Access array data from command output, without a variable?

[Javik]

Is there some way to directly access array data that is output from a command without storing that data into an array datatype first?

Basically, the command normally outputs data in array format, and I only need a single cell's worth of data from its output, and the rest can be discarded immediately after grabbing what I need.

Normal:

#Include <File.au3>
Local $Foo = _FileListToArray( "C:\" )
ConsoleWrite ($Foo[1] & @CRLF)

Arrayless?

#Include <File.au3>
ConsoleWrite (_FileListToArray( "C:\" )[1] & @CRLF)

Error: Syntax error

javik,

No.

It just looks so.... unoptimized like that, though.

; Get user's properties from Active Directory
    Local $ADGOPTmp
    $ADGOPTmp = _AD_GetObjectProperties(@UserName,"givenName")
    Local $FirstName = $ADGOPTmp[1][1]
    $ADGOPTmp = _AD_GetObjectProperties(@UserName,"sn")
    Local $LastName = $ADGOPTmp[1][1]
    $ADGOPTmp = _AD_GetObjectProperties(@UserName,"homedirectory")
    Local $HomePath = $ADGOPTmp[1][1]
    $ADGOPTmp = _AD_GetObjectProperties(@UserName,"profilepath")
    Local $ProfilePath = $ADGOPTmp[1][1]

javik,

Arrays are not one of AutoIt's strengths.

But you could always write a small wrapper function like this (untested):

; Get user's properties from Active Directory
Local $FirstName = _GetProps(@UserName, "givenName")
Local $LastName =  _GetProps(@UserName, "sn")
Local $HomePath =  _GetProps(@UserName, "homedirectory")
Local $ProfilePath =  _GetProps(@UserName, "profilepath")

Func _GetProps($sUserName, $sProperty)
    Local $ADGOPTmp = _AD_GetObjectProperties($sUserName, $sProperty)
    Return $ADGOPTmp[1][1]
EndFunc

Looks a bit more elegant that way.

Can't you copy and edit _AD_GetObjectProperties() so it doesn't create the array, just return the needed value?

The type of side effect you want where a temporary is created on assignment or as a result of a constructor is common to c++ type OOP languages. In scripting it's more of a C# thing.

In c/c++ circles those things are cool. In some other languages they are considered bugs waiting to surface.

But for c based it's really designed from the beginning. while(c = *p++) the while evaluates the side effect of the assignment to 'c' to see if it's a zero/NULL whatever, to stop the loop.

Use

; Get user's attributes from Active Directory
Local $FirstName = _AD_GetObjectAttribute(@UserName,"givenName")
Local $LastName = _AD_GetObjectAttribute(@UserName,"sn")
Local $HomePath = _AD_GetObjectAttrbibute(@UserName,"homedirectory")
Local $ProfilePath = _AD_GetObjectAttribute(@UserName,"profilepath")

_AD_GetObjectAttribute only returns a single attribute and does note "decode" data (e.g. convert date into a readable form).

And if you want/need to stick with _AD_GetObjectProperties then use:

; Get user's properties from Active Directory
Local $ADGOPTmp
$ADGOPTmp = _AD_GetObjectProperties(@UserName,"givenName,homedirectory,profilepath,sn")
Local $FirstName = $ADGOPTmp[1][1]
Local $LastName = $ADGOPTmp[4][1]
Local $HomePath = $ADGOPTmp[2][1]
Local $ProfilePath = $ADGOPTmp[3][1]
