I'm impressed - I've copied my accounting system tables across from
Access into mySql and I've actually created a minimal Dabo application
which shows the invoices. It hasn't been too much effort and I
haven't had any of those "what on earth does that error mean" moments,
I could actually understand all the errors and was able to fix them.
Most of my mistakes were simple typos and/or failure to change things
to match my tables etc. when following "The Step-By-Step Guide to Dabo
Programming" (it's an excellent tutorial by the way).
So, now I have a form displaying some data, next steps will be adding
some buttons, other controls, etc. but before I go further some minor
things I'd like to clear up....
1 - I'm getting a warning message saying:-
Dabo Info Log: Mon Oct 6 21:29:40 2008: WARNING: No BasePrefKey has been
set for this application.
What's this telling me? Also, is the python traceback that follows it
referring to the above warning or is it quite unconnected? If it's
relevant the traceback says:-
Traceback (most recent call last):

2 - The data from my Invoice table has some output formatting oddities
when shown in the Dabo form:-
Dab seems to think the InvoiceNumber is a 'long', i.e. it appends
an 'L' to it.
Although mySql shows all the dates with a time of 00:00:00 Dabo
shows them as 12:00:00 AM which is rather an odd time!
I guess these are probably easy enough changed by playing with the
formatting properties of the controls on the form though, they're
hardly important.
