Clearing Application log programmatically

I have trouble with Application Log in Event Viewr because it constantly gets filled up. What I want to do is to build a utility that would clear the application log whenever it gets filled. I don't want to re-invent the wheel so I was wondering if anyone have done something like this before and what is the best way to approach this problem.

you will want to run this vbs script as a scheduled task every so often.  Just copy the code into notepad and save with a .vbs extension.  Then from your task scheduler call it at specific intervals.
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
 & "{impersonationLevel=impersonate,(Backup)}!\\" & _
 strComputer & "\root\cimv2")
Set colLogFiles = objWMIService.ExecQuery _
 ("SELECT * FROM Win32_NTEventLogFile WHERE LogFileName='Application'")
For Each objLogfile in colLogFiles

Open in new window

more information on scripting event logs can be found here (like for logs that meet specific conditions, backing them up before deletion, etc.)

You can set the properties of Application event log to over write events "Over write events as needed (oldest events first)" this will cause the events to be overwritten when it reaches the specified size.
Goto event viewer > Properties of Application events > change the settings here
