twinBASIC Update: April 24, 2022
Highlights include updated samples for building custom VBIDE tool windows and custom ActiveX controls that you can drop on Access forms and reports.
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 I boldly predicted that twinBASIC (along with the Monaco editor) would replace VBA and its outdated development environment by 2025.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:

- twinBASIC Discord Server (chat about the project)
Highlights
Improved Template for Building VBE Addins
The twinBASIC Sample 4. MyVBEAddin now includes sample code to create a ToolWindow within the VBA editor.
I will be writing a step-by-step HOW-TO article on the technique shortly, but honestly, the sample is pretty self-explanatory. If you've used tools like Rubberduck VBA or MZ-Tools, you know how much a good VBE addin can boost your productivity.
With twinBASIC, it's now possible for mere mortals to build these sort of custom tools for themselves.
The other nice thing about building VBE addins is that you don't have to worry about deploying them to end users, the way you do with ActiveX controls or COM addins that you reference from within your application code.
VBE addins are a great way to explore the power and possibilities of twinBASIC.

Creating Custom ActiveX Controls with twinBASIC
I published a short how-to article yesterday with step-by-step instructions to create a custom ActiveX control that you can add to forms or reports in Microsoft Access (and, I assume, UserForms in other Office applications like Excel):

twinBASIC Comes to Madrid
My friend Juanjo Luna invited me to present twinBASIC to the Spanish-speaking Access User Group on Saturday, June 18, 2022.
The conference is in-person at the Hotel Preciados in Madrid, though I will likely be presenting virtually. My two years of high school Spanish are nowhere near enough for me to give this presentation in Spanish (at least not without hopelessly confusing everyone), so I will be presenting with the help of an interpreter.
If you are a Spanish-speaking reader that can make it to Madrid, I look forward to "seeing" you there.
Changelog
Here are the updates from the past week. You can also find this information by installing the twinBASIC VS Code extension and clicking on the Changelog tab of the extension page:
Nothing in the VSCode change log this week.
The VS Code twinBASIC extension is currently running v0.14.36 of the twinBASIC compiler. Compiler updates will start getting pushed to the VS Code extension "next week (and then kept in-sync with the compiler updates once again)."
In the meantime, I'm going to list the changes to the IDE beta releases as detailed in GitHub.
