# Level 14
[System.Reflection.Assembly]::LoadWithPartialName(''System.Drawing'')
$bm = [System.Drawing.Bitmap]::FromFile( 'C:\_spons\wire.png' )
$new = ...

This level was another "Interesting" task, It could have been solved quick and easy ... was it not for one little problem ....
Level 13 involved speaking to PHP web service with XMLRPC, I search for PowerShell and XMLRPC got me here :

For Level 12 more bitmaps but then mixed together and delivered as bytes :
# Level 12
$a=$b=$c=$d=$e = @()
$ba = [System.IO.File]::ReadAllBytes( "C:\PowerShell\PoshChallenge\evil2.gfx" )
foreach ($byte in $ba) {
$a += $byte
[void]$foreach.movenext();$b += $foreach.current
[void]$foreach.movenext();$c += ...

As I entered another level about bitmaps, I will reflect a bit more about the way of working with bitmaps in PowerShell instead of posting the solution only. ( if this info is to much of a spoiler for this level you cheated some levels anyway ;-) )
The level was called odd even and involved a distorted bitmap ( paste in solution from Posh ...

Level 10,
This one was easy as I knew the answer to the sequence so could just look how to script it, still was a nice exercise, ( can you solve the Sequence's logic by only looking at the PowerShell script ? ) :
you had to fill on this Sequence till 30 and then get the length for the solution : a = [1, 11, 21, 1211, 111221, ...

And another update at the PoSH Challenge front, I'm arrived at Level 20,(had to cheat a bit at level 17 to arive there but more about that later ) so some more posts will follow ;-)
I must say that the The Python Challenge. is really a great piece of work, complements to the composer(s) of this Challenge!!
For the average PowerShell user, ...

This one was very challenging and got me puzzling for way to deep into the night morning last Friday, taking much more time as expected.
The problem at hand at Level 8 did involve bzip2 , I started to find if there was a .NET library for this and found this one: .NET Zip Library #ziplib (SharpZipLib)
And Loaded the library into my ...

before I give my answer to this level of the Python challenge
I made a small PoSH version ,

For Level 6 I needed to get information from zip files not available from plain PowerShell, I decided to use a tool I had already handy 7Zip, that comes with a command line version (Instead of looking for a .NET DLL, you have to wait to level 8 for that ;-)
To make it a bit more usable in this Level I made a small wrapper function ( You ...
