Add The Ability To Receive SNMP Traps?
Jun 3, 2010
I have a need to add the ability to receive SNMP traps into one of my server apps (written in VB 2005). I have setup a UDP listener on port 162 (SNMP trap port) and can successfully get the trap message in a byte array no probs.
The problem is that I have no idea how to make a meaningfull message from this byte array. Does anyone have any pointers / code to either translate into a meaningfull message stream or a better way of adding this type of functionality (without adding 3rd party dll's etc).

I need to create a monitoring mechanism using SNMP (in .Net). I think we'll be using an nsoftware component to handle most of the work. It appears we must use 'traps' to communicate from the agent to the server. We'll have a number of different traps and various information detailing each trap. What is the best way to implement custom traps? That is, what is the best way to not only send a trap, but also send the information describing the trap to our 'snmp manager'? I think this is done through "variable bindings". To use "variable bindings" do we need to create our own "enterprise number" and use an "enterpriseSpecific" trap? Should we implement our own, custom MIBs or can we just send the data we need with the trap (via variable bindings)?

I have created an SNMP class. And then I want to test this class, so I create a program which imports this class ...
Imports SNMPClass
Module Module1
End Module
Public Class SimpleSNMP
Public Sub Main(ByVal argv As String())
[Code] .....
I got an error in this line
Dim conn As New SNMP()
Which says "SNMPClass.SNMP is not accessible in this context because it is friend"..
I am using Visual Studio 2008

I have been trying to get the Alert Code from my printer at work to see what exactly is happening however each time I send an SNMP query it doesn't return any results. I am using SimpleSNMP references. The printer is a Canon iR-ADV C5045.
This is how I call the function:
Dim strAlertCode As String = SNMPQueryGet("1.3.6.1.2.1.43.18.1.1.7")
This is the function:
Private Function SNMPQueryGet(ByVal OID As String)
Dim strResult As String = "True"
Dim host As String = "192.168.1.202"

I want to make a program that can play MP3-files from my FTP-server.I know how to play, pause and stop music from stream, but i don't know how to add seek-ability.You know, like in Spotify or Grooveshark, they play streamed audio with seek.so, i would like to be able to seek, and the trackbar would show where in the song you currently are.So, my questions are:
1.What codec should i use? I have NAudio, will that work?
2.Is there any examples or tutorials on how to do this, any at all? (i couldn't find any)

When it comes to Backgroundworker's, I just make a total mess, even after reading over and over again the Backgroundworker component info on the msdn site... I have a code I would like to run on the form but if I do it with a simple "Public Sub" it will make the form lag, freeze, until the operation is done. So I try to paste the same code into a backgroundworker, and use Runworkerasync, but I get errors stating that the backgroundworker can't access controls on the form.

I have a system on my webbrowser that allows the user to choose their Search Engine out of a selection I organized. the down point is that I have it set so when they click save it will just hide, because if it closes the settings will be reset and not saved. However I want them to save. Here are my codes to the search button:
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If SearchEngines.RadioButton1.Checked Then
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate("http:www.google.com/search?hl=en&q=" & SearchBar.Text & "&btnG=Google+Search&meta=")
[code]....
This is the code of save:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide()
End Sub
I would like it so it saves when the whole program is closed, so when they start up it's automatically set so they can search on their favourite search engine.

So I am trying to make a program where the user is limited in moving the mouse to a form. I still want the user to see whats going on behind the form but not be able to click on anything but my form.
I tried using this
Cursor.Clip = Me.RectangleToScreen(Me.ClientRectangle)
The problem is that if the user clicks in certain spots on the titlebar...the mouse is unlocked. The machines this is going on has a ball type of mouse so if you scroll fast and click fast enough...it can also unlock.

if there was a way to emulate the application.settings file's ability to do something like the following:
If I add an item to the settings file editor say Variable1 with a a value of "foo"
I can then go to my.settings.default. (and at this point) Variable1 is item that is an option after I type the '.'
Is there a way to do this for a collection? To where I have
Collection1. (and when I press '.' the name of an item would show up?)

I have a simple query that fills a datatable from an Access DB. There are about 1.7 million records returned, so I would expect it to take a little time. At first, the query was a very simple one, and it took a couple seconds to fill the datatable. However, I really wanted the ability to restrict the rows by a certain date field, which meant a single INNER JOIN to a different table. Having written this, I verified that it was correct by copying the SQL string into the query builder in Access. The query, in Access, took a couple seconds to complete. That was comparable to the time I was seeing before I added in the join.
However, in VB, the query isn't completing at all. After 60 seconds, I get a message about a ContextSwitchDeadlock stating that it hadn't been able to transition or pump messages in a long time. Frankly, since the exact code works fine when I remove the JOIN, this seems like it is either a deadlock internal to the Jet engine, or the error message is an artifact of a very long running query. My question is why a query (albeit a large one) is hanging in the VB program when the exact SQL runs in a couple seconds in the Access query designer, and when I remove the JOIN, the query runs in a couple seconds in VB?

I have taken an interest in creating a SMTP server in vb.net that has the ability to hide ip addresses in email headers.I see that some people claim that it's possible around on the internet, but I haven't seen any direct source code to create an anonymous smtp server in visual basic 2008.Now I know that it's legal to send emails via a masked ip address and I believe that it's also fair since some people believe in anonymity, but I am in all means against spammers.
