Can log to Screen/File and EventLog .DESCRIPTION Start by setting FilePath and/or EventLogName/EventLogSource. The values are stored in global variables and don't need to be set again. Call Write-ADFSTkLog with one or more parameters depending on how much logging needed. If a Warning is logged the following global variables will be changed: $Warnings will increase with 1 $LastWarning will be set to $Message If an Error is logged the following global variables will be changed: $Errors will increase with 1 $LastError will be set to $Message If -MajorFault is provided, EntryType will automatically be set as Error and after logging has been done, the Message will be thrown. If a variable namned $Silent is used and equals $true in the script calling Write-ADFSTkLog, no logging to screen will be done .EXAMPLE C:\PS> Write-ADFSTkLog -Message "Hello World!" 2012-02-02 16:40:16: Hello World! -Message parameter are not needed as long as the message is written first C:\PS> Write-ADFSTkLog "Hello World!" -EntryType Warning WARNING: 2012-02-02 16:41:23: Hello World!
