Set A Timer Going Which Is Set Off By An Output From An External Signal From A Machine Tool?
Nov 17, 2009
What I am trying to do is set a timer going which is set off by an output from an external signal from a machine tool. At present the code is activated through a button on my form. This is the code I am using Public Class Form1 Private CompTime As System.Int32
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CompTime = Environment.TickCount End Sub Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Label2.Text = TimeOfDay End Sub

I need a walkthrough to :
1. Get a list of available usb ports
2. Send an output signal through the usb (if possible with variable intervals)
3. Close the usb port (so that no signal (current) comes out )

how to redirect outputs from console to a window form text box,but the console application I'm using is always running real time, thus my .net application hangs until I close the program that is read real time.The code displays the application to a 2nd form with a textbox multi line. Until I close that my entire program hangs and the console application monitored runs.
How do I code it to:
1. Run real time without hanging the entire program.
2. the console app must run at all times. (figured how to hide/ and no window created for it)
Sub Console()
Form2.Show()
Dim myCon As New Process
myCon.StartInfo.UseShellExecute = False

I've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads

Is it possible to send information to a BackgroundWorker thread while it is running? Here is my scenario: Parent thread calls background thread to send a data request to a database. If it's a big complicated query it can take a while for the db to respond, so putting the db request on the background worker thread is great. My app can do other stuff while the one thread waits for the db.
Now, db responds with beginning of data. I want my background thread to report back meta data about the result set to the parent thread. No problem there, I can use a custom user state object and the ReportProgress method. But now, how to I send a signal from the parent thread back to the worker thread? I want the background thread to wait while the parent thread does something, and then tells the worker thread to keep going or quit. I know how to cancel a background thread, but I want the parent to be able tell the child some information other than "cancel". Here's one way to think about it:

o I've had to reinstall both the .net and visual studios 2010 to get back to being able to program my game, yet this strange issue is still in existence...all of a sudden, like 4 hours prior to not being able to program anymore, I ran into the issue of my login form FRMlogin.vb not running upon clicking the button that sends you to its page... it will not show up for some unknown reason, and both me and my programming buddy cannot figure out what is going wrong here. I restarted my computer twice now since reinstalling visual studios 2010 express, and the same issue is here...here is the code for the forms
the play_b4.vb code
Public Class play_b4
Private Sub registered_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CMDregistered.Click
FRMlogin.Show()

I have looked absolutely everywhere for documentation on wifi adapter usage programmatically in any
language, and have found tons of code for Windows Vista and prior. There has not been a single DLL
or code snippet that functioned on my laptop. I suspect it is because I am running Windows7, but
just in case here are my laptop specifications:[code...]
This obviously has some flaws in it, particularly it adds all the values to the same double.
