Answer 1

Just for clarification, you want to click this button and have this event run continuously rather than just the 1 time it happens? If that is the case, then you can just use a While statement:
While ($True) {
#Do Stuff
If you wanted to stop this action, you would need something else instead to stop the action (not tested but might work):
$btn.Add_Click({
If ([bool]$Script:Run) {
$Script:Run = $False
} Else {
$Script:Run = $True
While ($Script:Run) {
#Do Stuff
The other issue is that this is happening on the UI thread and will probably cause some performance issues (UI lockup) so you may want to look at some sort of multithreading to take the load off of the UI.
