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"
$IE
$IE|Get-Member
PS> $object = New-Object -COMObject "InternetExplorer.Application"
PS> $object

Application          : System.__ComObject

Is it possible to use powershell via command line?

I tried doing it adding $IE = New-object -ComObject "InternetExplorer.Application" as an argument but get ..

"Invalid assignment expression. The left hand side of an assignment operator nee

ds to be something that can be assigned to like a variable or a property."

It is possible AFAIK. From the top of my head: Use '-command $IE = New-object -ComObject "InternetExplorer.Application"*

powershell -command "$IE = New-object -ComObject InternetExplorer.Application; $IE|Get-Member"

or

powershell -command "$IE = New-object -ComObject 'InternetExplorer.Application'; $IE|Get-Member"

work pretty well.

Yep, that's it, cheers.

$Read = ""

$iPid = Run(@SystemDir & '\WindowsPowerShell\v1.0\powershell.exe -Command $SW = New-object -ComObject  "Shell.Explorer.2"' & @CRLF & '$SW' & @CRLF & '$SW|Get-Member', "", @SW_HIDE, 0x2 + 0x4)

While ProcessExists("powershell.exe")
    $Read &= StdoutRead($iPid)
WEnd

ConsoleWrite($Read)

A bit shorter:

$Read = ""

$iPid = Run(@SystemDir & '\WindowsPowerShell\v1.0\powershell.exe -Command $SW = New-object -ComObject "Shell.Explorer.2";$SW;$SW|Get-Member', "", @SW_HIDE, 0x2 + 0x4)

While ProcessExists("powershell.exe")
    $Read &= StdoutRead($iPid)
WEnd

ConsoleWrite($Read)

While ProcessExists("powershell.exe")
WEnd
