all attached readers. Data can be added and removed by any number of different threads without need for synchronization.
I've never written an article for CP before (and haven't done a whole lot with VB), but I think the class seems like it should be useful; I would appreciate feedback and advice (e.g. should I allow the user to receive a WaitHandle from a queue reader, so as to allow the use of WaitAny? If so, can I prevent the user from doing anything with it other than wait?) Would anyone be interested if I were to write up such a thing?

If you think the class is useful, chances are someone else will too. If nothing else, writing the article will be good experience.

Any Sharepoint experts out there who can give some examples of using this WebControl? Googling this topic (and SPMenuField) seems to almost exclusively point back to this[^] - which is fine - except that I'd like a deeper understanding of what is happening 'under the hood'. MSDN docs are virtually non-existent...
An article would be lovely!

It is hard to read some useful here because there are lots of off-topic posts.
Could you delete all them to make this forum more readable?
Best regards,

Including this one.

Seriously, while I agree that there are a lot of off-topic posts I think a better way to manage them is needed instead of deleting them.

Of course you have to delete this too 
A move-to-other-forum option would be a better feature, I have seen this feature in some other forums like Experts-Exchange. Moderators use to move the question because some members don't post to the proper area.
Best regards,

Yep, and now your post and my response.

I actually suggested [^] that, along with a few other features, right after my original response.
