Access XLL functions from C# winform

Mar 28, 2011 at 2:31 PM

Hi, Govert,

Thank you for the excellent work.

Now, I want to call the Excel XLL addin functions from my C# winform project. If the addin functions without XLOPER variables, they work fine. However, I can't access the addin functions with the XLOPER variables. If I use your Excel-DNA, can I call these addin functions from my winform application? Any suggestion?

Thank you in advance!

Hi Jack,

Do you mean to access the functions in an .xll without having Excel involved? If so, Excel-DNA won't be able to help you (though you could find some bits in the code useful to marshal XLOPERs and make your own wrapper).
