MSH Error message line number and Trap.

---

---

An Other issue that did cost me a lot of time was that if you trap an Error,
and there is an Error in the TRAP MSH will point you at the wrong place
(at the foreach, that had the trap in it.)

See example below.

as my function was a bit bigger,and I did not have the helper Writes ($_.name and "Trap") that I put in the Example to point me the way. ( WMI viewer script for MSH (GUI) ), It took me some time to find this out.

So don't make errors in your TRAP's !!!

PS I know that it is a bit ugly this way, but still the error is confusing.
(in productioncode I would check first and not Trap the Error)

$MC = new-object system.management.ManagementClass win32_share
$MOC = $MC.GetInstances()
$MOC  foreach {
  $_.name
  $null.name() = "Trap Me Please"
  trap{"Trap";$null.name() = "Find Me Please"}
}

E$

Trapforeach-object : You cannot call a method on a null-valued expression.
