I have very well knowledge about vb.net but I am suffering from 32 bit code and 64 bit code problem.

The code is:

If NetworkInterface.GetIsNetworkAvailable Then

Internet Connection Best Practice?

Dec 8, 2010

What is the best practice way of detecting internet connection?

From Windows Vista onwards, a status is set in windows that is displayed in the task bar. However, I cannot call this function/api/whatever, since some of the client pc's are still on xp, and only due for upgrade in 18 months.

so do i use and request something like [url]... to try and see it it works, and on the catch block set the return value to false, or is there another way?

Second part of this question, If no network connection is available, I can use [url]... to dial a connection. Will this use internet explorer's settings, or dial the connection marked as default in DUN?

C# - Check Internet Connection In Silverlight?

Jul 1, 2010

I'm writing a Silverlight 4 application and would like to check when opening the installed out of browser application, whether there is a valid internet connection (to then download some data from my website). I realise that I could put a try catch around a WebRequest but that seems a bit hacky to me.

Can't Seem To Establish A Connection Between My Two P2P Applications Over The Internet

Sep 14, 2010

I just can't seem to establish a connection between my two P2P applications over the internet(LAN works perfectly fine).

I have tried the following.
- Disabling Firewall
- Changing Port

The only way I can establish a connection is if I'm connecting to the same computer using the universal IP or the local. Does anyone have a fix for this? Oh and here is the error that I receive when trying to connect over the internet:

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 255.255.255.255:8787

Check Internet / Network Connection ?

Nov 19, 2011

This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.

If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.

If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...

Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.

I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.

All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.
