Capturing unhandled exceptions

I am trying to catch a unhandlled exception that powershell produces using windows forms;

Currently I am able to capture terminating errors using try/catch and have researched several post and still it shows the unhandled exception error box, which I would like to not show up.

Try Catch, doesn't seem to help

Function Get-Choice{
Try{
$ErrorActionPreference = 'Stop'
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")

[void][System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")

$Form3 = New-Object System.Windows.Forms.Form

$Form3.Text = "Please Make A Choice From Below"

$Form3.ClientSize = New-Object System.Drawing.Size(390, 160)

$form3.topmost = $true

$Text = New-Object System.Windows.Forms.Label

$Text.Location = New-Object System.Drawing.Point(15, 15)

$Text.Size = New-Object System.Drawing.Size(300, 80)

$Text.Text = "What would you like to do today? `n`n 1. Find the Permissions of a folder `n 2. Find Who Has Access to a Folder `n 3. Find out what shares are on a server`n 4. Select a csv that contains a list of shares"

$Form3.Controls.Add($Text)

#$ErrorActionPreference = "SilentlyContinue"

Function Button1

{

$Button1 = New-Object System.Windows.Forms.Button

$Button1.Location = New-Object System.Drawing.Point(15, 100)

$Button1.Size = New-Object System.Drawing.Size(125, 25)

$Button1.Text = "1. Folder Permissions"

$Button1.add_Click({Folder

$Form3.Close()})

$Form3.Controls.Add($Button1)

}

Function Button2

{

$Button2 = New-Object System.Windows.Forms.Button

$Button2.Location = New-Object System.Drawing.Point(145, 100)

$Button2.Size = New-Object System.Drawing.Size(100, 25)

$Button2.Text = "2. Folder Access"

$Button2.add_Click({Members 

$Form3.Close()})

$Form3.Controls.Add($Button2)

}

Function Button3

{

$Button3 = New-Object System.Windows.Forms.Button

$Button3.Location = New-Object System.Drawing.Point(250, 100)

$Button3.Size = New-Object System.Drawing.Size(130, 25)

$Button3.Text = "3. Shares on a Server"

$Button3.add_Click({Shares 

$Form3.Close()})

$Form3.Controls.Add($Button3)

}

Function Button4

{

$Button4 = New-Object System.Windows.Forms.Button

$Button4.Location = New-Object System.Drawing.Point(145, 128)

$Button4.Size = New-Object System.Drawing.Size(100, 25)

$Button4.Text = "4. Auto Shares"

$Button4.add_Click({Auto 

$Form3.Close()})

$Form3.Controls.Add($Button4)

}

Button1

Button2

Button3

Button4

[void]$Form3.showdialog()
}
Catch[System.Exception]{
}
}
}
Get-Choice

The Unhandled exception dialog is not shown but the scripts terminates

So solved this issue by using return instead of exit on code and written to try catch,

Thanks for your assistance @T-Me

Enclose the funcions you call in the Click events in try-catch-Blocks to "handle" the exception: 

Function Button1
{
$Button1 = New-Object System.Windows.Forms.Button
$Button1.Location = New-Object System.Drawing.Point(15, 100)
$Button1.Size = New-Object System.Drawing.Size(125, 25)
$Button1.Text = "1. Folder Permissions"
$Button1.add_Click({
Try{
    Folder
}catch{<# Maybe something here #>}
$Form3.Close()})
$Form3.Controls.Add($Button1)
}
