Huge Memory Leak with inputbox?

is inputbox still being used?

Code:

---

  'Dim productKey = InputBox("Enter new product Key", "New Product Registration", String.Empty)
        Dim productKey = productKeyTxt.Text.Trim

        If Not String.IsNullOrEmpty(productKey) Then
            'if product key is valid, then register the product

            Dim Lic As New License
            Lic.passkey = PassKeyLbl.Text
            Dim IsValid As Boolean = Lic.validateKey(productKey)
            If IsValid Then
                My.Settings.productKeyRegistered = True
            Else
                MessageBox.Show("Product Key is invalid")
            End If
        End If

---

as you can see I have it commented out on the first line.

I am using the small Licnese class in the codebank. Thanks for whoever submitted it.

Anwyas, everything works fine when using a textbox. When I throw the input box in my app hangs. for example, NO exception is thrown. the computer slows down to pretty much where I have to restart. I can't click anywhere, and if I do i gotta wait about 30 minutes until the process is executed.

Has inputbox been buggy for people before? Is there a reason Why is does that?

* I 've been using inputbox for some other sections of my app, and they seem to go okay.

Do not use InputBox.

Make your own custom form to get the Product Key. This won't hurt you anyway. Just a piece of advice.
