Array 1 has the host names and array 2 has the IP addresses. I tried using a for each loop but I can't figure out how to get the information from the second array into the loop. I then tried a regular for loop and then a do loop, but I can't get the code to work with the values for the second array. Any help would be appreciated. Hi,

now one thing i don’t understand, $app_dll.get_item($dll) produces results without the change but why dosen’t $app_dll[$dll] produce anything ?
thanks

when i print out $app_dll instead of showing
def abc
it shows
{def} {abc}

I have a problem to get value from Hash:
####################
#Create hash
$App_dll=@{}
#define string
$Hyrarchy=”ABC\def”
$temp=$Hyrarchy.split(’\’)
#devide the string
$App=$temp[0].split()
$dll=$temp[1].split()

#Update Hash Table
$App_dll.Add($dll,$App)

$dll
$a=”def”
$b=$App_dll.Get_Item($a)
###################################
The problem is that $b contains nothing

Hi,
About moshe’problem :
You’ve to assigne the data type to variables, like this casting :
[String]$App=$temp[0].split()
[String]$dll=$temp[1].split()

Without this you can’t Update Hash Table
$App_dll.Add($dll,$App)
-> because $dll and $App was System.Array in your first script…

Can you add this (write hash to a file) to your hash-section, I would appreciate this! THanks Carl Hi,

Great tutorial to get up to speed in a quick and efficient way! Thanks! The samples for working with arrays don’t seem to be completely correct?
$strComputers = “comp 1″, “comp 2″ defines an array, but $strComputers = @{“comp 1″ = “Dell”} is defining a hashtable?
