Saw you were repeating asterisks a lot; a simpler way to do that is:

$('*'*[times-to-repeat])

example:
$stars = $('*'*5)
1..15|%{"{0}{1,10}`+ {0} `+{1,-10}{0}" -f $stars,$_}

Great stuff, though!

Yes, this is the "easier" way to do things. If you're looking for full control of the PowerShell engine, then one should be looking to create a "custom host".

Great post. Lots of important information.

One more thing to note is that, in PS 3.0, Get-Help -Online works even if you don't have help files on the computer.

Separate downloads like that have always been a bugbear of mine - I always loved Mark Russinovich's approach with the Sysinternals programs: one file to download/store, whether you're 32 or 64 bits, whatever version of Windows.

The 32-64 bit duality is hard to accommodate within an MSI, frustratingly, but supporting two versions of Windows with one MSI shouldn't be too hard surely.

Some good examples here!

As someone still learning I wish you hadn't used the alias % in examples. It's confusing to read.

Adding some examples of how to format in HTML would also be cool.

No need to take care once you understand the history of the operators.

They were first used extensively in 'C" lqnguage. The pre and post use have a very specific and desired effect that we use all of the time.

Try the following and you will immediately see the difference.

$lc=0;1..10 | foreach {"Loop counter:" + $lc++ }

$lc=0;1..10 | foreach {"Loop counter:" + ++$lc }

Look closely at the output. If you only print teh counter after the loop has finished it will always appear to be 10 but outside the loop we have incremented one extra time with post increment. That is because post-increment increments teh counter AFTER the couter has been printed inside the loop. IN most cases we want this behavior.

for($i-0;$i -lt 10; $i++){....}

With ++$lc we increment before we print and the ending counter is always the same as the last one printed.

Here is one explanation of the operators: Pre-Post OPerators

They are very useful once you understand how they work.

2011-12-13T01:27:16.583Z

That's exactly how C/C++ and related languages have had ++ implemented as well for a couple decades or more now, I'm sure PowerShell's designers/thinkers/implementers were just conforming to that spec.

2011-12-12T16:26:30.834Z

That's not just a PowerShell curiousity...it's how ++ and -- work in many languages. If you use them before the variable, the increment/decrement happens and then the new value is returned. If you use them after the variable, the current value is returned, and then the increment/decrement happens.

Isn't the pipelined foreach CmdLet 20 times
2011-11-10T19:05:49.476Z
Isn't the pipelined foreach CmdLet 20 times slower than the foreach statement?

One way to speed up a 'foreach' in a pipeline is to use a scriptblock with a process block (&{process{'code here'}})

In this example, the scriptblock takes about 1/10th of the time as the ForEach-Object CmdLet.

'{0} ms' -f (Measure-Command { 1..10000| foreach { $_$_ } }).TotalMilliseconds
'{0} ms' -f (Measure-Command { 1..10000| &{process{ $_$_ }} }).TotalMilliseconds

614.3745 ms
62.1588 ms

One caveat to the scriptblock method is that it executes in a child scope. This can be worked around by dot-sourcing the scriptblock, but this is a little slower.

'{0} ms' -f (Measure-Command { 1..10000| . {process{ $_*$_ }} }).TotalMilliseconds

96.4542 ms

2011-10-10T22:53:54.592+01:00

A little further, but still not quite successful. I managed to get the first DLL to register and the alias defined, but InstallUtil still gives me the "built with a newer version" error.

For the record, I discovered another powershell.exe in C:\Windows\SysWOW64\WindowsPowerShell\v1.0\ which is run from the start menu (and gives the command window with the blue background) I had to add the config file there as well.

2011-10-07T19:50:00.508+01:00

@Karl

I'd double check the .config file is typed correctly and is in the same folder as the .exe. When .NET loads an .exe file, it checks the .config file for things to do - like bind to a different version of .NET than was originally planned.

Updating the .config file should work - the only things I can think of are typos...

2011-10-07T19:47:03.396+01:00

@Paul
Yes - that is probably the case. In order to fix that, you need to create a config file for the remoting exe target (wsmprovhost.exe).

I've not tried it, but I would imaging creating a wsmprovhost.exe.config with the same contents would solve the problem.

I can't get your fix to work. When I try to r...

2011-10-07T19:14:08.297+01:00

I can't get your fix to work. When I try to run the "Add-Type" command, I get the same message after adding the config file (and restarting PowerShell). Can you suggest anything I could try? I build and addin with Visual Studion 2010, and it is using the 4.0 framework.
