Hi MJ,

To make it more easy I would use a showdialog.

That goes
dim frm as form2
frm.showdialog
me.picbox.invalidate
frm.dispose

After form2 closes, it goes automaticly back to form1.

If this does not work because a special aproach of you, message it, this is
not the only way, but it is the most easy one

I hope this helps?

You will have to pass a reference to your instance of 'Form1'. The code
above will create a /new/ instance. How this can be done depents on the
structure of your application. The reference can, for example, be
passed in a parameter of a method or in a property of the 2nd form.
