How to create Windows EventLog source from command line

Question

I m creating an ASP NET application that will log some stuff to Windows EventLog  To do this an event source has to be created first  This requires administrative priviledges so I cannot do it in the ASP NET app   Is there an existing command-line application that is bundled with Windows that can create an event log source  or must I roll out my own

You can also use Windows PowerShell with the following command:

if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {
    [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
}

Make sure to check that the source does not exist before calling CreateEventSource, otherwise it will throw an exception.

If someone is interested  it is also possible to create an event source manually by adding some registry values   Save the following lines as a  reg file  then import it to registry by double clicking it   Windows Registry Editor Version 5 00   HKEY LOCAL MACHINE SYSTEM CurrentControlSet services eventlog Application YOUR EVENT SOURCE NAME GOES HERE   EventMessageFile   C   Windows  Microsoft NET  Framework64  v4 0 30319  EventLogMessages dll   TypesSupported  dword 00000007   This creates an event source named YOUR EVENT SOURCE NAME GOES HERE

Try PowerShell 2 0 s EventLog cmdlets  Throwing this in for PowerShell 2 0 and upwards    Run New-EventLog once to register the event source   New-EventLog -LogName Application -Source MyApp  Then use Write-EventLog to write to the log   Write-EventLog      -LogName Application      -Source MyApp      -EntryType Error      -Message  Immunity to iocaine powder not detected  dying now       -EventId 1

However the cmd batch version works you can run into an issue when you want to define an eventID which is higher then 1000  For event creation with an eventID of 1000  i ll use powershell like this    evt new-object System Diagnostics Eventlog    Define Logbook      evt Source    Define Source     evtNumber Define Eventnumber  evtDescription    Define description     infoevent  System Diagnostics EventLogEntryType   Define error level  evt WriteEntry  evtDescription  infoevent  evtNumber     Sample    evt new-object System Diagnostics Eventlog    System      evt Source    Tcpip     evtNumber 4227  evtDescription    This is a Test Event     infoevent  System Diagnostics EventLogEntryType   Warning  evt WriteEntry  evtDescription  infoevent  evtNumber
