View 4 RepliesI have an automated program that batch prints PDF files to certain network printers. On occasion our print server will go down & screw up the automated printing process & lose prints. I am looking for a way to check the status of the print server before sending prints. If the status is not "OK" then I want to pause the automated process until the server is back to "normal". Can anyone tell me how I would check this status or where I should be looking?

I've came across a little problem with my tcp / ip server. My client can connect to it with 127.0.0.1 ( localhost ), and 192.168.0.X, but every remote connection fails to connect.
Here's the connection rituals:
Server
listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port)
listener.Start()
listenThread = New System.Threading.Thread(AddressOf doListen)
listenThread.IsBackground = True
listenThread.Start()
Client
client = New System.Net.Sockets.TcpClient(IP, Port)
client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf DoRead, Nothing)
I am trying to find out if the connection of my sockets (TCPClient) is connected or not connected. I am using the following code:

View 3 RepliesI'm trying to develop a windows application where i can get connected to remote server and look for process state going in remote server.We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.)
So our aim is to develop a windows application where i can get connected to that servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)
The UI at left side should will have list of servers i can connect to. When i get connected to server, at right side of UI, i want to display the status of installation (In progress, failed , completed).

I have an application for HR and I am trying to give feedback to users on login window wheather it is connected network and database.
For almost a week I am reading and trying to find a solution for checking connection state using a TCP Client (using socket class) In my scenario I have a TCP Client that is connected to a server (it is not controlled by me) and i want that from time to time to check the connection state, and reconnect if necessary.I have read a lot of information on the internet but i did not find a suitable solution.Briefly, these are the methods that i have found on the internet and try to implement.But unfortunatelly, i have found some scenarios where the TCP Server is closed and the TCP Client is still saying Connected 1.Example from MSDN

View 6 Repliesi m using wmi to get connected with remote pc with admin privilege code works fine on around half of machines in my domain but in case of other machines just throw rpc server not available error i google to solve this problem but all in vain
i tried with

2. allow dcom 135 port for exception
3. checked wmi services are running
but i m in dark side and i really give up to this problem of "RPC unavailble" i hv wasted few days in this,
The conditions are I don't have administrator privilege I want to see the status of a service in remote machine (server)I use the following code (vb.net with framework 2.0) to see the status
Dim sqlSvc As ServiceController
Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName)
If sqlSvc.Status.ToString.Equals("Running") Then
displayStatus("success", sqlSvc.Status.ToString)
Else
displayStatus("error", sqlSvc.Status.ToString)
End If
When running the code, InvalidOperationException is raised and found out that I need admin right in the server.Can I lookup the status of the service without having admin right in remote machine ?
I need to make sure that the connection to a POS printer is successful before writing data to the database and then printing a receipt. The POSprinter is normally of type BTP 2002NP but may differ. The common thing is that they are all connected via COM-port and NOT usb, so no drivers installed at all on the client. Can I send some kind of "ping" on a COM-port and check if a device is connected and turned on? Additional information, the application is developed in VB.net and Visual Studio 2008

I have a problem when trying to detect the computers network connection status.
Here is the code I have used:
Dim IsAvalible As String = My.Computer.Network.IsAvailable
If IsAvalible = True Then Label1.Text = "Connected" Else <code>
<code>If IsAvalible = False Then</code> I <code>
Label1.Text = "Disconnected"</code></code>
End If [/ICODE] End If[/ICODE]
But for some even when the network is disconnected or the computers wifi is turned on I still get the result of "Connected". I think there something wrong with the code.
I am developing an application with VB using the MySQL Connector Net [URL]. Now each time I go to load data in to a datagridview or in to text boxes on a form, I have to provide something along the lines of:

'Create connection to MySQL Database
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
conn.ConnectionString = MySQLGlobal
[Code] .....
I think it would be better to leave the connection open to the MySQL database while the application is in use. That way I can just continue to execute queries of inserting and updating, without having the delay of the application having to reconnect. Is there a way where I can create some sort of background task in the application that monitors every few seconds that the connection is still active, and if not it tries to reconnect until its reconnected? I am trying to have it so that then I can code it to just do queries, and when the connection breaks - it disables the form until it is reconnected.
im trying to detect if the connection is still active upon trying to send or receive anything. Now I have checks in place if it's connected then it will send or receive however... it's saying it's connected when it is not connected... and therefore my program tries to send and receive and errors.
I am determining if it is ok to send and receive by using the Socket.Poll(-1, SelectMode.SelectWrite)
if it's true then im connected and data can be passed..This seems to always be true until I send something and it fails..How can I catch the socket not being connected before it fails upon sending or receiving?
