Problem accessing Application Event Log programatically

Helen Bull17-Jun-08 3:58

Hi, I have written a small Windows Service app in VB.Net (1.1) to monitor the event logs on my server (Windows Server 2003), and I have modified a couple of my existing apps to write to the Application Event Log.

The events are writing to the log OK (I can see them fine in Event Viewer). And the Monitor can see new events being logged in both the System and Security logs.

But it does not react to any events being created in the Application log, either from my own apps or any others.

Does anyone have any suggestions why this could be? I have coded the three event log instances just the same, yet only 2 out of 3 work as expected. Thanks in advance.

Well.. I've done something similar in the past and never had issues with it. The Application log is not really different so my best guess (without any code) would be a typo somewhere.

Do you have any errors it returns ? Or maybe an idea where in your code it happens ? Posting this would help a lot..

Meanwhile.. simple, little piece of code to list stuff in the eventlogger:

(console app)

dim elEvent as new system.diagnostics.EventLog("Application")
dim elEventEntry as System.diagnostics.EventLogEntry

for each elEventEntry in elEvent.Entries

console.writeline(elEventEntry.TimeGenerated.Tostring & " - " & elEventEntry.Source.Tostring & " - " & _
elEventEntry.Category.Tostring & " - " & vbcrlf & vbcrlf & elEventEntry.Message.tostring)

Thanks. I've now discovered that it is in fact managing to react to some events in the application log - I left it active overnight and it spotted some virus software log entries.

So the problem is actually not what I thought - it is reacting to some changes in the Application log, just not all of them.

I think I'll have to look more deeply into the difference between my events and the virus software ones to see where they differ.

Make sure you are on different sessions.. i think the default behaviour of the WebBrowser control inherits from Internet Explorer stuff ( probably).. and as I recall, while in the same thread or executable, sessions are shared. ( like in internet explorer when you open different tabs in the same browser)

hi all
i want to change the leftmost dimension of a two - dimensional array. but redim statement does not change the Left Most dimension. For example i declare a two-dimensional array as following
Dim WrappingItemInfo(0, 4) As String
after that i write following statement at particular condition
ReDim Preserve WrappingItemInfo(1, 4)
but above statement give error "'ReDim' can only change the rightmost dimension.".
so how can i change the leftmost dimension of an array ?

set WrappingItemInfo(1) to be a new array of four elements. This would work in C#, should work in VB.

sir,
thanks for your response but i does not properly get you
can you explain it bit more with code(whether in c# or vb)

one more thing. in my previous post, i simply give a example. In real condition, Leftmost dimension of an array is increased every time by one when a particular condition is found.

int [,] n = new int[5,5]();
n[0] = new int[5]();

something like that

You should use a dynamic collection instead of an array, like a List(Of String()).

An array can't be resized, so what the ReDim command does is to create a new array, and copy all data from the old array to the new array. It can get pretty expensive as the array grows...

Despite everything, the person most likely to be fooling you next is yourself.

Well, don't call it button1, for a start ( that's just dumb )

You have properties on the form for the AcceptButton and CancelButton. These set what buttons are pressed by Enter and Escape

Check Visible property of button it has to be true, to be sure of it you may also set this property on Form load event.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<appSettings>
		<!--   User application and configured property settings go here.-->
		<!--   Example: <add key="settingName" value="settingValue"/> -->

		<add key="timer.Interval" value="1000" />

		connectionString = "login=sde;Password=topology;Database=Tshwane_Valuations_Train;
		Server=SGIICORNETGS01"/>
		</connectionstring>
	</appSettings>	
</configuration>

and am Accessing this Connction string from the Vb App, like this

Dim constr As String = Configuration.ConfigurationSettings.AppSettings("Tshwane_Train")

When i compile the Application, i get no Errors ,but but when i try to run the application, i mean the Part that will need to Connect to the Database i get the Following Error.

An unhandled exception of

You might try something like this:

connStr = My.Settings.ConnectionString

Works for me.

At First i saw my e-mail with this Code from you

Public Sub initializeDataConnection()

        Dim strConn As String

        Dim settings As ConnectionStringSettings

        settings = ConfigurationManager.ConnectionStrings _
              (WindowsApplication1.My.MySettings.APPProdConnectionString")

        If Not settings Is Nothing Then
            strConn = settings.ConnectionString
            cn = New SqlConnection(strConn)
        End If

    End Sub

and when i click to go to CodeProject, i see a Different Answer, did you change it?

let us look at the above code, i understand what you are doing and in the Following line where you declare like this

Dim settings As ConnectionStringSettings

The ConnectionStringSetting is not recognised, am using VS2003 and VB(Windows App) is this Applicable to it?

Thanks

Your app.config has a seperate section for connection strings. Have a google.
