Changing ToolStripStatusLabel Text To Connected If Connected To A Network
Apr 4, 2011On my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

View 5 Replies2 Clients Connected Via Server / Network Code Causes Slowdown Of Picturebox Movement
Aug 10, 2011I have 2 clients connected via a server program.When 1 client hits an arrow key, a picturebox moves on client1 and on client2.Before adding this network functionality, the picturebox on client1 moved fast with each click.Now, there is a delay of like 2-3 seconds.I know the code isn't optimal, but i'm not a networking wizard.What i'm doing is when pressing a key on client 1, it passes a text to a textbox in client 2 which then has the picturebox move in client 2 depending on the text.The slowdown occurs on client 1, which is odd because the picturebox isn't directly connected to the network code.[code]

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:

.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).

Oct 28, 2010i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

View 2 RepliesCan't Disconnect From CR-connected Database
May 30, 2006I'm viewing reports on a VB.net form using CrystalReportViewer. Once a report is opened, the Access database that is used within the report is locked (i.e., the Access MDB file can't be deleted). Even after the report is closed, the database stays locked until the VB.net app "ends". This is a problem because I want to be able to delete the MDB file at some point while running the app and can't. The VB.net app starts by opening a form named "Startup". No database connection occurs here. A button is pressed using this [code]I must not be properly closing the CrystalReportViewer or the Report form.How do I close the Crystal report and unlock/release the Access database?

View 7 RepliesClient Still Connected To The Server?
Aug 24, 2011My first post here in vb forums. I'm new to sockets programming since I migrated from Winsock and I learn a lot from Atheist. using his code, I can't access the messageReceived() every time a client sends a message on the server. but then I put a code to catch the message on sub doRead() and I can retrieve the message. My problem now is how can I determine if a client is still connected to the server or not so I can delete it on the ConnectedClient ?

Note: the server runs on Win7 x64 ultimate and the clients are laptops on win7 x86. I read a comment that the server should be having a static IP address, but when did it together with the clients, It still doesn't work. I am just using a switch for the network.
