Internet Connection Tester

pilky1986 · March 9, 2014

Hello,

I was looking around the net for a simple protable program to test whether you have an internet connection.. in short i couldnt find what i wanted so i wrote one.

After looking on the forum i found some code snippets from others who had started to this kind of thing, but no completed project.

Post: '?do=embed' frameborder='0' data-embedContent>>

Autoitsnippet: http://www.autoitscript.com/wiki/AutoIt_Snippets#IsInternetConnected

Function (by Guiness): '?do=embed' frameborder='0' data-embedContent>>

I have attached the full code and compilied executable.

All constructive comments / improvement ideas / actual coded example imporovements, welcome.

Version 2

Version 1

Update:

09/03/2014 - v1.3 - Added a sleep() to the program loop to prevent high constant cpu usage - credit: wakillon

09/03/2014 - v1.2 - Added in another test (Microsoft Windows Test #2) using a function written by auto it forum member Guiness

09/03/2014 - v1.1 - Removed unnecessary includes, moved global variables to the top of the code - Credit: wakillon / water

Where ?

pilky1986 · March 9, 2014

Whoops, might help if i clicked upload :-)! thanks

water · March 9, 2014

A good script to check is >microsoftinternetconnectivity tester by Guinness.

Whoops, might help if i clicked upload :-)! thanks

Ok, tested and approved

Remarks :

Only GUIConstantsEx.au3 is needed

It's more secure to declare your global variables at the start of the script.

What's the utility of : #include "FormsInternet_Connection_Tester.isf" ? :huh:

water · March 9, 2014

ISF files are used by ISI360's >ISN AutoIt studio.

i know, but why add it to the Includes list ?

water · March 9, 2014

I think he just forgot to remove it.

wakillon · March 9, 2014

I think he just forgot to remove it.

Yes or may be he used "include" instead of "fileinstall" to include it to the executable...

pilky1986 · March 9, 2014

Hello,

Thank you for the feedback.

You are quite right, i should of included the global variables before anything else, i have amended this. I forgot to remove the other #includes, they were in there because i was using them but in the end did not need them. I forgot to tidy that up!!

I will have a look at microsoftinternetconnectivity tester to see if i can integrate this into the program also as another test.

Finally with regards to "#include "FormsInternet_Connection_Tester.isf" as water says its part of ISN Autoit Studio, if you remove the include then your script wont compile as the related form/gui coding is not then included. I had a look over ISN Autoit Studio's example project and it appears to be the way the person has designed it to be included in peoples scripts, or at least that is what i have concluded. However, i may be wrong?

If there is a better way of doing this (? Fileinstall) then i shall happily go back and resolve and re-upload. Thanks

Just noticed that when the program is running (idle, i.e. not testing) it runs at a constant CPU usage of 25%.. struggling to figure out why , any thoughts?

Add a sleep to your loop

Func _startgui()
    GUISetOnEvent($gui_event_close, "_ExitGUI", $internet_connection_tester)
    GUISetState(@SW_SHOW, $internet_connection_tester)
    While 1
        Switch GUIGetMsg()
            Case $gui_event_close
                ExitLoop
        EndSwitch
        Sleep ( 30 )
    WEnd
EndFunc

How obvious! Thanks :-)

Its been a while since i used autoit, getting back into the swing of things now.

I like that TechCoder, its a simplified way of doing what Guiness has done (which is the "Microsoft Windows Test #2", in my script). Nice code! :thumbsup:

Does any one use a VPN here?

I do, and "Microsoft Windows Test #1" always fails when on the VPN (works if not) and the other test are successful, i assume its a limitation of the windows dll function call....

If someone could kindly verify if "Microsoft Windows Test #1" also fails on a VPN that would be greatly appreciated! :thumbsup:

TechCoder · March 9, 2014

May be 'simplified', however, as stated in that post, my 'vote' is for the way guiness presented it - reads the dll the same as MS products - i.e., doesn't consume more resources and is 'equivalent' for many purposes.

When I get some time I'm going to study your multi-methods a bit more for one project I have (my program is faster than MS and works great for special purposes) and see if there is some 'combo' that makes for a better fit, though, lacking additional tests, I would say that a choice between the dll method and the 'fast' one that mirrors what Windows does (only with your own timer) seems to be the best.

Oh, on the VPN - sorry, can't help you, but I understand/feel that pain - being behind a router that is still running, but no internet connection is what caused me to research and get that function going.

BTW, I posted on this as I like your GUI idea (though would like to see it _smaller- like 150 px high or something - would make a neat horizontal or vertical 'light' bar maybe?)

I think most projects are driven out of necessity / curiosity. Like yourself, i have written this for a specific purpose, as i have a need to demonstrate to end users whether they have an internet connection. I built it in this way so that a user could run the app and test to see if they have an internet connection. As you said, they may have a LAN connection but not a WAN.

I like your thought about a smaller version, although personally i wouldn't have a need for it, so to be honest i doubt i would code a GUI for it

However, i think i could take this further by using a scoring method, based on each test to take away any interpretation required by the user. I think to be safe you would want to use a three-pronged approach to analysis which would require more tests than what is currently built in, probably pinging more DNS servers and potentially using more in-built windows functions, perhaps even checking TCP connections.

Depending on the outcome of further VPN testing, i will probably add in a message pop-up to notify the user that if test #1 fails and if they are on a VPN that this test is expected to fail (assuming the testing concludes this)

What was your project TechCoder?

TechCoder · March 10, 2014

project is a commercially available product (sorry, can't/won't discuss that publicly, though the snippet is now 'open source'... - funny enough, 'clearly' explained at )'>)
