Returning Events Logs Using WMI - ObjectQuery
Apr 15, 2010
I am working on a Visual Basic application that is returning Event Logs using WMI. I only want the latest 5 application, error events, but as I have the code now I get everything and then need to loop through and grab the first 5.
Dim wqlEventLogAs ObjectQuery =New ObjectQuery("SELECT * FROM Win32_NTLogEvent WHERE Logfile = 'Application' AND Type='Error'")
Dim objEventLogAs ManagementObjectSearcher =New ManagementObjectSearcher(myManagementScope, wqlEventLog)
ForEach objMgmtAs ManagementObjectIn objEventLog.Get
Next
I have tried a number of ways to add "Top(5)" to the query but each time I get "Invalid Query".

My (local, windows/mono) app logs important events to a text file. In case of a sudden crash/failure/forced exit, no data should remain unwritten (as far as it's possible). Thus I currently use a simple append-to-text-file approach:

I need to find all records where the status is in the local list of Integer's.
In SQL I would do
Where Status in (select i from my list)
But I can't figure how to make it happen in Linq.
ListData = New IssueTrackerEntities2()
Dim queryString As String = "SELECT VALUE CallList FROM IssueTrackerEntities2.CallList AS CallList"
Dim Status As New List(Of Integer)

I'm working on modifying this example:
Using advWorksContext As New AdventureWorksEntities
' Call the constructor that takes a command string and ObjectContext.
Dim productQuery1 As New ObjectQuery(Of Product)("Product", advWorksContext)
[code]....
An ObjectQuery can be enumberated only once. (Subsequent attempts at enumeration throw an exception.) The enumberation takes place in the for each statement. The problem is that if the query is empty attempting a For Each will throw an exception. But if I check for a count:If productQuery1.Count > 0 Then . . .
That eats up my one chance at enumeration. I could nest the For Each in a try/catch block and throw away the empty query exceptions, but that's ugly.

I put Label1.Text = Watch.Elapsed.Milliseconds And notice that it goes from 0 to 1000 milliseconds and then back to 0 starting over every time.Then I do some tests and put,[code]...
Whenever I press e, it logs the value in count and displays it.[code]....
This should end program once it hits 5 milliseconds.But the problem is it doesn't.On one of my test runs i notice it does end, but only after a little while. Does this mean VB has a hard time detecting the stopwatch or something?

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!!!)

Heres part of the code that 'grabs' each EMail:

I have a project using Application Framework and then a main form which displays the main UI. There's another form I call it frmLog, which is solely used for logging any operations internal message logging. By default, I created a Global MyApplication logging object called myLogger which is an object of type frmLog. In Application_StartUp, I instantiate it by myLogger = New frmLog. On the main UI form, there's a button Show Log which does myLogger.Visible = Not myLogger.Visible.

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.
