This DCDT+ source code was compiled with Microsoft Visual Studio 2019 Community Edition. Note that compilation of this source code requires two commercial third-party add-ons: 1) the Gigasoft ProEssentials graphing package (used to generate all the graphs) 2) the Resize .NET component from Larcom & Young, which rescales all the elements on forms and dialog boxes as that window gets resized This code also uses a custom control, MyControls.dll, which provides customized versions of the Gigasoft scientific graph control, the RichTextBox control, and a version of the TextBox control specialized for inputting floating point numbers. The source code for MyControls is located in a sub-folder of this DCDT+ source code folder.
