Thats confirms what I was thinking.
I compile my apps compleetly before distributing, so I supose while
developing it's best having both options on?

Onderwerp: RE: [AccessD] Compile options in VBA.

The Compile on Demand is an option that either compiles your code in
it's entirety when your application starts (the option would be off for
this..), or compiles it when it is required (when you have Compile on
Demand on). The big difference is startup speed.  If you project has a
lot of code, if you don't use 'Compile on Demand', you are going to get
a startup delay as Access compiles the VBA code.  The second option
(background compile) is a subset of compile on demand.  If you have
compile on demand set, you can use the background compile option to have
Access compile it's code during idle time periods.

The reason you have these options, is because VBA is a 'higher'
language, which means it makes sense (or it should...) to a human.  But
the CPU itself still requires machine language to be sent to it, so your
VBA code must be compiled into machine language, in order for the CPU to
carry out your instructions.  I wonder if you have the Compile on Demand
turned off, if you wouldn't be allowed to make changes to code on the
fly, when the application is running.  Hmmmm.....

Anyhow, I don't see a real reason to not have both options checked.  If
you want your code to be compiled all the time, use an .mde.

Hi
 
I was wondering something.
In the VBA editor in options>common(?)>Compile You can click two options
for compiling.
I have the dutch version and I find that the help is poorly explaining
the exact use of these options (if not for everything:-(.
Compile at request and background compiling.
 
I wonder if anyone could explain me what those options do and what best
choice is...
