Asp.net - Use VB To Query Remote Server Event Logs?
Aug 27, 2009
I am working on creating a web app that will query event logs on internal servers for events using a specific ID. Since most of the servers are running Windows Server 2003, I cannot use the preferred System.Diagnostics.Eventing.Reader method that I was hoping to use.
I've seen the mention of using WMI, but would like to avoid this if possible. I have dabbled with the System.Diagnostics class but cannot seem to get it working when running on a server. It is able, when testing locally, to query my event log, but displays nothing when put on the final server. There is no error that is displayed after the program is ran.
I am working on a project that includes having my VB app pull event log data from a Windows 200x server remotely. Does anyone have any code snippets or reference sites that would have information on remotely accessing admin functions/data in a Win2Kx server environment?
'set the date' Function FmtDigits(ByVal intValue, ByVal intDigits) FmtDigits = Right(String(intDigits - 1, "0") & CStr(intValue), intDigits) End Function

It fails around line 18. I have the script working without the remote piece so the failure is actually in the connections to the remote. If I change the authentication information I get an access denied so I know it making a connection.
I'm working on a program to read event log entries from several remote servers...its basically to automate some daily checks we doMy code works but is very slow as the event logs can have up to 60,000 entries in them.I only need to check the logs from the specified date but when i run this it appears to check from the oldest entry to the newest. does anyone know how to reverse the order it looks in? or to save the index it checked from yesterday to a file and only check newer entries next time it's run (obviously i know how to save a number to a file and read it back.. i just mean in terms of the eventlog API stuff!!!)
Dim elevent As New System.Diagnostics.EventLog("Application", currentserver) Dim elEventEntry As System.Diagnostics.EventLogEntry For Each elEventEntry In elevent.Entries
I am using VB 2008 Express. How can I read from the Windows System event log? I've seen many examples writing to an event log, but none about reading the log.
I would like to search event logs on my network for a certain EventID. I havent worked with Event Logs before and was wondering how difficult this task would be.
I have created a new VB2008 project and I want to display the newest 5 system errors from the eventlogs.So far I have this but all it retrieves at present is every entry where all I need is the latest 5. I wil eventually need to expand this to show EventID etc
I need to activate SSL when my application logs on to a ftp server. I'm searching the net and I can't find some piece of code to work, the username and the password are in plaintext, they are visible
I use this for now but it doesn't work:
Dim request As FtpWebRequest = CType(WebRequest.Create(ftp://ftpwt.com), FtpWebRequest) request.Credentials = New NetworkCredential("user", "password") request.EnableSsl = True request.Method = WebRequestMethods.Ftp.ListDirectory request.KeepAlive = False
i have managed to make an application to get print logs from the print server 2003, But now we have changed it to 2008.get print logs from windows 2008 server.i have activated the print loges from service manager -> diagnostics -> application and service logs-> microsoft ->windows ->print service and enabled the logs.using
Dim EvntLog1() As EventLog = EventLog.GetEventLogs(My.Computer.Name) For dhi As

I have a vb.net app that crashes after runnung for 6 hours. There is no error message. Application just stops running. No error noted in log. No flags in event logs. Is there a feature in vb.net that may cause this. Application uses excel 2003
I used to run the following code on WIN XP PRO and it used to work. But why not running anymore on WIN 7:
Dim Log As New System.Diagnostics.EventLog() Log.Source = "Demo Log" Log.WriteEntry("Hello World", EventLogEntryType.Warning)
It gives the following error message: The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security.Luai Alrantisi, BSc in Computer Engineering, University of Ottawa 2007, Canada. IT Manager of MTN Mobile Telecom.
I am trying to write disk errors to the system event logs.I have a list of errors reported to the event logs if disk issues occur.So i just want to write dummie errors to the logs so I can do testing.I am able to write to the logs but the description comes up as follows:
I am trying to make an application which logs on to a server using the telnet protocol runs a couple of commands and stores the output of these commands in a text file.The problem is that I cant really seem to figure out how to negotiate the telnet commands. I have done a packet capture of a telnet session todifferent servers using a packet capturing program and I dont seem to find any fixed pattern. Every server negotiates the command in its own different way and in a different sequence, moreover the commands exchanged are not the same.
What I want to do is to exchange the bare minimum commands which will allow me to log on to any server via telnet, run my commands, take the output and logout.I have searched the internet for such a set of 'general' telnet commands but I wasnt able to find any.
In my application, I've built an object that communicates with an OPC server and whenever the value of a certain OPC item changes, it logs all the OPC items to a database. This all works beautifully. However, I'm having a problem with disposing of the instances of this class. Whenever I want to remove an instance of this class from the application, I'm dereferencing the object (objDevice = Nothing) and letting GC take care of the rest. I've inserted breakpoints and am monitoring to ensure that the object is dereferenced (it is).
Problem is, even after the object has been dereferenced and is CONFIRMED to be equal to Nothing, the object is still logging data to the database. I'm still trying to get a handle on disposing of objects properly, but most everything I read tells me to dereference and let Garbage Collection take over.
Im trying to create a windows service with vb.net but when I run: InstallUtil.exe myservice.exe
I'm getting the following error in the MyService.InstallLog file: Restoring event log to previous state for source DebtorInvoiceMailingService.An exception occurred during the Rollback phase of the System.Diagnostics.EventLogInstaller installer.

I want to build an application, which can remote access to SQL Server in Server Machine.I used to build one, and it also can access to SQL Server in other pc. But when i promote it to become a Server(to become a Domain Controller). My application has never access to SQL Server. I don't know what to do now?
remember: I want to build an application, which is accessing to SQL Server in Window Server(Client/Server Application).
Is there a way in VB or C# to connect with a cellular modem (on my laptop) from my home machine and have it send me responses if I know it's IP address? Can't seem to find one, so I thought I'd ask.....
I have code to extract each entry in an event log. If the entry is after a set date (the value of my startDate variable) then it gets the information from the log and outputs to an email (I can do all this, the bit I am stuck on is as follows) I am currently using the following code extract:
i am trying to create a program to save all the event logs (Application,Security,System) and diagnostic files (No problems with this) from all the PC on my network .If possible i am trying to save as a csv or text file .
I've found a few examples of using vb.net to access an sql database, so far none of them have worked . They all involve using DataReaders. Maybe its the fact that the sql db is not on the same machine as the application.I was just wondering if anyone had a more comprehensive example of using VB.NET to access a remote sql server.
EDIT:I've received a few helpful comments an replies already. So far my connection string looks like: "server=sqlblah.myhost.com;uid=myuser;pwd=pass;database=testdb"
Probably also good to mention their is no editing of the tables a this point, just reading.
How can I connect to a database using sql server 2000 and stored in another PC with vb net (still in 1 LAN)?So that PC only stores the database, and another PC store the user interface and business logic.Is it related to the connection strings, on the datasource, we just put the IP address for that remote sql server?
