Excel ExcelDNA C# / Try to copy Bloomberg BDH() behavior (writing Array after a web request)

Question

I want to copy Bloomberg BDH behavior.

BDH makes a web request and write an array (but doesn\'t return an array style). During this web request, the function returns \"#

Answer 1

I think you need to implemented the request as a RTD server. Normal user defined functions will not update asynchronously.
Then you may hide the call of the RTD server via a user defined function, which can be done via Excel-DNA.
