Looky, looky! Custom sensitive information types with even more customitivity!

You can do most of the effort of creating a data classification here, although if you want to use any of our built in functions (such as credit card Luhn check), you’ll need to export/modify/import, use the sensitive information type package that I created (referenced earlier) or use one of our native DLP classifications.… [ Continue reading ]

Testing a variable with the value of zero

Tonight, while working on my previous script, I ran into an interesting problem when testing the presence of a value.

Consider this:

PS C:\> [int]$IntValue0 = 0
PS C:\> [int]$IntValue1 = 1
PS C:\> [string]$StringValue0 = "0"
PS C:\> [string]$StringValue1 = "1"
PS C:\> $IntValue0
0
PS C:\> $IntValue1
1
PS C:\> If ($IntValue0) { "exists" }
PS C:\> If ($IntValue1) { "exists" }
exists
PS C:\> if ($StringValue0) { "exists" }
exists
PS C:\> if ($StringValue1) { "exists" }
exists
PS C:\> if ($IntValue0 -eq $null) { "null" }
PS C:\> if ($IntValue0 -lt 1) {"less than 1" }
less than 1
PS C:\> $IntValue0.GetType()
