Write message in text box with try catch on if - textbox

Question

I would like a message to appear in a text box. The checked box indicates witch folder to copy to another directory. I would like a message to appear in the text box depending on if the copied folder as succeed or failed (error example : if the folder does not exist). At that point, i've tried with TRY CATCH, however, i can't figure out where to put my stuff so it wont erase the previous message or duplicate messages. Note, you can check UP TO 6 check boxes. So at the end i'm supposed to have 6 messages.
Look at Tab1BTNcreation at the bottom. Thank you !

Answer 1

Actually, i did this in my button (and will continue for all my IFs). I just copied the end of the code.
$Tab1BTNcreation.Add_Click({
$SelectionCBB1 = ($Tab1CBB1.SelectedValue)
$SelectionCBB2 = ($Tab1CBB2.SelectedValue)
$SelectionCBB3 = ($Tab1CBB3.SelectedValue)
$SelectionTB4 = ($Tab1TB4.Text)
$Tab1TBmessages.Clear()
$SelectedPathBin = "$pathDE\$SelectionCBB1\sets\$SelectionCBB2\Bin2"
$SelectedPathVers = "$pathVERS\$SelectionCBB3\$SelectionTB4"
New-item -ItemType Directory -Path "$pathVERS\$SelectionCBB3" -Name "$SelectionTB4"
If ($Tab1CBbin.IsChecked -eq $true) {
$TestPath1 = Test-Path $SelectedPathBin
$TestPath2 = Test-Path $SelectedPathVers
If ($TestPath1 -eq $True -and $TestPath2 -eq $True) {
copy-item -Path $SelectedPathBin -Recurse -Destination $SelectedPathVers
$Tab1TBmessages.AddText("Dossier Bin : Copié`r`n")
}
else {$Tab1TBmessages.AddText("Dossier Bin : Non copié `r`n")
}
} (......)
