Just for the records:
MS provides an easy method to retrieve the methods, properties, events of COM objects by using PowerShell.
Open powershell.
Create the object. The syntax is:
$variable = New-object -ComObject "ProgID"
Type the variable name to retrieve the properties of the object
Use "Get-Member" to retrieve all properties, methods, collections and events of the object
Example:
$IE = New-object -ComObject "InternetExplorer.Application"
