Can VBA API be performed in .net?

We are trying to improve the administrative UI to an application we have that uses Excel as a portal to a proprietary DB. All the APIs are written in VBA t开发者_开发问答hus every thing is done in Excel. Rewriting the APIs does not appear to be an option at this time.

Is there anything we an do to use those APIs in the .net environment?

Depending on how your API is set up, it might be possible. See this MSDN article on the topic: http://msdn.microsoft.com/en-us/library/aa159913%28office.11%29.aspx
