Actually thats a good idea (and simple too) - thanks

It is is also common in Win32 programming where many Structs contain a
'size' element. This element is less important in VB than it is with
languages that can vary the pack size. But is important where 'size' is part
of the mechanics.

If this is two VB6 applications running on the same box, where you have
complete control of all the source - you might check out DDE. It is natively
supported, simple, quick to instrument, and provides built-in exception
handling.
