access function description from c++
 

Hello,

For several user-defined function written in C++, we have
made a help .chm file. Now i have three questions:

1. How can I inlude our own help .chm file in the excel
help file without decompiling the excel .chm?
2. How can I access the function description in the
function dialog box from C++?
3. How can I access the argument description in the
function dialog box from C++?

Thank you in advance
