Industrial App: Raise An Event For Something That Doesn't Have An Event?

Sep 15, 2010

I want to raise an event for an opto-input state change but not sure if I can. Basically I have 4 opto-inputs on a PCI control card - one of which changes pretty rapidly - that I currently poll with a timer. I'm looking at getting a proper hardware counter for that but the other 3 are production status indicators. I'd prefer it if they alerted the app to a state change though.

Depending on the state of one of the inputs I have to fire a relay which simulates a button push. Having been playing with serial ports and getting a very useful app built for logging production data into a SQL Server DB I want to re-visit a proof-of-concept system I built a few months ago.

Current code - which works fine - but I'd like to change is like this:

Private Sub tmrOptoInput_0_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrOptoInput_0.Tick
'Read OptoInput_1 to Monitor Track State...
Dim aType As Byte ' replace Byte with any other type

[code].....

Having 4 inputs so I need 4 timers, plus another one that polls the database and checks a status flag which triggers the app to start logging. I'd like it to be event driven rather than timer driven if at all possible but I don't know how and there's nothing in the control card docs. Also I can't seem to find anything relevant on the web.

Cell KeyDown Event - The Event Does Not Exist?

May 24, 2010

I have this code in the onKeyDown event of the datagridview.

Private Sub DataGridView1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown
Select Case e.KeyCode[code]....

This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.

Raise Event After All Others Done?

Apr 8, 2010

Is it possible to run a sub routine on my form after all other sub routines have finished? I am having a problem using a filewatcher that watches a certain path and runs an SQL job if a certain file is pasted. For some reason my procedure leaves a file behind sometimes and others it does not. I was wondering can I use a form event to run a different procedure after all other sub routines on the form are completed that would check this directory for remaining files again?

Raise Event From A Sql Database?

Nov 29, 2010

I have an MDI parent form and 2 child forms. Each child form has data bound controls bound to the same sql table; one from is for displaying data and the other is for editing data. After the editing form closes, I need to update the data in the display form (if it is displayed). I can think of a few ways to do this, but I would like the display form to simply respond to an event raised by the database. Is it possible to create (and raise) an event in the database proper? If not what is the best/acceptable way to update data on a data bound form?

How To Raise Event In Mocked Interface

Jan 31, 2012

I'm trying to raise an event in a mocked interface. I can get this in C#, but for some pain-in-the-butt reason can't get it working in VB.Net. Hopefully I haven't missed the boat conceptually and all I'm missing is some syntax. This is similar to the code I'm working with:

Public Interface ISendable
Event SendMessage(message As String)
End Interface
''**********
Public Interface IPrintable
Sub PrintAnnouncement(announcement As String)
[Code] .....

How to complete or correct the line in my test class that begins "sendable.Raise..."? Maybe there is more setup I need to do, but the Moq site didn't seem to indicate this is the case.

Raise An Event From A Custom Class?

Nov 14, 2011

I have a Windows Service project designed to monitor an email account and make entries into a SQL Server database when certain emails arrive. This is a rewrite of a similar winforms program that works just fine, except that it requires that the computer be logged into an account and the program started manually, which I can avoid by using it as a service.In the service I maintain a list of logged messages - basically just a string and a timestamp indicating that something has happened. (That list is shared out over a WCF service but I think that's immaterial, at least at the moment.) In my custom class I declare a public event, and elsewhere I raise that event. For some reason, though, the RaiseEvent isn't being run in the service. For example:

[code]...

The problem in this case is that _pc_HandleEvent isn't ever being called. If I duplicate this setup in a regular winform program, everything works like it should. What am I doing wrong? How do I get a service to handle events raised from other classes?
