twinBASIC Update: June 19, 2022

Highlights include improved support for 3rd-party ActiveX controls, a new location for tB IDE releases, and a discussion about where to put non-visual controls.

twinBASIC Update: June 19, 2022

On April 23, 2021, I helped Wayne Phillips introduce the world to twinBASIC at the Access DevCon Vienna conference.  I boldly predicted that twinBASIC (along with the Monaco editor) would replace VBA and its outdated development environment by 2025.  With that goal in mind, this weekly update is my attempt to keep the project fresh in the minds of the VBA development community.

Every Sunday, I will be providing updates on the status of the project, linking to new articles discussing twinBASIC, and generally trying to increase engagement with the project.  If you come across items that should be included here, tweet me @NoLongerSet or email me at mike at nolongerset dot com.

Here are some links to get involved with the project:


ActiveX Controls: Massive Improvements and Bug Fixes

Based on the activity in the Github project, it appears the main focus of Wayne's efforts over the past week centered around improving support for embedding third-party ActiveX controls on twinBASIC forms.

For example:

New Location for twinBASIC IDE Releases

The mega-IDE thread has been locked.  From moderator Ben Clothier:

Note: As per discussion on the discord, the thread will be now locked. The feedback will be split off into their own issues to aid tracking and avoid sprawling and potentially missing issues reported. If you have any issues to report about the beta, please open a separate issue going forward.

Furthermore, we are looking at improving how releases will be handled so do keep a eye for further update on how new releases will be announced here. Thanks!

And here is the aforeshadowed* announcement from Wayne:

From now on, all new releases will be uploaded to GitHub and available at the following link:

* Yes, I made this word up, but I think it fits in this very specific situation.

Section for non-visual controls

Ben Clothier opened up a discussion about how best to handle "non-visual" controls on twinBASIC forms.

For example, in Access and VB6 a timer "control" gets added to a form with layout properties like "Left" and "Top" despite the fact that the control will never be visible to the user at runtime.  This same behavior applies to certain ActiveX controls, such as third-party TWAIN controls for integrating with hardware scanners.  It's always felt weird to me that these types of controls–that cannot be made visible to the user–must still get laid out somewhere on the form in design view.

Of course, if you don't put those controls on the form grid somewhere, where do you put them?  That is an interesting question indeed.


Here are the updates from the past week.  You can also find this information by visiting the GitHub twinBASIC Releases page.
