.SYNOPSIS
Search for aircraft photos on Airport-data.com by the aircraft's registration number

.DESCRIPTION
This simple GUI script allows you to enter an aircraft registration and then search Airport-data.com for photos and specifications of that aircraft.
Interactive usage: enter an aircraft registration in the input texbox and press Enter or click the Search button to search Airport-data.com's website for photos and detailed specifications.
Command line usage: run this script with -Help parameter to view its command line syntax.

.NOTES
Dashes are mandatory in many aircraft registrations, but not all, e.g. PH-PBY and N1944S will work, but PHPBY and N-1944S won't.

Invalid command line switches starting with a dash will trigger a PowerShell error message.

All command line switches starting with a slash will trigger this script's help screen.

This script can be extended by using downloaded local aircraft registration databases; see this script's web page (see links section) for details.

Return code ("ErrorLevel") is 1 in case of errors, otherwise 0.

.PARAMETER AircraftRegistration
(optional) A valid aircraft registration, e.g. PH-PBY or N1944S or OK-NUL.
Aircraft registration may be entered in the GUI if not specified on the command line.

.PARAMETER SearchEngine
(optional) Alternative search engine if no match was found on Airport-data.com.
Valid SearchEngine values are 'DuckDuckGo', 'Google' (default) or 'StartPage'.
Useful only if local database extension scripts are installed.
Command line only, cannot be changed interactively in the GUI.

.PARAMETER Hide
Hides the console window (GUI remains visible).
Command line only, cannot be changed interactively in the GUI.

.PARAMETER Debug
Shows some progress messages, especially usefull when using local databases.
Command line only, cannot be changed interactively in the GUI.

.PARAMETER Version
Show this script's version number.
If combined with -Verbose show full script path, version number and last/modified/release date.

.PARAMETER Help
Shows this script's help screen, with more details than the Help button's help text.

.EXAMPLE
powershell . ./AirRegGUI.ps1
Will open the GUI with empty input textbox, the console remains visible

.EXAMPLE
powershell . ./AirRegGUI.ps1 -Hide
Will open the GUI with empty input textbox and hide the console

.EXAMPLE
powershell . ./AirRegGUI.ps1 N1944S
Will open the GUI with N1944S in input textbox, and start search immediately, the console remains visible

.EXAMPLE
powershell . ./AirRegGUI.ps1 -AircraftRegistration N1944S
Will open the GUI with N1944S in input textbox, and start search immediately, the console remains visible

.EXAMPLE
powershell . ./AirRegGUI.ps1 PH-PBY -Hide
Will open the GUI with PH-PBY in input textbox, start search immediately, and hide the console

.EXAMPLE
powershell . ./AirRegGUI.ps1 -AircraftRegistration PH-PBY -Hide
Will open the GUI with PH-PBY in input textbox, start search immediately, and hide the console
