long shot idea

    So when digging around I found this handy looking dll...

    SmartHMI\CalcMeasurement.dll

    which when imported into VS has all kinds of interesting methods in it. Basically I wanted a method to calculate the best fit tool XYZ given flange positions. And there it was, public with quite clear arguments.

    public double Calc3DToolBy4FlangeFrames(FrameWrapper[] flangeFrame, PointWrapper Tool3D);

    My code compiles and runs but I get an "argument out of range" inside the calculating method, which of course I can't debug further. The inputs seem correct, as I can call methods on them and get data out. I haven't tried any of the other functions.

    My guess is I am missing a dependency(I am no expert but I would expect a different exception in that case). Note I am not running this on the controller, just in a standalone context.

    Here is the code, nothing special...


    using CalcMeasurement;
    public static Frame PlanesToTCP6(Plane[] planes)
    {
    IEnumerable<Frame> frames = planes.Select(o => PlaneToFrame(o));
    //Frame is just a struct XYZABC, similar to kuka
    IEnumerable<CFrameWrapper> cFrames = frames.Select(o => new CFrameWrapper(o.ToDoubles()));
    //the rest of these are types provided in the dll
    FrameWrapper[] frameWrappers = cFrames.Select(o => o.GetFrameWrapper()).ToArray();
    PointWrapper tcpXYZ = new PointWrapper();
    GlobalFuncs myFuncs = new GlobalFuncs();
    double error = myFuncs.Calc3DToolBy4FlangeFrames(frameWrappers, tcpXYZ);<--ARGUMENT OUT OF RANGE IN THIS METHOD.
    return new Frame(tcpXYZ.GetX(), tcpXYZ.GetY(), tcpXYZ.GetZ());

    }

    Open the DLL in Reflector or dotPeek and you can see a reassembled version of the source, look around for some explicit ArgumentOutOfRange throws.

    I believe Reflector will also allow you to step into that method and debug it.

    hmm reflector did help a little, meaning it gets into the wrapper methods. But it still fails at the native call. As far as decompilers go, dotpeek seems much better. It also shows the native method; but I haven't figured out how to step into this(dotpeek is just a viewer, not IDE). Maybe I can at least grasp what going wrong, the native method is several hundred lines long though.
