In the March/April issue:
*Numbers Please!* by Markus Winter
Creating a numbers-only textfield sounds easy, but as Markus demonstrates, it's trickier than it looks.
*Dynamic DLL's* by Eugene Dakin
If you're on Windows and need help managing DLL's, Eugene shows how to load them dynamically in your Xojo apps.
*More Beyond JSON* by Tim Dietrich
Last issue Tim showed how to create an API to generate barcodes. Now he's back to demonstrate an API for charts and graphs.
*Alternating Row Colors for Dark Mode* by Christian Schmitz
We've been making alternating row colors for our listboxes for years—but that was before Dark Mode. Suddenly it's a tricky problem, but Christian has the answer.
*Rotating a Cube* by Eugene Dakin
Some people think Xojo can't do graphics, but here's a great demo of a rotating 3D cube in pure Xojo code.
*PLUS*: Creating custom events, XDC 2019, new Xojo docs, Flashing windows on Windows, MarkdownDS, Best of the Web, and more!
