DWord in VB?

I think vb6 only has 3 integer types - a byte (8 bit unsigned), an integer (16 bit signed) and a long (32 bit signed) - you probably will have to use the long if all you need is the range, or the integer if you''re doing declare statements (if you pass -1 in an integer to an api that is expecting an unsigned 16 bit integer, he''ll see it as 65535)

So my best course of action if to use longs (4bytes), and convert them to integers (2bytes) before dumping to the file right?...

VB is so cool as a RAD tool... they should have more basic data types, or at least let us define signed/unsigned ones...

I don't think you can do that assignment directly - you'll get an overflow when you go over 32000, you may have to simulate two's complement to get a value that will fit in the integer.

I haven't worked that much with vb6, so I don't really know if there is a way to automatically do that conversion - if you don't care too much about the size, I'd just use the longs in the file instead.

(And vb .net does have a few more basic types - it will include unsigned integer native types in the next version)
