Clear Out Data When Unloading Forms

When unloading a form, use the following piece of code behind a Close button:
 Unload <formName> 
This code should also be put in the Form_Unload() event handler for that form:
 Set <formName> = Nothing 
This clears out any remaining code/data in the data segment for the form, if you don't do it explicitly. This is important when you load/unload many forms, especially those with lots of controls. By the way, this is not a bug--it's done this way by design. The same is true for VBA--if you don't initialize global (module) variables in VBA (for Excel, for example) and have this kind of expression:
 i% = i% + 1 
then i% will successively have the values 1, 2, 3, . . . as you run the VBA script one more time. Again, by design.
