Converting video formats

This year’s major project at Field Precision is educational — a full-length video course on how to calculate static electric and magnetic fields with finite-element methods. Of course, the sub-context is the essential techniques and insights to use our software effectively (e.g., how to design meshes for maximum speed and accuracy…).

In preparation, I updated my copy […]

Xojo (nee RealBasic) supports them, but it is not immediately apparent how to use them effectively. This article discusses options to fine-tune the user experience.

A HelpTag is the easiest way to create a help […]
