Try, catch : doing something if the TRY completed successfully

问题

I am looping through a list of samaccountnames and performing several actions:

# Disabling user
try {    
    Disable-QADUser $user | Out-Null
} catch [exception] {
    "Disable-QADuser: " + $($_.Exception.Message) | out-file $logfile -append
    write-host " - Error disabling useraccount." -fore yellow
}

# Set informative description
try {    
    Set-QADuser $user -Description "Disabled $now"  | Out-Null
} catch [exception] {
    "Set-QADuser: " + $($_.Exception.Message)| out-file $logfile -append
    write-host " - Error setting informative description in AD." -fore yellow
}

But how do I output something if the command completed successfully? Something like

write-host "User $user disabled"
"User $user disabled" | out-file $logfile -append

All help/pointers are greatly appreciated!

EDIT I noticed that I can use tee-object to send the output to file as well as console.. This way I do not have to have to lines to "tee" the output:)

Probably showing my ignorance here (I know nothing about power-shell, sorry - don't down vote me!). But if it's anything like java, you'd just place it underneath the line you are trying to execute:

try {    
    Set-QADuser $user -Description "Disabled $now"  | Out-Null
    write-host "User $user disabled"
    "User $user disabled" | out-file $logfile -append
} catch [exception] {
    "Set-QADuser: " + $($_.Exception.Message)| out-file $logfile -append
    write-host " - Error setting informative description in AD." -fore yellow
}

One important thing to keep in mind: if for some reason disabling the user didn't work, your catch block WILL NOT invoke since the error is not a terminating error. To change the type of the error to terminating error, use the ErrorAction parameter:

Set-QADuser $user -Description "Disabled $now" -ErrorAction Stop | ...
