Chip,

Thanks for the explanation. Just what I was looking for.

Regards,
Mark

Mark,

VBA Code is never stored as the plain text you see in the editor. It is
stored as platform/version independent byte-codes, call OpCodes. These
codes are converted to text as you edit the module. When you compile VBA
code, the OpCodes are translated to platform/version dependent
instructions called ExCodes. These ExCodes are read by the VBA runtime
library to carry out the actions of the code. The reason that a compiled
project is larger is due to the presence of ExCodes.

Charles,

Thanks for you reply. Yes, that appears to be the case. He did not
compile the code, as I always do. I'm unable to locate anything in
Microsoft Support that explains exactly what happens during this Compile
process that makes the files so much larger (other than a brief
explanation of how it does syntax checking, which is the main reason I
compile). Do you know where I can get more details on the Compile
process?

The compiled Add-In does not show any noticeable performance improvement,
so I'm wondering what takes place to cause such a huge increase in file
size (4MB to 6MB).

Thanks again,
Mark

Mark,

probably he did not compile the code.

BTW you should be using Rob Bovey's Code Cleaner (if you arent already)

All,

I am currently using Excel XP (SP3) and created a complex Add-In, which
I passed along to another programmer. The other programmer opened the
Add-In and made a very minor VBA code change and then saved the XLA.
The file size of the XLA shrunk from 6MB to 4MB. He is also using
Excel XP (SP3). I ran a Sourcesafe compare on the code modules and
they are all identical (with the exception of the two lines he
changed). There are a few hidden worksheets, that are also unchanged.
Does anyone have any idea what would cause such a huge change in file
size?

Thanks,
Mark D'Agosta
