The joy of decompiling...

[Deano]

Just wondering if there is a tool or method that will allow me to compare
the state of my database before and after I decompile it.

The last time I decompiled a few fields lost default values and some event
code wasn't firing anymore. I know that sounds unusual but this was
definitely the case.

I would like to decompile again but am reluctant to do so if it causes any
more problems. I would like to test what the decompile does to my database
by being able to accurately determine any subsequent changes in form
controls, table fields etc.

Any suggestions?

thanks
Martin

Er.... Default values are stored as column attributes. AFAIK, they are
nothing to do with the VBA Project (which is what the decompile alters). I
really can not see decompile affecting default values.

There is no way you will make any sense of a before/after comparison of the
mdb file. Most of the information is stored in binary structures. You will
not make any sense of *one* file - let along a before & after comparison -
unless you understand those structures: none of which are documented.

After I decompiled all this hair started growing out of my ears.

That's kind of what I want to hear. But a key table did change after the
decompile. I certainly didn't go in and amend it. Very odd, I know I can't
prove that decompiling screwed it up - at the moment - but was hoping that
if I could record the state of play before decompiling then I could do a
comparison.

I meant like a thorough printout of all objects in the db and their
attributes.

Tools - Analyze - Documenter

This creates a report of all of the objects (user selectable) with all of their
properties. You could create one before and after for comparison.

You could do that by writing some code. Or, I'm sure there are commercial
products. So before the decompile, run the code (or product) to create a
flat-file dump of the database structure. Then do the decompile, then run
the dump again to different files, then use a file-compare program to
compare the two versions. Or the other respondent's suggestion of
Tools:Analyzer might work also.

Thanks for the responses. I can't believe I missed the Documenter. I ran
it for all objects and got a report that ran to 2450 pages!!
Think I'll trim that down a bit.

Gak!

Perhaps write some Word VBA to cut it down somehow? (delete blank lines,
page breaks, whatever)

So you could probably still automate the comparison process.

Yeah I now, Containers and all that malarkey; I haven't got the will to do
it. I did select All objects and that wasn't strictly needed. I wish there
was some sort of checksum that 'proved' the file you started with is the
same you have after the decompilation process. Or maybe version control
software could help (SourceSafe??).
