twinBASIC Update: March 5, 2023

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  I boldly predicted that twinBASIC (along with the Monaco editor) would replace VBA and its outdated development environment by 2025.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:


Highlights

MonthView and DatePicker Controls Added

They can be found in the "WinNativeCommonCtls" tab of the form designer.

The date picker control is shown in red in the screenshot below and the month view control is shown in cyan.

New Methods, Properties, and Events

  • added: support for PaintPicture method on Form/PictureBox/UserControl
  • added: support for Form/PictureBox/UserControl Scale method
  • added: support for CausesValidation property and Validate events for all native controls

Around the Web

Hiding the twinBASIC Splash Screen

Over in GitHub, someone asked if there was an option to turn off the splash screen:

When I run compiled console app, the splash screen "twin Basic" is appearing.
Is it adjustable, to turn off?

This is likely a common question for many new users.  It's something I haven't mentioned on this site in awhile since it's not new functionality.

Longtime commenter FullValueRider provided the answer:

Easy.  Just buy a license.  The 64 bit community version has the splash screen.

If you need to hide the five-second splash screen in 64-bit builds–or if you'd just like to support the project–you can purchase a pre-order license here: https://twinbasic.com/preorder.html

That page also includes feature comparisons between the three available licenses:

  • Community (free)
  • Professional
  • Ultimate

This is also probably a good time for a periodic reminder that I am not a developer on the twinBASIC project, nor do I have any financial stake in the company.  I'm just a longtime Access developer with high hopes for what twinBASIC could mean for the Access community.

And if you'd like to learn more about the longterm plans for Access and twinBASIC, be sure to register for the upcoming Access DevCon Vienna online conference, where I will be presenting on the topic, "Exploring the Future of twinBASIC and Access Development."
