AutoCAD Inventor :: Simulation Results In API?

I'm developing a program which runs several simulations and obtains the results automatically.

I'm using the dynamic simulation API created in Inventor 2013. For that I use the GetResultValues(ByRef values() as Double) method of the class DSResult. 

I used the method inside the VBA of inventor and worked well. But when I wrote the program in Visual Basic Express 2010, the method doesn't return anything.

I share an excerpt of the

Dim odoc As AssemblyDocument
odoc=invApp.Documents.Open(testPath, True)
Dim dsman As Inventor.SimulationManager = odoc.ComponentDefinition.SimulationManager
Dim dssim As Inventor.DynamicSimulation = dsman.DynamicSimulations.Item(1)
Dim oJoints As Inventor.DSJoints = dssim.DSJoints
oJoint = oJoints.Item(1)

[code]....

The method GetResultValues(values) should modify 'values' to a time,value vector.

It works well inside Inventor, but doesn't in the program in VB, although it runs the simulations and does everything else right.
