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 need to search for a specific process in task manager and attach (dock) my application to the window for that process. I have this working just fine. The problem I'm having is that sometimes this process may be running more than once (for example: running two Internet Explorers would put two iexplore.exe entries in Task Manager).
Is there a way to get the one that was opened first? I'm not sure how they get "sorted" in the Process list, but currently I am retrieving the first occurrence of the process and docking to it, but I'm finding that it isn't always the correct one. How can I make it always dock to the process entry that was opened first?

Basically, I'm trying to get a program to behave in the following way:First instance of the program opens up on PC1, opens a file for Read/Write access and then acts as the master program, doing a bunch of work on some other files I don't want a whole bunch of users accessing at once.Second instance of the program starts up, tries to open the file for Read/Write access, fails, enters Slave mode, opens the file for Read access, and periodically reads the status of the other files from this file.
That's the plan, anyway. If anyone can suggest a better way to handle the master/slave decision-making.Anyway, as a lead-up to implementation, I've got two instances of Visual Studio open. One is running a project called "GetFile", the other is running a project called "TryGetFile"."GetFile" has a Private myStream As IO.FileStream object and opens the test file using this line:
myStream = IO.File.Open("\[network path] est.txt", IO.FileMode.OpenOrCreate,
IO.FileAccess.ReadWrite, IO.FileShare.ReadWrite)
This works fine and, as far as I can tell, should leave this file accessible for further Read/Write access by any other process, which is fine for this stage of the testing."TryGetFile" also has a Private myStream As IO.FileStream object, but it attempts the following open code:
myStream = IO.File.Open("\[network path] est.txt", IO.FileMode.Open,
IO.FileAccess.Read, IO.FileShare.Read)
This doesn't work at all. I get an IOException, which reports that test.txt is opened by another process and I'm not allowed to play with it.Basically, I don't see what the problem is; I don't think "TryGetFile" is asking for any file access which "GetFile" forbids it from having. As far as I can see, "GetFile" shouldn't be forbidding any kind of access at all...

View 2 RepliesI have a sub-procedure which I want to run a different process, depending on what is currently running. I thought the easiest way to do this was by using an ArrayList of each of the campaign details & adding an 'Inuse' field to check to see if the Inuse field is set to 0 or 1. The problem that I have is that when running the process it is all happening at once & the integer hasn't been changed before the next thread kicks in so my threads are running the same campaigns. I tried to avoid the problem by adding a Thread.Sleep(100) delay inbetween starting threads but this led to exactly the same problem.
Here's an example of what I am trying to do:
Imports System.Threading
Public Class Form1
Private Campaigns As New ArrayList
Private ProcessRunning As Boolean = False

If so, what are they?

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..
View 4 RepliesI 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

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:

Container = ContainerGenerate.GenerateContainer()

View 1 Repliesjust 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.

View 2 RepliesI 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.
