You should be using a Variant which includes Double arrays - not a Variant array or a Variant containing an array of Variants.

The process of using VC++ 6 or Borland C++ Builder 6 to pass data through Variants is quite complex. We do include samples with source code for VC++ 6 in our licensed software, but due to the amount of work involved, this is one sample application that we don't provide with just the trial version.

On the other hand, if you can use VB 6, VB.NET or VC# the trial software can be used and the whole data processing is much simpler.

Mostly this process of using Variants is transparent to the user. The time when this will surface is in creating applications in Visual C++ 6. Please contact us if you do need to see a demo application using this environment. We include special functions which make it easy to pass data arrays to and from the components. Once you have purchased a license, you a permitted to use the code within our demo programs in your own applications.
