Just a few basic questions:

What is the "&" sign used for when I represent numbers?
I know that &H100 is 100 in hex but sometimes I see
a number with an "&" stuck at the end (678&) and some times both at the end and beggining.
Why?

Whrn I exeute a .reg file using "shellexecute", I get the confirmation message box.
Is there a way to execute a .reg file with out this confirmation?

how can I craete a menu on a form using API?


Thanks
Dan.
