VBA extension modules

These modules are a collection of useful functions and subroutines for Visual Basic applications. General purpose was to make readable code, extend VBA functionality and to speed up developement.

Module name	Description
libcore	Contains utility functions for VBA language. Type extensions: Array, String, Path, Directory, File and more.
libexcel	Contains utility functions for Excel types. Type extensions: Workbook, Worksheet, Range...

Important

Target OS is Microsoft Windows.

libcore has functions that reference Excel functions. These functions will create an Excel application, if needed. libexcel module references libcore module functions. Don't forget to import both when using libexcel.

How to

• Import modules to your projects, or copy specific functions,
• Function names start with the name of the type they intended to extend,
  • Array functions start with the word 'Array...()', ex. ArrayDimensionCount(),
  • Range extensions start with the word 'Range...()', ex. RangeIsEmpty(),
  • and so on...
• Functions use late binding so it does not require you to add library references,
  • I recommend using early binding, but late binding allows you to manage application behaviour,
• Most Excel extensions don't mess with ScreenUpdating or EnableEvents properties (unless needed),
• Excel sheet, column & row parameters are variants,
  • You can either use string, number or object references as well,
• Some functions raise errors, make sure to handle them,
• I don't use RubberDuck, but i did leave RubberDuck annotations to describe functions/modules,
• I tend to trigger errors to check valid data (some might find it a bad habit),
