Monitoring If A Variable Plateau's
Mar 22, 2009
I am dynamically adding values to list with each pass of a timer and after each pass I'd like to check if the last five elements in the list have similar values. After some time, the values should start to become constant. In other words, it would plateau.I tried to do this. Made sense to me (newbie) but I am getting errors like the bounds of the array are exceeded:[code]The list definitely works and is getting data from X. I thought I needed to ReDim the array but then I'm told ReDim statement requires an array. (ReDim platArray(Number-1)). By the way I'm using VB2008..

The below code (VB 2008) will check the print queue every milisecond for a job. It will then show the pagecount in a text box. It works great when im printing to a local printer, but As soon as I change my pc default printer to a network printer, I cant capture any data.

I want to create a bandwidth meter for Windows using vb.net, but I cannot seem to find anything in the .net framework for monitoring the amount of data in or out. I want to create this because I cannot find a good one for free, and I think it is something that people might want.If there is nothing in the .net framework for monitoring this, is there some P/Invoke calls I can make? If so, what are they?

I am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldnt work

We recently have one problem started where we have two processes monitor the same queue, but the diff b/w both is, one does the PEEK only and the other process it as soon as the message arrives (event driven). Do you think that pointing these 2 processes to the same que cause any problems OR are there something special sync things we need to do?

I have a SqlConnection global variable in my proyect that it is always open (I wouldn't like to start a discussion about keep the connection open all the time or close it everytime a transaccion is executed).
This variable is sent to every class I need to execute a function or method. Instead of checking the connection in every single operation, is there any way to monitor the connection state in a centralized way ?

I am writing a fairly simple web site monitoring app. It uses a timer to call a class that requests a web page and measures the response. Problem is that the third time the class is called the app hangs. looking at the locals box I see that the properties of the httpURL object are 'Property Evaluation Failed' .

I'd like to be able to log to the console every time an event is fired either in the object I've instantiated or in anything it's instantiated [ad infinitum]. I wouldn't see some of these events normally due to them being consumed further down the chain). Ideally I would be able to log all public and private events but if only public are possible, I can live with that.
I've Googled and all I can find is how to monitor a directory - So I'm not sure if this is not possible or simply has a name that I don't know.
The sort of information I'm after is similar to what's found in an exception - Target Site, Source, Stack Trace, etc...
Could I perhaps do this through reflection somehow?
To Give you an idea of the console App:
Sub Main()
Container = ContainerGenerate.GenerateContainer()
Dim TemplateID As New Guid("5959b961-b347-46bc-b1b6-cba311304f43")

just a newbie programmer here. With 1 week experience in VB2008. I'd like to ask for assistance on making one of these inventory systems concepts. I hear its one of the basic programs a newbie can make. This will be made for students financial monitoring. Like how much they should pay in an event. Of course will be needing to input student names and event names.
So I'd like to ask could you give me tips on what to do first?*Set aside the database stuff first.
Like the main window, or a sample of a form to which I could encode and update entry payments for students.Am not asking for codes here just samples of forms or softwares I could get some ideas.

I put together a small app I want to use on my local network for service monitoring across a few of my servers.
I'm using vb.net express 2010 with system.serviceprocess imported The problem I am having is that my code only seems to work locally, and will not retrieve the service data for any server on my network.
For example, my local machine is called "office-pc", and when running the app on it, I get all the service information.
Dim localServices As ServiceController() = ServiceController.GetServices("office-pc")
For Each localservice As ServiceController In localServices
ComboBox1.Items.Add(localservice.DisplayName)
Next
But, if I want the service info from my web server called "casper", I use the same code, but i change the GetServices() parameter like so;
Dim localServices As ServiceController() = ServiceController.GetServices("casper")
For Each localservice As ServiceController In localServices
ComboBox2.Items.Add(localservice.DisplayName)
Next
After a few seconds delay, nothing happens, ComboBox2 remains empty.
It was my understanding that GetServices() would get the local machines service info unless a machine name was specified, which in both cases is true.
So why isn't it working? Do I need to set something up on the network servers first?

how to catch faxing errors (outbound) using VB.NET.I am using this reference: MSDN Basically, the issue is that SBS2008 Event Log does not give the same amount of information that Windows XP did, so the users are being forced to look in the text activity log. Am I forced to loop through the log for new items, or can I actually catch errors as they come?My ultimate goal is to send an email report with the erroneous fax information (destination#, error reason, code, body or attachment).So essentially I need to figure out how to catch fax errors as they arise, by listening (this will be a VB.NET console app), and then I can take it from there.
Private Sub GetOutgoingArchiveMessages()
Dim objFaxServer As New FAXCOMEXLib.FaxServer
Dim vMessages As FAXCOMEXLib.FaxOutgoingMessageIterator
[code]....
This is what I am using to get the outgoing archive messages, but I either need to reliably get an error when it happens there, or get one on demand. I would much rather just poll the fax service for the information if I can.

I am trying to make an app that launches a window(Form Window) whenever a user click a folder in Windows. My app will be running in the background all the time and it will be monitoring the double click of a particular folder.
I have found this[URl]..But the problem is that, it checks attributes of the folder instead of the double click.
Is there anyway i can check the double click of a folder in Windows?

I'm trying to develop a simple app with vb.net in VS 2010 that could monitor the ODBC connections via DSN made on the macnhine running this app.My scenario is an application (non Vb) running on a workstation that connects to an MS Access database on a network share.
The application (non Vb) connects using a link (ODBC connection via Oracle 10G) to the tables on the Oracle side.My VB.net Application should monitor the machine running the main application for ODBC connections drops and alert me via email for example.My question is where in the framework can I find something to instantiate or reference in order to check ODBC connections states constantly as well as network disconnection issues as well so I can log and /or alert when possible for network problems and ODBC connection problems for all the applications that might run on the host (machine running my vb app).

I've searched in the forum thread for my needs, and I couldn't find any. So here is my problem. I need to monitor the data passing trough serial communication, between local serial port and some device with an application written in vb.netThe idea is to see the data without opening the port.For example I want to start the program, choose the serial port that I want to monitor, and then to start some other application that opens the serial port, and start to send data. Another device "answers", and I want to see the the sent and received data from the first program, and the process that opens the port.I thought that I can use the serial port event "DataReceived", but actually nothing happens. I think my approach is wrong. CHere is my code:
Imports System.IO
Public Class Form2
Private WithEvents sp As Ports.SerialPort
