How do I use a dll in Vizard

[shall6]

Hello - I'm having a slightly different problem with a DLL. It imports fine, but when I try to call a function created in the dll, I get an error that there is "No such attribute" in the module. The dll is called RRG.dll, and it includes several functions, one of which is CreateRobot, so what I'm trying to do is

input RRG

robot = RRG.CreateRobot('input1',input2)

The dll is included in 'bin' and a similar dll compiled for use with the same program in Vizard 3.0 worked just fine. The syntax in the program itself and the new c++ code was updated for Vizard 5.

Anyone have any ideas? Is the dll in the right location? How can I get the functions to be recognized?
