Hello
T he atheist rejects the claim that there is a
supernatural entity or force that interacts with existence...
Because it is a claim without basis.

Atheism makes no claims whatsoever.
Atheism asserts nothing.
Atheism IS NOT an act or an action
IT IS a position
 It has no objective.
Comparatively / Conversely:
Anti-theism IS an act or an action
 It IS NOT a position
 It has an objective.
Not all ATHEISTS are ANTI-THEIST.
All ANTI-THEISTS are ATHEIST.

iText / iTextSharp / Powershell / checkboxes

Some cryptic notes related to how 'Checkbox' values are addressed when using iText / iTextSharp, .NET PDF library - To automate filling in PDF forms.

I wasn't able to find any information on how to fill in a checkbox on a PDF form, when using iText in Powershell.
So, hopefully this blog entry will help others.
HINT: the value is 'On'

Anyway - This is a decent example (I hope) -

The 'break' just stops the script.
After that, is the mechanics of how I figured out what value needed to be used for the 'check-boxes' on the form.




$TimeStamp = Get-Date -UFormat %b_%d_%H_%M

## NOTE - The DLL files need to be 'UNBLOCKED' before they will load / run. This has to be done manually or by using the Unblock-File command
## Run as admin...
#Get-ChildItem -recurse "C:\Powershell Stuff\itextsharp-all" | Unblock-File #-WhatIf

## And this module is needed, in order to use the actual .NET library - So Import it.
Import-Module –Name "C:\Powershell Stuff\PdfForm.psm1" -Verbose
