[dba-VB] VB.Net XML - store form defaults

Oops. Copy and paste error in the code I sent. The variable regPath should be 
the same in both the form open and form close events, and in the code I sent 
it wasn't. I copied the code out of a form where I do other things with the 
registry too, and copied the wrong line where the value of regPath is set for 
the form close event. Sorry.
