A class to ping to many hosts the same time by .net 2.0 async Ping calls in the background. Its implemented as a FirstIn-FirstOut queue which accepts every item you put in only once. Its used to hold IP adresses or hostnames (will be resolved by DNS requests). The destination hosts will be async pinged and an event will be raised for every result. Its carefully written and documented with VS 2005-VB.Net and tested within a network with about 1000 clients. _______ UPDATE 1: Thx to Tom Waller: Memory bug of .net's Ping object fixed. See details in code. _______ Comments and suggestions are welcome, votes are motivating - thx for! 4/2005, 12/2006 - Light Templer

Hello Lite :-) I havent looked at your code yet. No time on my way to work. Just wanted to say I am glad to see you in PSC .Net Area. Looking forward to see great submissions from you :-) (If this comment was disrespectful, please report it.)
Thx Knoton :-) I'm glad to see guys like you and Mario Flores G. in this PSC area, too! With VS 2005 and .net 2.0 the time is right to go further. The advantages are too much to stay on VB6 only ;-) Kind regards - LiTe (If this comment was disrespectful, please report it.)
The .net section of PSC is a much more difficult corner than the VB corner: Less submissions und nearly none votes even for quality stuff. Folks: What are you expecting if you don't give comments / votes to authors which spent many hours to write demos and docs to a class? They don't need this for themself, its just for you! ;-) So if you don't recognize this PSC section stays as poor as it is right now. (And it should be the future of programming!) Just my thoughts - regards LiTe (If this comment was disrespectful, please report it.)
Hello Lite, I have just tried it out. Works great :-) I especially gonna get good use of your enums for comp in network and AD. Thanks :-) (If this comment was disrespectful, please report it.)
Hmmm Good work! 5 From me :) I dont mind voting for good Stuff! ;) The code can be much improved via proper exception handling ,,, (If this comment was disrespectful, please report it.)
Syed, thx alot for the first hint to improvement! Plz tell me more: What 's to improve in execption handling? Class works fine for me so far, but if there is something to get better: Anytime! (If this comment was disrespectful, please report it.)
Syed: Thx for your details in your email to me. ____ All: All needed exception handling in ParaPing class itself is included of course. Syed just means the small demo app :-) (If this comment was disrespectful, please report it.)
Nice one Lite.. but consider coming over to C#.. ;o) Think about adding some AD dimensions to this, (in est, object management), good examples of that are hard to find. As for legacy vb side, I disagree, only thing people typically vote for [newbs], are user controls, (a fact that is much exploited by the shameless.. ;o) 5 from me! (If this comment was disrespectful, please report it.)
Comments are tooo HOT !! :)) LiTe... I just started learning .Net and I know ur posts are always helpfull for anyone to improve their knowledge. NICE WORK & CONGRATS on ur CTOM @ vb.net (If this comment was disrespectful, please report it.)
Absolutly wonderfull coding here. Truely async pinging all the way. Exactly what I was looking for! Also, thanks for all the help you gave me with the memory issue.
Kindest regards.
Tom (If this comment was disrespectful, please report it.)
Light Templer, good work. I've followed your stuff right through from VB6. Good to see you here in dotnet. (If this comment was disrespectful, please report it.)
Great work Light! Just getting into .net and this is a very good example. Big fan of your VB6 work. Please keep it up. (If this comment was disrespectful, please report it.)
What is the "Speed in MS" value used for? I noticed the max simultaneous pings are for the maximum at one time. but what is the Speed in MS value supposed to do?
This is very good code, exactly what i was looking for, but just curious as what that does as I cannot see any difference when I change it. (If this comment was disrespectful, please report it.)
You can follow this value from demo form code to class' property 'Interval': It gives the timer ticks in milliseconds to wait before next Ping has to be send. The default is 50ms - a very short time. Double it: It's is still a short time :-) It 's to prevent an "over flood" of your network. If there are intruder detection systems installed, maybe they ring the alarm bell, if too many pings are send with too high frequency. (If this comment was disrespectful, please report it.)
