Dear Marcia,

First, how could you catch the public variables?! by its names?! Then, theorectically, all memory variables can be catched... also, even the code embedded in the executive programs can be decoded?! What is the point of security here...

Second, I try your method, but it seems not working...

In load event, _screen.activeform is not formed yet, so it is not an object... also, oParent is a variable which need to be defined before use?!

Sorry to bother. Just want to know more about different views... I couldn't make your suggestion works
