Im looking for practical applications of this. Any caveats?

I did not see caveats yet. What do you mean 'GOOD' example? Is this one good?

for($i = 1; $i -le 100; $i++ )
{
write-progress Updating progress -perc $i;
for($j = 1; $j -le 100; $j++ )
{
write-progress Secondary progress -perc $j -id 1; sleep -m 10
}
}

Thanks,

If you go to Mow's tab completion
blogentry(http://mow001.blogspot.com/2006/06/p...on-part-4.html)
, "TabExpansion" function uses "write-progress" while caching type
information.


And
"http://img.photobucket.com/albums/v138/dance2die/powershell/progressbar.jpg"
that is how it displays(it will display a bit different when you use Mow's
tab completion function, no type name information will be displays but only
progress bars)

Two progressbars display how much of type caching has been performed...

here are a couple:
the first is a basic view of progress - it's kind of cute:

$r = new-object system.random
for ( $perc = 0 ; $perc -le 100; $perc += ( $r.next(1,10)) )
{
foreach ( $id in 01,02,03 )
#,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20 )
{
write-progress ("Activity: {0,2}" -f $id) "Active $id" $id -perc
$perc
start-sleep -mi 100
}
write-progress "SubActivity: 12" "Active 12" 21 -perc $perc -parentid 12
start-sleep -mi 100
}
write-progress "SubActivity: 12 - now sleeping for 3 seconds" "Active 12"
21 -perc 100 -parentid 12
start-sleep 3

This next script gets all the methods from all the types in the current
process and returns a big honking hash table - it shows another way to use
progress:

# Get-Methods.sp1
$hash = @{}
$asms = [appdomain]::currentdomain.getassemblies()
$asms | foreach { $cur = 1 } {
trap { continue }
$perc = [int](( $cur / $asms.count ) * 100)
$name = $_.getname().name
write-progress "Getting Types from $name" Active 0 -perc $perc
$_.gettypes() # push the types down the pipeline
$cur++
} |
foreach {
trap { continue }
$name = $_.fullname
$hash.$name = $_.GetMethods()
}
$hash

PS> $hash = Get-Methods
PS> $hash."System.Object"|%{"$_"}
System.Type GetType()
Int32 GetHashCode()
System.String ToString()
Boolean Equals(System.Object)
Boolean Equals(System.Object, System.Object)
Boolean ReferenceEquals(System.Object, System.Object)

Thanks James... Im just trying to wrap my mind around this concept. I think
your example helped.

The second example also gives us very interesting statistics on the 'power'
that is included in PowerShell... ;-)

PS> $hash.count
10080

PS> $hash.keys | %{$c = 0} {$hash[$_] | %{$c++} } {"count: $c"}
count: 175367

PS> 175367 / 10080
17,3975198412698
