Hello
The code for the toolbox is provided to you, you can find the C file under ..\CVI\toolslib\toolbox. You will notice that all the functions are just wrappers around the windows api, you can view in the implementation of the registry write methods available in the toolbox, and you can safely add another function to support expandable strings.
I hope this helps
Thanks
