In a windows form, I don't want to close the windows but simple hide it, if an user uses Cross (x) button.
I need to redisplay the same windows later on. The $form.close() does also a $form.dispose() and the $form becomes unusable. $form.show() does no longer work

In VB you can workarrount this problem like this

private void Form1_FormClosing(object sender, FormClosingEventArgs e) { e.Cancel = true this.visable = false }
Does any one have a solution for this in powershell ?
Thx

$form1.add_FormClosing([System.Windows.Forms.FormClosingEventHandler]{
$_.Cancel=$true
$form1.Visible=$false
})

Yeah! Just do the same thing: handle the event.
I think you can use $this in the event handler, and you don't need to cast:

$form = new-object system.windows.forms.form
$form.Add_FormClosing( { $_.Cancel = $true; $this.Visible = $false } )
$form.ShowDialog()
# now close it ... it will show "Cancel"
$form.ShowDialog() #yay, it works multiple times!
# now close it ... it will show "Cancel" again ...

Thx. This solves my problem. So simple
