View 1 RepliesVS 2010 Making A Loop To Check A Status Before Going On?
Dec 1, 2009My next step is to allow a pause checking the status of the motor and or inputs before going to the next step. Reason is so it does not do many calls to the motor controller so fast. I need some help building a loop that checks status of the motor and if Motor1Active is 1 which means it is running that it needs to wait a bit and then rechecks itself. If it is not running it will continue to the next step command. Here is a sample of what I got but need to figure out say a 50ms wait before rechecking. I guess a loop that rechecks and waits 50ms and then rechecks the status and if done and reads 0 then it goes to the next step. if still 1 output data it waits 50ms and then rechecks. The following is what I got started with but need help with if then else and anything else statement.
' get the current status of both motors and the digital inputs
Private Sub GetMotorStatus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetMotorStatus.Click
Dim Motor1Active, Motor2Active, Motor1StepsLeft, Motor2StepsLeft, DigitalInputs As Integer

How To Detect Computer Network Connection Status
Jun 8, 2011I 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.
MySQL Connector - How To Keep Connection Open With Status
Apr 25, 2010I 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:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
'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.
VS 2008 System.Net.Socket Connection Status?
Dec 8, 2009im 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?

The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it.
