Segmenting an application

I have an application that I want to be able to include some "optional"
components into. Currently the application is one big image and ideally
I would like to not have the optional pieces increase the image size
etc.

What techniques have people used to modularize applications?


thanks,

pete

A VFP exectuable can call VFP code compiled as COM-server DLL files or as
APP files.

Pete,
Just to add to Anders information, if you do this, it's a good idea to =
add version checking capabilities to your APPs and/or VFP COM =
components. Otherwise you may find yourself trying to figure out =
"problems" that are due to users restoring or copying around "old" code =
files.

Can these include forms etc?

VFP .DLL's don't support a user interface, you have to use VFP .EXE
automation servers for that. Not sure about .APP's.

Hi Peter,

how about dividing the whole thing into several Projects, compiling
them as EXE-Files and then calling your classes via "NewObject"?

I'm running the same thing with EXE-Files in a subfolder to my MainApp.
Releasing he class from memory when it's not needed at the moment,
enables me to change whole user-interfaces during runtime.

HTH,
Pierre

APPs execute in-process and can include forms.
COM DLLs execute in-process but can't include any visual interface.
COM EXEs can include forms but execute out-of-process.

For segmenting an application into logical components, using APPs
is by far the simplest approach and is seamless from an end-user
perspective.
