Power shell script with GUI performs slowly - winforms

Question

I have created a gui with powershell that allows me to copy files from inside folders into one place .
Example you have a folder A and in folder A there is Folder B and C inside all these folders you have a bunch of logfiles named logfile + date.log
My app can hunt through all the folders and move copy the log files to a single location.
The script works but when it is getting a list of files to copy it is slow and says "Not responding" at the top of the window next to where it says "Copy Files To One Directory"
I have added the script can you guys have a look and let me know how to speed it up.
The functions it hik are causing the problem are after the "These are the function I seems to be having a problem with"
Thank for the help.
The code

Answer 1

"Not Responding" means the thread isn't waiting for windowing input (in your example the thread is running the powershell code). I don't think there is a trivial way to create new threads in Powershell. However, you might be able to make your GUI more responsive using PowerBoots and powershell jobs like in this example.

Answer 2

You are declaring local variables inside a function (Call-MainForm_pff) and using these variables in other function. That will not work. See sample code. Only $Var2 will be displayed.
#=================
Function One-Set-Value {
$Var1 = "This is a test."
}
Function Two-Display-Value
{
$Var2 = "This is a second test."
Write-Host "Var2" $Var2
Write-Host "Var1" $Var1
}
One-Set-Value
Two-Display-Value
#=================
Convert these variables in to functions. This will work with return values.
