VS 2008 Network App - Send Message Or Network Package To Some Of The Clients In The Network
Aug 18, 2009Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

VS 2008 My.Computer.Network.Ping() Cannot See Network Under Windows 7
Nov 18, 2011I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

.net - Using A FileStream On A Network When The Network Drops?
Mar 26, 2012I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).

C# - Using SQL Server DB Over A Network?
Feb 16, 2012I want to use my SQL Server DB over a network. I have setup server client applications.The thing is for my current DB, I need to give it to server administrator who attaches the DB to SQLExpress instance and only then my network computers can access that.My question is, is there any way that my vb.net application could attach this DB through code at runtime, and DB gets all rights that are necessary to access it over the network?
I can attach DB using Create procedure but for this I need to know the sa password. Is there any way that I could achieve the same goal without sa passord and sa intervention?My only purpose is to enable my DB to be accessible over the network with all read /Write rights.

Aug 30, 2011I'm using the details on connecting to a server from a client here: [URL]
It's quite out dated but I just need it for a quick project. I need the client to auto-connect. This program will be running on the LAN only, is there a way to find on what computer the server is running on (i.e. all computers hosting the specific server on port x). I've seen it on a couple of games that run on LAN. Without access to the internet, they manage to display all available games on the local LAN. I'm doing this with VB.net.

How can I get the program to find every computer on the network?
