Thanks in advance

You can specify the size in the registry under the event log entries. For
instance to change the size of the app log you would change the key


Which is a DWORD

Have you tried using FileLen?

Private Const MAX_PATH = 260
Private Declare Function GetSystemDirectory Lib "kernel32" Alias "GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long

Private Sub Command1_Click()
Dim strBuff As String, strSysDir As String
strBuff = Space$(MAX_PATH)

GetSystemDirectory strBuff, MAX_PATH
strSysDir = Left$(strBuff, InStr(strBuff, Chr$(0)) - 1)

MsgBox FileLen(strSysDir & "\Config\AppEvent.evt")

End Sub

Thanks vinnyd!
I can work with this.
Is there a way I can check the maximum file size that was set on the eventviewer?

If not I can use your input, and specify my own file size to make sure it doesn't go over..
