I want to call a dot net library from Excel 2007 VBA. I tried following the
following article:
http://richnewman.wordpress.com/2007...ry-from-excel/

It helps me in building a library and I am able to set a reference to the
dot net library and access methods. However, when I try to execute any VBA
function, I get an automation error inside VBA. The execution point never
jumps into the dot net library. If there is any solution please help me to
solve this issue.

Thanks in advance.
