I have a dll in C++ and I can see it from Qlikview in Custom Data Tab, I am following the SalesForce sample.How can I pass the data to my Custom DLL from Qlikview and viceversa. ?
You would need to build this DLL in particular format with specific interfaces, QlikView can accept. You cannot trigget "any" DLL file from QV.
How did you create your DLL in C++? What did you define as interface?
