WLExt is a free library of utility functions for Wealth-Lab (R) exposed through COM Automation.

wlext.dll exposes a number of simple utility classes as COM interfaces that can be used from Wealth-Scripts (C).

Installation:
copy the wlext.dll to the desired directory and then run the following line from the command window: regsvr32 /v [path]wlext.dll, where [path] is its location.

I tested wlext.dll on on Windows 2000 and 98SE, and it worked fine.

The only classes available at this moment are Array1, Array2 and Array3 which implement mono, bi and tri-dimensional dynamic arrays of floating point values. Dynamic in this context means that they are created and their size is defined at runtime, but they cannot dynamically grow (as a vector type of container would). Once the size is set, it cannot be changed.

It currently offers very basic functionality, but it is quite easy to extend, and I am planning on adding more containers classes that are useful but currently not available.
