[Gambas-user] gb.db.form driver missing

[Michael]

Tobias,
I am presuming this form is your startup class, in which case you are 
trying to utilise the Db Connector before your resources are fully 
loaded. It might not happen if you use this code in a form lower in the 
hierarchy.
Personally I keep all Db access in a separate class called "data" which 
handles all communication with the database. I then start my apps with a 
"Main" module not a form. The Main module will load resources (such as 
Db Connector), test the Db connection, check password etc, and only then 
load the first form in the hierarchy.
Hope this helps.

Again, a personal preference, but my top level form is always just to 
hold a menu and a status bar. Any actions are being handled by creating 
sub-forms for each menu. This pretty well ensures that the main form is 
loaded before any errors are generated and it gives you a template to 
create a main menu form for any future projects.

Regards
Michael
