Local External Functions

Local External Functions

Question:
Instead of distributing a user object (and its functions) as a PBD, I want to distribute it asa DLL (build runtime library, machine code),and then access its functionality in other PowerBuilder applications by using the Declare ..Local External Function syntax. The application seems to recognize the DLL file (I have registered it in the NT registry), because if I incorrectly name the functions in my external function declaration, I get an error (“Error calling external function “). However, if I provide the correct name, I get the error “Error calling external function” (no function name is given).

Can Powerbuilder code DLLs be used as local external functions in other applications, or must I distribute PBDs instead?

Answer:
You have to use PBDs. You cannot make external calls to PB DLLs.
