Decouple two features for smaller application sizes

Let's say you make a library, a plugin or just your own set of classes. You use them in various applications, so you add them to your projects. But you don't use all parts always. If you can segment them and maybe help the Xojo compiler, it can strip out unused project items and produce smaller applications.

Use cases may be one project, which can be compiled to both the full version and a demo version. Or a Pro and a Lite version. Or a viewer vs. editor version of the application. Or simply you have a ton of utility classes, but don't need them for the current app. Then you would like to not include all the parts.

We use various of this techniques with MBS Plugin to reduce the size of your built applications. We actively avoid dependencies between plugins as much as possible.

Project Items

The Xojo compiler can strip out whole items in the project. A window that is never referenced in the current version, will be stripped. You can wrap the only reference for one part in a #if section and avoid referencing it in the smaller app version:

#if ProVersion
   Dim e as new EditorWindow
   MessageBox "Please buy Pro version."

You may define boolean constants in a module to do this. Toggle them either manually, via IDE scripting or build steps with scripts. This also helps with target constants to only include some items that are only for one platform:

#if targetWindows then
#elseif targetMacOS

The other module can be stripped. Same for images, classes, controls, windows and other project items.

New Session

Jeremy will come and talk about handling exceptions. Of course you can ask him questions about mobile development as he has a very successful iOS app business using Xojo.

Managing exceptions like a pro
Detecting bugs and fixing them is very important as a developer.
Managing exceptions can take a lot of time to implement. This session will present using an open-source set of classes written in Xojo.

iODBC update needed

Recently a few clients run into a problem with using ODBC databases:

IM004 [iODBC][Driver Manager]Driver's SQLAllocEnv() failed

The ODBC manager (called iODBC) can't load the ODBC driver for the database you like to connect to. By default on macOS we load "/usr/lib/libiodbc.2.dylib" as the ODBC manager, but this library seems to be outdated. (more)

Did you know that you can load extensions in SQLite?

For a few years now it is possible to load an extension both in MBS Xojo SQL Plugin using SQLite as well as into Xojo's built-in SQLiteDatabase. But now we have something new for you here:

You can register custom functions to use in the SQLite database and define them in Xojo.

Andernach City Outlook

Our Xojo conference in Andernach comes closer week by week and we are very excited to host you all in our homeland.

On the last weekend I walked to the Krahnenberg outlook over Andernach. That is a hike you could do if you have an hour or two of spare time in Andernach. The shortest and steepest way is 1.3 km from the Einstein Hotel, but a longer 2.4 km way over road is available or a 2.0 km way along the Rhine and up through the forest.

The biggest plugin in space...
