c# - Handling being online and offline -

-

I have an application that calls an online database if I lose connection to the Internet or the database is closed My application will crash if it goes.

What is the way to handle this?

My own approach is an object, calling the database all the time and if an exception is thrown, then an event is removed which registers all other components and then some functions are disabled. Are there.

Is this the right way or better solution?

It is difficult to say that what would be best for you to know the bigger picture, but I have 3 ways Think that you can potentially put these situations in hand:

1) Timely handles connectivity issues well and just report them well
2) Like You say, from time to time voting connectivity and disabled functionality if "ping" fails.
3) Work with local copy of BB, then when you have connectivity, make updates synchronously to main DB at one time

IMO, I will go 1) or 3) Option 3 best user experience Option 1 potentially involves at least God's efforts.

With Option 2, you have a problem, no matter how many times you vote, you can influence the connectivity problem at any time.

Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
