Running FlashBASIC from Visual Basic

When using a FlashBASIC module with the D3 Visual Basic class, D3clsRuleModule, some differences and constraints are applied due to the differences between the Windows and D3 environments.

The topics below outline these differences and provide notes about writing FlashBASIC code to be called from Visual Basic.

  1. Passing Visual Basic arguments
    As detailed in the D3 Visual Basic documentation, only VARIANT variables can be passed to the FlashBASIC subroutine, and any number of them may be passed. Arguments are passed by references, which means they can be modified on return. There are some exceptions listed in the table below.
  2. Passing D3 Visual Basic objects
    The following D3 Visual Basic object handles (using the brHandle method available to each D3 Visual Basic object) can be passed to a FlashBASIC subroutine:
  3. Accessing VME resources from a rule module
    There are several important rules to observe when running a FlashBASIC module, either as a Visual Basic rule module object from a subroutine called by such an object, or from a trigger.
