Minimal example of module class

[Petr Schreiber]

As the ThinBASIC 1.8.8.0 introduced the module class concept, and some users start to experiment with it, I attach here very simple example of module exposing class.


The PowerBASIC module code, contained in thinBasic_Vector3D.bas, defines the Vector3D class with constructor, destructor and single "normal" method, called ToString
The ThinBASIC test code, represented by thinBasic_Vector3D_Test.tBasic, shows how to instantiate and use the created object

It is very simple project just to demonstrate few important steps in module class creation:

creating internal COM representation
creating visible interface to it via thinBasic_Class* SDK functions
creating wrapper functions/subs for methods, taking care of instantiation, release and parameter parsing (same as in normal modules)

Thanks Petr.
Can you do MSVC same or other minimal example for module class? Perhaps FreeBASIC?

[Petr Schreiber]

Hi Maxim,

I am sadly not familiar with C or FreeBASIC approach to create COM classes, maybe other guys will know better.
I know that you can create classic modules (without classes) quite easily with FB, C (as seen in ThinBASIC/SDK samples), but the classes are new thing to the SDK, so no examples are present at the moment.

One of the guys you advise?
