[RESOLVED] Data type sizes constant?

In Visual Basic 6, are the sizes of data types constant on every version of Windows?

I know in C++, the sizes are not guaranteed (ie: an integer may be 2 bytes on one system, 4 bytes on another).

Is there any real need for the LenB() function or are they always the same?

VB6 compiles only 32-bit executables, no change in data type sizes.

Thanks.
