Ok, Ok, So I installed VS Community, recreated my UI, and got it running from
ISE. What took about 1000 lines to build in Forms only took about 75 lines in
XAML. You convinced me.
I had an issue with the select node code, but after messing around with it I
ended up taking “[@Name]” out since you’re getting the $_.name property in the
foreach. So mine works looking like this:
$xaml.SelectNodes('//*') | Foreach-Object { Set-Variable -Name ('Window' + '_'
+ $_.Name) -Value $Window.FindName($_.Name) }
Which is fine, it makes all the variables like I expect them to. With the
[@Name] in there it didn’t return any results.
Got my “Cancel” button closing the form too, and populated some of my pull
downs. Now the real work begins…
I can pretty much lift all the functions and actions for all the buttons and
pulldown elements from my original code to this, changing the names of the
variables of course, right? Basically I can get it working the same way it’s
working now, just with WPF instead of forms?
With all the stuff I do, I have a text box for output when users select things
in pull downs and click buttons, how do I append text to my output text box if
it’s in the XAML? Or is that the same too, I just do
$window_textboxOutput.appendtext((“stuff”))? It didn’t seem to work.
I do want to runspace some things. I pretty sure I will have to do the binding
bit you talked about if I thread a button action that writes output to the
output text box, right?
Fantastic series of post too, thanks much for writing them. I’m excitd to try
threading stuff, but I should probably get a handle on WPF I guess first..
Thanks Ryan, and if at any point this is too much for the list I’m happy to
take it offlist if you have the time.

Windows forms, by hand. (I really need a copy of visual studio or powershell
studio, or something.. ☺ )
Thanks so much guys. I had totally forgotten about this list until I saw the
error handling thread. I’d found http://poshcode.org/5520 and got some of that
to work, partly. I’ll start looking through these in earnest, but it looks
like exactly what I need. my ui is pretty complicated and lots of elements do
or don’t do things depending on data in other elements, so I’m not sure how it
will go, but I’ll give it a try.
Xaml looks somewhat simpler to write, but I’ll save that for another day. ☺

Subject: Re: [powershell] GUIs and runspaces
Is this WPF or Windows Forms?
When I started writing WinForms, this blog post helped me learn about different
runspaces and how to make the forms more responsive:
https://www.sapien.com/blog/2012/05/16/powershell-studio-creating-responsive-forms/
If you are doing it in WPF, I have a series of posts on UI development:
http://www.ephingadmin.com/better-know-a-powershell-ui/
The "Quack like a duck" post talks about different threads and uses PoshRSJob
(3rd party cmdlet on GitHub) to do the threading.
Boe Prox (the author of PoshRSJob) has a lot of good information on this also.
Here's a post about writing data from one thread to another:

Let me know if you need any other resources!

So I've written a fancy PowerShell script and given it a GUI and it works
great. As I add more features to it though, I find that it’s taking longer and
longer to run and thought I would try to get it to run in a separate thread to
free up the GUI. I’m not finding many resources to help me learn how to do
that. Can anybody point me to any? I know about sunspaces, bur have not had
any luck with getting them to work. Help?
