asked on

a few general pointers reqd

https://www.experts-exchange.com/jsp/qManageQuestion.jsp?ta=perl&qid=20001415

I have posted this in the PERL programming area too .BUT your answers needn't be PERL specific at all !

what I want to know specifically from the gurus here is

1) how do applications like "ICQ net detect" or AOL detect whether a user is connected to internet or not ?
do they wait for any Windows specific system calls , signals  ?
can you give an example for trapping such an signal using a language of your choice ...


2) What is the general procedure/code/steps to follow ,
to make an application run in the background and show as an icon at the system tray when a
user presses a key
again can you give an example l using a language of your choice ...

3)What is the general procedure/code/steps to follow for activating the
Dial up connection if the user is NOT connected to the internet ?
same as above ..some examples please


4) IS there any free installers available ?
 I want users to just download a .exe file and the application must install by itself  asking questions such as
do you want this to start at system startup? ,
which directory do you want to install ? etc


chris
thanks

This question is still open today, perhaps it was overlooked or just lost in the volumes.  Please return to this question to update it with comments if more information is needed to get your solution.  If you've been helped by the participating expert(s), you may just convert their comment to the accepted answer and then grade and close.  If an answer has ever been proposed you may not have this option to accept the comment as answer, if that is the case, ask the specific expert you wish to award to post an answer.     You'll find that you get what you need more quickly if you remain active in your questions and provide feedback.  Finalizing questions benefits you and others who then search our PAQ for just this solution, and rewards the experts who have provided you the information.  A win/win scenario.  Please do not accept this comment as an answer,  it is merely a reminder.  
If no response has been received by month-end, I will delete or accept an answer based on the information given.  Experts, please feel free to offer input.  I will have another moderator (who is also an expert) look at the question as well to ensure we do the right thing for this question (PAQ or delete).
Some additional options and information:
If you wish to award multiple participants, you can do so by creating a zero point question in the Community Support topic area, include the link to this question and tell them which experts you'd like to award what amounts.  If you'd like to delete this question, use the same process as above, but explain why you think it should be deleted.  Here is the Community Support link:   https://www.experts-exchange.com/jsp/qList.jsp?ta=commspt

P.S.  For any year 2000 questions, special attention is needed to ensure the first correct response is awarded, since they are not in the comment date order, but rather in Member ID order.
