View 2 RepliesI'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!!!)

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 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.
Is there an easy way to export remote event logs FROM an XP machine?

I am using VS studio 2010 to build a asp.net (framework 4.0) website. My code behind is in VB.Net, My testing browser is Firefox (latest version), also tested on IE8 and Google Chrome, same behavior.Basically I have a LinkButton in a DataRepeater in a UpdatePanel.The _ItemCommand event DOES FIRE for as long as I use the page regularly (every few minutes or so).
The problem is this: When I open another webpage (in another browser tab) and sit on it for like 1 hour or so and then come back to test page in the browser tab and click on the LinkButton, no event is fired and the page gets a reload. Like if the button had just died on me.I first tough it might be a Session TimeOut issue but I logged the SessionID in a text file and the Session DOES NOT expire. <<<< Using new method for detecting TimeOut
I can confirm (logfiles) that the root of my problem is that the _ItemCommand event simply stops firing. I just have no idea why it does.I have tried most solutions proposed under similar problems (event not firing) but my problem is positively different because my event DOES fire... Only for a limited time.
My Repeater ViewState is enabled.I have tried changing the LinkButton for a Button but no joy same problem.I have tried the uping the AsyncPostBackTimeout of the ScryptManager... no joy either.I have tried sessionState mode="StateServer".I have tried disabling my AVG Link Scanner.Here is the code I'm now using to check for Session Timeout:
If Context.Session IsNot Nothing And Context.Session.IsNewSession _
And Page.Request.Headers("Cookie") IsNot Nothing _
And Page.Request.Headers("Cookie").IndexOf("ASP.NET_SessionId") >= 0 Then

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.

I have a windows Forms app that displays data as it scans.Once you alt-tab or remove "focus" from the app and doing something else (open word) it stops updating. In otherwords it looks like the app has locked up.But it will finish the scanning as normal.But any updates from the scans being shown on the app window are not shown, that is until the app is finished and catches up.

I have an application I run on a netbook that is folded up inside a robot.Occasionally, something from the system tray will pop up unexpectedly. This removes the focus from my application I also thought there was a way (in forms properties in the vb6 days) that would allow to "run when minimized"? In short, I want this application to be running and nothing (asides an application error message) else getting in the way.

I'm trying to implement a boolean flag into a button so that when the button is clicked the flag will equal to true. After that i need to run an if statement stating that if the button is clicked then move/relocate the button to the corner of the screen. I tried setting my flag as true and using an IF statement but it didnt work. i get a syntax error stating "Operator '=' is not defined for types 'System.Windows.Forms.Button' and 'Boolean'
here's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Button1 = flag1 Then
Button1.Location = New Point(651, 511)
End If
End Sub
