Hi There,
If I create a com addin, I'd like to show the parameters when the user types the function name and open parenthesis (exp. "=functionName(" ). For example, I want to show the "vlookup(Lookup_value, table_Array, col_index_num, [range_lookup])" to remind the user which parameters they need to type in when you type "=vlookup" in one cell. (I am not sure whether I explained clearly or not :-(, hope you all understand what I mean
How to get this kind of trick. Thank

Best Regards

Lee
