xloper structure, excel
 

I have a question about using the xloper object when creating a C++ dll that
is called by Excel. So say I want to pass in two ranges from my excel spread
sheet (A1:A10 and B2:B11).



c_range_function (xloper a, xloper b);



now from the excel spreadsheet or VBA how do I pass that range into my C++
dll function so it recognizes the range.



would it be something like in the excel spreadsheet use the formula



=c_range_function(A1:A10, B2:B11)





There are also other types of "excel structures" like xl_array and a bunch
of excel types. How do they factor into my program.





Thanks,

Aaron
