Hi all, I want to use a Python function that returns a double array in VB dot net via embedding Python in C++ dot net. Using the CLR it is easy to access C++ from VB. Then also I don't have a problem if the Python function returns a single variable of type double, using the following lines in my C++ code: myPythonObjectPointer = PyObject_CallObject(pFunc, pArgs); myCppDoubleVariable = PyFloat_AsDouble(myPyObjectPointer); (I have obviously done all the required thingies as per the Python documentation) I can further achieve what I want by changing the Python function to a number of functions, each returning a single double variable and call them one by one, using code like above, and then passing them into an array in C++, but I would prefer a more elegant way of doing it, because my return variable could have hundreds, if not thousands, of values. Can somebody help me please. Thanks Pieter Steenekamp.
